WeatherSeal is thick and rich and easy to apply. Formulated especially for log homes, WeatherSeal can be used over all types of outdoor wood surfaces where a natural wood appearance is desired.
There is absolutely nothing quite like WeatherSeal. Unlike typical thin & runny stains, WeatherSeal is thick and rich and easy to apply – not a mess like all the rest. Formulated especially for log homes, WS can be used over ALL types of outdoor wood surfaces where a natural wood appearance is desired. It’s an applicator’s dream: it spreads creamy smooth, there’s no pigment settling, and it soaks into the wood like a much thinner stain. Due to its thick consistency, you get more WS protection per brush stroke because more stain can be deposited on a vertical surface without dripping off.
Product Type: Oil based formula
Uses: Logs, Wood Siding, Decks, Railings, Wood Shakes
WeatherSeal in Canyon Brown
Special Note: In July, 2014, WeatherSeal was reformulated due to environmental considerations. The replacement ingredient provides a cleaner environmental profile. Previous customers will notice it is still very thick but not super thick as the previous formula. The core ingredients are the same. The color of an open container of the thicker version may look different than the newer thinner version due to the difference in thickness. Pigments have not changed and BOTH versions may be intermixed.

Surface Preparation for new, bare wood
Great Preparation is the Key to Application Success!
Surface Preparation for weathered, gray wood
Surface Preparation for maintenance cleaning
To enhance the existing finish and provide a cleaner surface so that any insect additives
will continue to work better a yearly maintenance cleaning is recommended.
Surface Preparation for wood with mold and mildew
Check the Moisture Content of Your Logs
Do not apply WeatherSeal to wood over 18% moisture content. Applying two coats of WeatherSeal on wood with over 18% moisture content will create an environment where mold and mildew can grow beneath the surface of the wood finish creating peeling and lifting over time. Apply one coat of only of WeatherSeal over green wood or wood that has moisture content of 18% or more.
To test the moisture content of your wood, borrow a moisture meter from your contractor or purchase one at your local hardware store. For quick reference:
Laminated logs: The moisture content of laminated logs is generally below 14%. These logs are usually ready for immediate application of WeatherSeal once they have been cleaned and allowed to dry for the appropriate amount of time. Always use a moisture meter to confirm the moisture content.
Kiln-dried or air dried logs: Use a moisture meter to check.
Green, wet, or treated logs: These logs have moisture content greater than 18%. Allow the logs to sit in a dry area and check their moisture content on a regular basis. Logs with high moisture content can take up to 6 months to 1 year to reach the appropriate 18% or below moisture content for applying WeatherSeal.
Apply a Wood Preservative
Have your logs been pre-treated with a wood preservative ( borate ) at the factory or mill? Contact your log or siding provider if unsure.
What is a wood preservative?
Wood preservatives ( borates ) make wood toxic to wood damaging organisms such as powder post beetles, carpenter ants and fungi. Wood preservatives do not protect against Carpenter Bees and other wood drilling insects, only those that ingest wood. Click here to find out about additives available for prevention of Carpenter Bees.
Why apply a wood preservative before applying WeatherSeal?
Applying a wood preservative can protect your home from damaging organisms for the life of the structure. WeatherSeal contains mildewcides, insecticides, water repellents and UV protectants; it is not a wood preservative. LogFinish.com recommends applying ShellGuard RTU or ShellGuard Concentrate to your logs before applying WeatherSeal.
Caulk All Gaps and Checks
WeatherSeal may be applied over cured latex caulks without harm to the caulk. If possible, caulk first before staining with WeatherSeal. However , if applying a latex caulk or synthetic chinking over a WeatherSeal coated surface, lightly sand over the areas of WeatherSeal that will come in contact with the latex caulk or chinking to insure good adhesion of the caulk.
It is natural for wood to crack/check over time due to changing seasons, temperature and aging.
Fill any spaces between the logs and upward facing cracks/checks in the wood after applying a wood preservative ( borate ) and before applying WeatherSeal. Fill all joints, cracks, and nail holes with a good quality acrylic latex caulk/filler created specifically for use with wood like Energy Seal or Check Mate 2 prior to applying finish.
Test the Stain
We always recommended performing a two coat color test to a clean, dry, bare area of the structure that you are planning on applying WeatherSeal. Please Note: WeatherSeal is difficult to remove once it has been applied. Before doing a full application make sure that your color selection is correct, has a look you want, and a maintenance schedule you can manage.
Weather Conditions during Application
Temporary Color Change When Wet
Because of WeatherSeal’s unique chemistry, a color change will occur with WS when it is wetted. In areas where water puddles and accumulates (from rain, dew, sprinklers, etc.) on the dried stain’s surface, WS will temporarily turn to a lighter milky hazy color. Once the water dries, WS will return to its normal color. Over time, this
“water-spotting“phenomenon will diminish and will be barely noticeable. Nothing is wrong with WS nor is its performance compromised when this color change occurs. It is only temporary and of course it is most noticeable on
flat surfaces where water puddles. The color change is most extreme when WS is recently applied.
Regular maintenance and annual attention to your log home can save you money and time. Proper maintenance starts with visual inspection. Weather, exposure and altitude may vary, so maintenance may be needed sooner than later in some locations.
When WeatherSeal is showing signs of wear and no longer effectively protecting the wood surface, it is time to re-coat. Depending on the severity of the wear, 1-2 coats of WeatherSeal in the same previous color are recommended to effectively restore and protect the wood surface. As always the wood surface must be properly prepared prior to application to insure best performance.
To prolong the natural look of WeatherSeal, it is important to only pressure wash and apply a maintenance coat when it begins to show obvious signs of deterioration like fading, chalking or flaking. Those areas that reveal bare wood or show signs of deterioration should be washed with log cleaner, rinsed completely with clean water, and once dried lightly sanded with 180-220 grit sandpaper and then touched up with the same color.
WeatherSeal is available for shipment by ground only and is shipped via FedEx. No shipping to the Southern
California Orange County Air District.
Shipping to Canada is permitted. However, orders will be drop shipped from the manufacturer with bilingual labels on containers.

Stain is excellent. Have applied it at numerous times in 13 years for my log home built in 2004. The only negative comment I have is I have to touch my log home up with it annually. When sleet or hail hits my log home it continually chips down to bare wood and stain flakes off , Every year I have to restain most of my home that gets hit with bad winter weather. Any advice or assistance from others greatly appreciated. I am getting much older now and it is getting harder each year to keep restaining. Thank you!

Just bought another five gallons of weatherseal cabin brown for a third go around on the cabin in sixteen years. We’re in the northern Wisconsin and siding takes a beating. No better product out there for semi- transparent stain bare non. My only critique is that it shows brush marks on smooth surfaces like the tongue and groove pine soffits, but beautiful on rough hewn cedar siding which is the majority of surface area.

Built a new log home for a lake house in 2012, used two coats of the WeatherSeal Oil Base to stain the exterior. The Product was easy application, exterior appearance even after five years is still outstanding! In keeping with the Manufacturers recommended log home maintenance applying a new coat (single coat) this year. GREAT PRODUCT! Would highly recommend it to all log home Owners

We used WeatherSeal Exterior Wood Finish in the Autumn color on our log home 1 year ago and it still looks great. When we opened the can it looked a little more orange then we thought it should be but after applying it looked beautiful. Of course it will darken over time. It is very thick but easy to apply. We applied with brushes and it blended great,no lines or streaks. I would recommend this product to anyone that is considering staining their log home.
