Application
FAST GRUNT U is a ready for use preparation for priming and leveling out the absorptivity of different surfaces. It is perfect to be applied on concrete and gas-concrete bases, as well as on gypsum and gypsum-cardboards, cement and cement-lime plasters. It can be used both inside and outside buildings. It makes a perfect basis to be then treated with paints, putty, adhesive and leveling out plasters as well as to be covered with wallpapers or cement flooring. It increases the adhesion of finishing materials and lowers material dusting. One of its extraordinary features is the fact that it inhibits the growth of mould and microorganisms on the primed bases.
Characteristics
FAST GRUNT U does not contain dissolvents, it is non-flammable, water-diluted, odour-free, environmentally-friendly and can be applied both inside as well as outside buildings. The concentrate makes the base faster, regulates the base absorptivity process and lowers the use of paint. After drying up it is completely transparent and steam-permeable. It contains an agent preventing the growth of mould and microorganisms.
Preparation of the base
FAST GRUNT U can be applied on a base which is dry, free from any impurities such as dust, wax, grease, oil, lubricants and non-permeable paint coats. In case there is mould, they should be first treated with FAST MUR.
Instructions
The preparation can be applied with a brush or a roller onto the base with the temperature of from +5oC to +25oC. In case of a very absorptive, worn out or pouring out base it is recommended to prime it first with a deeply penetrating preparation FAST GRUNT G. The base primed with FAST GRUNT U is ready for further working after approximately 24 hours after priming. In case there has been a skin contact, rinse with water.
Efficiency
The use of the emulsion depends greatly on the degree of absorptivity of the base and is approximately 0,05 – 0,25 kg/m2.
Storage
Store in tightly closed packages at the temperature of from +5oC up to +25oC.
Suitability for use: 12 months.
