Pronounced (poly-crill), this product works well with turning very soft, spalted or punky wood. Polycryl is an acrylic polymer that comes in a concentrated form and is diluted with water before applying it to the wood. It is applied in successive applications of thicker solutions until the wood is ready for turning. It is recommended to rough turn the piece first. The softer the wood, the better the penetration.Polycryl Directions
