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.

Osborn Brushes are excellent tools to help prepare a surface before the first coat of finish is applied. They consist of nylon bristles impregnated with particles of silicon carbide which act as an abrasive. Osborn brushes are surface conditioning brushes, not sanding brushes. So what is the difference? Sandpaper and sanding disks are designed to remove the top layer of wood, whereas Osborn Brushes are designed to smooth the surface of the wood without removing the entire top layer.

Following are some comparison points of Lifeline™ finish systems to typical oil-based products.

Environmental Issues

Most oil-based finishes contain some type of organic solvents that evaporate into the air when they dry. These components are known as Volatile Organic Compounds (VOCs). When VOCs are in the vapor state and interact with NOx (Nitrogen Oxides) in the presence of ultraviolet (UV) light, ground level ozone or smog, a health hazard to humans, forms.

How To Prevent Mold And Mildew

Learning about Mold and Mildew

Mold and mildew are terms that are used interchangeably since they refer to the same living micro-organisms. For simplicity we’ll refer to them as molds. Molds encompass a wide range of fungal species that can live on the surface most materials, including wood. They require air, water, and food. Their color is usually white or black, but can be just about any color. If the growth is green, it’s probably a plant-like organism called algae.

One of the best tools an applicator or homeowner can have in their possession is a moisture meter. In addition to finding trouble spots due to water infiltration, it can also help determine if the surface of logs are dry enough to seal or finish.

Moisture content of logs can dramatically affect the application of some of Perma-Chink Systems' products. We recommend that moisture content is below 35% for maximum adhesion of our finishes.

Although there is not much difference in the formulation between Lifeline Advance™ Satin and Advance Gloss, Advance Satin contains a flatting agent for the purpose of reducing its reflectivity, or "gloss." This raw material can settle to the bottom of the container over time.

"Stir well before use" 

This term, or its equivalent, appears on every container of stain and finish we sell. It is there for a good reason - most of our finishes are formulated with low viscosities, making them easy to apply with an airless sprayer and in thin layers. Any pigments they contain are heavier than the liquids, so over time they may settle to the bottom of the pail.

If the container is not stirred thoroughly and the pigments are not uniformly distributed throughout the product, the color may change as the stain is applied. This situation is easy to avoid with proper mixing both before use and occasionally during use.

Which is the best way to remove an existing finish, media blasting or chemical stripping? Like most questions of this nature there is no definitive answer, it depends on the situation. Both methods of removing a finish have their positive and negative attributes. The results will depend on the competence of the person or persons doing the work as well as the method used. For the sake of comparison, we will look at the features of each method to help you make a more informed decision about which one to choose.

Perma-Chink Systems sells two epoxy products, M-Balm®, a wood consolidator that hardens loose, friable wood fibers, and E-Wood®, a putty used to fill voids or cavities in logs and timbers. Both M-Balm and E-Wood are two component epoxies. Like all epoxy products, they consist of a resin and a hardener and rely on a chemical reaction between the two components to become hard. As they react they often become warm, or even hot. M-Balm, in particular, can become quite hot about 15 to 20 minutes after the two components are mixed together.
