General Instructions
Surface Preparation
and Use
Use gloves, wear eye protection, and avoid skin contact. When grinding
cured patches or non-structural joints, wear a dust mask. Substrates
must be completely dry and dust-free. Mix only the amount of Polyester
which can be used in 10 minutes. Avoid stressing joint before complete
cure of Polyester. Mask areas which must be kept free of Polyester. Clean
tools with toluene or xylene. (Use caution, these solvents are flammable.
Ensure local ventilation.)
Mixing instructions:
All materials should be at or above 45°F. Combine the two ingredients
at the following weight ratio: three parts hardener to 100 parts
Polyester. Mix thoroughly.
Prepare only as much material as can be immediately used.
Temperature dependency:
Temperature will affect the working properties of the material. Approximately
every 10°F results in doubling the speed of cure. Therefore, at 85°F set
time is cut in half, at 65°F the set time is doubled.
Coverage:
Approximately
30 square feet per gallon when applied at thickness of 50 mils (1/16th
of an inch).
Availability
Packaging and Storage
Touchstone Flowing Polyester is available in quarts and gallons. Polyester
has a shelf life of six months at 70°F in unopened containers. Under
no circumstances should the hardener be allowed to get above 100°F.
