Waterproofing - CERESIT® CR 65 Rigid is used on the horizontal and vertical substrates of buildings, structural components and tanks : for waterproofing against water loads, for waterproofing monolithic water tanks from inside as well as drinking water tanks and swimming pools, for subsequent waterproofing on the negative side, for filling drill holes cavities in combination with the silicifying fluid CO 8 Concrete protection - CR 65 is perfect prepared to improve concrete substrate resistance, even having different concrete qualities and structures. Hydroslide Effect - The Hydroslide Effect provides an optimal reduction of capillary absorption of water vs. other standard slurries.Available pack size: 5kg, 20kg, 25kg
CERESIT CR 65 requires pre-wetting of the substrate before application, avoiding formation of puddles. When waterproofing wall and foundation areas indoors or outdoors, e. g. in the case of rear penetration of moisture, pre-treat the areas with CERESIT CO 81 Silicifying Fluid. When waterproofing from negative side, the substrate must have sufficient technical strength.
CERESIT CR 65 is prepared with clean and clear water and is mixed until it becomes homogenous and free of lumps. The consistency of the mortar should be adjusted according to the application. The quantity obtained must be applied within 2 hours. The first layer will be applied consistently with a brush on the wetted substrate. When successive layers are applied, the next layer must only be applied when the previous layer is hardened, but still moist. Ceramic tiles, plasters or flooring can be applied on a layer of CR 65 after 7 days at the earliest from drying out too quickly, frost and precipitation.
Protect the waterproofing coat against damage. Do not cover it with gypsums materials. When covering the waterproofed substrate with tiles, always use a tile adhesive of minimum quality C. CERESIT CR 65 contains cement and produces an alkaline reaction with water. Therefore, protect skin and eyes.
CERESIT CR 65 is used:– for waterproofing against water loads– for waterproofing monolithic water tanks from inside as well as drinking water tanks and swimming pools with a water depth of ≤ 10 m– for subsequent waterproofing on the negative side– for filling drill holes/cavities in combination with the silicifying fluid CO 81- for improving concrete substrate resistance, even having different concrete qualities and structures- for prividing an optimal reduction of capillary absorption of water vs. other standard slurries (Hydroslide effect).
CERESIT CR 65 can be used on cementitious substrates that are ready for coating and non-shrinking, non-deformable, and salt-free e.g.:– structurally dense brickwork that is flush with the adjacent areas and has flush joints– concrete, cementitious plaster and composite screeds. In the case of possible mechanical loads operating on the slurry, such as pedestrian traffic, the CR 65 coating should be protected.Deformable substrates require the use of flexible materials, capable of covering cracks, such as: CERESIT CR 166. To immediately stop local water leakages, CERESIT CX 1 or CX 5 may be used.
Protect the waterproofing coat against damage. Do not cover it with gypsums materials. When covering the waterproofed substrate with tiles, always use a tile adhesive of minimum quality C CERESIT CR 65 contains cement and produces an alkaline reaction with water. Therefore protect skin and eyes. If contact occurs, rinse thoroughly with plenty of water. In case of contact with the eyes obtain medical advice.
