LUNIK · SYSTEM PREPARATION

Primers

Technical surface preparation to ensure adhesion, consolidation and protection of our systems. Professional solutions for every substrate and requirement.

The foundation of the system

Preparation that defines the result.

The right primer is essential for system performance and durability. It improves adhesion, regulates the substrate and helps achieve more stable, reliable finishes.

01

Secure adhesion

Improves the bond between the substrate and the coating, helping prevent delamination and adhesion failures.

02

Absorption control

Regulates substrate porosity to promote uniform application and more stable performance.

03

Substrate consolidation

Strengthens weak surfaces and helps reduce the appearance of cracks and premature substrate defects.

04

Long-lasting protection

Increases the chemical and mechanical resistance of the applied system, improving its long-term durability.

ACRYLIC PRIMERS
Water-based

PRIMER

PRIMER imprimación acrílica LUNIK

Water-based acrylic primer designed as a bonding bridge between concrete, cement mortars and gypsum.

  • High adhesion on both low- and high-absorption surfaces.
  • High penetration, ensuring effective bonding between both surfaces.
  • Helps prevent cracking caused by premature dehydration.
  • Can be applied on alkaline substrates such as lime, cement and gypsum.
Water-basedHigh penetrationInterior / exterior
With selected aggregates

PRIMERQUARTZ

PRIMERQUARTZ imprimación acrílica LUNIK

Water-based acrylic primer with selected aggregates, designed to act as a bonding bridge on concrete, cement mortars and gypsum.

  • Leaves no residual tack.
  • High adhesion on both low- and high-absorption substrates.
  • High penetration, ensuring effective bonding between both surfaces.
  • Facilitates application of the next layer thanks to its textured surface.
