Transformer Oil Leak 

Repair 

One Minute Epoxy / Flexane® 80 Putty 

2/14/96 

B. C. Hydro 

Utility Power Distribution 

Problem: 

Inspection of 4Kv and 12Kv transformers revealed excessive leaking oil from both the bushing, flange 

and fastener areas. The leaking was so severe that either side of the transformer tank was covered with 

a thick film of oil. De-energizing and installing new gaskets would require a 6 week shutdown. 

Shutdown and repair cost was estimated to be $70K. 

Solution: 

Leaking or repair areas of the transformer were sandblasted to a SSPC-SP5 white metal finish. One 

Minute Epoxy was applied to plug all active leaks. Following confirmation that all leaks had stopped, 

repair areas were chemically cleaned using Cleaner Blend 300. Both FL10 and FL20 Primers were 

applied and each allowed to cure or dry for 15 minutes. Using both primers will improve Flexane 80 

Putty adhesion from 25 pli to 50 pli. Flexane 80 Putty was applied to a thickness of 1/8”, extending 

beyond the One Minute Epoxy by 1-2 inches. GoJo hand cleaner was used to smooth and sculpt 

Flexane 80 Putty following gel point. Devcon’s repair cost was $4.5K with only a 3 day shutdown..

Canada Cement Lafarge 


Problem: 

These pneumatic conveying pipes would receive extreme abrasive wear from processing fine cement 

particulate. The previous method of repair was to fabricate new pipes. Fabricating new pipes was an 

expensive repair procedure and caused flange and fastener misalignment when re-assembling due to 

heat distortion. 

Solution: 

Repair surfaces were sandblasted to a SSPC-SP5 white metal finish. Surface area was then chemically 

cleaned using Cleaner Blend 300. Ceramic Repair Putty was applied to worn areas deeper than 1/8”. 

Following a partial cure of Ceramic Repair Putty, (4 hours), Brushable Ceramic was applied to a 

thickness of 25 mils. Following a partial cure of Brushable Ceramic, (4 hours), a second coat of 

Brushable Ceramic was applied a 25 mils. . Brushable Ceramic encapsulated the repair areas and 

provided a long lasting, abrasion resistant, protective surface coating.

Expansion Joint Repair 

Flexane® 94 Liquid 

2/11/97 

Hyundai 

Construction 

Problem: 

Undersea road support structures required moving onto a submergible barge for placement into the sea. 

To provide a smooth and level surface on the barge deck, ITW Chockfast was used. Due to the enormous 

weight of the support structures, and the flexing of the barge from rolling seas, cracking occurred. 

Surface cracking and hollow, uneven expansion joints caused extreme difficulty when rolling the support 

structures onto the barge. 

Solution: 

Because of extremely high compressive strength and excellent flexibility, Flexane 94 Liquid was used to 

fill expansion joints and repair cracked areas on the barge deck. Crack and expansion joint areas were 

roughened and then chemically cleaned using Cleaner Blend 300. Expansion joints were filled or stuffed 

with a polypropylene backer. This prevented Flexane 94 Liquid from migrating deep into the concrete. 

FL20 Primer was applied and allowed to cure or dry for 15 minutes. Flexane 94 Liquid was poured into 

the expansion joints and cracks. Flexane 94 Liquid provided a smooth, flexible, (350% elongation), level 

surface allowing the structure to be moved easily and safely.

Problem: 

Undersea road support structures required moving onto a submergible barge for placement into the sea. 

The structures enormous weight needed to be supported and moved onto the submergible barge. 

Common rubber could not be used as wheels due to low compressive strength. Common rubber would 

lose it’s cylindrical shape and cause the structure to seize when moved. 

Solution: 

Because of extremely high compressive strength, Flexane 94 liquid was molded and manufactured into 

wheels and as compressive shock absorbing pads. Flexane 94 Liquid easily supported the weight and 

allowed the structure to be moved easily and safely. When manufacturing parts, Devcon Release Agent 

must be used for easy part removal or separation from the mold.

Coal Dust Valve Repair 

Titanium Putty / Brushable Ceramic 

2/15/94 



Problem: 

Fine coal dust particulate would cause extreme wear to the seal areas on this valve. Because the wear 

was 1/8”, the seal was compromised allowing coal dust to seep through the valve when in the closed 

position. 

Solution: 

The repair area was roughened using a grinder and wire wheel attachment. Repair area was then 

chemically cleaned using Cleaner Blend 300. A generous coating of release agent was applied to the 

butterfly valve. Titanium Putty was mixed and applied to the valve body, rebuilding the missing metal. 

The Titanium Putty was smoothed, sculpted and feathered using acetone. The butterfly valve with 

release agent applied, was closed and used as a forming mold. Following a 4 hour cure, the valve was 

opened. Three coats of Brushable Ceramic were applied totaling 25 mils. Brushable Ceramic 

encapsulated the repair areas and provided a long lasting, abrasion resistant protective surface coating.

Problem: 

Concrete motor pad becomes broken up after intense vibration of pump motor vibrating over time. 

Broken and spalled concrete needed to be removed and the area cleaned of all loose fragments. A 

wooden form will be placed in the area to be rebuilt, spanning the spalled area of the motor pad. Then a 

new set of anchor bolts placed to secure the motor. 

Solution: 

After the loose concrete was removed from the surface, a pine form was anchored in place using 1- 

Minute Epoxy to secure to concrete an d seal area from any grout traveling under the form. Then Deep 

Pour Grout was mixed and poured into one side of the hole. The material moves freely displacing air as 

the grout fills all crevices. The material self levels nicely for a smooth finish. A anchor bolt is placed 

into the grout approx. 20 minutes after the pour. After 24 hours the motor is mounted back onto the pad.

Sprayable Ceramic Ceramic Repair Putty. 

February 98 

B G & E Power 

Power Plant 

Problem: 

Rebuilt intake water circulating pump that has been worn through caviation over the years. The veloute 

areas have seen quite a bit of erosion of metal. The pump is so large that the plant wants to spray a coating 

onto the surface for easy of application for the mechanics 

Solution: 

First the pump area is sandblasted to a SSPC 10 finish. Then degreased using our Cleaner Blend 300 which 

leaves no residue. This leaves a good 3-5 mil profile for application of our materials. Ceramic Repair 

Putty is applied to the large spalled areas of metal over 1/8” deep. This helps to fill in these worn areas. 

Next the Sprayable Ceramic is coated at a 20-30 mil coating in one pass over the entire pump. A wet film 

gauge is used to gauge the thickness. After 6-8 hours a second coat of the Sprayable Ceramic is coated 

onto the pump for a finish of 40-60 mils. This makes for a strong chemical and abrasion resistant coating.

Flotation Cell Repair 

Brushable Ceramic and Ultra Quartz 

January 1998 

Noranda Mine (Brunswick Mine Division) 

Mining 

Problem: 

Floatation Cells see tremendous corrosion by the fact that the ore is abrading the sides of the tanks 

constantly! Any coating you apply must have great abrasion resistance. Galvanic corrosion occurs at the 

steel surfaces rather quickly once abrasion starts! The floor of the Floatation Cell sees the sediment of the 

ore which is very abrasive, and needs repairing regularly. 

Solution: 

The Flotation Cells are first blasted to a SSPC -SP5 white metal blast to remove all corrosion from the 

surface. Any large holes are filled in with Titanium Putty. Next Brushable Ceramic is rolled onto the area 

using a 1/4” nap roller. Two coats are recommended . Each at 14-18 mils thick. Between coats the 

coating is checked for a “holidays” with a Leak Detector Kit. The finish coating provides a tough durable 

abrasion resistant finish against the aggregate. The floor is troweled with 3/8” of Ultra Quartz for final 

protection. The Ultra Quartz is troweled up the side wall approximately 4 inches for a seamless finish.

Newmont Gold 

Mining 

Problem: 

The mating area between the ball mill shell and the head would receive extreme wear from an abrasive 

slurry washout. The wear was so severe that the metal was worn in excess of 1/8” deep. 

Solution: 

The complete repair area was roughened using a grinder and wire wheel attachment. Following 

roughening the complete area was chemically cleaned using Cleaner Blend 300. Eight holes were drill 

equally spaced around the diameter of the mating area. The mating area void was then sealed from the 

outside using PorRok. Sealing the mating area void eliminated any migration or flowing of Plastic Steel 

Liquid. Plastic Steel Liquid was then mixed using a drill and mixing tool. Following mixing, Plastic Steel 

Liquid was poured into the mating area void using a funnel. The funnel improved flow rate. Pouring 

started at the lowest point injection holes. A steel plate was welded over the holes when the Plastic steel 

would reach the hole. This process continued until the void was completely filled. Replacement of the 

Mill Head was estimated at $160K. Devcon cost of repair was only $10K!

Floor Repair Acid 

Environment 

Floor Patch - Ultra Quartz - EC7000 AR 

6-12-99 

Alcoa Aluminum 

Processing 

Problem: 

In the processing of aluminum in making cans, high concentrations of acids are used. These acids are 

contained in large tanks and used in groups in containment areas. These containment areas see “spills” 

which cause the concrete to be “eaten away” because of chemical attack. This application shows up to 

12” deep“trenches” into the concrete which harbors the acid in these pools, attacking the concrete even 

more. 

Solution: 

First, the floor was rinsed multiple times with water to “neutralize” the acid condition of the floor. After, 

dried Floor Patch was used to fill the large trenches, (12” deep), in the concrete around the tank areas. 

Before the Floor Patch cures, our chemical resistant Ultra Quartz was used to apply a final ¼” topcoat 

onto the entire surface for ultimate chemical resistance to the acid. All drains and sloped areas were 

shaped at this time for good drainage. Then a coating of Epoxy Coat 7000AR (12-15 mils) was applied 

over the entire containment area for acid resistance. This tank area is now protected for any spills that 

may occur.

Brushable Ceramic 

3-15-99 

Syncrude, Ft. McMurray 

Mining 

Problem: 

In mines, water feed pumps “wear” because of abrasive particles flowing through the volutes at 

tremendous speeds, causing wear and abrasion inside the volute and impeller areas. Pump casings are 

very expensive and instead of “replacing” the volutes, metal-filled epoxies are used to rebuild loose metal. 

These polymers act as better “wear resistant” finishes on the surface. In this pump, the volute areas had 

wear up to 1” deep, which had to be filled before a protective coating could be applied. 

Solution: 

The volute of the pump casing was sandblasted to an SSPC-SP5 white metal finish. After blasting, the 

pump was cleaned with our Cleaner Blend 300 to remove all residual abrasive shot from the surface. 

Then a primer coat of Brushable Ceramic (12-15 mils) was coated on all areas. Immediately after coating 

with Brushable Ceramic, the large voids (over 1” deep), were filled with Wear Guard High Load. The 

Brushable Ceramic acts as a primer helping the beaded epoxy adhere better to the surface. Next, Ceramic 

Repair was used to fill all other voids (under ½” deep). Finally, a topcoat of Brushable Ceramic (12- 

15mils) was used for a smooth, final chemical resistant finish.

Brushable Ceramic White (Food Grade) 

12/12/94 

Siftco Canada Incorporated 

Agriculture Salt Manufacturing 

Problem: 

Galvanic corrosion between the tubes and tube sheet resulted in leaking and decreased productivity. 

Galvanic corrosion was caused by the combination of CuNi tubes, mild steel tube sheet, and a brine 

solution. Past repair procedure was to seal leaks by welding. 

Solution: 

Repair surface was sandblasted to a SSPC-SP5 white metal finish. Because Chlorides were present, 

therefore a pressure washing and second sandblasting was required. Complete repair area was then 

chemically cleaned using Cleaner Blend 300. Voids between the tube and tube sheet less than .016” were 

filled using Devcon’s Retaining Compound. All remaining gaps larger in size, were filled using Ceramic 

Repair Putty. Ceramic Repair Putty was allowed to partially cure for 4 hours. Brushable Ceramic White, 

(Food Grade), was mixed and transferred into caulking gun for ease in dispensing. Brushable Ceramic was 

dispensed and brush applied to a thickness of 30 mils. Brushable Ceramic encapsulated the repair areas 

and provided a corrosion resistant, low co-efficient to friction protective surface coating. Devcon’s repair

Lining Victaulic® Elbows 

Flexane® 80 Liquid & Putty 

June 2002 


Mining 

Problem: 

These Victaulic ® brand elbows came from the supplier without a lining. They wear quickly in mining 

applications, such as mineral pulp transport lines, and need a lining to withstand the abrasion. The 

lining available from the OEM is very expensive, more than the original elbow! 

Solution: 

The ends of the elbow were milled 2mm and deburred. The metal substrate was grit blasted and 

cleaned with Cleaner Blend 300, and primed with SA-200 primer. When this was dry, UU-66 primer 

was applied and allowed to dry. The entire interior surface was then coated with Devcon Flexane 80 

putty and liquid.

Coal Diversion Gate Repair 


9/20/91 

Linatex Corporation 

Mining 

Problem: 

These metal gates used to divert minerals for classification would receive extreme abrasive wear. The 

previous method of repair was to attached hardened plate or ceramic tiles to the gates. Attaching 

hardened plate added significant weight and the ceramic tiles would often break due to impact abrasion. 

Solution: 

The complete surface area of the metal gate was sandblasted to a SSPC-SP5 white metal finish. Surface 

area was then chemically cleaned using Cleaner Blend 300. Both FL10 and FL20 Primer were applied to 

the metal gate surface area and each allowed to cure or dry for 15 minutes. Applying both primers will 

improve adhesion of Flexane from 25 pli to 50 pli. Flexane 80 Putty was applied on the metal gate to a 

thickness of 1/8”. Urethane sheets, (.750” thick), were fabricated to cover the metal gates. Urethane sheet 

contact surfaces were roughened and chemically cleaned using Cleaner Blend 300. RU80 Urethane 

Primer was applied to the urethane covers and allowed to cure or dry for 15 minutes. A thin coat of 

Flexane Brushable was applied to the urethane covers to completely wet out the surface. The urethane 

sheets were positioned and compressed into place. Flexane 80 Putty provided a long lasting, flexible 

bond of the urethane sheets to the metal gates.

Bag House Tube Sheet 


Plastic Steel® Putty 

6/33/93 

U.S. Steel Edgar Thompson Plant 


Problem: 

Over months of service the weld seams, and tube sheet joints would wear from processing or filtering 

lime and dry dust particulate. The wear was so severe that air and material leakage occurred. Past repair 

procedure was to weld or reseal with RTV sealant. Both past repair procedures were time consuming and 

offered poor performance. 

Solution: 

Repair areas were first roughened to a SSPC-SP5 white metal finish using a grinding machine. 

Following roughening, all repair areas were chemically cleaned using Cleaner Blend 300. Plastic Steel 

Putty was mixed and applied as a filler to all worn metal areas on both the floor and wall seams. 

Following a partial cure of Plastic Steel Putty, (2 hours), Plastic steel Liquid was applied using a paint 

brush to lock in Plastic Steel Putty and to seal all potential pin holes. This repair process reduced 

downtime by 6 days. The overall cost savings using Devcon’s repair was estimated at $10K.

Concrete Floor Repair 

Floor Patch FC, Flexane ® FC Liquid 

July 2003 

Walt Disney World 

Amusement Park 

Problem: 

Concrete in a heavily traveled area cracking and falling apart due to heavy traffic and wear. 

The expansion joint also needed to be repaired. 

Solution: 

Damaged concrete was chiseled out, squaring the edges for a locked, “feathered edge”. Floor Patch FC 

was used as the area needed to be back in service quickly. Floor Patch FC was mixed/applied into 

area and troweled smoothly. The expansion joint was cleaned out to a minimum ½” depth and FL-20 

Primer was applied in a thin, uniformed coating along the entire expansion joint. This was followed 

using a portable air tank and a 400ml pneumatic applicator, (4:1 ratio) with a Flexane FC liquid 

cartridge, and a 400ml mix nozzle. A uniform self-leveling bead was applied and allowed to level 

until the filled expansion joint was just below the concrete surface for a smooth transition for vehicles 

traveling across this joint.

Customer: Industry: Linkbelt Construction 

Industry: Building Maintenance 

Problem: 

This waste chemical storage room required protection from mild chemicals such as glycol, oils and 

solvents. The storage room floor had not been previously coated and had a number of expansion joint 

cracks. Chemicals could possibly seep through the floor and contaminate the groundwater. 

Solution: 

Complete floor area was acid etched using Devcon’s B-4 Citrus Acid Etch. Once the floor had 

completely dried the floor was vacuum cleaned. All expansion joint cracks were filled using Flexane 80 

Liquid Fast Cure (90 minute functional cure). Flexane 80 Liquid Fast Cure will remain flexible, (350% 

Elongation), and cushion concrete movement due to thermal cycling. Following a 2 hour cure of Flexane 

80 liquid Fast Cure, Concrete Primer was applied to a thickness of 5 mils using a 1/8” nap paint roller. 

Following a partial cure, (4 hours), Epoxy Sealer was applied to a thickness of 12 mils using a 1/8” nap

Rubber Roll Repair 

Flexane ® Belt Repair Kit 

June 2003 

Circle C Equipment 

Agriculture 

Problem: 

Farmers use rubber rolls to flatten hay in order to speed up the drying process of the hay. Occasionally 

rocks will tear apart sections of these rolls reducing their effectiveness to dry the hay. Resurfacing the roll 

with new rubber has an estimated cost of $1,500, besides enormous “downtime” as the farmer must send 

the roll to the shop to be resurfaced. This “do-it-yourself” system would allow the farmer to repair the roll 

the same day. 

Solution: 

Devcon’s Flexane Belt Repair Kit is a complete “do-it-yourself” system that a farmer can repair the rolls 

themselves. All repair areas were sandblasted or abraded using a wire brush. Next, Cleaner Blend 300 

was applied to the metal roll to thoroughly clean all contaminants. FL-10 is used to prime the metal roll 

while FL-20 is used to prime areas that will come in contact with the existing rubber surface. Flexane 80 

Putty is then applied to the roll core building up to the existing roll. Grooves are then made in the Flexane 

80 prior to setting up to match the existing rubber roll. Farmers now repair their rubber rolls in 24 hours! 

Devcon’s repair cost per roll is $100. While sending them out for repair averages $1,500. A major cost 

savings for the farmer.

Concrete Pump Pad Repair 

Floor Patch 

8/4/92 

Laurel Maintenance 


Problem: 

Over several years of service, this pump pad’s concrete would become loose and eroded from a 

combination of vibration and chemical leakage from the pump. The previous method of repair was to 

pour new concrete. Newly poured concrete could not achieve good bond strength and also provided poor 

chemical resistance. 

Solution: 

The concrete surface was sandblasted to remove loose concrete and provide a rough profile. Devcon’s 

Release agent was generously applied to the pump mounting base for easy removal or separation. 

Release agent must be used for easy part or mold separation. Floor Patch was applied onto the worn 

concrete. The pump mounting base was set and leveled on top of the uncured Floor Patch. Fasteners 

were pushed through the the pump mounting base into the uncured Floor Patch. Following a full cure of 

Floor Patch (24 hours), the pump mounting fasteners were tightened.

Fast Cure Rubber Repair Liquid 

8/4/97 

Laurel Maintenance 


Problem: 

The current expansion joints within this floor system received corrosive wear from chemical attack. 

Previous repair method was to fill worn areas with a caulking material. Caulking material offered poor 

chemical resistance to H2S04 and was prone to cracking, ultimately compromising the seal. 

Solution: 

Complete repair area was sandblasted to remove loose concrete and provide a roughened surface. A 

polypropylene backer was stuffed into the expansion joints. The polypropylene backer prevented deep 

migration of Flexane 80 Liquid, reducing the amount required. FL20 Primer was applied to the interior 

of the expansion joint and allowed to cure or dry for 15 minutes. Flexane 80 Liquid fast Cure, (90 

minute functional cure), was injected using Devcon’s Automatic Mixing Application System. Flexane 

80 Liquid’s viscosity allowed the urethane material to self level forming a smooth even flexible, (350% 

elongation), seal.

Products: One Minute Epoxy / Fasmetal / 

Application Date: Flexane® 80 Putty 


Customer: Industry: Alabama Power 

Industry: Utility Power Distribution 

Problem: 

Transformers often develop leaks in a variety of areas such as radiator fins, flanges, circuit breakers, 

valves, and fastener assemblies. The leak on this radiator fin is so severe that oil coolant levels would 

drop, resulting in a catastrophic failure of this transformer. Previous method of repair was to drain 

coolant oil and replace complete radiator assembly. 

Solution: 

One Minute Epoxy is compressed onto the leak area by hand using a polypropylene sheet. (Inserting a 

machine screw to slow the leak prior to applying One Minute Epoxy is advised.) Once the leak has 

stopped, the complete repair area was roughened to aSSPC-SP5 white metal finish using a wire bush. 

Repair area was then chemically cleaned using Cleaner Blend 300. Fasmetal was applied to a thickness 

of 1/8” over the One Minute Epoxy extending 5mm beyond the One Minute Epoxy. Following a partial 

cure of Fasmetal, (1 hour), FL10 and FL20 Primers were applied and each allowed to cure or dry for 15 

minutes. Using both primers will improve adhesion of Flexane 80 Putty from 25 pli to 50 pli. Flexane 80 

Putty was applied to a thickness of 1/2” ,extending beyond the Fasmetal by 2 inches. Flexane 80 Putty 

provided a long lasting, flexible, (350% elongation), final seal that is resistant to vibration and thermal 

cycling. Following full cure, (24 hours), Flexane 80 putty was then painted.

Auger Repair 

Wear Guard Fine Load 300 

January 2004 

Co-Gen II, LLC 

Pulp Paper/Wood Products 

Problem: 

Augers are precise pieces of equipment that needs to be within specification in thickness and height to 

transfer the materials it was intended. The company saw that “hard-facing” the augers saw only a 14 

months life expectancy and thy wanted more! The flights of the auger wear over time from abrasion of 

the material against the flight walls. In this application , the customer “hard-faced” welded one auger and 

coated a similar auger with Devcon’s Wear Guard Fine Load 300 

Both augers went into service for 13 month to determine what method worked the best! As can be seen 

from the photos, the auger with Devcon shows virtually no wear! Measurements taken indicate how 

well the Devcon product has performed over hard-face welding. 

Solution: 

Starting at the drive end the numbers below show the wear of the four flights on the auger,. All numbers 

are in millimeters with nominal flight thickness being 5/8” or 16mm. These numbers show the wear 

over the past thirteen months 

Hard-face welded flights: 14mm 13mm 9mm 10mm 

Devcon coated flights: 22mm 20mm 21mm (22mm is slightly less than 7/8”) 

Devcon’s Wear Guard High Load 300 has proven itself to be superior in extending the life of the auger. 

After determining the remaining wear of the flights the Devcon coated auger would still have 

approximately 12 months of additional service before wearing out. Wear Guard has doubled the life of 

the auger! 

Besides the extended wearing qualities of Wear Guard Fine Load the cost to coat the augers were $1044 

[with 45 minutes labor to coat] compared to hard-facing which was $694/each [with 5-7 hours to coat]. 

The total savings to coat all 12 augurs were $25,000! All new augers will be coated before allowed in 

service with Devcon’s Wear Guard Fine Load 300.

Ball Mill Repair 

Devcon® Irathane® 155 

01/15/02 


Mining 

Problem: 

The customer had purchased a used milling line. The ball mill in the system was very worn on all 

surfaces, including the covers. This was due to defects in the internal coating, which allowed leakage of 

the pulp between liner and shell. The customer needed to restore worn dimensions to original condition, 

and prevent future problems. and used Wear Guard Fine Load on all worn areas. The whole surface was 

then coated with Irathane 155 as protection against possible future liner failure. 

Solution: 

Complete surface was blasted to white metal (SSPC-SP5). Surface was then cleaned with Cleaner Blend 

300. When the surface was dry, eroded areas were repaired with Wear Guard Fine Load. Within 4 hours, 

the substrate was primed with SA-200 applied with airless spray equipment. This was allowed to dry for 3 

hours, when Irathane 155 was applied, using 42:1 ratio airless equipment. Two coats of 155 were applied, 

achieving a total DFT of 2.5 mm. Repairs were made and future damage prevented, using two Devcon
