Hydrotrim L Trim is a water-activated, self-adhesive drywall corner trim ideal for exposed edges and reveals. The corners are available in 1/2- and 5/8-inch profiles, in lengths of 10 feet. The process of finishing exposed edges and reveals is extremely time-consuming and messy. The product requires only water for application, bonds absolutely to the drywall, and dries within 10 to 15 minutes. Installations are quick and clean, and corners can be finished almost immediately. The product is distributed by Grabber Construction Products.
