Primer (grond) mc expert MC-500-0010 1L — universal surface primer

mc expert MC-500-0010 is a 1 L universal surface primer formulated to prepare and consolidate a wide range of building substrates prior to finishing. Supplied in a 1-litre container, this primer reduces substrate absorbency, evens out porosity variations and improves adhesion of paints, plasters and tile adhesives. The product is suitable for both interior and exterior applications where a general-purpose primer is required to create a uniform base coat and enhance the performance of subsequent finishes.

Advantages

The primer improves bond strength between the substrate and finishing materials, helping paints and plasters to adhere more evenly. By reducing and equalising absorbency it prevents excessive suction in porous surfaces, which can lead to uneven coverage and increased material consumption. Its universal formulation makes it compatible with a wide range of common construction substrates and finishing systems, and the 1 L packaging is convenient for smaller repair jobs or sample areas.

Suitable for

• Interior walls and ceilings before painting or plastering
• Exterior masonry and rendered surfaces prior to finishing
• Preparation of plasterboard and cement-bonded boards
• Priming porous or uneven substrates to improve adhesive performance

Key specifications

• Volume: 1 litre container
• Type: universal surface primer for consolidation and adhesion improvement
• Application areas: interior and exterior use
• Function: reduces absorbency and evens substrate porosity
• Compatible with: paints, plasters and tile adhesives

How to use

Ensure the substrate is clean, dry and free from dust, loose particles, grease and other contaminants. Stir the primer thoroughly before use. Apply evenly with a brush, roller or low-pressure sprayer, respecting recommended coverage rates for the substrate porosity. Allow the primer to dry fully before applying finishing coats; drying time depends on temperature and humidity. For highly absorbent surfaces a second priming coat may be required to achieve uniform absorption.

Usage recommendations

Use in well-ventilated conditions and follow standard safety guidance for handling waterborne primers. Store the product upright in a cool, frost-free place. Test compatibility with specific paints or plasters on a small area if unsure. Dispose of any unused product and empty containers in accordance with local regulations.
