Teknomer 640 is a modern polymer waterproofing based on polyurea, designed to create a durable, seamless and elastic waterproof membrane. The material can be applied manually without the use of complex specialized equipment, making it a convenient solution for waterproofing concrete, metal, wood and other substrates.

In this material, we will consider the main properties of Teknomer 640 , the method of application, adhesion to various surfaces, resistance to water and chemical influences, and also show the elasticity test, during which the elongation of the material at break is 800% according to ASTM D 412 .

What is Teknomer 640 polyurea?

Teknomer 640 is a two-component waterproofing material that, after mixing and application, forms a continuous elastic membrane without seams or joints.

Unlike traditional rolled waterproofing materials, the membrane coating follows the shape of the base and allows you to create a continuous protective layer even on surfaces with complex geometry.

The material can be used for waterproofing and protecting structures where water resistance, elasticity, and high adhesion to the substrate are important.

Polyurea without complex equipment

One of the features of Teknomer 640 is the possibility of manual application. This is the so-called cold polyurea, which does not require a special installation for hot spraying polyurea.

Before application, the two components must be mixed according to the manufacturer's technology. The finished material can be applied to the prepared base:

  • brush;

  • roller;

  • by airless application method.

Thanks to this, Teknomer 640 hand-applied polyurea can be used both in small areas and when performing waterproofing work on objects with complex geometry.

Waterproofing of concrete, metal and wood

Teknomer 640 has high adhesion to various types of substrates. According to the given characteristics of the material, the adhesion is 2 MPa to concrete, metal and wood. The material meets the requirements of the EN 1542 standard.

This allows us to consider Teknomer 640 as a universal solution for protecting various building structures: roof, terrace, balcony, foundation.

Before application, the surface must be properly prepared: cleaned of dust, dirt, weak areas and other contaminants that may negatively affect the adhesion of the waterproofing to the substrate.

Waterproofing of roofs, terraces and foundations with Teknomer 640 polyurea

Due to its elasticity, seamlessness and resistance to stagnant water, Teknomer 640 can be used in waterproofing systems of various structures.

Roof and attic waterproofing

The roof is constantly exposed to precipitation, temperature fluctuations and ultraviolet radiation. A continuous membrane allows you to create a seamless waterproofing layer on the prepared surface.

Terrace waterproofing

For terraces, protection against water penetration into the base is particularly important. Elastic coating can be used as part of a waterproofing system for terraces and other horizontal structures.

Foundation waterproofing

The foundation is constantly in contact with soil moisture and water. The use of an elastic seamless membrane allows you to create an additional protective layer for concrete structures.

Water and chemical resistance

Teknomer 640 is designed for use in conditions exposed to water and moisture. The material is resistant to salts, alkalis, acids and sulfates.

This makes polymer waterproofing relevant for various construction and industrial facilities, where surfaces may come into contact not only with water, but also with aggressive environments.

Main advantages of Teknomer 640

Key characteristics of the material include:

  • compliance with the ASTM D 412 elongation test method ;

  • elasticity up to 800% ;

  • adhesion to concrete, metal and wood - 2 MPa ;

  • compliance with EN 1542 standard ;

  • creating a continuous seamless waterproofing membrane;

  • possibility of application on horizontal and vertical surfaces;

  • manual application with a brush or roller;

  • possibility of airless application;

  • resistance to stagnant water;

  • resistance to salts, alkalis, acids and sulfates;

  • can be used on concrete, metal and wood.

How to apply Teknomer 640 polyurea?

Before application, it is necessary to properly prepare the base. The surface must be cleaned of dust, dirt, weak and fragile areas. Be sure to prime the base using epoxy primer Teknobond 120 , Teknobond 300 , Teknobond 307 or Teknobond 310. This will significantly increase the wear resistance of the base and the adhesion of  Teknomer 640 waterproofing to the base.

Next, the two components of the material are mixed according to the manufacturer's technology. After mixing, Teknomer 640 is applied to the prepared surface with the necessary tool - a brush, roller or airless application method.

Particular attention should be paid to the uniformity of application, layer thickness and proper preparation of the substrate. It is a comprehensive approach to preparation and application that allows you to obtain a reliable waterproofing system.

Teknomer 640 — modern elastic waterproofing

Teknomer 640 polyurea combines high elasticity, adhesion to various substrates, water resistance and resistance to chemical influences.

Thanks to the possibility of manual application, the material is a practical solution for performing waterproofing work without the use of complex equipment.

Teknomer 640 can be considered for waterproofing concrete, metal and wood, as well as a material for protecting roofs, terraces, foundations and other structures where a seamless elastic membrane is required.
