Uses

• Cement based materials, mineral plasters and concrete
• Thatch, brick work
• Cement boards, gypsum boards , artificial and natural stones

Advantages

• Permeable to water –vapor out
• Water repellency develops fast after a few hours
• Excellent resistance to alkaline attacks
• No change in the materials appearance
• Easy to apply
• Small molecular size, penetrate substrate
• High resistance to aging porous agents, UV and freeze- thaw cycles
• Water penetration resistance by capillary action

Instruction for Use

Surface Preparation

• Wait at least 48 hours after rain, or if the wall has been cleaned with high pressure water, wait 3 days (in dry weather).
• Clean any dirt, oil, old paints, curing compound from the surface.
• Remove any defects and laitance from the surface and fill cracks wider than 0.3mm.
• It is recommended to treat the fresh masonry after 28 days.

Application

• Brushing, spraying or rolling.
• The water repellent must be applied until the surface is saturated.
• One coat is often enough, however, on very porous surfaces a second coat is necessary, apply the next when the substrate has absorbed the previous one and is no longer shiny, (wet-on-we- working).
• Cover the nonabsorbent surfaces and window frames before application.

 Coverage

The consumption is widely varied, depending on the type of substrate and adsorption from 0.3 to 3 lit per m².
