AC WOODLAK®
Sanding Sealer
AC WOODLAK® Sanding Sealer is a premium two-component acid catalysed clear sanding sealer formulated from alkyd and urea formaldehyde resins for professional wood finishing applications. Designed for solid timber, veneered timber, and medium-density fibreboard (MDF), it provides exceptional sealing, filling, and sanding performance while preserving the natural appearance of timber beneath clear finishing systems. Its high-build formulation fills surface porosity, seals MDF edges, and creates a smooth, uniform foundation for reaction lacquers, nitrocellulose lacquers, and polyurethane topcoats. The sealer sands effortlessly to produce an exceptionally smooth surface, reducing finishing time while enhancing the final appearance of premium furniture and interior joinery.
Available in 5L, 20L & 200L kits.

Intended Uses
AC WOODLAK® Sanding Sealer is developed for high-quality interior furniture and joinery where exceptional surface preparation is essential before applying decorative clear or pigmented finishes. The sealer penetrates and seals timber fibres while filling surface porosity to produce a smooth, uniform substrate that sands easily and promotes excellent adhesion of subsequent finishing coats. It is particularly effective as a high-build sanding sealer for closed-pore finishing and as a thinner isolation sealer when producing open-pore decorative timber finishes. Its excellent clarity makes it ideal for premium furniture, cabinetry, architectural joinery, and decorative timber applications where the natural beauty of the wood must remain visible beneath the final coating.
