Conceal Chinking FAQs

Can I apply Conceal before I stain to get a better match?
Possibly. It is best to apply the closest color Conceal after all staining is complete, so long as you’re using a compatible stain. Because most stains are relatively rigid, when they’re applied over a flexible material like Conceal, the stain will crack (unlike the sealants) when the logs move like we know they do, and the underlying sealant will show through.

Can I chink with Conceal?
Yes, if the chink line is smaller than 1 1/2" wide. Anything with a wider width should be filled with Chinker’s Edge or Log Jam.

Can I use Conceal on the interior of my home?
Yes! Be sure to follow all proper application instructions as outlined in the Conceal Data Tech.

Can I use Log Builder or Conceal around gutters?
In general, no. Water-based products should not be used in areas that may experience large volumes of water.

Can I use Log Builder or Conceal on a joint over 2 inches?
In general, no. Log Jam or Chinker's Edge would be better choices for gaps this wide. Log Builder and Conceal both work well on joints that range from 1/4" to 2" wide.

How should I tool Log Builder and Conceal?
The best way for many people is with a damp foam-wedge brush. Others prefer shaped metal trowels or any curved tool to push the caulking into the joint. You do need to tool the bead, even if you’ve laid it down very neatly. Tooling pushes the bead of caulking into contact with the wood, insuring great adhesion!

What is the difference between Log builder and Conceal?
Conceal is lightly textured and diffuses light, so the caulk “disappears”. Log Builder has no texture and gives a more shiny finish when dry.

Will Log Builder or Conceal stick to stone and masonry where my fireplace attaches to my logs? Will it work where my aluminum flashing meets logs or metal roof meets logs?
Yes, both will adhere very well to such stone and masonry. Your main concern should be that if the stone or masonry is made hot by the fireplace, then the sealant will likely not survive such high temperatures. Be sure to read the Data Tech for specific temperature ranges to ensure the product will work for you.
