Topic tags/keywords: finish poly question sapele

Working on a garden bench whose sapele top is 20” wide, 4’ long and nearly 2” thick. It’s heavy.

I put the final coat of Epifanes on top and it looks great. But now I need to deal with the underside and I’m afraid of turning it over to do the work. I have trouble trusting the Rocker bench cookies and particularly the pointed pyramids with something that heavy since they might leave marks (and did when I turned it over during some tests).

I could lay it flat on the table instead, but when can I be sure that I won’t interfere with the top? Is it really a month before the poly is really cured?

If you’re that scared, wait another day with a fan on it, then flip it over with a blanket on it. It can be dry for practical purposes even if its still curing.

I always finish the bottom first because I’m paranoid about thus as well. I agree with the blanket trick. Have used it before. Use one you don’t care about because it is bound to get drips of finish on it.

Thanks for the replies. I’m mostly gun-shy because the indentations these pyramids left earlier since the top is so heavy. Then after another piece was finished I used the rubber pads themselves but they left a crosshatch pattern in the finish.

Have your say...
