Enduro Water-Based White Undercoat

General Finishes Enduro White Undercoat is a professional-grade, high-solids water-based primer designed to provide a smooth, sandable base for white and off-white finishes. Similar to General Finishes Sanding Sealer but fortified with white colorant, this heavy-bodied formula builds quickly and sands easily for efficient workflow. Both interior and exterior rated, it is ideal for use under pigmented topcoats and performs exceptionally well on MDF. For darker custom colors, use Enduro Deep Base Undercoat instead.

Key Features:

• Optimized for Light Finishes – White-pigmented formula provides an ideal base for white and off-white topcoats

• Fast Build & Sanding – High-solids, heavy-bodied formula allows quick film build and easy sanding

• Interior & Exterior Rated – Versatile performance with excellent results on wood, MDF, and existing finishes
