What is the best sealant to use for preserving woodcarvings.

Since they are going to be outside, use marine epoxy.

You are good!!! Use a marine grade varnish/polyurethane whether they will be inside or out.

I have nothing to add, but so admire your craft! Love these and you certainly have the hang of it! Look into selling at local craft fairs - these always do well. 😍

First check with a hardware store, then go to Homedepot or Lowe's, and go the seasonal dept. Where they have lawn ornaments. See if you can find a wind mill or a single statue of a girl or animal. Then ask if they know what they used on the wood for a finish. This could be helpful, and you should experiment with say 3 small cans of different sealers on some scrap wood you have. See what you like and return the other 2. Good Luck. I admire you skill, it takes a lot of work.

Could this sealant be used on bird houses?

I use a mix of beeswax and mineral oil. (oil is 97 cents a pint at Walmart, used as a laxative)

I have a old crock pot and mix it in different proportions.

for outdoor things, i use less wax.

this mix allows the wood to transpire, and protects it well, my counters bead water and don't stain.

Totally non-toxic!! It does not support bacterial growth. As with most finishes, it will darken the wood.

I us on bird houses, benches, butcher block, and tool handles.

Love your carvings! They're beautiful!

I would use a matte or satin finish deck sealer. Especially if the piece will be outside! Love the carvings, very nice work.

There is a product that will keep wood sealed and keep it from cracking but I don't know the name of it.

You are very talented. Love your Carvings.
