Pot Life
For a 1 kg. unit mix at 70 F, pot life is approximately 30 minutes. Higher temperatures or larger mass will shorten this time, lower temperatures or smaller mass will extend it. Pot life can also be extended by spreading the mass out to dissipate heat.
Color Gray
Storage Store in dry area in closed containers between 50 F and 110 F. Shelf life at these conditions is greater than one year.
Coverage
EXP THIXSET is a trowel-on rebuilding compound that can be applied up to 1/4 inch without slumping. Thicker applications can be achieved by multiple layers. Theoretical coverage at 40 mils is 36 cubic inches per kg.
Surface Preparation
  • For maximum adhesion, material should be applied to a firm, clean, dry and abraded surface.
  • Best results will be obtained by abrasive blasting the surface.
  • If blasting is impractical, a grinding wheel, needle gun, or very stiff wire brush may be used.
  • Clean greasy, oily or waxed surfaces with suitable solvent before applying material.
Mixing & Application
Mixing
Mix ALL of Part A with ALL of Part B. Mixing may be done in a container large enough to hold both the base and hardener. The selected container must be clean and dry. Mix the material thoroughly until no streaks of any kind are visible. If materials are cold, warm them to 70 F before mixing.

Cleanup
All mixing and applications tools should be immediately wiped or scraped clean when finished with using.

Application
EXP THIXSET is best applied with a squeegee, trowel or the plastic applicator supplied with the kit. Press material thoroughly into substrate and insure a completely wetted out surface. Build up to the required thickness with a second pass. Large cracks or holes should be bridged with glass or metal cloth.

For best results, do not apply:

  • When temperature is below 50 F
  • When humidity is over 90%
  • When there is moisture on the surface
  • When surface temperature is not 5 F above dew point
Force Curing
Force cures are recommended for severe service conditions as both the physical and chemical properties are enhanced. Force curing should not start until material has firmly set.

Recommended Force Cure Schedule:

  • 1 hour at 250 F
  • 4 hours at 180 F
  • 8 hours at 140 F
