Product description

A modified polymerization technology, resin based primer increasing hardiness and adhesive strength between the surfaces and cement, especially gypsum based plaster applied onto even concrete surfaces, walls and ceilings.

Fields of Application

This product can be applied in the following areas:

  • indoor areas, vertical surfaces and ceilings;
  • applied as liquid primer creating two-way bonding in order to increase adhesive strength between even surfaces and gypsum, gypsum cement and cement based plasters;


  • Ready for application;
  • Increases adhesive strength between cement and especially gypsum based plasters and molded concrete surfaces;
  • Does not contain detergents;
  • Prevents fast loss of water in cement and especially gypsum based plasters;
  • Increases useful life of plasters;
  • Saves material consumption.

Application procedures

Preparation of the surface. Please pay attention to the treated surface: it should be healthy, dry, hard, dust-free, clean, and should have required dimensions. The surface should be totally free of fat, rust and paraffin residues deteriorating adhesive force; there should not be any small defects.

Preparation of the mixture. Pour 10 kg of PARAKONTAKT product into a designated bucket, and gradually add water  in the proportion of up to 1% of the product weight. Prepare this mixture for 3-5 minutes using a 400-600 RPM mixer till the solution is entirely homogeneous.

Application. Apply the mixed and ready to application product onto the preliminary prepared surface using paddle roller. It is necessary to test the absorption ability of the surface prior to application of the PARAKONTAKT product onto the surface. The cement based and especially gypsum based plasters can be applied onto the surface treated with the PARAKONTAKT product in 24 hours after its hardening.

Recommendations. If at the time of the PARAKONTAKT product application the ambient temperature exceeds the limits of +50C - +300C range, then the required temperature level should be provided. The product should not be used on external surfaces. It is important to keep the primer in clean conditions both during application, and after application. The PARAKONTAKT product is not suitable for application in the areas of high humidity (i.e. bath houses, saunas, swimming pools, etc). During application the product should be frequently mixed.


The PARAKONTAKT product consumption is 150-250 g/m2, depending on water absorption properties and smoothness of the surface. The consumption of the product mixed with water is 210-375 g/m2.

Shelf Life and Storage Method

  • The product can be stored in original buckets in cool and dry conditions, protected from freezing. For the short storage period the buckets may be placed on wooden racks one upon the other in three layers, and in the time of application the bottom layer buckets should be used first.
