Fire Protection Steel Spray CFP-S WB Application Instructions (continued) Interruption of work and clean up procedure ■■ Hilti Fire Protection Steel Spray can remain in the hose for up to 1 hour. ■■ When interrupting work for longer than one hour and at the end of the day a thorough clean up procedure must be followed to prevent material from curing in the tip and spray gun. Make sure a pail of clean water is readily available. 1. Turn off power 2. Turn down pump pressure 3. Remove spray tip and spray housing 4. Place spray tip and housing inside pail of clean water 5. Replace Hilti Spray pail with a pail of clean water and slowly dispense all material contained in the hose into Hilti Spray pail. Once water starts flowing from spray gun, release trigger to avoid diluting the original Hilti Spray. 6. Turn down pump pressure 7. Place spray gun into pail of clean water and flush system for approximately 5 minutes to wash all fibers from spray gun and hose line. 8. Roll up pump hose 9. Leave spray gun, tip and housing into pail of water. 10. Place a plastic liner on top of the remaining Hilti Spray and replace pail lid to avoid product from curing in the pail. Final measurements and top coat application ■■ Once all required coats have been applied and fully cured, a simple measurement of mill thickness can be done utilizing a dry film thickness gauge. In most projects this is mandatory and is often performed by third party inspection firms. The DFT reading should be taken as soon as the coating is sufficiently hard to avoid indenting the surface. Dry film thicknesses (DFT) may be measured using a permanent magnetic type banana gauge or an electronic electromagnetic type gauge. These measurements should be taken on a daily basis and a record kept until a constant DFT reading is achieved ■■ The DFT of Hilti Fire Protection Steel Spray can be calculated from the total DFT by subtracting the primer DFT ■■ Only after the Hilti Fire Protection Steel Spray is fully cured, according to specifications and site conditions, a Hilti approved topcoat can be applied. Typical curing time before a top coat is applied varies between three and five days. A top coat is not required on interior applications. If desired, the following tested and approved top coats may be applied for decorative purposes: • Glidden Evermore: Premium Exterior Latex Semi-Gloss GL68XX • Benjamin Moore Moorglo Soft Gloss Fortified Acrylic House Paint • Sherwin Williams: Sherwin Williams Steel Master 9500 30%Silicone Alkyd. Material storage and shelf life ■■ Hilti Fire Protection Steel Spray must be stored in the original unopened pail. It must be protected from water and direct sunlight and maintained at a temperature between 41°F (5°C) and 104°F (40°C) during shipping and storage. The product must not be stored at freezing temperatures. ■■ When stored properly, Hilti Fire Protection Steel Spray has a shelf life of 12 months from the date of manufacture. See product label for expiration date. Primer additional information ■■ All structural steel to be coated with Hilti Fire Protection Steel Spray must be primed with an approved primer. The primer must be applied in full compliance with the manufacturer’s recommendations, and must be fully cured. ■■ Approved primers are generally of the phenolic resin modified alkyd type. Organic and inorganic zinc silicate primers are not suitable for use with Hilti Fire Protection Steel Spray. Please contact Hilti Technical service department for confirmation of primer compatibility. Other specifications ■■ Maximum wet film thickness (WFT): per pass at 68°F and 50% relative humidity • Utilizing spray: 63 mil • Utilizing brush: 30 mil ■ ■ Number of coats: For airless spraying, several thinner coats of 20 mil as opposed to one heavy coat of 40 mil (1.0 mm) allow the sprayer greater control over thickness and finish, and reduce the drying time. ■ ■ Drying time: The drying time is dependent on the wet film thickness, temperature, air movement, and relative humidity. A coat of 16 mil (0.4 mm) WFT takes approx. 6 hours at 68°F (20°C) and 50% relative humidity to dry. It may be possible to apply two coats in one day if the air temperature is above 68°F (20°C), there is good air movement and the relative humidity is between 30% and 50%. Brush or roller application increases drying time by approximately 20%. 8 Hilti, Inc.
