Red Devil?s PRO Industrial Grade RTV 100% Silicone sealant is ideal for use in most OEM and maintenance applications. The Case Pack comes in a box of 12 10.1-ounce tubes for convenient storage and a perforated opening for easy access. The sealant forms a strong, durable, and weather-resistant seal and provides excellent adhesion to most non-porous surfaces. It offers excellent adhesion, flexibility, and impressive durability and can be used on a variety of surfaces indoors or outdoors. Use on window and door frames, siding, baseboards, showers/bathtubs, gutters, plumbing fixtures, countertops/sinks, loose tiles, or any other surface silicone adheres to. The multi-purpose sealant withstands the elements and won't crack, peel or shrink when applied correctly. For best application, remove any old caulk with a razor blade, as silicone doesn't adhere to itself or other sealants; clean and dry the surface before applying the sealant for a tight adhesion. Cut the nozzle/spout at a 45-degree angle for desired bead size. Please note that the silicone sealant is not paintable, so be sure to complete the painting of the surface prior to sealant application.
