Maintaining A Slate Staircase

These photographs were taken some time ago however I thought they might be interesting as Glasgow has an interesting mix of architecture and occasionally we are asked to clean some unusual buildings including this one which had a stone winding staircase faced with slate tile which was overdue for a clean and seal.

Cleaning a Slate Tiled Staircase

Stairs are a high traffic area and if there was any sealer left on the slate treads it was minimal so I decided to apply a strong dilution of Tile Doctor Pro-Clean. This was left on to soak into the slate tiles for about 20 minutes before being scrubbed in by hand (no room for a rotary machine).

This was worked into the slate and grout until I was happy the tile and grout was clean. The soiled cleaning solution was removed using a wet vacuum and the floor neutralised with more water to ensure no chemicals remained on the floor prior to sealing.

Sealing a Slate Tiled Staircase

It was a small area so it only took a few hours for the tiles to dry so later that afternoon I was able to seal the slate for which we used five coats of Tile Doctor Seal and Go which adds a nice subtle sheen finish and will protect the tiles from staining going forward.
