Planiseal WR 100 | Silane Sealer

 

 

Substrate preparation Concrete must be well cured, sound, and clean and free of all traces of oil, grease, cement laitance, old paint and any other material or substance that could prevent Planiseal WR 100 from penetrating into the concrete. When treating old concrete, the cleaning method adopted depends on the type of dirt or stain to be removed. Hydroblasting with cold water is generally sufficient to open surface pores and thus facilitate the penetration of the product. Hydro-blasting with hot water is particularly effective in removing oil and grease. If there are no stains or dirt, to blow the surface down with compressed air is usually sufficient. Before applying Planiseal WR 100 wait until the surfaces are dry. Preparation of the product Planiseal WR 100 is supplied ready-mixed and must not be diluted with water or solvent. The product must be well mixed before use, in order to ensure it is perfectly blended. Application of the product Make sure the surface of the concrete is not frozen and that rain or a drop in temperature to below +5°C is forecast for at least 12 hours after application. The effectiveness of Planiseal WR 100 depends on its penetration depth and this in turn depends on the type and absorbency of the concrete. The product may be applied by lowpressure airless spray on large surfaces or with a roller for smaller areas. It is recommended to apply two coats of product to get a more uniform distribution. The second coat may be applied while the first coat is still wet, as long as it has penetrated into the substrate. Remove any excess product with a roller while still wet. The surrounding temperature, the temperature of the substrate and the absorbency of the substrate will all affect the product’s drying time. Do not apply Planiseal WR 100 on substrates that are not sufficiently cured. Areas that are still moist could limit the spread of the product deep down into the concrete.
