A sealer is not a one-time application that lasts the life of a decorative cement floor. Sealers wear down with foot traffic, cleaning, and UV exposure over time, and once they do, the floor underneath loses its protection. Here are five signs it's time to reseal.
1. Dulling or Loss of Sheen
A floor that used to have a glossy or satin sheen and now looks flat or patchy is one of the clearest signs the sealer has worn through, particularly in high-traffic paths like doorways and walkways.
2. Water No Longer Beads on the Surface
A properly sealed floor should resist water absorption — spilled liquid should sit on the surface rather than soak in. If water is being absorbed instead of beading, the sealer's protective barrier has broken down.
3. Staining That Wasn't a Problem Before
If the floor is suddenly staining more easily from everyday spills — oil, wine, coffee — that's usually a sign the sealer's protective layer is no longer doing its job, not that the underlying decorative finish has changed.
4. Visible Wear Patterns
High-traffic areas — entrances, walkways, kitchen work zones — often show wear before the rest of the floor does. Uneven sheen between these areas and the rest of the floor is a sign the sealer has worn unevenly and needs refreshing.
5. Colour Looking Faded or Chalky
UV exposure and general wear can cause a decorative cement floor's colour to look faded or slightly chalky over time. A fresh sealer coat often restores much of the original depth of colour without needing to redo the base decorative layer.
How Often Should You Reseal?
This depends heavily on foot traffic, cleaning routine, and UV exposure — there's no fixed interval that applies to every floor. Checking periodically for the signs above is a more reliable approach than assuming a fixed schedule.
