Waterproofing

Mortar intended for sealing construction substrates to be found outside and inside buildings. It is applied for protection from rising damp of external walls, foundation walls, pedestals and walls in rooms of increased humidity such as basements, bathrooms and shower rooms. Makes up a waterproof layer of light, medium or heavy type. It is especially recommended for performing a base coat (reinforcing coat) before applying thin coat renders, finishing paint coatings and ceramic and stone linings. To be applied on all typical mineral substrates (such as: concrete, cement floor topping, cement render, cement-lime render, gypsum plaster and other raw surfaces made of bricks, blocks, concrete blocks and other ceramic or silicate materials of that type) as well as on substrates covered by extruded or expanded EPS boards (the one with reduced absorptivity is recommended).

• Efficient protection from rainfalls and ground water
• Efficient protection from moisture present in
the rooms with increased humidity
• Makes up a waterproof layer of light, medium or heavy type
• Protects from moisture penetration and capillary action
• High resistance to shrinking cracks
• High vapour permeability
• Optimum impact resistance
• High adhesion to the substrate and EPS
• Simple application and surface levelling out
• To be applied outside and inside buildings
• Contains microfibres
