Description
Underglass is a premium two-component wood sealing yacht varnish developed for use on solid wood and plywood in marine environments. Designed as a high-performance base coat, Underglass prepares wooden substrates before the application of one- or two-component yacht varnishes or yacht paint finishing systems, ensuring superior adhesion, durability, and long-term performance.
This advanced sealer is formulated to provide excellent penetration into the wood structure, effectively sealing the surface and stabilising the substrate. By deeply bonding with the wood fibres, Underglass reduces absorbency and creates an even, controlled base that enhances the performance of subsequent coating layers. This makes it an essential first step in professional wood finishing and varnishing systems.
Underglass is fast drying, allowing efficient workflow and reduced preparation time without compromising finish quality. Once cured, it delivers strong adhesion to the substrate, ensuring that topcoats bond securely and perform as intended. The sealed surface helps prevent issues such as uneven absorption, poor adhesion, and premature coating failure.
Compatible with both one- and two-component paints and varnishes, Underglass integrates seamlessly into a wide range of Skipper’s Line coating systems. It can be overcoated with high-gloss, satin, or matt varnishes, as well as yacht paint topcoats, making it a versatile solution for interior and exterior wood applications.
Ideal for professional boatyards and experienced boat owners, Underglass wood sealing yacht varnish provides a reliable, technically advanced foundation for achieving durable, beautifully finished wooden surfaces. Whether used on new timber or as part of a refurbishment project, Underglass ensures consistent results, improved coating performance, and long-lasting protection in demanding marine conditions.
