KBE

Technical Specifications

Product Description

KBE is a one-component, water-based liquid bitumen emulsion used as a primer in waterproofing.

Application Areas

• As a primer prior to the application of bituminous membranes of any brand
• In wet areas such as terraces, bathrooms, WCs and balconies, under ceramic tiles
• On basement walls and reinforced concrete shear walls
• On foundations and below foundations
• On mineral surfaces in contact with soil, in planter waterproofing
• Used as a primer on screed in parquet bonding applications with hot bitumen.

Advantages

• Can be applied by brush, roller or airless spray gun.
• Retains its elasticity even at low temperatures.
• As it contains no solvents, it is environmentally friendly and can be used comfortably in enclosed spaces.
• Can be applied on dry and slightly damp surfaces.

Application

• Surfaces must be clean, smooth and sound, and free of dust, oil, dirt, rust, mould release oil, detergent and similar substances and residues that impair adhesion. If there is segregation in the concrete, damaged and loose parts must be removed and weak parts taken off. If there are cracks or cavities in the floor or wall to be treated, they must be repaired with suitable repair mortars. KBE should be applied 3-4 days later.
• The surface to be waterproofed must be dry. Any standing water or ponding must be removed. Before KBE is applied, any expansion joints in the structure must first be sealed using expansion joint tapes and expansion joint adhesive.
• KBE is mixed in a clean container free of any substances that impair adhesion, or in its own container. It is mixed with a low-speed mixer until a lump-free, homogeneous mixture is obtained. Mixing time should be at least 5 min.
• The mixed, ready-to-use product is applied to the surface with a stiff-bristle brush or spray machines. After the material has completed its reaction, the second coat is applied perpendicular to the first coat. The waiting time between coats is at least 1 hour. After the first coat has been applied, the next coats can be applied when a check by hand leaves no trace on the fingers.
