Primer (deep-penetrating) mc expert MC-500-0110, 1 L

Deep-penetrating primer mc expert MC-500-0110, 1 L is a single-component, water-based solution formulated to consolidate porous and highly absorbent substrates prior to finishing works. It reduces surface absorbency and improves adhesion of paints, plasters and adhesives on concrete, cement, gypsum and masonry. The product is suitable for both interior and exterior applications where deeper penetration into the substrate is required to stabilise loose particles and create a uniform base for subsequent coatings.

Advantages

The primer provides deep penetration into porous substrates to strengthen and stabilise surfaces, which helps prevent uneven absorption of finishing materials. It improves adhesion of decorative paints, thin-layer plasters and tile adhesives, and helps reduce overall material consumption by evening out base porosity. The water-based composition allows for easy application and low odour, and the 1 L packaging is convenient for small- to medium-scale renovation and finishing tasks.

Suitable for

• Consolidating interior and exterior concrete and cement surfaces
• Priming gypsum boards, plaster and render before painting or coating
• Preparing masonry and brickwork prior to plastering or tiling
• Stabilising unevenly absorbent substrates to improve adhesive performance

Key specifications

• Form: water-based, single-component primer
• Volume: 1 litre
• Application: brush, roller or low-pressure sprayer
• Drying time: typically surface-dry within 1–2 hours depending on temperature and humidity
• Coverage: depends on substrate porosity; refer to substrate condition for estimated consumption
• Use: suitable for interior and exterior use on concrete, cement, gypsum and masonry

How to use

Ensure the substrate is clean, dry and free of dust, grease, loose particles and surface contaminants. Stir the primer thoroughly before use. Apply evenly with a brush, roller or low-pressure sprayer, working from top to bottom and avoiding puddling. Allow the primer to penetrate and dry according to ambient conditions; ensure full curing before applying subsequent plasters, adhesives or paints. On highly absorbent substrates a second coat may be applied after the first coat has dried. Clean tools with water immediately after use.

Usage recommendations

For best results, test the primer on a small inconspicuous area to assess penetration and coverage. Observe recommended drying times and apply finishing materials only to fully dry, stable surfaces. Store in a cool, frost-free place and protect from direct sunlight. Keep out of reach of children.
