Installation

General Instructions
See separate doweling, laminating, and patching instructions for more specific instructions. CSI format specifications are available.

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 Gripstone which can be used in 10 minutes. Avoid stressing joint before complete cure of Gripstone. Mask areas which must be kept free of Gripstone. 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: two parts hardener to 98 parts Gripstone. 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 50 mils (1/16th of an inch). 231 cubic inches per gallon when mixed at 50 mils (1/16th of an inche). 231 cubic inches per gallon.
