Application
FAST GRUNT S under silicate paint is designed for priming mineral bases such as cement, cement-lime, and thin-coat mineral plasters. It can also be used to prime crude surfaces made of concrete, also bricks as well as of blocks, hollow bricks and other ceramic and lime-sand materials.
It is also used as a diluent of silicate paints.
Characteristics

FAST GRUNT S under silicate paints makes the base stronger and its absorptivity even. With the use of this agent paint coats are easier to make and their adherence gets improved. It reacts chemically with the base and penetrates its structure. After drying up it is colourless. It can be used both indoors and outdoors.

Preparation of the base
The base should be dry, stable, fast and cleaned of any residues which might weaken the adherence of the prime, such as especially dust, dirt, wax and grease. Old weak quality paint coats and other coats of weak base adherence, as well as dispersion paint coats should be thoroughly removed in order to achieve a clean mineral base. Small defects and cracks must be repaired and filled. Fresh, new plasters can be primed after drying up, however not earlier than 3 days after plastering.
Instructions
FAST Grunt S is a ready for use product. Mix thoroughly before applying. It mustn’t be diluted. The priming agent must be applied evenly onto surfaces with a brush or a roller. Bases with high absorptivity should be primed again after 2-3 hours. Wait at least 24 hours to apply paint onto the previously primed base. Do not work when it is raining, windy or when the base to be primed is exposed to direct strong sunlight. Protect from rain, frost and quick drying up. Tools must be cleaned with clear water, just after using before the prime dries up. Use of protective gloves, goggles and wear is advisable.
Efficiency
Use of the priming agent depends of the base absorbability and is 0,08 – 0,10 kg/m2
Storage
The prime coat should be stored and transported in packages tightly close at the temperature of from +5oC to +25oC.
