Log siding presents much more of a sealing challenge than stacked logs for several reasons. As stacked logs season and shrink, they settle on top of each other. If there are sealed gaps between the logs, the width of the gaps between the logs may remain fairly uniform as the logs settle. On the other hand, log siding is nailed or screwed into dimensional lumber which holds the siding in place. As shrinkage occurs, the gaps between the courses can become wider and wider (see pictures below). In addition, if the siding is not properly attached to the wall, it can twist and warp, creating even larger gaps between the courses.


“Which of your products should I use to seal my log home?” is a question often put to us by prospective customers. Why do so many people refer to “sealing” a log home rather than staining or finishing? Nobody talks about sealing siding or trim on a stick built home. They are either stained or painted, yet sealing is the term used by many log home owners. As it relates to log homes the term “sealing” dates back to the early 1900s. Prior to then, most log homes were constructed using heartwood from old growth timber and left bare.

As hot weather approaches, we begin receiving calls about resin bleeding out of logs, and what can be done to stop it. Some people call it sap, or pitch, or resin, but it’s all the same, and short of replacing the log or logs that are bleeding, there is nothing anyone can do to stop it from occurring.

Do you need to remove any caulk that’s already in place before applying Energy Seal™, Woodsman™, or Check Mate 2®? Applying new sealant over old caulking is never a good idea, even if it looks like the old caulk is still sticking to the wood. The old caulk should be removed for several reasons.

All of our stains and sealants are water-based, and while they are still wet, most clean up quite easily with just soap and water. That’s usually the best method to use for cleaning our wet, uncured products off of windows, gutters, downspouts, and other smooth surfaces, but there are occasions when other clean-up techniques should be used to remove some of our textured sealants from wood surfaces.

Mold and mildew (actually another name for mold) are colonies of living organisms that can grow on the surface of many materials, including wood. Their color may range from white to black, with just about every color in between. If the discoloration is green, it’s probably algae, a plant, since molds and mildews do not contain green chlorophyll.

Although paint primers have been used for many years, clear primers for wood are few and far between. Prelude™ is the only water-based clear primer on the market that’s specifically designed for use on log homes before the application of a water-based transparent stain.

Centipedes, millipedes, pill bugs, roaches, crickets, ants, beetles, spiders, wasps, squirrels, opossums, raccoons, bats and mice are just some of the pests that manage to find their way into homes. It’s just about impossible to keep all of them from getting in, but there are several things that you can do to significantly reduce the number of pests that make it inside your home. Most have to do with blocking the ways they can enter. Furthermore, there are also some things you can do outside to make your home less attractive to pest invaders.

While we call our pigmented finishes “stains,” in reality they behave more like water-based paints than traditional oil-based stains. The word stain itself implies that the wood fibers become “stained” with the pigments contained in the product, whereas water-based finishes form a film that covers the wood fibers without actually coloring or “staining” them.

Every summer we receive calls about small flying insects making holes in the exterior surfaces of logs. They are usually described as tiny flies, bees or flying ants, but in fact these insects are small parasitic wasps that are about the size of a fruit fly or large gnat. There are literally hundreds of parasitic wasp species and some of them specialize in parasitizing beetle larvae including wood boring beetles. They can be seen going in and out of existing beetle emergence holes looking for live beetle larvae to lay their eggs on.
