Preparation of surfaces
The surfaces must be free of dust, dirt, grease, oil etc.
Preparation of the product
Add under stirring 20-25% of water and mix with a mechanical mixer or by hand until amalgam is smooth on desired consistency, dense and free of lumps.
Product Application
Used as adhesive: apply the R17 EXTRA mixed over the entire surface with a notched trowel. For panels of small dimensions, the application of R17 EXTRA can also be performed in spots by trowel. Proceed then with the mechanical fixing with appropriate bolts. Used as topcoat plaster: apply the R17 EXTRA at least 24 hours after the laying of panels in a uniform manner over the entire surface, and drown an alkali-resistant fiberglass network, by overlapping for at least 10 cm in the joints.
Estimated yield
Topcoat plaster: About 1.4 kg / m² per mm of thickness (recommended thickness 4mm in 2 layers)
Adhesive: with a uniform layer on the entire surface 4-6 kg / m². In spots 3-4 kg/m².
