Product catalog summary

Overview: The document provides technical details on VANDEX CEMELAST, a two-component, polymer-modified waterproofing slurry, and VANDEX CONSTRUCTION JOINT TAPE, used for sealing construction joints. It highlights their applications, specifications, and technical data.

Specifications: VANDEX CEMELAST is a cementitious, efflorescence-free waterproofer with hydrophobic properties, suitable for concrete, masonry, and render surfaces. It is resistant to water and moisture, tested for use in drinking water reservoirs, and effective in areas prone to cracking. The product is compatible with VANDEX BB 75 and provides a waterproof and elastic coating tested up to 1.5 bar.

Application Procedures: The application involves placing the VANDEX CONSTRUCTION JOINT TAPE onto the first coat of VANDEX BB 75 E or VANDEX CEMELAST, embedding the tape's fabric edges, and overcoating with a second layer. VANDEX CEMELAST can be applied by spray or trowel in two coats.

Consumption and Coverage: For ground moisture, a film of surface water requires 4 kg/m² with a 2 mm thickness. For water under pressure, 6 kg/m² with a 3 mm thickness is needed. The product is suitable for both horizontal and vertical surfaces.

Technical Data: The wet mix density is approximately 1.65 kg/l, with a setting time of 2-4 hours. Adhesive strength is 1.2 N/mm², elongation at rupture is 13% at 20°C, and crack bridging capacity is 0.4 mm. The product remains flexible from 20°C to -20°C.

Recommendations: VANDEX CEMELAST is recommended for waterproofing structures subject to hydrostatic pressure and those not subject to it. It is suitable for areas with potential cracking and offers high/low temperature flexibility.

CEMELAST Elasticized Waterproofing Slurry waterproof, tested up to 1.5 bar suitable for areas of potential cracking tested for use in drinking water backfilling after 3 days high/low temperature VANDEX CEMELAST VANDEX CONSTRUCTION JOINT TAPE VANDEX CONSTRUCTION JOINT TAPE external application at horizontal and vertical construction joints. SYSTEM DESCRIPTION VANDEX CEMELAST as external waterproofing. VANDEX CEMELAST as internal waterproofing. VANDEX CEMELAST is a cementitious, two-component, polymer-modified – and efflorescence-free surface waterproofer with hydrophobic properties. It is resistant to water and moisture, and made by mixing VANDEX BB 75 (dry component) with VANDEX CEMELAST LIQUID. VANDEX CEMELAST is applied to surfaces such as concrete, masonry and render, which need to be sealed and protected against the ingress of water and moisture. Because of its elastic properties it is used in zones posing cracking or deforming problems. VANDEX CEMELAST has been tested for use in drinking water reservoirs. Due to its composition of cement, quartz with well graded aggregate, and special chemical ingredients, as well as the admixture of the polymer component, a waterproof and elastic coating is achieved (tested up to 1.5 bar). VANDEX CEMELAST is suitable for areas of potential cracking. It is compatible with VANDEX BB 75. The initial and final bonding ability of VANDEX CEMELAST is excellent, making it suitable to be applied on horizontal as well as vertical surfaces.
