lva TT276 is a clear water-based sealer formulated for interior use on light and dark hardwoods, non-resinous softwoods, and engineered or reconstituted wood veneers. Designed for professional finishing systems, TT276 offers excellent clarity, elasticity, and resistance to wrinkling, providing a smooth and even base for topcoats.

It can be used as a 1K sealer or catalysed as a 2K system with Ilva hardeners TXW12 or TXW13 to enhance durability, flexibility, and chemical resistance. This versatility makes TT276 ideal for furniture, cabinetry, panelling, and other fine interior joinery where transparency and surface uniformity are essential.
