Cement-polymer waterproofing for concrete, brick, and stone surfaces
Cement-polymer waterproofing for concrete, brick, and stone surfaces
Material description:
"Megatron Coating" is a high-quality dry cement-polymer mixture specially developed for waterproofing various surfaces, including concrete, brick, stone, gypsum board, aerated concrete, foam blocks, and others.
This composition demonstrates impressive strength and resistance to water, weak acid solutions, alkalis, salts, and other aggressive environments.
Thanks to its unique properties, Megatron Coating creates a reliable barrier against moisture penetration, ensuring dependable surface waterproofing.
The polyamide fiber included in the coating provides exceptional strength and resistance to mechanical damage.

Application Recommendations:
Megatron Coating should be applied according to the manufacturer's technological regulations.
Before applying Megatron Coating, it is necessary to prepare the substrate.
Cleaning the substrate before applying waterproofing can be done using manual equipment. Mechanized tools such as water jetting units can also be used.
For manual cleaning, metal brushes or spatulas can be used to remove dirt and dust. If there are oil stains on the substrate, special solvents can be used to remove the dirt.
After completing the preparatory surface treatment, carefully check whether all cracks, joints, and openings are filled with Megatron Seam or Megatron Repair R-1 repair compounds. It is important that these fillers are applied evenly and well smoothed to avoid voids and defects in the waterproofing layer.
Next, before applying Megatron Coating, it is recommended to ensure that the surface is lightly moistened. This will promote better material adhesion and improve its adhesion to the surface.
During the mixing of Megatron Coating, it is important to accurately follow the proportions of water and dry components.
First, make sure that the dry Megatron Coating mixture is placed in a clean and dry container or bucket suitable for mixing. It is important that the container is large enough to allow thorough mixing of the components.
Add water gradually, following the ratio of 1 part water to 2 parts dry mixture. This means that for every one part of water, two parts of dry component should be added by volume. Start mixing using a mechanical mixer or spatula if mixing manually.
After adding water, thoroughly mix the material to ensure a homogeneous consistency. Then wait for 1-2 minutes before mixing the mixture again. If necessary, a small amount of water can be added, considering the application method and the desired consistency.
Carefully monitor the consistency of the mixture. It should be uniform, without lumps or undissolved dry particles.
After completing the mixing, leave the mixture for 1-2 minutes, allowing it to rest slightly. Before applying, mix the mixture thoroughly again to ensure a homogeneous consistency.
The first layer of coating is applied using a spatula or brush. It is important to evenly distribute the material and press it well onto the surface. The thickness of the first layer should not exceed 1 mm to avoid cracking.
After applying the first layer, allow it time to dry. The duration of this process depends on the humidity and temperature conditions of the environment.
After the first layer has completely dried, the second layer of coating can be applied. This is done in the same way as the first layer. It is recommended to work quickly as the Coating may start to harden.
Freshly applied coating should be protected from direct sunlight, rain, frost, and rapid drying. This will help prevent cracking and ensure proper drying of the material.
The application of the material should be carried out at a temperature not lower than +5°C.
Attention! All cracks, joints, seams, penetrations, and pressure leaks must be insulated using Megatron Suture and Megatron Plug.
Material consumption:
With a coating thickness of 2-3 mm, the consumption is 1.5-2.0 kg/m2
Storage:
The guaranteed shelf life is 12 months at a temperature from -20 to +60°C in the original factory packaging.
Safety measures:
When applying penetrating waterproofing, the following safety measures must be observed:
