How to Prepare Surfaces for Microcement

Microcement is one of the most versatile coatings – it can be applied over tiles, concrete, plasterboard, and even old paints. But proper surface preparation is 50% of success.

STEP 1: Assess the Surface

Ensure the surface is:

• Dry (moisture below 4% for mineral surfaces)

• Clean (free from grease, dust, oil)

• Stable (not crumbling or moving)

STEP 2: Repair Cracks

All cracks and holes must be filled with suitable filler. For larger damage, cement mortar can be used.

STEP 3: Priming

PRIMER Q is the first step. It ensures adhesion and evens out surface absorbency. Apply with a roller and allow to dry for 4-6 hours.

STEP 4: When is the Surface Not Suitable?

❌ Wood parquet (unstable)
❌ Linoleum (poor adhesion)
❌ Damp surfaces (must fix moisture source first)
