Flexible Waterproofing Slurry System

The great advantage of waterproofing slurries is that they can be used on damp and wet surfaces. Moreover, they harden more quickly and are permeable to water vapor.

Advantages

·         Waterproof

·         Frost resistant

·         Increasing surface protection

·         Covers surface cracks

·         Compatible with sealing tape

·         Can be applied by brush, trowel or sprayed

·         Protects reinforced & standard concrete structures

Application

Surface Preparation

The mineral substrate must be even, solid, load-bearing, clean, crack-free and free of substances that may impair adhesion. The surface must have a rough, open pored structure with good grip. All edges must be cut off or chambered. Cove all corners with a hollow molding of at least 4 cm radius.

Repair any defects, screed over rock pockets and fill mortar joints. Enlarge the cracks and fill them with cement mortar alternatively. If the brickwork is uneven with numerous projections and defects, produce a leveling render made of cement mortar. Make sure to thoroughly prewet the prepared substrate. When waterproofing from negative side, the substrate must have sufficient mechanical strength.

Application

Apply the Slurry with a brush or a trowel in at least two operations. Sealed surface should be protected against too fast drying and the direct exposure to the sun. Apply the second layer only when only when the previous layer is hardened but still damp. If the application of the second layer is also done with a brush – it should be done in a crosswise manner.
