Resealing Microcement Surfaces

Once a microcement surface is sufficiently sealed, it will remain strong and stain resistant for years to come.  If you are noticing signs of wear & tear, then it most likely needs an additional coat of sealer.

This guide tells you everything you need to know about resealing microcement surfaces.

When Do I Need to Reseal Microcement?

  1. Insufficient Sealer Applied

If you notice the surface is darkening when wet or appearing to stain easily in the first few weeks after installation.  It is most likely that insufficient sealer was applied to the surface during the installation.

For the microcement to work effectively, it’s important that the correct amount of sealer is applied to the surface.  If there is sealer left after application, it may be necessary to an additional coat, to ensure the correct consumption is applied to the surface.

Sometimes, sealer can get caught up in the roller or tray, preventing enough sealer from getting onto the surface, even when all of the sealer has been used.

If your surface appears to be staining easily or darkening when wet, it’s essential that another coat of sealer is applied to the surface.

  1. Following Repair Work

All fresh microcement that has been applied to the surface will to be sealed.

Likewise, if you have sanded back the surface for any reason, sealer will need to be reapplied to replace any that has been removed by the sander.
