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.
Find the product that used and read their data sheet or call their technical service department to find your answer.
I built an outdoor kichen with a poured concrete countertop. After letting it cure for 30 days, I applied “Siloxa-Tek 8500 Ready to Use – 1 Gallon Penetrating Concrete Sealer, Water and Salt Repellent. Clear, Water-Based DOT Approved Silane/Siloxane for Concrete, Brick, Masonry & Pavers” over it to seal it.
It works as intended, but is not “shiny” (and my wife wants a shiny top). What could I put on top of this that would give it a shiny finish?
There are enhancer sealers but you will have to check with Siloxa to determine what would be compatible with the existing sealer. Sealers don’t last all that long in exterior applications depending on the climatic conditions to which it is subjected to.
Concrete slabs can be polished by burnishing it. You can hire a floor covering installer who specializes in polished concrete and see if they can polish your countertop.
Hello, need some expert help!
Had a contractor put in slate tile in entry and hallway (250 sf). He then applied Miracle Seal and Enhance; but it does not look great; nor is it shinny. I want only a slight shine. The tiles had great colors and now it got really dark but no shine.
Should I reapply a second coat? But I don’t want it to get darker.
Can I have it buffed out and then re-apply another sealer?
Can I apply another type of sealer onto it?
On another note, I’m also not happy with the grout he applied! Can I re grout? How?
Obviously, I’m not happy with the installer.

Slate is a very dense material typically with an absorption of not more than 0.45% so it is impervious by definition.
My experience with the Miracle Enhancer sealer is that it gives the slate sort of a wet look, which is a darker appearance. Depending on the type of slate it enhances the colors particularly if the slate has natural multiple coloring within it. It isn’t suppose to give it a sheen.
This is a penetrating sealer that supposedly is suppose to breath to some degree. There are surface sealers that can give you a sheen, but they don’t breath and they wear and require more effort in maintaining.
Normally this sealer can be applied over the first coat. It should be able to re-emulsify the first coat. So you can experiment and apply a second coat, but when you apply it, let it sit for a few minutes and then buff dry with a lint free cloth. Then decide if you like the results.
Remember this is an impervious stone so it doesn’t absorb much and is mostly sitting on top. It will wear depending on how much traffic and maintenance it is subjected to, but I believe the manufacturer says that you can reapply the sealer without having to strip the first coat.
Grout can be removed and reapplied but it is a lot of work and you are likely going to damage some tiles. You can apply a grout colorant to the existing grout to change the color of the grout, but it is a lot of work. You have to remove the existing sealer, you have to tape the along side of the grout joints, and it is a tedious process.
Can I apply 511 impregnator sealer over Microban grout renew? I have 15 year old tile floors that were not sealed and the grout is beyond cleanable. I’d like to apply the Grout Renew and then seal the entire floor.
First of all you have to review the data sheets of the products you intend to use. You have to verify that it is suitable for your intended use. You have to follow the directions and limitations they state.
There are a few products that use the term “renew.” One is an epoxy grout colorant that also seals the grout. So you would not apply another sealer over it. The 511 impregnator has to have a clean, porous and dry grout joint in order for it to penetrate into it and seal it. The sealer is only temporary and has to be applied periodically as it wears away.
