Can I apply Another Sealer over Slate that has been sealed?
QUESTION
I just had my main bathroom done in slate tile (black rust slate) with a gray grout, and the floors in a pebble stone tile. I chose the 511 Impregnator sealer to seal the slate walls and the pebble floor. After 24 hours of drying I asked my contractor to put a second layer of the Black Diamond Wet look sealer for the slate tiles to give it a wet sheen. The contractor said that as he was applying her Wet Look sealer, it wasn't having the desired effect. He said that the tile can't take anymore sealer and the wet loo sealer won't work on an already sealed tile. My question is, is there a way that I can get the "wet look" sheen on my slate tile that has already been sealed with the 511 impregnator? Is there a product out there that I can use or re-seal with a better product? Please let me know. Thank you.ANSWER
ANSWER - Not all sealers are compatible with each other. There are sealers that are surface type sealers that will give the stone a wet look, but they are non-breathable sealers and not good for stone. There are breathable sealers that can give a wet look that are designed for natural stone.Miracle Sealants who makes 511 Impregnator also makes a sealer called 511 Seal and Enhance that is suppose to give stones a wet look. I would expect that they are compatible with each other, but there is a chance that the 511 Seal and Enhance might not work as effectively if it can't penetrate into the tile. You need to check with the manufacturer to see if they can be used together.
Now that you have used sealers from two different manufactures on top of each other, the Black Diamond sealer over the 511 Impregnator there could be compatibility problems. You might have to strip the existing sealers off of the slate and then reseal it. Best bet is to check with Miracle Sealants.

I have a small concrete bathroom countertop that I have applied 511 seal and enhance on.
Is there anything I can apply over the top to give it a glossy look?
What you ought to do is polish the concrete countertop. I would assume it is a dense concrete and it should be able to be polished. That way you have no sealers or coatings to trip off. Although you may still want to use a penetrating sealer over it.
You just need to use diamond pads on buffer and burnish the surface. I would look for a local professional who specializes in polishing concrete. A lot of floor covering installers do this kind of work.
Hi, I honed my marble end table to get out the etch, then I used a marble polish to bring the shine back. Can I use the 511 enhancer/sealant over the polish?The coffee table is a super high gloss and the color is richer. If I could get the color darker on the end table, I’d be happy with my HARD work.
Marble is very dense and technically impervious. You can seal it with the 511 Impregnator, but you have to wipe off any excess immediately after applying with a lint free cloth to prevent the surface from becoming tacky.
You can try using the 511 Enhancer that for porous stones it gives a wet look, but since you have a marble it might not make a difference. Test it out first to make sure you will be satisfied with the results.
I used Black Diamond Wet Look Stone sealer on my slate fireplace steps about 3 years ago. The slate was had never been sealed prior to that. The product did a beautiful job. Is it possible to reapply this wet look sealer? Thank you.
Depends on the type of sealer. Some sealers you can just reapply, but there are certain solvent sealers where you have to strip it off before resealing.
