Description
ARBO® AFS Primer (1L)
High-Performance Primer for Porous Substrates
ARBO® AFS Primer is a one-part, solvent-based, air-drying primer formulated to enhance adhesion on porous and absorbent surfaces. Based on an advanced polyacrylate/silane blend, it’s designed to prepare substrates prior to installing ARBO® EPDM membranes and compatible ARBO® adhesives.
Fast-drying and easy to apply, AFS Primer helps create a reliable bonding surface on concrete, timber, cement boards and other porous materials, making it an essential step for professional membrane and sealing installations.
