Haze on polished concrete usually comes from one of five causes: skipped grit steps, polishing with dirty pads, densifier applied too late or unevenly, moisture trapped under the finish, or a final step that wasn't burnished dry. Fix it by going back one or two grits and re-polishing clean, then finishing with a dry burnish.
| Cause | Signature | Fix |
|---|---|---|
| Skipped a grit | Haze everywhere, scratches visible | Re-polish from the skipped grit up |
| Dirty / loaded pads | Streaky, patchy haze | Clean or dress pads, re-polish |
| Densifier not absorbed | White film or patches | Re-scrub, re-apply evenly, let cure |
| Moisture under finish | Cloudy after sealing | Let floor dry fully, re-apply |
| No final dry burnish | Dull gloss, milky sheen | Dry burnish with a burnishing pad |
Burnishing pads are the key final step; resin pads re-run the polish.
If the haze is uniform, a dry burnish may fix it. If it's from skipped grits, the affected areas need re-polishing from the skipped step.
Usually moisture or incompatible products. Let the floor dry completely, and test the sealer on a small area first.
Yes — worn or loaded pads stop cutting evenly and leave a streaky haze. Replace or dress them.
Haze is a process problem with five known causes — diagnose it by pattern, go back a grit or two, clean everything, and finish with a dry burnish. Fix it once and the floor shines. JOY TECH's pads and burnishing range cover the repair.
