Log Stain Tips
To Protect and Serve
Applying log stain is the best way of protecting your log cabin. The stain seals the logs from absorbing moisture, repels rain and blocks the harmful UV-rays of the sun. Staining your logs is a big job but you can save some work with these tips. By doing it right the first time your stain job will look better and last longer.
Log Stain Tips for Log Cabins
- Clean the logs first New logs have mill glaze, road
dirt and sawdust on them, old logs have spider webs, mildew and dirt splashes.
Scrub by hand with TSP (trisodium phosphate) and bleach, if needed, and hose off gently. If you use a
pressure-washer be very careful with the setting, the nozzle size and
how close you hold the nozzle to the logs. It’s very easy to damage your logs
badly with an uncontrolled pressure-washing. Let the logs dry for several days
- Brush or spray on the stain First you have to deliver
the stain to the log. Spraying the stain using a portable sprayer is a very efficient way to do this but be sure
you follow up with back-brushing. Alternatively you can brush on the stain by
hand and smooth it as you go. This is best if there is only one person doing
the staining. Use plenty of stain – you don’t want to starve the logs of their
protection. We like the TWP stain series.
- Back-brush the stain If you don’t back-brush it the
stain will just sit on top of the logs. Brushing it forces it into the pores
and cracks of the wood and gives an even, smooth coat. It’s best to use a wide,
universal-bristle brush and straight, long strokes for a consistent finish.
- Stay out of the sun Stain dries very quickly in direct
sunlight and makes it difficult to keep a wet edge. You’ll have better results
by staining on the shady side of the log cabin. It also helps to do your
staining on cool days or in the morning before the afternoon sun heats the logs
- Keep a wet edge The worst thing you can do is have the
stain dry out and leave a line where you ended. By only working on 3 or 4 logs
at a time all the way across the log wall you can keep a wet edge going and
catch any drips or runs.
- Start at the bottom If you start at the top of the log
wall, any drips will usually soak in to the lower logs before you can do
anything and this will be visible later. By starting at the bottom of the log
wall, any drips will blend into the stain already applied lower down.
- Always apply a minimum of two coats Some people think
that because one coat of log stain looks so good it must be enough.
One coat is not adequate protection from the damaging sun and weather. Two
coats will last much more than twice as long as one coat and three coats of
stain is even better protection for your logs.
- Wait the correct time between coats You can’t go back
and immediately begin to re-coat the stain. It’s important to let the first
coat of stain dry before doing the next. On the other hand, if you wait too long
the first coat can get dirty and the second coat of stain won’t adhere as well.
One day between coats is a good time.
- Buy enough stain You certainly don’t want to run out of stain in the middle of the job. Although average coverage for stain may be around 200-250 square feet per gallon, the majority is used on the first coat where the coverage is around 100 square feet per gallon. The raw wood soaks up the stain and makes this coat take longer to apply. Coverage increases to around 400 square feet per gallon on the next coat. This second coat goes faster than the first because the stain doesn’t soak in as much. On this coat you have to be very careful about drips and runs. Go back over your work carefully and brush out any drips you see before they dry.
- Buy a 5-gal pail of a good quality stain like this TWP stain will ensure that you have enough for the job and that the color will blend better than mixing individual one-gallon cans.
- Protect the logs Think of stain color like the SPF rating on sun-block: the darker the stain, the better the protection of your log home from the damaging UV-rays of the sun. Remember that the more coats you apply, the darker the stain will be as well.
- Continue maintenance Do a regular bi-annual check of your log cabin (check out our page on spring maintenance tips or read our fall cabin maintenance guide) and assess your stain. Water-based log stains seem to last 3-5 years and oil-based log stains last about 5-7 years before re-coating is necessary. If you want to further protect your logs without darkening them, apply a clear finish coat.
You’ll protect your logs for years to come with a proper log stain application. Pick the best log stain, apply it right and keep an eye on your job to ensure many years of enjoyment and minimum maintenance costs with your log cabin.
