No, but 2 of the products I have looked at caution about either darkening or lightening the tile. I think the customer is willing to take the risk. As it is now, it's a lawsuit waiting to happen. Slippery porcelain tiles right outside the lobby doors. Covered but rain blows in making it very slippery. Adjacent doors are glass and stainless steel. I gather this product has the ability to etch them too. Lots of masking to do.
They do but not the look they're going for. More the look of surprise when someone sues them.
Yonks ago, 3M Safetywalk had it in clear, as well as the usual gray,black, white etc. Good product.
Not yet, I am meeting this week to try to agree on a price. More complicated than I thought. After cleaning, have to mop product on, then neutralize with a baking soda application. Water will neutralize as well but takes longer.
