Chinking & Log Caulking FAQ's

What is the difference between chinking and caulking?
Log chinking is an elastic sealing material that has a coarse surface which is designed to look like old-fashioned mortar and is typically used on larger joints. Log home caulking is a highly elastic sealing material that has no surface texture and is mainly used in smaller joints.

Should I chink or stain my log home first?
It is best to apply a stain that is compatible with the chinking first. The stain acts as a primer for the chinking and normally improves the overall adhesion of the chinking material. Additionally, it makes the clean up process for the chinking material much easier.

What type of tool should I use in order to apply my chinking or caulking material?
Most applicators use foam brushes. Others use steel or plastic trowels.

Do I need to chink or caulk my log home?
At some point you will probably need to caulk or chink your log home.  You can not stop logs from moving.

What do I do to my chink when it’s time to re-stain?
It is difficult to keep maintenance coats of stain off the existing chinking material. The stain can be brushed on by hand in an attempt to keep it off the chinking, but this can be very time consuming. Another option is to spray over top of the chinking material and then come back over the existing chinking material with a product called Brushover. This product is a textured, elastomeric coating that is available in the same colors as Log Jam chinking. Simply paint over the chink line to restore the original color of the chinking.

Can I stain overtop of the chinking and caulking on my home?
Yes. All Weatherall stains will wet-out and adhere to most chinking and caulking products.

Do I need to maintain my chinking material?
No. If the chinking material is properly installed, there should be very little maintenance work down the road.

How do I fix my chinking or caulking if it is torn?
The entire process is rather easy. Begin with a clean surface. Gun the new chinking material over the torn area, and tool the new chinking material onto the old chinking material. The old and new chinking material should bond together.

Note: This situation usually occurs because of an improper application or because a few large logs have settled.
