Integral Water Proofing Compound - Versatile Application For Rcc And Plastering, Ideal For Water Tanks And Structural Members

Waterproofing for construction surfaces such as concrete and masonry

Hydro lastik is applied with a fibre type brush or by trowel when a smooth finish is required. For large areas Hydro Lastik can also be sprayed, being the recommended nozzle size 3-4 mm and spraying pressure between 3.5 and 5.0 bar. When sprayed, it is recommended to finish the fresh coat with a trowel to make sure that the whole surface is covered completely.Applytwo coats, using 1 aEUR" 1.5 kg/mA2 Hydro lastik per coat and allow a minimum of 16 hours and a maximum of 3 days between applications. Prior to application thoroughly wash down and saturate the surface, but do not leave free standing water. Thickness per layer should be 1 mm approximately, thereby being important to avoid very thin application or, on the opposite, a much thicker one. In those areas such as fissures, concrete joints and active cracks, once repaired and sealed. Place the mesh on a first coat of Hydro lastik with at least 20 cm wide of strip, and then apply a second coat of Hydro Lastik. Application conditions Optimum application temperature is between 10EsC to 25EsC. Do not apply below 5EsC or if lower temperatures are expected within the following 24 hours after application. Do not apply on frozen surfaces or if rain is expected 24 hours after application. Protect against quick drying by winds and direct sunlight with high temperatures, by fog spraying with water for two hours after application.Curing time required to put the product into service or to immerse it in water will depend on temperature and relative humidity conditions on site. Conditions in the range of 20EsC and 50% R.H will require a minimum of 14 days to ensure that the product has cured enough to be in permanent contact with water. Applications made at lower temperatures or sites without ventilation will require longer curing periods. After curing, wash the surface of Hydro Lastik with water before putting into service in permanent contact with water.
