Perma-Patch Los Angeles. The Perma-Patch spot repair system from Perma-Liner is being used frequently in Los Angeles and surrounding areas. The Perma-Patch is sold in kit form, so there’s no measuring or waste. Perma-Liner is also offering Silicate Resins with the Perma-Patch kit, which allows maximum working time while achieving a short cure time. Many of our Los Angeles certified installers are also running a two-man crew to install the Perma-Patch kits. Less man-power = more profitable! If you live in Los Angeles and would like to see a live Perma-Patch demonstration or would like more information… please contact Perma-Liner anytime!
