OBEX CORTEX 0787FR Non Flammable Primer - 4L by Obex Protection

The OBEX CORTEX 0787FR is a non-flammable primer achieving a Class B fire classification to EN 13501-1, designed for preparing building substrates prior to the application of OBEX CORTEX FR self-adhesive membranes. The 0787FR improves adhesion on porous, dusty, or poorly keyed surfaces, including concrete, masonry, smooth render, and timber.
