Check Mate 2: Check Filler/Sealer

Canadian Log Home Supply


Check Mate 2
Check Filler/Sealer

Check Mate 2 is an outstanding water resistant sealant that prevents water and air infiltration through pronounced cracks (called checks) in logs, timbers and wood siding. Caulking is an obvious solution to this problem, but caulking does not work because of limits in adhesion and weather-ability.

As a check filler, Check Mate 2 forms a tough elastic filler and coating. It has superb colour stability and resists ultraviolet rays, ozone, mold, mildew and airborne contaminates. Even the most troublesome leaks can be sealed with Check Mate 2.

It is especially important to seal upward facing checks in any location where they may accumulate water. If these checks are left unsealed, they become sites where rot may begin to take hold. If you have old checks where rot is a risk, be sure to apply Shell-Guard before sealing with Check Mate 2.

Check Mate 2 available in most colours to match Lifeline exterior stains.
