How to Use Diversey Premium Slate Seal:


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

  1. In order to determine the compatibility of Diversey Premium Slate Seal with your slate floor a test area of one or two tiles should be attempted before sealing the entire floor. If the finish in this area meets your requirements continue to seal the remaining tiles.
  2. Surfaces to be sealed must be thoroughly clean and dry and free from grease, oil, paint, acid, efflorescence, and traces of grout.
  3. Newly laid areas need 4 - 6 days to allow mortar and grout to cure and dry prior to sealing. Slate that has been acid washed needs at least 4 weeks for slate to dry prior to sealing otherwise floor can turn white.
  4. Surfaces previously sealed with slate sealers other than Diversey Slate Seal, Diversey Premium Slate Seal, or polished surfaces, must have all traces of old sealer and polish completely removed with suitable strippers.
  5. Prior to sealing the slate, the slate should be cleaned with Diversey 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 Premium Slate Seal with a paint or lambswool applicator. 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 Tasman Slate Seal 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 Premium Slate Seal 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 Premium Slate Seal.
