Description

Smartscreen HC20 H rigid waterproofing is a ready-to-use dry mix manufactured on the basis of cement and modifying additives.

The waterproofing material is environmentally friendly and does not contain any harmful impurities that have a negative impact on human health. Fully compliant with hygienic standards that are valid in the territory of the Russian Federation.

The product is manufactured from environmentally compatible raw materials in compliance with the technical specifications of the manufacturer.

Advantages

  • High ability to resist weathering
  • Good resistance to high mechanical loads
  • High resistance to the impact of salts
  • Contact with drinking water is permitted

Scope of application

This product is recommended for non-deformable mineral substrates. Smartscreen HC20 H rigid waterproofing is designed for waterproofing of foundations of buildings, facades, plinth walls, basements, balconies, terraces, walls, and floors in humid premises.

It is used for waterproofing pools, tanks, and reservoirs, including drinking water tanks and reservoirs. It is especially recommended for the restoration of old buildings. Smartscreen HC20 H can also be used to protect hydraulic engineering and water treatment facilities. Fitness for internal and external work.

Brief instructions for the implementation of remedial work

Substrate preparation

The substrate must be clean and stiff. Concrete and masonry must be cured for no less than 3 months; plasterwork and screed, for no less than 28 days. Prior to applying the waterproofing finishing, it is necessary to clean the surface from crumbling elements, grease stains, and other contamination that prevent adhesion of the material to the surface. Cold joints and cracks must be prepared in compliance with the working method. Corner areas must be rounded off by means of cement-mortar rounding-off shoulders (angle fillets with a radius of no less than 3 cm); on quoins, bevel edges at the angle of 45° must be made.

Mortar preparation

In order to prepare the mortar, the contents of the bag must be poured into a tank with clean water at a rate of 0.18-0.20 liter per kg while constantly mixing. The mortar must be mixed either mechanically (with the use of an industrial-grade mixer) or manually. The mortar must be set aside to cure for 3-5 minutes and then re-mixed. Then, the mortar is ready for use. The mortar must be used within 1 hour from the moment of pre-mixing with water. In case of increased viscosity of the mortar in the tank (within the life time of the mortar), it is necessary to remix the mortar without adding water. Only clean capacities, tools, and water must be used for the preparation of the mortar.

Application

The prepared solution is applied with the use of a brush in 2-3 layers. Each subsequent layer must be applied depending on external conditions but not earlier than 1 hour after the previous layer. The recommended thickness of the waterproofing coating is 3-4 mm. In the course of implementation of the work and in the next two days, the air and the substrate surface temperature must be between +5 °C and +30 °C. In the process of hardening (at least, 24 hours), the surface must be kept moist and protected from rain, direct sunlight, and frost effect. After 3 days following the installation of the waterproofing layer, additional layers may be installed.
