In the construction of any object requires the execution of waterproofing works. This is a very important and responsible process, requiring care and attention to detail. Waterproofing in the future will save not only your money and time! Neglecting these processes can lead to very serious consequences. The result may be the formation of mold, mildew, corrosion of metal structural elements, damage to the layer of plaster or panels, and in some cases loss of load-bearing function of the whole structure.
What material to choose? Today the market offers many options of materials for waterproofing:
- mix one- and two-component. Which in turn are divided into penetrating, elastic, booking etc
- mastic bitumen, bitumen-rubber, thin, thick, water-based, solvents , etc.
From components depends on the application field and purpose. The issue price also depends on the composition of the selected material. While trying to figure out what is what, a person unrelated to the construction of "head will spin".
In this article, we will discuss in detail the two-component polymer-cement compounds for waterproofing, which proved themselves as high-quality and reliable materials, this Teknomer 200 EX, Teknomer 200 . Their application, advantages and how to apply.
Teknomer 200 EX, Teknomer 200 is a two component waterproofing cement and acrylic based with special additives. Used inside or outside the structures of porous materials (brick, stone, concrete blocks, limestone can be applied over plaster, screeds). Suitable for horizontal and vertical surfaces.
The advantages of two-component polymer-cement waterproofing:
- Environmentally safe, can contact with drinking water
- The coating is vapour permeable, so allows the concrete to "breathe"
- Due to the elastic properties, the coating is able to block the cracks up to 4 mm
- High resistance to freeze-thaw
- Penetrates deep into concrete and masonry base
- To apply the composition is simple, the requirement for surface moisture minimum
- Resistant to negative and positive water pressure
- Suitable for both horizontal and vertical surfaces
- Does not shrink
Applications:
- Waterproofing of foundations, tunnels, shafts, which are exposed to positive and negative pressure of the groundwater
- A building structure under dynamic loads
- Waterproofing canals, dams, water systems, water treatment structures, swimming pools, potable water tanks, and bridges
- Waterproofing balconies and terraces
- Waterproofing indoors under tiles in bathrooms, kitchens and other wet areas
- Internal and external waterproofing of new and old structures exposed to aggressive environments
The application of polymer cement waterproofing:
Important!!! Before applying the mixture, you must prepare the surface, clean it from dust, dirt, oil, and debris. The cracks and the seams are embroidered and tightly filled repair compounds, it is recommended to use a repair compound Teknorep 300, Teknorep 300 EX. If you have an active water leak, it needs to be addressed through Teknoplug.
- Mix the two components.
- Pour the liquid component into a clean container, proportioning, slowly add the powder part, and mix thoroughly with a mixer at low speed (500 rpm) for 5 minutes. Allow the solution to stand for 3 minutes, then continue mixing until a homogeneous mass.
- Next, the prepared solution Teknomer 200 or 200 Teknomer EX should be applied in 2-3 layers with a brush or spatula, thoroughly rubbing into the surface, leaving no gaps (the second layer is applied in the vertical direction of application of the 1st layer!).
- The corners and joints on the surface should be sealed elastic adhesive tape for sealing construction joints Teknomer Pah Band 120/70. After application the surface should be protected from direct sunlight, frost and wind not less than 1 day.
