Fast Grunt S

water glass based primer for silicate paints

Usage

FAST GRUNT S is designed for priming mineral surfaces such as: cement, cement-lime plasters and thin-layer mineral plasters. It is also used for priming raw surfaces made of concrete, as well as bricks, blocks, hollow blocks and other such ceramic or lime-sand materials. It may also be used as a thinner for silicate paints.

Properties

FAST GRUNT S strengthens the surface and levels its absorbency. It facilitates the application of paint coatings and improves their adhesion. It chemically reacts with the surface, penetrating its structure. It is colorless after drying. It is only intended for outdoor use.

Surface preparation

The surface should be dry, stable, strong and free from layers that may weaken adhesion, especially dust, dirt, wax and grease. Old, poorquality paint coats and other layers with poor adhesion to the surface, as well as coats made of dispersion paints should be carefully removed to obtain a clean mineral surface, minor damage and cracks should be repaired and smoothed. New plasters can be primed after they have dried, but not earlier than after 3 days.

Preparation and usage method

FAST GRUNT S is a ready-to-use preparation. Mix the contents of the package before use. The primer must not be diluted. The primer should be evenly applied to the surface with a brush or roller. Prime highly absorbent surfaces again after 2-3 hours. Apply the paint on the primed surface after at least 24 hours. Works should not be carried out during rainfall, strong wind and high sunlight of the primed surface. Protect against rain, frost and quick drying. Tools should be cleaned with clean water immediately after use, before the primer dries. It is recommended to use gloves, glasses and protective clothing.

USE

Depending on the type of substrate, Fast Grunt S consumption is from 0.08 to 0.1 l / m².
