Protect the foundations, cellars, the roof against moisture and prevent the flow of water from the pools the easiest way with an oil-impregnated waterproofing. These are specially designed mastics that are applied to a horizontal or vertical surface and after drying form a waterproof membrane a few millimeters thick on it.
The advantages are:
- resistance to low temperatures and heating( up to 500 degrees),
- high plasticity - all cracks will be protected, the coating can be applied to the surface of the most complex contours,
- no seams and joints through which water can leak,
- longevity of coating and no reaction with water,
- anticorrosive action - such waterproofing can cover pipes and metal structures,
- ease of application - enough brush or spatula,
- possibility nanSenia under the plaster, tile or other finishing materials.
Mastics are on bitumen, polymer, cement basis, and also combined, one- and two-component, providing cold or hot( with preheating the composition) application.
Products Ceresit
The German company Henkel offers the widest choice of coating agents for the waterproofing under the Ceresit brand name in the Russian market. All of them are distinguished by their ecological compatibility, high quality and ease of use.
Ceresit CR 90 Crystallizer is a penetrating waterproofing that is used for surfaces that are not prone to deformation. Can be used for indoor and outdoor work. In addition to water resistance, it has frost resistance and vapor tightness. Fills microcracks in concrete and strengthens its structure. Can be used for waterproofing containers with water for drinking and household needs. The coating dries out after 48 hours, and the next can be laid or applied after 3-5 days.
Ceresit CR 166 is a two-component elastic waterproofing that can be used on surfaces subject to slight stretching and compression, for example, foundations, basement floors, balconies, pools, terraces. A layer of waterproofing 1-3 mm thick is produced vapor-proof, inert to salts, alkalis, oils and most solvents.
Ceresit CR 65 is one of the most popular means for coating waterproofing in the Russian market. Like previous products, it is vapor-permeable, resistant to corrosive media and temperature extremes, can be used for indoor and outdoor applications. In private construction it is used for waterproofing pools, foundations and cellars, bathrooms, kitchens, caissons and other rooms and structures with high humidity. Forms a layer 2-5 mm thick, freezes completely in two days. This agent forms a hard coating, if elasticity is required, the Ceresit CС 83 elasticizer is added to it.
Ceresit CR 66 is a two-component waterproofing compound for the protection of structures, building structures and water tanks. Unlike CR 65, this is an elastic waterproofing.
Ceresit CL 51 is a one-component mastic for interior work. Forms an elastic coating 1-1.5 mm thick, which can fill cracks up to a thickness of 0.75 mm. It is usually used for processing floors and walls before laying tiles in rooms with high humidity: kitchens, bathrooms, saunas. Suitable for waterproofing in the installation of heated floors, the construction of swimming pools up to 5 meters deep.
Ceresit CL 50 is also a waterproofing mastic for covering surfaces in humid rooms, but already two-component. Its feature is fast solidification and the ability to lay tiles in a couple of hours after the coating.
Ceresit CP 42 is a one-component mastic, forms an elastic coating and can fill cracks up to 2 mm wide. Can be used to seal piles, foundations, roofs on concrete, brick, plaster. This mastic should be preferred in those cases where a long and intense exposure to water is expected.
Mastic Ceresit CP 48 "XPRESS" is characterized by superfast setting, only 90 minutes. It is based on a bitumen-latex mixture with a polystyrene filling. Elastic coating can cover cracks up to 5 mm and does not require thorough preparation of the surface before application.

Before applying any waterproofing agent, the surface must be cleaned, cement large cracks and remove the protrusions.
The number of layers and their thickness depend on whether the water will act on the surface from time to time or permanently, and what its volume will be at that. Specific values and details of the application need to be specified on the packaging, as they differ slightly from the different agents.
