Coating the inside of exterior walls is one of the most practical and efficient ways to recover existing buildings, or as a root solution for new projects. Which system to recommend depends on the conditions of the wall and on the intended insulation.

Gyptec boards (simple or insulated) can be directly glued with GA adhesive glue, or applied with a metal support structure.

Application with profiles:

An auxiliary wall-mounted or freestanding structure can be used. Cover the ‘U’ Studs with acoustic tape and secure them to the floor and ceiling. Make sure they are aligned. Do likewise with the side ‘C’ Studs. Fit the intermediate ‘C’ Studs with the recommended spacing (400 or 600 mm). Attach the boards to the profiles.

Direct application with GA glue:

Apply the glue points 40 cm away from each other, while reinforcing the perimeter of each board. The glue can be applied directly onto the board or to the wall.
Attach the board to the wall, keeping it 1 cm away from the floor with the use of shims, to ensure that there is no contact with moisture. After placing them on the wall, press the panels to ensure good adhesion to the substrate, making sure the surface is flat and straight with a ruler. Remove the shims after drying.
