What is WOODguard?

WOODguard is a one coat, oil based EPA registered wood preservative, designed for exterior log homes and siding. This product contains titanium dioxide which reduces damage from the sun’s ultraviolet rays. It is available in 6 pre-tint colors and 14 Blairstown Distributor additional colors.

How much WOODguard will I need?

On initial applications one gallon of WOODguard will cover approximately 150 square feet of re-sawn cedar siding or about 200 square feet of logs. To use a rough calculation, multiply the length times the height of the home times 1.4 (Area = Length X Height X 1.4). The 0.4 takes into account windows and doors. Always apply as much WOODguard as can be absorbed by the wood. Only one coat is required. However, that one coat must be applied to the point of refusal.

When is a good time to apply WOODguard?

The best time to apply WOODguard is when the minimum night-time temperature is 50°F or higher. Do not apply during or right after a rain. The wood surface must be dry before you initiate application.

Is WOODguard VOC compliant?

WOODguard is VOC compliant and meets all current state and federal air quality requirements. The active ingredient, copper 8 quinolinolate is suitable for use on wood that may have incidental food contact. 

How does WOODguard work?

WOODguard’s oil formula penetrates deeply into the wood structure, coating the wood cells where it molecularly bonds into the wood. WOODguard cures in a liquid state and remains flexible. WOODguard will not harden or crack through wide temperature and moisture extremes.

What type of caulk should I use with WOODguard?

An oil based (polyurethane) caulk is usually best; caulking is generally done before applying WOODguard. Always caulk on clean, dry surfaces, the more caulk in contact with a substrate the greater the adhesion. Caulk around windows and doors and in corners where logs are scribed to fit. When using WOODguard, unlike other products it is normally not necessary to caulk cracks and checks within the log.
Consult our customer service department for specific recommendations. 

Can I use WOODguard on the interior of my log home?

We recommend WOODguard ITF for this purpose. 

The WOODguard on my house went on VERY dark. It is way darker than the color shown in pictures and on the website. What's wrong?

Nothing is wrong! WOODguard goes on VERY dark and lightens considerably during the cure period. If your WOODguard is NOT DARK upon initial application, this is an indication that you are not applying it to the point of refusal and are not getting a proper treatment.

Where can I find WOODguard?

Blairstown Distributors, Inc., is the largest and oldest distributorship in the country. Blairstown Distributors has been selling WOODguard and helping its customers for over 25 years. Our years worth of knowledge is absolutely vital to customers for preparation & application of this product.

Is WOODguard easy to use?

WOODguard is easy to apply via brush, coarse spray or roller. A garden pump-up sprayer is recommended and back brushed to an even coat. Just apply to the point of refusal. WOODguard does its job with just one initial coat. WOODguard cleans up easily with mineral spirits. (Do not apply with an airless sprayer.)

How do I prepare the wood surface of an application of WOODguard?

Before applying WOODguard, ensure the surface is clean and that the wood is dry. Although many people suggest power washing with one quart of bleach and three quarts of water with 4 oz. of Tri-Sodium Phosphate (TSP), too much bleach will bleach out the natural color of the wood. Other products are available that are less intrusive on wood than bleach.

What are the benefits of using WOODguard?

WOODguard protects against cupping, curling and warping. WOODguard controls fungus, wood decay, mold, mildew, termites and anabiid beetles with its EPA registered wood preservative Copper-8-Quin
olinolate. WOODguard penetrates deep and cures below the wood surface to enhance the natural beauty of wood. WOODguard reduces the damaging by the sun’s rays (UV) and preserves the natural beauty of the log finish for years.

How is WOODguard rated?

An independent study of the log home industry concluded that WOODguard is the exterior wood preservative and stain most recommended to consumers by builder/dealers nationwide. The survey also revealed that more log home models were treated with WOODguard than any other product during their previous application.

My house has 3,000 square feet of exterior surface area to treat. My contractor applied 7 gallons of WOODguard. Three months later it looks like it's gone. What's wrong?

Way too little WOODguard was applied. Always apply WOODguard to the point of refusal. If you can’t get new wood to accept at least a gallon of product for each 175 square foot area, suspect a mill glaze problem.

When should I add additional mildewcide to my WOODguard? What kind is recommended?

If the exposure conditions are going to be very hot and humid or otherwise adverse, additional mildewcide can be added to provide extended mildew control. WOODguard cannot prevent the reoccurrence of mold and mildew on extremely dirty surfaces or inadequately ventilated areas. If you decide to add mildewcide, we recommend M-1 which contains 3-lodo-2 propynl butyl carbamate, better known as IBPC.
