APF Polyurethane 250 – Acrylic Urethane Primer & Sealer for Concrete
Product Overview
APF Polyurethane 250 is a two-component, low-viscosity acrylic urethane designed for use as a primer or sealer over concrete, architectural surfaces, and decorative finishes. This product offers superior penetration and adhesion to minimally profiled concrete thanks to its unique blend of solvents and adhesion promoters. UV stable and fast-curing, it can be used in both interior and exterior applications and re-coated with either water-based or solvent-based polyurethanes.
As a finish coat, APF Polyurethane 250 delivers a hard, high-gloss surface with excellent stain resistance, gloss retention, and easy cleanability. It outperforms traditional solvent-based acrylic sealers and is available in a satin finish. A low-VOC version is available to comply with strict environmental regulations.

Installation Notes
APF Polyurethane 250 should be applied to clean, dry, properly prepared surfaces using a roller or airless sprayer.
