How WOODguard works:
Copper 8-quinolinolate is WOODguard’s active ingredient (0.675%). It is effective against mold, decay, termites and anobiid powder post beetles. Since it doesn’t break down when exposed to sunlight, Copper 8 provides longterm protection for your wood. Due to this active ingredient, the Environmental Protection Agency (EPA) registered WOODguard as both a wood preservative and a pesticidal product.
Titanium dioxide (TiO2), Zinc Oxide and “trans iron oxides”
These UV blockers protect wood against the damaging effects of sunlight and improve water repellency. Tinted WOODguard provides even greater UV protection than clear WOODguard due to the pigments in it. (The darker the pigmentation, the greater the UV protection).
WOODguard’s oil formula naturally repels water, preventing long term damage like mildew and rot. It penetrates deeply into the wood, conditioning it to prevent cupping and warping. Even though it keeps water out, the oil allows the wood to breathe freely so that moisture can escape.
Most importantly, the oil formula never dries or forms a film on the surface of the wood. This means that when wood expands and contracts, WOODguard can never crack or peel like film-forming stains eventually do.
A “Green” Preservative:
WOODguard is one of the few green wood preservative products on the market. With only 94-108 g/L of Volatile Organic Compounds, it meets the VOC standard levels set by the Ozone Transport Commission (OTC) and the even more stringent limits set by the state of California. It meets the VOC requirements and is available in all 50 states.
How to Apply WOODguard:
Watch this video for the manufacturer’s tips on how to best prepare your wood and apply your WOODguard stain. Or keep reading below!
1. Preparing your Wood:
Why it’s important
Whether your wood is new or weathered, you should wash it thoroughly before applying WOODguard to remove any mill glaze, dirt or mildew. Cleaning the wood in-between applications also keeps it from darkening as quickly over time.
If your wood was previously treated with a different product, make sure to order a sample pack of WOODguard or you can even try some motor oil on your wood to test whether WOODguard will be able to soak into it.
How to clean your wood
- Mix 1 gallon water with 1 quart liquid bleach and 8 oz Trisodium Phosphate. (TSP is a cleaner and degreaser that you can find at a local hardware or paint store.)
- Pour this mixture into a pump-up garden sprayer.
- In small, manageable sections, wet the wood with water.
- Spray generously with the TSP solution, working from the bottom up. If needed, scrub the area with a stiff bristled nylon brush, keeping the surface wet. Important: Don’t allow the solution to dry on the wood!
- Rinse the solution off of the wood from the top down, using a power washer set to below 500 psi. You should hold the power washer nozzle about a foot away from the wood.
- Make sure you’ve completely rinsed away all the bleach. You can check the rinse water with PH paper to ensure that the PH from the runoff water is the same as from the fresh water.
After you’re done
Allow the wood to dry completely before applying WOODguard (less than 18% moisture). The drying time will vary depending on the weather, but even in warm sunny conditions allow at least two days for the wood to dry. If the brush left any fuzz on the wood, give it a quick sanding with coarse-grit sandpaper.
2. Mixing your Stain:
Before you apply WOODguard Exterior, mix it thoroughly so that the color goes on evenly and no ingredients are left at the bottom of the container. If you need to use buckets from different batches, you can mix them together to make sure the color is consistent.
IMPORTANT: Remember to keep the stain mixed, as the colorant will settle out quickly. You should be mixing the container whenever you take out more stain.
For single gallons
These can be easily mixed with a paint stirrer. If you ordered any additives such as Bee Gone, NBS 30 or MX-3, don’t forget to measure out the appropriate quantities and add them to your stain before stirring.
For 5-gallon buckets
Our custom colors are shipped as a quart of colorant that comes with a 5-gallon bucket of clear WOODguard. You should pour the entire quart into the bucket before mixing it up. If you ordered any additives such as Bee Gone, NBS 30 or MX-3, now is also the time to add the entire bottle(s) to your stain.
Unfortunately the bucket lid doesn’t come off easily. So we recommend leaving the lid on and using a drill mixer like the Hyde Stir Whip to mix through the bunghole. The mixer attaches to an electric drill and should reach all the way to the bottom of your bucket.
If you don’t have a mixer, another option is to transfer the stain into another 5-gallon bucket that comes with a lid. You can use a small amount of Mineral Spirits or Paint Thinner to retrieve any ingredients left in the bottom of the original bucket and add it back into the new bucket.
And again, don’t forget to keep mixing up your stain frequently as you apply it.
3. Applying your stain:
Wait for the right conditions
You’ve cleaned your wood, allowed it to dry, and mixed up your stain. But before you start, check your weather forecast. For best results, apply WOODguard when no rain is expected for at least 24 hours, the overnight low temperature is above 50°F/10°C and the daytime high temperature is below 95°F/35°C.
What to use
You can use a regular paint brush or roller, but the fastest way to apply WOODguard is with a backpack pump-up sprayer. Do not use an airless paint sprayer. This is because airless sprayers use high pressures that will atomize the WOODguard and make it harder to contain. Atomized WOODguard is dangerous to plants and should not be breathed.
-Spray on a single coat to the point of refusal. Don’t be afraid to apply the WOODguard very heavily; it has no drying agents so it will not leave lap marks or runs after it has been fully absorbed. The more stain the wood absorbs, the longer the treatment will last and the better it will protect your wood.
-After spraying, back-brush with a good quality brush in the direction of the grain.
WOODguard only needs one coat. Although WOODguard can be rained on after 24 hours, it will take 3 days to 2 weeks to cure completely and will usually lighten considerably during the curing period.
You should re-stain your wood about 2 to 4 years after the initial treatment. After that, reapply only as needed. Walls that are more heavily exposed to sun may need a new coat before the rest of the house does.

What brand of caulking should I use to fill the small gaps between the logs1-1
Which caulking sealant is most compatible with WOODguard?10
Does color need to be added to woodguard for UV protection, or is all protection in the base 5 gallon bucket. Our log blasting turned out darker than we expected, so we’d like to go with a clear treatment if it is still going to be protected as if we added the tint.00
I have a cedar pergola that I would just like to put a clear coating to prevent UV and other damage. Would WOODguard work in this application? And does the clear stain have a Sheen?00
I bought a sample pack last year and decided to go with the dark walnut. Unfortunately it is not dark enough. I was wondering if you have any sample packs with the darker stains like sienna?00
Does the oil component contain linseed oil?00
Do you still have WOODgaurd Honey Gold stain color available?00
What is the shelf life of unopened Woodguard stain?00
I have used Honey 2000 on my log siding since 2007. I see Amber honey is now available. It this just a shade darker than honey 2000 ?00
I plan on building my own log home soon. Can you apply this solution on freshly cut non-seasoned logs or must I wait until logs moister percentage is at a certain point? Please advice…00
Why do you not recommend using an airless sprayer to apply Woodguard?00
We live in LA and would like to stain our cypress exterior doors with this semi-transparent. Can we use this to stain the whole door…inside and out?00

We had our cedar log home built in 1986. We used the same product on it until 2014 when we decided to switch to Woodguard honey 2000. We are very impressed by this product! There was only light prep work needed before we stained it again 7 years later. This is a great product!!

Product has been on logs since 2005. In process of cleaning and pressure washing house. About 2 gallons in a 5 gal. pail, no color on pail. I called customer service, wondering how to figure out color. By giving my zip code, she was able to look up purchase by original builder. Two owners in between him and us. She confirmed the address, name of purchaser and the color of the stain. Awesome customer service. I have used two different products on a cedar log cabin, and this appears to last better than those. Looking forward to putting a new coat on these logs (pine). Again, awesome customer service. Ordered more of correct color.
I used this on a customers house and I will never use anything else again, best product out there!

I used this on our cabin built in 1990 which had been neglected. Not only does it leave a perfect finish on our Rough hewn log home, but it clearly nourishes those areas of the longs that are severely dried by wind and sun. Recoating is a snap with limited prep required.

The sample pack let us achieve the perfect color for our circa. 1975 Justice Cedar home. The house was acid stripped, ph balanced and hand brushed with woodgaurd/ tamarack. we are very pleased with the finish product and our painter really liked the product as well.

AAA+++ This is the best exterior wood stain we have ever purchased & we have probably bought 5 or 6 others over the years. The difference is amazing & our house is beautiful. Thank you!

We have used Wood Guard for 15 years and wouldn’t consider using anything else. Our last stain job lasted 7 years. This year we are having it redone and adding the Begone to the stain. Carpenter bees love our house too. Thank you for an excellent product. I will be ordering more!

In the trades 45 plus yrs. Used all the big boy stains and oils from SW, BM, KM and so on paint companies bur after using woodgaurd on a cedar shingled home that was in rough shape due to being right on the water where salt fog rain sun and high winds just battered the siding i about #%÷×$&? My pants at the pot life i had after spraying out the finish!!! I could keep spraying without having to back roll right away’ hence allowing greater absorption time. Afer back rolling and some brush work i was beyond myself with the performance and cured finish. Richard Anderson, Alpine painting&home improvment.
