"Hyperdesmo" - waterproofing, which is a mastic, completely ready for use. It has a liquid consistency and is made from hydrophobic polyurethane resins. On the surface after processing with mastic, a continuous membrane forms, which acts as a protection against exposure to water. Waterproofing is universal, because it can be used for internal and external works.
Areas of use
"Hyperdesmo" - waterproofing, which has outstanding technical characteristics and is easy to use. The scope of this material is quite wide. It is possible to apply waterproofing on:
- flat roofs ;
- pools;
- old waterproofing from bitumen;
- tile;
- polyurethane foam;
- terraces;
- balconies;
- basements;
- tunnels.
Waterproofing is also used as anticorrosive protection of reinforced concrete structures. It is important to remember that mastic should not be applied on a not very strong foundation.
Basic properties
Hyperdesmo is a waterproofing that is resistant to abrasive substances, has high heat capacity and vapor permeability, eliminates the formation of cracks when exposed to high and low temperatures, is resistant to ultraviolet radiation, can be used as anti-corrosion protection and for the formation of a seamless membrane on any area.
After creating a waterproofing layer between the coating and the base, vapor pressure is not created. Under different conditions, the material retains elasticity, is able to undergo various climatic influences and maintain resistance to microorganisms. "Hyperdesmo" - waterproofing, which undergoes the impact of:
- oils;
- salt water;
- acids;
- alkalis.
If necessary, cladding and screed can be equipped with a waterproofing coating. After completion of the polymerization step, the material loses its toxicity. For decorative coatings, you can find this mastic in different shades.
Surface preparation for waterproofing
Waterproofing "Hyperdesmo", the instructions for use of which are described below, should be applied to a previously prepared surface. The base should be dusted, leveled, dried, and made sure that there are no peeling and residues of fat, oil products and oils on it. The surface is recommended to be treated with degreasing agents.
If the mastic is applied under the tile, then the presence of small irregularities and cracks is allowed, in all other cases, such errors are processed by the sealant. Hyperdesmo polyurethane waterproofing should be applied to a small area to check compatibility, which is true if the surface to be treated is made of concrete with the addition of waterproofing additives. This is especially true when building pools. If incompatible additives are present in the material, this will cause a decrease in adhesion or inability to polymerize.
Instructions for use
The viscosity of the mastic will increase if the thermometer drops below +15 ° C. In order to reduce viscosity, the composition should be kept for 24 hours in a warm room. As an alternative solution, you can use the method of applying a water bath for heating.
Waterproofing "Hyperdesmo Classic" is implemented in a completely finished form, when using it there is no need to add solvents. Before application, the composition is mixed with a low-speed mixer, which should be supplemented with a spiral nozzle. It is necessary to carry out these works until a homogeneous mass is obtained, it usually takes about 4 minutes. Application of the mixture is carried out by a roller, the use of foam must be abandoned. You can use a rubber spatula, brush or airless spray equipment for these purposes, which is convenient for processing large areas.
Methodology
The waterproofing must be done in two layers, each of which must have its own color. This will guarantee visual control. Waterproofing "Hyperdesmo", the consumption of which is 1.5 kg / m 2 when applied in two layers, must have a thickness in the range from 1 to 1.5 mm. It is important to ensure that the thickness of each layer is 0.4 mm or more. The maximum value is 1 mm. If the layer is thicker, then you will encounter slow polymerization and deterioration in the quality of the mastic. In this case, bubbles may appear.
Recommendations of a specialist on the use of mastic
The application of the second layer should be carried out only after the complete hardening of the previous one. This can take from 6 hours to a day, which will depend on the air temperature and its humidity. If the base will be subjected to heavy loads, then it must be reinforced with a fiberglass mesh, which fits in 1 layer until polymerization.
It is important to eliminate contamination of the first layer. Experts indicate that distortions and influxes of mastic are excluded. The surface is ready for use 24 hours after completion of work. To increase abrasion resistance, anti-slip properties and wear resistance, the last layer must be sprinkled with dry quartz sand, and then coated with a layer of varnish. The latter measure will increase the mechanical and chemical resistance.
If it is planned to waterproof containers for drinking water, then after polymerization they are filled with cold water and kept for one day. Only after such a procedure can the tank be used for its intended purpose.
Terms of work
Waterproofing "Hyperdesmo Classic" (gray, 25 kg) should be applied at temperatures ranging from +5 to +35 ° C. It is important to exclude precipitation. Do not store mastic for more than 10 hours in an open jar, because in this case the polymerization process will begin.
It is recommended to store the material at a temperature range ranging from 10 to 25 ° C. It is important to consider that mastic is flammable, therefore, when carrying out work it is forbidden to smoke and use open flame. One-component mastic is convenient to use, with its help you can achieve the formation of a seamless coating that is resistant to adverse factors.
Why choose Hyperdesmo waterproofing?
Polyurethane mastic under the Hyperdesmo brand has been known to Russian consumers not so long ago. It appeared on the market about 12 years ago. But today waterproofing is quite popular, because it has many advantages. For example, the process of creating a waterproofing layer is quick and easy.
The material consumption is minimal, and the volume of the composition during polymerization does not change. Mastic is characterized by high elasticity even at low temperatures. If you use the method of airless spraying, then in one shift it is possible to process an area of up to 500 m 2 .
Conclusion
To carry out waterproofing works, you can also choose Hyperdesmo mastic, which perfectly copes with the effects of the environment. According to manufacturers, the material is durable and ready to serve for up to 30 years. You can count on environmental safety as well as ease of application.
