Product Description:
Tam Tech HF Form Coating is a two component, high performance epoxy coating designed for protecting all types of concrete forms. It greatly extends the life of wood, metal and concrete forms and tremendously improves the concrete finish. 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% solid, self-leveling epoxy that does not require a primer.
Features & Benefits:
- Greatly extends the life of wood, metal and concrete forms
- Tremendously improves the concrete finish
- Hard, durable protective coating
- Bonds to wood, steel, Styrofoam and concrete
- Replaces fiberglass or urethane coatings
- Pourable, self-leveling
- Zero solvents or VOC’s

Instructions:
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. Tam Tech HF Form Coating will not bond to a dirty surface. For best results condition material to room temperature prior to mixing.
Premix part A and part B separately. Then mix at a 4-1 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 or squeegee.
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.
Packaging:
5 gallon kits (5 - 1 gallon cans, 18.9 liters) and 25 gallon kits (5 - 5 gallon pails, 94.6 liters), also available in 55 gallon drums
Cure Time:
Working time is 20 minutes at 74 degrees F. Initial cure is 12 hours at 74 degrees F.
Clean Up:
Clean material before it sets up. Use a solvent like xylene.
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.
High 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)
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 or if ventilation is poor, refer to MSDS for further information. See MSDS for complete information. For industrial use only. Keep out of reach of children. |
