APF Epoxy 300 FLEX PASTE – Flexible 100% Solids Joint and Crack Filler
Product Overview
APF Epoxy 300 FLEX PASTE is a 100% solids, medium-viscosity flexible epoxy system designed for high-performance industrial joint and crack repair. With excellent elongation, impact resistance, and bonding strength, this thixotropic paste provides long-term performance in environments exposed to vibration, surface movement, or heavy loads—including steel-wheeled traffic. It bonds tenaciously to both concrete and properly prepared metal substrates.
Developed for use as part of the APF Epoxy 300 FLEX floor system, FLEX PASTE performs exceptionally well on suspended slabs, mechanical rooms, wood decks, and exterior flooring systems. It can also be used to coat properly prepared aluminum and steel, including marine deck applications. A Fast Cure version is available for cold weather or accelerated project schedules.

Installation Notes
APF Epoxy 300 FLEX PASTE should be applied to clean, dry, and properly prepared substrates. Trowel or knife grade application is recommended for filling joints and cracks. When used on metal, surface prep is critical for bonding performance. For cold weather or faster cure times, select the Fast Cure version. Always consult APF’s technical data sheet for coverage rates and cure time details.
