How often should you stain a log home?
Takeaways
- South and west walls wear out first. You may not need to restain the whole house.
- The water test is the real answer: beads means OK, soaks in means restain.
- Check once a year, in late spring after the pollen.
- If half the color comes off on packing tape, the old finish may need stripping first.
Why isn’t there one number?
Because the sun doesn’t hit every wall the same. Perma-Chink, which makes log stains and chinking, says film-forming or oil-based stains need reapplying “every 2-3 years depending on the sun exposure”. Their stain-plus-topcoat system can stretch that, and they say it “may be years” before a restain.
On a cabin up here, the south and west walls get the most sun and the worst weather. The north side under the spruce might hold up twice as long. That’s normal.
How do you test log stain?
There are three easy checks, all from Perma-Chink’s maintenance guide:
- The water test. Spray a dry log with a spray bottle. Water that beads up means the finish is working. If it soaks in, it’s time to reapply.
- Fading. Color going pale or patchy is the stain wearing through.
- The tape test. On an older finish, press packing tape on the log and pull it. If 50% or more of the color comes off on the tape, the house needs restaining and possibly stripping to bare wood.
Test each wall separately. Write down which ones failed. That’s your restain list.
When should you check it?
Once a year. Perma-Chink suggests late spring, after pollen season, for the yearly wash and inspection. That timing works well here: you find out in June what needs doing, with the whole summer left to do it.
When is the best time to restain in northern Minnesota?
Summer into September, on dry days. The logs have to be dry before stain goes on, so a wet week pushes the job back. In Duluth, NOAA’s normals put the average October low at 35.6°F, so fall restaining gets risky fast. More on that in how cold is too cold to paint outside.
What happens if you wait too long?
Once the finish stops shedding water, the wood starts to gray, check and take on moisture. A coat that would have been a quick wash-and-stain turns into stripping or sanding first. Catching it a year early costs less than catching it two years late.

Questions
How many years does log home stain last?
Perma-Chink puts film-forming and oil-based stains at about 2 to 3 years, depending on sun exposure. A stain with a clear topcoat can go longer. Shaded walls often last well past the sunny ones.
How do I know if my log home needs to be restained?
Spray a dry log with water. If it beads, the finish is still working. If it soaks in, it needs another coat. Faded or patchy color is another sign.
What is the tape test for log stain?
Press packing tape onto the log and pull it off. Perma-Chink says if half or more of the color comes off on the tape, the house needs restaining, and maybe stripping first.
When should I check my log home?
Once a year. Perma-Chink suggests late spring, after pollen season, as a good time to wash and inspect.
