There are several instances in which using silicone with Trusscore is necessary. The most common will be whenever there is a presence of water on the panels. The amount of silicone used will differ depending on the application.In applications such as showers for example, a large amount of silicone is required to seal all panel seams, ends, and corners where water can penetrate. Refer to our Installing Trusscore in Shower Applications Guide for more details.An indoor pool, however, might use less silicone since the water is not constantly hitting the walls and you likely will only need to seal the bottom corner to direct water splashes away. In commercial food processing applications, specifically in Canada, CFIA regulations call for the use of silicone on all joints for wall and ceiling cladding materials to provide a smooth, flush, and impervious joint. For adhesion purposes. For example, when replacing a damaged Trusscore panel and fastening with screws is not an option, silicone must be applied to the back of the panel to hold it in place. Also, when installing Outside Corner Square trim, silicone is used to adhere the trim to the Trusscore panels instead of screws for a clean finish. Each of these instances are unique in their requirements, so refer to our blog post Adhesives & Sealants 101: Everything You Need to Know for information on which silicone to use. Always consult the silicone manufacturer label to determine the best product to use for the surfaces in your application.
