Q: I have a solid teak dinning table that has a very bad and large dark water stain and I would like to get it out. How do I go about doing that?

Q: I am making blocks for my granddaughter and plan to use Ceramcoat acrylic craft paint to give them some color, but can not find out if the paint is child safe. The MSDS does not address the paint once it is dry.
A: Actually, it does. Section three of the MSDS says, and I quote, [...]
Q: I understand that using a pretreatment while staining maple and other woods prone to blotch will reduce the blotchiness, but you end up with a lighter colour. How do you reduce the blotchiness and keep the same colour that you started with?
A: There are two ways; either start with a darker color in anticipation [...]

Q: I usually finish the soundboard of my classical guitars with dewaxed shellac. It has no color at all and therefore the soundboard ends up being very pale. I noticed all classical guitar sound boards are more toward a brown tint. My question is, do you think luthiers stain their soundboards only by using different [...]
Q: Can I add dry pigment to lacquer to color it?
A: In theory, yes. In practice, it is almost impossible to get pigment powders to disperse uniformly in liquids. When we add them in the industry we use tools specifically designed for forcing pigments to combine with liquids, such as ball mills and high shear [...]
Q: I have a lot of tubes of various oil paints on hand. Could I use oil paints as a pigment to add to lacquer?
A: If you are talking about concentrated oil colors in paste form in tubes, yes you can mix a small amount into lacquer, but don’t try to add too much. Even [...]
