I used this to seal marble tile and grout. I had used another product in my other shower which worked fine with my kitchen granite counter tops, but marble and grout are more porous. After applying this product two time with paintbrush and then wiping down five minutes afterwards with moist towel, my shower was sealed real nice. I even went back and re-did my other shower. I found it best to pour a little bit in cup and apply in uniform direction with brush and wiping down in same direction. This stuff is top notch, but open a window or turn on an exhaust fan as it has a potent smell.

Q: What is the difference between 511 Porous Plus Penetrating Sealer and 511 Impregnator Penetrating Sealer? I need it for concrete kitchen countertops.

I used two coats of the 511 Impregnator Sealer on the white grout between my porcelain floor tiles in my kitchen. Despite frequent cleaning, it wasn't long before the grout became discolored, until now where it is black. Would the 511 Porous Plus be more effective in keeping the dirt out of the grout? If I should apply the Porous Plus, how do I prepare the grout after I clean it?

Q: How many sq feet does a pint cover?

It depends on what you are sealing. For slate, flagstone and Saltillo about 250-300 sq. ft. per quart. For polished stone--granite, marble --likely 1000 sq. ft. per quart. For slate I use about 1 Qt. per 300 sq. ft. A bit more with Travertine. It does a great job. I recommend their cleaner prior to sealing. A Pint of the cleaner goes a long way. Hope this helps.

Q: Can this be used effectively on a slate floor?

According to the instruction label on the back of the product, yes, it can be used on a slate floor.
