What is a water-based pore filler and who makes it?
Richard Jones: Many companies offer ready-to-use water-based 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 water-based powdered paint. I’ve been using this technique all my working life.
Michael Dresdner: Another handy format for water-based 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.
