How to Use Diversey Slate Seal Gloss:


WARNING: Ensure good ventilation to disperse solvent vapours. Keep away from naked flames, sparks, etc.

  1. If sealing exterior surfaces, the area must be completely free of moisture to avoid the whitening or flaking of the sealer.
  2. The new slate laid on sand and cement needs 4-6 weeks to allow mortar and grout to cure and dry prior to sealing. New slate laid with adhesive can usually be sealed after 1-2 weeks. Slate that has been acid washed with Diversey LIFT OFF or other acid needs to be thoroughly rinsed with water to neutralise any residues of acid. The floor must be allowed to dry for 24 hours prior to sealing.
  3. The surface to be sealed must be thoroughly clean and dry - free of grease, oil, paint, acid, efflorescence, loose flakes of slate, and traces of grout.
  4. Surfaces previously sealed with slate sealers other than Diversey Slate Seal Gloss must have all traces of old sealer and polish completely removed with suitable strippers. Surfaces polished with Diversey SLATE FINISH must be stripped with Diversey RIPPER STRIPPER.
  5. Prior to sealing, the slate should be cleaned with Diversey’s TILE KLEEN. It should be continually washed until, after repeated washings, no slate dust appears in the wash-up water. Allow at least 24 hours for the cleaned area to dry. Prior to sealing give the floor a quick vacuum.
  6. Do not seal hot surfaces - all surfaces must be cool.
  7. Apply 3-4 even generous coats of Diversey Slate Seal Gloss with a paintbrush. Allow approximately 4 hours or until touch dries between coats.
  8. Avoid heavy traffic for 48 hours after sealing.
  9. To maintain the seal in dry areas apply Diversey SLATE FINISH as per instructions. Otherwise, simply apply Diversey Slate Seal Gloss to worn/dull areas as required.

COVERAGE: 1 litre will cover approximately 8-10m2 with two coats.

CLEAN-UP: Brushes must be cleaned with Diversey SLATE SEAL SOLVENT or softened by soaking in Diversey Slate Seal Gloss 10 minutes prior to reapplication.


Always read the label and follow directions for use. Kindly refer to the Safety Data Sheet (SDS) and Technical Data Sheet (TDS) before using Diversey Slate Seal Gloss.
