The tackboard should be installed over 3/8 in. plywood or 1/2 in. gypsum wallboard. Never install directly to studs.
Panels to be acclimated to room temperature for a minimum of 24 hours.
Panels should be matched for color orientation before applying adhesive.
Use a good construction adhesive. If using a notched trowel, do four stripes. One down each side and two in equal distances on the board. If using tubes, we suggest a figure eight, or double X pattern. A bead of adhesive needs to go down both sides near edges.
If board wants to lift, use 3 in. by 3 in. by 1/8 in. squares of plywood squares with a dual head nails to hold panels in place until adhesive cures. (Note: Drive nail through the plywood squares first so the nail may be worked into the joint without going through the vinyl facing).
Adhesive should be tested before use. Adhesive manufacturer's installation instruction supersedes us. (They are ultimately responsible for bond failure)
