The first step to a flawless professional finish! ColorTone Waterbase Grain Filler is our first choice for filling and leveling the pores of open-grain woods, such as rosewood, ash, koa and mahogany, before spraying a finish. No shrinking or cracking; it dries faster than other types of fillers, and sands easily. Supplied in 4-ounce jars, ready to mix with water.
"It's grain filler, wood putty, crack filler, hole-filler and mistake-patcher, all rolled into one product. The colors are natural and realistic." —Dan Erlewine

ColorTone Grain Filler is supplied in paste form, ready to mix with water (10-15 percent water works well for us) and brush on the wood. Let it dry, sand the surface level, and clean with a damp cloth. It's that easy, and you're ready to spray a smooth, blemish-free professional finish. No shelf-life problems: if the filler dries hard in your cup, simply add more water.
Why use grain filler? Unfinished rosewood, mahogany, koa and ash have porous "open-grained" surfaces. Filling and leveling the pores leaves the surface smooth for applying uniform finish coats. Using a contrasting filler color can often enhance the grain as well.
