High Performance Epoxy Coating For Protecting Concrete Forms

Tam Tech HF Form Coating is a high performance special epoxy coating that dramatically extends the life of wood, steel and concrete forms without having to replace or resurface them. It also tremendously improves the appearance of the concrete finish with easy clean-up between castings. Tam Tech HF Form Coating is ideal for pre-cast and cast-in-place applications providing a hard, durable surface to protect the forms. It is a 100% solids, special proprietary epoxy that requires no primer. A faster-setting version is available for cool weather applications. It also comes in different colors including clear, gray, etc.

Form Coating Product Features:

• Greatly extends the life of wood, steel and concrete forms
• Tremendously improves the concrete finish
• Easy clean-up between castings
• Hard, durable protective coating
• Bonds to damp surfaces
• A fast setting, low temperature formula is available
• Available in clear, gray plus ten other colors
• Zero solvents or VOC’s

Form Coating – Instructions for Use:

The form surfaces should be clean and sound. Remove all concrete residue, dirt, oil, grease, and other loose materials. A light sanding of the forms will increase bond. Surfaces can be cleaned with a solvent wipe or an application of warm water with a detergent followed by a warm water rinse. Continue cleaning until water will no longer bead up on the forms. Remove all standing water. Then clean with a vacuum or oil-free compressed air. Let dry. For best results condition material to room temperature prior to mixing.Premix part A and part B separately. Then mix at a 2-1 ratio for three minutes in a third container with a low speed drill (about 600 rpm) and a jiffy mixer. Do not use high speed mixing, it will whip air into the material. The mixed material should be uniform in color. Mix only what can used within the working time of 20-25 minutes at 74 degrees. Then immediately apply the material onto the forms with a short nap epoxy roller, trowel, brush, squeegee or grooved fiberglass roller. Do not excessively roll the coating.Recommended application thickness is 15 mils. One gallon of material will cover about 120 square feet per gallon at 15 mils of thickness depending upon the surface texture. Then after initial cure, apply form release to coating before pouring concrete.

Form Coating Limitations:
Store product above 40 degrees F (5 degrees C). Substrate and air temperature must be above 50 degrees F (10 degrees C) during application and during curing. Check the relative humidity and the dew point. The surface temperature should be 6 degrees above the dew point. Hot temperatures will accelerate the set time and cold temperatures will slow down the set time.

Shelf Life & Storage Temperature:
One year in unopened containers at 40 to 90 degrees F (5 to 32 degrees C).

Coverage:
One gallon of material will cover about 120 square feet per gallon at 15 mils of thickness depending upon the surface texture. This is an estimate only. Some customers apply at a heavier rate of application.

Clean Up:
Clean material before it sets up. Use a solvent like xylene.

Packaging:
3 gallon kits (11.3 liters)  (2 gallons of part A, 1 gallon of Part B) ;15 gallon kits (56.6 liters)  (2 – 5 gallon pails of Part A, 1 – 5 gallon pail of Part B)Also available in 55 gallon drums. NOTE: Shipping may be adjusted after location verification due to UPS size and weight restrictions.

Cure Time:
Working time is 20 minutes at 74 degrees F. (23 degrees C) Initial cure is 12 hours at 74 degrees F.

Warning:
Skin contact may cause irritation, redness or burns. Remove clothing if contaminated and wash skin thoroughly with soap and water. For eye contact, flush with water for 15 minutes and call a physician. It is a strong sensitizer so avoid breathing vapors and ingestion. Use safety glasses and wear chemical resistant gloves. Use with adequate ventilation / forced local exhaust or if ventilation is poor, refer to SDS for further information. NIOSH approved, organic vapor respirators and forced exhaust are recommended in confined areas. Do not weld on, burn or torch the epoxy material. See SDS for complete information. For industrial use only. Keep out of reach of children.
