Microcement for floors and walls

Microcement is a continuous coating 2 to 3 mm thick that is applied over what you already have—tiles, terrazzo, concrete, or plaster—without the need for construction work or debris. It creates a seamless surface on floors, walls, bathrooms, countertops, and stairs.

What a microcement system really includes
It's not a product, it's a system. Buying only the microcement bag is the most common mistake. Without a specific primer and a finishing sealer, the coating will stain, absorb water, and peel off. The sealer is what makes the surface waterproof and washable.
Layer Function Coats
Primer Adhesion to the existing substrate 1–2
Base or preparation Body and leveling, with mesh if needed 2
Finish or fine Texture and final color 2
Sealer Waterproofs and protects against stains 2–3
What substrates can it be applied on
  • Tiles and stoneware: Yes, provided the pieces are well adhered. Tap them: if they sound hollow, they need to be repaired first.
  • Concrete and terrazzo: Ideal substrate.
  • Plaster and plasterboard: Yes, on walls, with a specific primer for absorbent substrates.
  • Underfloor heating: Compatible, but the pre-heating cycle must be followed as indicated by the manufacturer.
  • With rising damp, no. The source must be resolved first; otherwise, the microcement will lift.
Application, drying times, and maintenance
  • 1 → Allow 4 or 5 days of work due to the layering and drying times. It's not a one-afternoon renovation.
  • 2 → It is applied with a trowel in thin layers, sanding between coats. The result largely depends on skill: if you are not experienced, try it first in an hidden area.
  • 3 → The substrate's expansion joints must be respected: if you cover them, the crack will reappear on top.
  • 4 → Wait for the sealer to fully cure before walking on or wetting the surface. This usually takes around 7 days.
  • 5 → Clean with neutral soap. No ammonia, bleach, or abrasive products: they damage the sealer.
