Product description

Acryl based fine-molecular primer containing yellow dye tracer.


Application areas

On absorbent surfaces use 1 part mira 4180 primer diluted with 3 parts water, for less absorbent substrates 1 part primer with 2 parts water. Use as a concentrate on wooden surfaces to ensure adhesion between the substrate and the subsequent layers , such as screed, waterproofing or tile adhesive.


Type of substrate

mira 4180 primer is used on concrete, gypsum and other mineral substrates, as well as wood and gypsum board.


Pre-treatment of substrate

The substrate must be sound and free from dirt, oil, grease, paint, glue residues, and loose particles. Holes cracks or similar must be repaired with a compatible leveller/filler (water proof).



The substrate must be dry enough to absorb the primer. Porous substrates, such as concrete, lightweight concrete, plaster or masonry must be primed with 1 part mira 4180 primer diluted in 3 parts water. Less porous substrates must be primed with 1 part primer diluted in 2 parts water. Non-porous substrates, such as paint and ceramic tiles must be primed with concentrated primer. To achieve even better adhesion, dry cement powder can be dusted on top of the primer. Wooden substrates must be primed with concentrated primer.
