[Woodcarver] cypress knee painting ??

[Ed Ertel]

A shellac based sealer should give you excellent protection against bleed-through.  Some of the older versions of things like Kilz or Bin were shellac based.

The old (traditional) Gesso was made of materials like rabbit-skin glue and marble dust.  It was designed to seal plaster or canvas, and provide a "toothed" surface that would hold oil paint well.

The modern Gessos (Liquetex is one brand commonly found in art shops) are usually an opaque, white, acrylic based paint, which contains minute particles of resin for a "toothed" surface.  They can usually be used with any type of paint as a topcoat.  They have been around for about 50 years, and are pretty well proven.  

One of the newer products on the market is "Clear" gesso, which is a transparent acrylic paint with transparent resin particles in it.

For convenience, I would use one of these latter products, or shellac based sealer, if I faced your situation.

>Just got a batch of knees and many of them have very deep black spots and stains in them.  We usually paint  our Santas with acrylics after they are carved.  But it looks like we will need some kind of base coat, in order to really get the stains covered.  Is there an acrylic primer available?  Any suggestions or recommendations??
