Punky, spalted wood can yield some of the most intricate grain patterns and texture, but how do you turn or carve it without the whole thing falling apart? That's where Polycryl steps in. A large molecular weight acrylic polymer, Polycryl fills and strengthens semi-punky or spalted wood, making it easier to turn and carve. It's easy and safe to use, dries clear and will not yellow in the wood. Brush it on, or soak the wood in a Polycryl solution. All types of finishes and glues can be used once Polycryl has dried. Note: final product should be finished to seal Polycryl into the wood.
