Do you offer trim?

How do I clean slate?

Slate is chemically sensitive so only mild pH neutral cleaners should be used. Soapless cleaners are preferred because they minimize streaks and film. Mild, phosphate-free, biodegradable liquid dishwashing soaps or powders or stone soaps are acceptable if rinsing is thorough.

Showers and Baths: Soap scum can be minimized by using a squeegee after each use and using liquid as opposed to bar soaps. To remove soap scum, clé recommends the use of Miracle Porcelain & Ceramic Tile Cleaner.

 

What is shaling?

This is the process of the slate’s cleft surface to slough off during the first several months of floor (and sometimes, wall) use. This will not happen with every tile, just the tiles that have a section of loosened cleft surface. This process will only expose more slate stone underneath. This process is natural and is not a defect of the slate- but a natural response to wear and tear. It will finish once any loose portion of the slate’s cleft has come off.
