MMA Primer for Damp Substrate

Product Introduction


Waterproofing wet concrete surfaces

Can be used on all kinds of concrete-cement-mosaic-tile and ceramic surfaces

Features / Advantages:

  • Special for concrete and wet surfaces
  • Very high adhesion to concrete, mosaic, stone, and ceramics
  • High penetration into concrete pores
  • High curing speed
  • Easy to use during installation
  • Economical

Storage Conditions

If the container is not opened and the original packaging of the factory is not damaged, the product can be stored for 6 months from the date of production in a dry environment and the original packaging at a temperature between 15 and 25 degrees Celsius.

Preparation Substrate

A concrete substrate must first be prepared mechanically and by means of submersible equipment until the top surface of the concrete, which contains the remaining cement and water and causes the surface to become alkaline (concrete sap), is removed and penetrates into the open pores of the concrete. Receipt.

Weak points of concrete must be removed and surface defects such as pits, holes, and cracks must be drained and then repaired. For this purpose, you can use the appropriate material for the repair.

It should be noted that all the dust on the surface must be removed before applying the products, for which it is recommended to use industrial vacuum cleaners with high suction power.

Technical Information

Appearance specifications:

  • Component 1: Liquid, colorless
  • Component 2: Mineral powder
  • Component 3: White powder


  • Component 1: 18.6 kg
  • Component 2: 10 kg
  • Component 3: depending on the temperature it varies.


Stir component 1 first before mixing. Then add component 2 to component 1 and stir for about two minutes at a speed of 400 rpm. Then add the appropriate amount of component 3 and stir for an additional time of 2 minutes. Avoid movements that cause air to enter the mixture while stirring. For mixing, you can use a mechanical mixer with a speed of 300 to 400 rpm.



MMA Primer| Damp Substrate

Solvent-free resin flooring primer based on methacrylate resin (MMA) is designed as three components and is suitable for wet concrete surfaces or substrates exposed to moisture leakage.

Like other MMA products, the curing reaction of this MMA primer is fast and it is widely used in applications that require a high speed of coating installation. The speed of installation and curing of this anti-moisture primer is such that one hour after the installation, the installation of the next layer of the flooring system can be started.

The unique features of this product include easy application, low viscosity, high penetration power, excellent adhesion to the substrate, and suitable physical and mechanical properties.

BASADUR® M 102 acrylate floor primer is specially designed for wet concrete surfaces or with latent moisture to seal them.

This product with excellent penetration power penetrates the concrete to a considerable depth and by blocking the pores in the concrete structure, it prevents the exit of water vapor or moisture in the concrete structure, which ultimately increases the life cycle of the flooring system.

To be more effective and create maximum adhesion to concrete surfaces, the importance of high-quality raw materials is very significant. Acrylate primer M102 made of the best material available in the market, with maximum adhesion to concrete, will be the interface between the substrate and the next layer. This product creates an interfacial area by creating a stronger bond and a strong connection, which is also resistant to environmental and corrosive attacks.

Fast curing reactions and short pot life have made it possible to apply the next layer in less time. This feature, along with easy use, is one of the most useful advantages of this product.
