Log end treatment - Sawmill Creek Woodworking

I am getting ready to take a load of walnut logs to a sawmill for rough cutting. Just wondering if anyone seals the ends before they are cut, or do it after they are cut. Also, what is the best product to use on the ends. I have seen logs cut with and without the sealing, and I prefer to seal the ends, to keep worms and bugs out. If I was going to use the lumber up immediately, I would not bother, but I have over a bf., and it will take me a few years (or more) to go through it, then when I'm done with it, another load will go to the mill. I will be storing it all, stickered, in a covered, dry barn.

Thanks.

Logs should be end sealed with a wax-type sealent as soon as they are cut into logs. The longer you wait the more the logs can be damaged. The damage occurs during the first 4-5 days.

The best sealent is AnchorSeal. It's a water emulsified paraffin wax and is the most effective preventor of moisture tranmission.

Paint, particularly latex house paint is a poor choice. Both interior and exterior latex paints are designed to allow moisture to penetrate. This is so the paint does not peel and bubble as moist warm air forms condensation.

Another vote for Anchorseal.

Also, like Richard said, the logs should be sealed immediately after cutting to prevent end checking. If the log ends have already started to check, cut off a few inches to sound wood and then seal asap.

Many sawmills will have Anchorseal on hand so you might check with your mill before purchasing it. I get mine through a local turning club that orders it in 55 gal. drums.

Any of you guys have a source for the Anchorseal? I have a small can of it, but I will need alot more. The local lumberyard has some in the small cans, but it is steep. Didn't know if there was a better source.

Thanks.

U C Coatings is the manufacturer of Anchorseal. They have an on-line store. A five gallon bucket is about $75 shipped to the eastern U.S.

And if at all possible seal the logs as soon as you cut the tree. The sooner the better. This won't keep bugs out (as asked by OP) but it does slow the drying at the end grain and will prevent most if not all cracks from forming.
