Appendix D Existing <strong>Epoxy</strong> <strong>Coating</strong> <strong>System</strong> DataPREPARATIONDetergent scrub and rinse with clean water to removesurface dirt, grease, oil and contaminants.Steel Shot Blast (minimum shot size of 330): Use magneticbroom to remove excess shot, sweep to remove large debrisand vacuum to remove fine dust.Scarify: Sweep to remove large debris and vacuum toremove fine dust.Key in all termination points.JOINTS: Cracking of the resurfacer will occur over joints thatare overlayed and later move. Because resurfacers are notflexible, joints that might move should be honored (cut) afterthe installation and filled with an appropriate material.Depending on the preference of the facility owner, joints mayor may not be filled. If the joints are filled, non-moving joints,i.e. contraction or control joints, can be hard filled withthickened, 100% solids epoxy or with a semi-rigid joint fillersuch as Eco-PJS or Eco-EJF. Construction joints lessthan one inch wide may also be filled withEco-PJS. Isolation or expansion joints must be filled with aflexible material designed for this purpose. <strong>Coating</strong> appliedover filled joints will crack if there is concrete movement.APPLICATION - PRIMEREco-PT 250 is applied over Eco-MPE primer that is still wetor sticky--within 4 hours. It is critical that all concrete iscovered to ensure proper adhesion of the overlay. (See Eco-MPE Product Bulletin for application instructions.)NOTE: The kits come with enough Eco-MPE to prime at180-220 sq. ft. per gallon (4.4-5.4 m 2 per litre) for ¼”(6.35 mm) Eco-PT 250 applications. If Eco-PT 250 is beingput down at 3/16" (4.76 mm) and/or the floor is extremelyporous or rough, additional primer will be needed.APPLICATION - OVERLAYCOVERAGE RATE will depend upon thickness. A three bagmix of Eco-PT 250 will nominally cover (finished floor):56 ft 2 (5.2 m 2 ) @ 1/4" (6.35 mm)70 ft 2 (6.5 m 2 ) @ 3/16" (4.76 mm)COLORS: Premix Tennant Colorant before adding toEco-PT 250 to ensure uniform color. Add colorant toEco-PT 250 Part A and mix using a Jiffy® mixer blade andslow speed drill.POUR PART C into the mortar mixer. Begin mixing.ADD PART B (1 qt / (0.95 litres) TO PART A (1.25 gal /4.73 litres). POTLIFE: Mix only enough material which canbe screeded and troweled in a 15 minute period.MIX FOR 1 MINUTE or until thoroughly mixed using theJiffy® mixer blade and slow speed drill.POUR THE MIXED PARTS A&B into the mortar mixer. Mixuntil uniform (approximately one minute). The resin needs toonly wet out the sand.POUR THE MIXED MATERIAL into the screed box. Toachieve a 1/4" (6.35 mm) finished floor, set the screed box at5/16" (7.94 mm). For a 3/16" (4.76 mm) floor, set the screedbox at 1/4" (6.35 mm). If the material is too thick, it will bemore difficult to level.USE HAND TROWELS for edges and touch up.POWER TROWEL MATERIAL to compact and achievefinished texture as soon as possible with an epoxy powertrowel (
Eco-PT Topcoat or Eco-HT Topcoat must also be sanded ifapplying other Tennant urethanes after 24 hours. Use 80 gritpaper except for Eco-HPS, Eco-HPS 100, WearGuard-CRU and WearGuard-CRU 250–use 100. The use ofmore aggressive paper will introduce deep grooves that willnot be covered by a single, thin coat of urethane; swirl markswill be particularly evident if the topcoat is glossy. Werecommend thorough sanding with a swing-type buffer sothat multiple scratch marks cause an obvious gloss loss onall areas (depressions will remain shiny), and the floor isuniformly dulled. The ability to see individual scratch marksis an indication that sanding is not adequate. Scrub withdetergent and rinse with clean water before coating and tackrag to remove fine dust.TECHNICAL SUPPORTFor any preparation or application questions, please callTennant technical support at 800-228-4943 ext. 60751800 226 843 Aust).DISPOSALDispose in accordance with federal, state and localregulations.PLEASE SEE MATERIAL SAFETY DATASHEET (MSDS) FOR SAFETY ANDPRECAUTIONS.USE PRODUCT AS DIRECTED.KEEP OUT OF THE REACH OFCHILDREN.MAINTENANCE GUIDELINESAllow floor coating to cure at least one weekbefore cleaning by mechanical means (e.g.,sweeper, scrubber, disc machine).Care: Proper maintenance will increase the life and helpmaintain the appearance of your new Tennant floor coating.Sweep and scrub your new coating regularly, as dirt and dustare abrasive and can quickly dull the finish, decreasing thelife of your coating. Remove spills quickly as certainchemicals may stain and could possibly permanently damagethe finish.Use soft nylon brushes or white pads on your new floorcoating. Polypropylene or abrasive bristle (Tynex®)brushes can cause premature loss of gloss.Detergent: Tennant has a full range of detergents--generalpurpose to heavy duty--for your cleaning needs. Forassistance in determining which detergent is right for yourfacility or for additional technical information call: 800-553-8033 US (1800 226 843 Aust).Caution: Avoid scratching or gouging the surface. All floorcoatings will scratch if heavy objects are dragged across thesurface.Do not drop heavy or pointed items on the floor as this maycausing chipping or concrete popouts in the case of a weakcap.TORFP GJKZ 09-0063 <strong>SOW</strong> <strong>Attachment</strong> DAppendix D Existing <strong>Epoxy</strong> <strong>Coating</strong> <strong>System</strong> DataRubber tires can permanently stain the floor coating fromplasticizer migration. Plexiglass® between the tire and thefloor coating can prevent discoloration.Rubber burns from quick stops and starts can heat thecoating to its softening temperature, causing permanentmarking.Repair: Repair gouges or scratches or chip outs as soon aspossible to prevent moisture or chemical contamination.CONDITIONS OF SALE AND LIMITATION OFWARRANTY AND LIABILITYThis warranty applies to all Specialty Surface <strong>Coating</strong>s, withthe following exceptions: Eco-Hard-N-Seal,Eco-EDP (Electrostatic Dissipative Primer),Eco-EDE (Electrostatic Dissipative <strong>Epoxy</strong>), and SDS(Static Dissipative <strong>System</strong>).
