Novalk NFH15903 is a 2K Conversion Varnish clear sealer, specifically recommended for sealing wood or veneered substrates. Characterized by perfect flow, high build, good verticality, and excellent sandability, it provides an ideal foundation for various wood applications. To achieve optimal results, NFH15903 has to be catalyzed with NCH999 at 10% by volume. For reduction, use ND5101 (fast thinner) or ND5920 (slower) at 20-40% by volume. This conversion varnish clear sealer ensures a smooth and durable substrate preparation for your projects.
