What are the five steps for proper joint preparation and sealant application?
1.) Clean — joint surfaces must be clean, dry, dust free and frost free. 2.) Prime — if required, primer is applied to the clean surface(s). 3.) Pack — backer rod or bond breaker tape as required. 4.) Shoot — sealant is applied by “pushing the bead” into the joint cavity. 5.) Tool — tooling techniques are used to strike a flush joint and make certain the sealant has the proper configuration and fully contacts the joint walls.
