Microcement is a decorative coating made from cement, mineral fillers, and polymer emulsion.
It’s known for a smooth, seamless, and durable finish that can be applied on walls, floors, and even ceilings.
Originating from Spain and Italy, it became the “minimalist luxury” material in interior design.
1.What is Microcement?
Microcement is a decorative thin-layer coating composed of polymer emulsions and cement-based mortar. It features excellent adhesion, flexibility, and wear resistance, making it suitable for seamless wall-to-floor finishes. Microcement was developed to overcome the shortcomings of traditional cement plasters such as cracking, efflorescence, and poor adhesion.
2.What Are the Layers in a Microcement Coating System?
- Primer: Improves adhesion between the substrate and the coating.
- Microcement Layer: The main decorative layer made of polymer emulsion and special cement-based powder.
- Intermediate Sealer: Prevents efflorescence and seals micro-pores.
- Top Sealer: Offers waterproofing, stain resistance, and abrasion resistance.
- In some projects, a fiberglass mesh is added to enhance crack resistance.

4.Why Is “Cement Plaster + Hardener” Not True Microcement?
Some manufacturers promote “cement plaster + hardener” systems as microcement, but these lack flexibility and crack resistance. Traditional hardened floors are very hard but prone to cracking. When applied in thin layers (2–5 mm), cracks and delamination occur even faster. True microcement focuses on achieving a balance of thin-layer strength, flexibility, and adhesion.
5.Why Is Microcement So Profitable for Paint Manufacturers?
- Microcement is a high-value decorative material.
- Compared with traditional latex paint, it has lower material cost but higher selling price.
- Globally, it is used in luxury homes, commercial interiors, and minimalist designs.
- The per-square-meter profit margin is typically 3–5 times higher than conventional paints.
