More than 1000 items can be found in the company's product range, which allows us to solve the most complex problems in construction. As an example, waterproofing “Mapey”, which is intended for professional use, can be considered. Materials for waterproofing this brand are presented:
- epoxy waterproofing;
- bituminous waterproofing;
- waterproofing cords and tapes;
- polyurethane waterproofing;
- cement-based waterproofing.
Application area
Waterproofing "Mapey" has proven itself in the construction of various structures, swimming pools, as well as residential and industrial buildings. The materials can be used for indoor and outdoor insulation of basements, foundations, bathrooms and shower rooms, as well as communication channels, balconies, showers and terraces.
The material acts as a reliable protection for various structures such as plaster, drywall sheets and ceramic tiles. Waterproofing "Mapey" has found its wide distribution in the field of industry, it is used to insulate the concrete surfaces of tanks, transport structures, chimneys, concrete and brick containers, as well as tanks for drinking water. The described waterproofing is able to perfectly protect concrete that has cracked during shrinkage. This can happen as a result of water infiltration or under the influence of aggressive agents, as well as in contact with sea water and salt.
Waterproofing Composition
“Mapey” waterproofing is a two-component composition, among the ingredients of which are component A and liquid component B. In the first case, it is a mixture of fine-grained aggregate, special additives and cement binder, while in the second it is a synthetic water-dispersion polymer. To obtain a homogeneous mass, the components must be mixed, and the solution can be applied to vertical and horizontal substrates using a spatula.
The synthetic resins in the composition are of excellent quality, so they retain water resistance and elasticity under arbitrarily difficult conditions, which is true even if the pressure reaches 1.5 bar.
Featured Materials
The waterproofing waterproofing "Mapey" has high elasticity, excellent adhesion to various surfaces, including:
- ceramics;
- masonry;
- marble;
- concrete.
These characteristics, combined with resistance to solar radiation, allow the use of the material even in industrial regions, the conditions of which are characterized by air pollution. Quite often, the waterproofing of this manufacturer is also used in coastal areas, the air of which contains a large amount of salts.
Varieties of waterproofing "Mapey"
Waterproofing "Mapey" two-component is characterized by the absence of shrinkage, it can be used without first applying a primer. The material is presented in two varieties, each of which has a special purpose. If the surface will be exposed to negative or positive effects of water, then work should be carried out using the Mapelastic Foundation. But for substrates that are under the influence of positive water pressure, Mapelastic Smart is usually used.
Recommendations for use
In order to achieve a positive result when using the described waterproofing, it is recommended to apply it with a thin layer up to 2 mm. If you increase this indicator, then elasticity may be impaired. Do not start work if the thermometer has dropped below +8 ° C.
It is not necessary to add extraneous ingredients to the solution, such as water or cement, and after application, the layer must be protected from water. Such recommendations must be followed during the day. Mapey is a waterproofing that can be used to work with flat roofs or terraces.
The nuances of using
If it is not planned to lay the tiles on them, then the surfaces should be supplemented with deflectors, one will be enough for 25 m 2 . However, the final amount will depend on the level of humidity at the surface. These actions are recommended for waterproofing surfaces that are highly absorbent. Among them, one can distinguish screeds facilitated by expanded polystyrene or expanded clay.
Application technology
Waterproofing "Mapey", the use of which should be carried out according to the instructions, is applied to previously prepared bases. Care should be taken that the surface does not have damage and cracks, is durable and clean. Before starting work, the base is moistened. When preparing the solution, the liquid component must be placed in a container by adding a dry ingredient. The composition is mixed using a mechanical stirrer, which is set at low speed. This condition is important to prevent saturation of the solution with air bubbles.
The mixture is mixed for several minutes until smooth, the powder should not precipitate at the bottom of the container. Before filling the pump with a solution, it is important to make sure that there are no lumps in it and it is completely homogeneous. Application can be carried out using a spray gun or work manually. Waterproofing will remain viable for 60 minutes. All subsequent layers should be applied only after the previous ones have dried, the layer thickness should not be more than 1 mm.
Additionally, Mapelastic waterproofing
Recently, Mapelastic waterproofing has become increasingly popular. "Mapey" is a two-component waterproofing, which can be purchased for 4,500 rubles. For this cost, you get 32 kg of material that is resistant to anti-icing salts, CO 2 , chlorides and sulfates. It is necessary to use the material for processing retaining walls and precast concrete elements that will be buried in the ground.
Quite often, the material is used for surfaces that have been plastered with gypsum and cement based compounds. Suitable material for waterproof plywood, as well as drywall. Two-component waterproofing “Mapey” is applied in 2 layers. Rostov-on-Don offers this material at the aforementioned price.
In the first layer, it is necessary to lay a reinforcing mesh, which is resistant to alkali. The second layer can be applied after the first has dried. In the places of interfacing, a waterproofing tape is glued, while in places of the outlets of pipes and drains - waterproofing adhesives. In the first case, we are talking about connecting the wall to the floor or wall to wall. The reinforcing elements after drying of the first layer are covered with a second layer of material. Once the surface is dry, you can begin laying tiles.
The waterproofing "Mapey" is a product for professional use. Mapelastic has the form of a gray powder, the specific gravity of which is 1.4 g / cm 3 . The characteristics are calculated for the use of waterproofing at a temperature within +23 ° C, while the relative humidity should be 50% or less.
For mixing, it is necessary to use a ratio of 3 to 1 (respectively, components A and B). Thus, for 24 kg of the first ingredient, 8 kg of the second will be needed.
It is recommended to use the composition at a temperature of +5 to +35 ° C. After 28 days at +23 ° C, the mixture is able to stretch elastically. In this case, the humidity should not fall below +50%.
If you plan to carry out manual application of the material, then the consumption will be 1.7 kg / m 2 . With a machine method, the flow rate increases to 2.2 kg / m 2 . “Mapey Elastic” - waterproofing, which should not be applied in a layer thicker than 2 mm in one layer. When using waterproofing to repair substrates that will be in contact with drinking water during operation, after hardening the material must be washed several times with warm water, the temperature of which will be 40 ° C.
Additional application guidelines
If you plan to protect concrete with waterproofing, then its surface must first be checked for strength. The base is cleaned of the remains of cement milk, and dust can be disposed of manually or mechanically. If there is a substrate that is contaminated with grease or oil, you can use sandblasting or hydraulic washing to clean.
Rust must be well removed from the surface, and damaged parts are pre-repaired with special compounds. If you have to work with surfaces that absorb water well, then before starting work, the base must be saturated with liquid. Waterproofing "Mapey", the mesh with which is used, should be applied to surfaces previously cleaned of paint, grease and wax, and if we are talking about cement plaster, then it should be kept for a week for each centimeter of thickness.
After completion of work, contaminated tools are washed in water, this must be done before the composition hardens. If all this has already happened, the working tool is cleaned mechanically. Manual preparation of the composition is not recommended. This is especially true if large surfaces are to be treated.
Conclusion
When it is planned to work by the method of manual waterproofing, a smooth spatula should be used to form the first layer. The second layer should be applied so that the total thickness does not exceed 2 mm.
When processing balconies, terraces and swimming pools, a fiberglass mesh is installed in the fresh first layer. The dimensions of its cells should be as follows: 4.5 x 4 mm. This mesh is recommended for application if there are large cracks on the surface, as well as if the base will be subjected to intense loads.
