Performance Pro adhesive boasts sensational adhesion to substrates such as sheetrock, cement board and DensShield. Performance Pro silicone is used specifically for sealing the joints where walls panels meet, where the panels meet the tub/shower base, as well as the joint where the trim piece overlaps the panel.
Both surfaces should be free from dust or other contaminates that could hamper the adhesion process. Sweeping or wiping down these surfaces will adequately prepare them. Be sure that the surface is dry before applying adhesive.
Performance Pro needs air to cure, therefore if you choose to apply in beads, DO NOT seal the perimeter of the panel and make sure the beads are about 3” apart and at least 3/8” thick. If using dots or dollops, each should be about the size of a Hershey’s Kiss, and again 3 – 4” apart.
It is the perfect adhesive to attach the trim pieces. You may consider holding the trim pieces into place with a quality painters tape until the adhesive cures. Some installers use a couple of short 1” strips of double face tape per trim piece in addition to the adhesive. This tape holds the trim into place while the adhesive cures.
Allow at least 24 hours for Performance Pro Adhesive and Silicone to cure.
This is not recommended. Silicone is much easier to ‘tool’, and easier to clean up.
It is not necessary to prime the joints in preparation to apply the silicone, but a good wipe down with denatured alcohol on the joints is highly recommended.
It’s best to begin with a very small angled hole in the nozzle. This first hole should be about the size of a finish nail, and if needed work up from there.
