Log Check Sealant

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 weatherability.

As a check filler, Check Mate 2 forms a tough elastic filler and coating. It has superb color 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.

five star Annette on 11/11/2016 - "I found this product while looking on your website and realized I needed to fill in some of the larger cracks in my logs. This product was easy to use along with the backer rod that we also purchased. Dark Brown is the color we used. We love your products!"

five star Roz on 11/3/2016 - "Very good product! We used it to seal up several small checks in our logs and boards. I would recommend the clear colored Check Mate because it will go with any stain color. We watched the video on the website about Check Mate 2 application, so I would recommend seeing that if you have a chance."

four star Lauren on 9/15/2016 - "I think this is a great caulking product! We ordered the Check Mate 2 kit in Medium Brown and used it to fill in a few large checks on my log home. It also works well to seal gaps and cracks in other places around our home. The only thing I would note is that you may want to purchase Clear or make sure the color is close to the stain color because it does not really take much stain over it. Love this product otherwise!"

five star BJ on 3/25/2016 - "We used Check Mate 2 to seal our checks about a year ago and it's performing perfectly. Our checks are all still sealed tight. It looks like it's going to pass the test of time! The video on the website really helped with application."

four half star L Bloom in CO (07/15/14) - "We just love Check-mate 2. This is the product recommended to us by the folks at Perma-Chink in Rifle for the cracks in our logs. We chose the clear and it just perfectly sealed the crack and blended into the wall. You can't see the caulking, but the crack is sealed and the wall is beautiful. Thanks for the great advice!"

two star T Illingworth in TN (05/25/2014) - "I wish you had more color choices of Check Mate 2… "

two star J Friesenhengst in WB (07/02/2013) - "Thank you for recommending the Check Mate 2. It is holding up great with the movement of the checks. I just wish the colors would match your stains better like the Energy Seal does. Check Mate 2 takes a stain but not like the Energy Seal."

three star R Blacksten in WI (04/14/2011) - "Thank you for all your help. I realize after the Web-training that I was using the wrong product in my checks. The Check Mate 2 is preforming much better than the Energy Seal I just wish you had better colors."
