WHAT IS THE SHELF LIFE OF WEATHERSEAL?

We are getting ready to treat our 9-year-old Appalachian Structures Log Home. We used Clear Weatherseal on the initial application and on a follow-up a few years later. Is this still available in Clear? We have a couple of unsealed 5 gallon pails from 5-6 years ago that look to be OK; is there a shelf life problem with this? As we have white chinking, we are apprehensive about using a pre-stained product.

Dear David,

Continental does make WS in clear because is a requested item from ALS. We do not recommend clear because it simply does not provide the protection and longevity of our other stain colors, (no clear coating does, no matter what other companies' claim). The age of WS can be determined by looking at the black stenciled numbers on the lid of the container. The batch number is the 2nd set of numbers below the product code number. In this case, the product code number for clear is 82-0142. The batch code number beneath will start with a letter followed by 2 sets of numbers separated by a dash or slash symbol. The last number of the batch code indicates the year it was made. If it were 5 or 6 that would mean 1995 or 1996, etc. The product may be fine. Check to see if any skin has formed on the top of the liquid. Often a liquid float may be 1/4" or so above the skin so make sure to poke into the liquid to determine if a skin has formed beneath. If a skin is present, cut around the edge of the skin and peel it off and dispose of it. Then mix with a drill mixer. Either scenario, mix thoroughly with a drill mixer till it is thick, pudding like and creamy. It will take 10 minutes or so of good mixing. If it blends together and is homogenous then it is still stable and usable. The only other issue would be length of dry. It may take longer for WS to dry. You should be aware of that. Call me if you are still in need of clarification on any of these matters discussed.
