GREINPLAST HW

Water hydrophobic impregnant

Used in the hydrophobisation of vertical construction material surfaces of the following types: walls made of ceramic and silicate brick, cellular concrete, gypsum blocks, clinker brick (including clinker joints), or concrete. The preparation may also be used to reduce the absorbability of thin-layer mineral plasters (including those applied in thermal insulation systems), cement and cement-lime plasters, claddings made of porous natural stones (such as sandstone), as well as of synthetic stones made of mineral binding agents. It is also useful in the impregnation of paving setts. The preparation has a superficial action, and does not cause adverse colour changes on impregnated surfaces.

Packaged in 5, and 1l containers.

Wykonanie

The preparation should be stirred or shaken before the application. During the application, use a roller, brush, a spraying device, or immerse in the working solution for ca. 5 minutes. On highly absorptive bases, repeat the procedure following the wet-on-wet” method, until the base is discernibly saturated with the solution. The full hyrophobisation effect, seen in the form of water beads present on the impregnated surface, is achieved after some 2-3 rainfalls.

Recommendations and remarks

New plasters should be impregnated 28 days after they are laid, whereas joint fillings should be impregnated after they have dried off completely. Do not impregnate in the rain. The temperature of the base and its surroundings during the application should be between 5°C and +30°C. Enclosed spaces should be aired until the characteristic smell is removed. Before works are commenced, carefully secure all surfaces that are not going to be impregnated. When they are soiled, clean it with white spirit. Application tools should be washed with water directly after the completion of works.
