I’ve built a couple of tops for very old nightstands and plan to use a grain filler (Aqua Coat Clear Wood Grain Filler) on them to get a smooth top, followed by several coasts of Watco Danish Oil (to match the bases). The tops are quarter sawn white oak. I always finish both sides of tops to ensure that both sides react the same to temperature and humidity changes. But, I can’t think of a reason why I should put grain filler on the bottom of the top that will sit on the base. Do others use grain filler only on the visible sections, or do you put it on all surfaces, even those that won’t be seen? Thank you for your advice.

I wouldn’t, but I’m sure there are others that would.

I use a different grain filler (TimberMate) but only do the show sides and have had no cupping/warping problems. But I do finish both surfaces.

Thanks for the replies. I’ll put filler only on the visible sections, but finish all surfaces.

No reason to fill the bottom not visible part, but finish all non glued surfaces.

Have your say...
