I'm new to the forum and this is my first post. We've only made two
walnut projects so far and one was a kitchen table in walnut, the other a bird cage.
We're not professional woodworkers...here is how we finish
a lot of stuff.
On our table, first we seal the wood with BLO and wait the required days for drying, then stain (if your staining the wood)
I am now a fan of sanding sponges -- and sand between coats.
we used minwax gloss finish poly thinned with turp (about 3 parts poly to 1 part turp) we apply all our finishes with
a rag (mostly a demin rag, cut from old jeans) rub the finish on, wait 24 hours between coats. lightly sand before applying the next coat.
apply several coats, wait several days and then rub on paste wax.
The table is in front of a sunny bay window so the back of the table
looks shiny, however the front of the table shows the soft luster
that can be achieved with gloss poly. when thinned, applied with
a rag and light sanding.
I did use a little stain on this table to get it to match the chairs.
