Fiberglass Scrim Reinforcement

About Pro Grid Reinforcement

Pro Grid reinforcement provides an efficient application with the same hard-wearing surfacing as our traditional Pro Fleece Reinforced system. The Pro Grid helps mitigate telegraphing cracks through force distribution. The installation of Pro Grid is efficient - prime, reinforce, and waterproof in one step. Pro Grid Reinforcement is embedded in Pro Primer and is followed by Terapro and Terapro VTS Wearing/Surfacing Components.
