Properties and Use

• Especially suited as water repellent for low-fired clay products (e.g. roofing tiles, common brick, floor tiles, terracotta) as well as various natural stones, sandstones and gypsum
• Consolidation and hydrophobation of mineral construction materials and sand
• Protects brickwork from rising damp
• Suitable for the restoration of natural stone l supplied as concentrate: to be diluted with demineralized water up to 1:100
• High penetration depth and fast curing
• Excellent long-lasting beading effect even at very high dilutions
• Generates water-vapour permeable, colourless treatment
• Excellent reduction of water uptake and soluble salts (e.g. chlorides)
• Significantly reduces the formation of white deposits ontreated surfaces
• Resistant against alkaline environment
• Suitable as binder for silicate-based paints

Protectosil® WS 808 is intended for waterproofing of mineral substrates, in particular roofing tiles and common brick. When diluting Protectosil® WS 808 the product must be added into demineralized water under vigorous stirring. The recommended dilution rate ranges from 1:10 – 1:100, the ideal dilution rate for best performance depends on the mineral substrate.

The amount to be applied depends to a large extent on how absorbent the substrate is and should be tested in advance. For the treatment of common brick a dilution rate of 1:20 is generally recommended at a consumption rate of appr. 0,3 - 0,4 l/m2.
