Is Microcement Safe for Indoor Air Quality?
Once cured and sealed, microcement gives off very little. The products and sealers used decide its VOC level. What to check before you choose.
Once cured and sealed, microcement releases very little into the air. Most of any VOCs come from primers and sealers during and shortly after application, so the products chosen matter. Water-based sealers and good ventilation during the work keep levels low.
What microcement is made of
Microcement is cement, fine aggregates, pigments and polymers. The cement itself is mineral. The polymers and sealers are where VOCs can come from.
Sealers make the difference
Solvent-based polyurethane sealers give off more VOCs while curing. Water-based sealers give off much less. Ask for the technical and safety data sheets for each product.
During application
The room is ventilated while primers and sealers go on.
Sanding between coats is done with dust extraction.
Rooms are left to air for a few days after the final sealer, especially bedrooms and nurseries.
After curing
A cured, sealed surface is stable and inert in normal use. It has no grout, which removes a common place for mould in bathrooms.

Frequently asked questions
Is microcement toxic?
Once cured and sealed it is stable in normal use. VOCs mainly come from primers and sealers during application.
Are there low-VOC microcement sealers?
Yes. Water-based sealers give off much less than solvent-based ones.
