Thread: Sealer question

One of the office buildings that we clean wants their stone floors cleaned and sealed, they have been sealed before grout and the tile(not by us) and the lady likes the wet look on the floor.
since it has been sealed the tiles and grout look really clean no sealer flaking anywere just not as shiny as it used to be, so should we just scrub it with a floor machine and seal again or strip it and seal again,

Can I use a spinner or would it damage the seal?

I also would like to know if a floor has the grouts sealed but the tiles are dirty and somebody uses a spinner does the pressure damages the seal and new sealer has to be applied to the grout?

Pressure will likely remove some of the seal. But pressure is not the biggest enemy here. Rather it is the alkalinity of your cleaning agent that breaks down the seal.

Cleaning with high pressure and an alkaline cleaner may not remove all of the seal, but it will remove some of the seal. So it is a good idea to seal after restorative cleaning.

For a sealer with a "wet look" for stone, consider a color enhancer. These are impregnating seals that darken the colors and increase the contrast to make the stone look wet and make the colors really stand out.

You should know what type of stone you are working with before you begin cleaning and before you apply high pressure. Some stones can stand pressure better than others. Many stone syrfaces are sensitive to acids and/or chelating agents that may be in some tile cleaning products.

I suggest you get a little training before trying to clean stone. My Stone reference guide would be a good starting point. I would be glad to email you a copy. I just need your email address.
