Cementitious sealing system
KRAFT HYDROGUARD ELASTIC is a 2-component brushable cement system, with high mechanical strength and elasticity, enriched with acrylic polymers, suitable for sealing and protecting surfaces from concrete, cement mortar, stone or brick. It is resistant to UV radiation and high reflectivity to sunlight. Can be applied to balconies, exposed terraces or not. Also in concrete walls, tanks, planters and surfaces that are subject to large temperature changes. It has zero water absorption and high mechanical strength. It provides excellent elasticity and the ability to bridge cracks and resistance to the contraction and expansion of the substrate. It has excellent adhesion to EPS, XPS, and all standard building substrates. Meets the requirements of standard EN 1504-2 as a surface protection material. It has been checked and meets the specifications of K.Y.A. Y2 / 2600/2001 for contact with drinking water.
To ensure good adhesion, the application surface should be clean, compact and free of dust, oils, lime, tar and loose elements. Work joints, poorly concreted nests, cracks and other large gaps must be repaired with suitable repair material, such as KRAFT STRONG REPAIR 84. Degreasing with metal surfaces with KRAFT BRUSH SOLVENT is recommended.
»Before applying the mixture on structural surfaces, wet the surface with water until saturation.
The mixture is prepared using an electric stirrer at low speed in the proportions described above. Pour the HYDROGUARD ELASTIC into a suitable empty container and add the HYDROGUARD ONE slowly as you stir. Stir thoroughly for at least 3-4 minutes. The mixture is ready for use when it becomes homogeneous without pellets.
After the preparation of the mixture, the additional addition of water is prohibited to correct the workability of the mortar. This will reduce its strength and increase its shrinkage.
»The application of the mixture on the substrate is done with a brush, roller or spatula in two layers crosswise avoiding the application thickness to be greater than 1mm per layer.
»In demanding points of the waterproofing, the use of anti-alkaline glass mesh KRAFT Hydroguard Net (75g / m2) is recommended to enhance the cohesion of the waterproofing layer.
»Mixture workability: 45min at 25 ° C.
»Minimum application time of 2nd layer: 2-5 hours in favorable drying conditions.
»Immediately after application the tools should be cleaned with warm soapy water or with detergent solution. When the material is completely hardened, it is removed mechanically.
»Stir the product well, before application and at regular intervals during application.
»Do not apply at temperatures below 10 ° C and above 35 ° C as well as at relative humidity above 80%.
»Do not apply in case of impending rain or under direct sunlight and wind.
