## Long description

Universal primer mc expert GRUNT UNIWERSALNY 5L is a 5-litre ready-to-use surface primer formulated to improve adhesion and prepare porous and absorbent substrates for subsequent coatings. Intended for general-purpose use on interior and exterior surfaces, this primer consolidates loose or chalky substrates, reduces uneven absorbency and creates a uniform base for paints, plasters and adhesives. It is suitable for use on walls, ceilings and façades prior to finishing work.
Advantages
This universal primer increases adhesion between the substrate and subsequent layers, which helps reduce peeling and flaking of finishes. It evens out surface absorbency, decreasing paint and plaster consumption and improving the appearance of the final coat. The formulation is designed for versatile application on a range of mineral and previously painted surfaces, providing deep penetration to consolidate porous substrates and limit dusting. The product is supplied in a convenient 5 L container suitable for medium-sized jobs.
Suitable for
 Preparation of interior and exterior walls and ceilings before painting
 Consolidation of porous, chalky or highly absorbent substrates
 Surface preparation before applying plasters, render or tile adhesives
 Priming façades and masonry to reduce uneven absorption
Key specifications
 Volume: 5 litres
 Type: universal surface primer for interior and exterior use
 Main function: improve adhesion and reduce substrate absorbency
 Suitable substrates: mineral surfaces, cement and lime plasters, gypsum-based plasters, concrete, previously painted surfaces
 Application: brush, roller or low-pressure spray
 Drying time: depends on temperature and humidity; typically touch-dry within a few hours under normal conditions
How to use
Ensure the substrate is clean, dry and free of loose material, dust, oil or mould. Stir the primer thoroughly before use. Apply the primer evenly using a brush, roller or low-pressure spray. On highly absorbent surfaces, a second coat may be applied after the first coat has dried to achieve uniform consolidation. Allow the primer to dry fully before applying paint, plaster or adhesive; drying time varies with ambient temperature and humidity. Clean tools with water immediately after use.
Usage recommendations
For best results, test the primer on a small area to confirm compatibility with the substrate and subsequent coatings. Protect adjacent surfaces and follow safety instructions on the product label. Store the container tightly closed in a cool, frost-free place.
