First, I cannot find on your website where you are located other than Colorado. Where? Is this a business that has a storefront? It would be nice to know if this is a place I can visit for more help and information....
I recently purchased a home that has a lot of flagstone inside and out. There is a back flagstone patio, and it is in the home in a living area and the master bathroom. It looks like areas in the home were sealed, but that is coming off. Do you have to strip all sealer off before redoing?
In bathroom, it looks like dark mold or mildew may be growing between sealer and stone. Is this possible?
Is it safe to use salt to kill slugs outside on stone and inhibit ice buildup in winter? Or will salt discolor the stone?
