What is a water-based pore filler and who makes it?
Richard Jones: Many companies offer ready-to-use waterbased filler, and you are bound to find it at your favorite woodworking specialty store. Don’t forget the centuries-old method of using plaster of Paris mixed with powder pigments or waterbased powdered paint. I’ve been using this technique all my working life.
Michael Dresdner: Another handy format for waterbased pore filler is the multipurpose waterbased putty and filler that starts out thick enough to use as putty but can be reduced with water to work as a pore filler.
