It's hard to tell exactly what you are using. If you are surfacing the board you couldn't tape off the Maple. Are you talking about a wood putty filler...like a repair putty or a paste wood filler/grain filler?While finishing my maple and walnut chess board, will the Walnut colored Famowood filler darken the maple?
Or will it sand off, or should i use natural oak color?
Gees, I didn't know famowood made a grain filler. You especially would need to keep it off the maple. It basicly is wood stain with a lot of solids. On a chess board I believe I would fill the grain with a clear grain filler such as Crystalac or just use a lot of sealer. If you got the color on the maple it would take so much sanding to get the stain out you would have to grain fill the walnut again.It is paste wood grain filler.
