Before the installation

Before the installation the panels should be stored away from rain and moisture. Remove soil from the root of the plinth up to the frost insulation. Mechanically remove loose dirt and large irregularities from the plinth. The panel is attached to the plinth with attachment or renovation plaster. Follow the manufacturer's instructions on mixing, soaking period and operating temperature of the plaster. Depending on the roughness of the plinth, one 15-20 kg bag of plaster will suffice for 3-5 plates. Plaster is spread with a toothed spatula from the bottom upwards. This way, any possible moisture in the plinth can flow down the "plaster tracks" to the ground.


Start installing panels to the outer corner and then continue installation with full-sized panels. Shape panels with a circular saw, a hand saw or a carpet knife, if necessary. If the plinth is uneven, you can straighten it by shaping the Amperla Thermo insulation panel. Install panels tightly to the butt joint (make sure that plaster does not dribble into the seams). You can leave a 0.5 – 1.5 cm gap between the panels, which is then filled in after the installation with adhesive sealant approx. 0.5 cm away from the surface of the panel. Press filling sand into the wet adhesive sealant so that the seam will not be visible. Support the panels against the plinth while the plaster dries.
