Question: Can this product be easily applied by a no-professional?
Document: recommended by professional floor tile person. I applied this 3 times. I have a beauty salon and was constantly scrubbing the black out of the grout lines....It is working great. The hairspray does not build up and the grout has remained light in color.....The professional said to apply it until water poured onto the grout  would stand on top and not seep in. That was 3 coats....Excellent product...it works
I purchased this product to seal some flagstone around my pool. Applies easily and works as advertised. Price was good and delivery was prompt.
Lowe's has the same brand, but different model number. The Lowe's version has horrible reviews (milkly residue) and this one works as advertised. We applied as directed and didn't have any issues. Seems to be working fine.
Applied to the stone a few years ago according to the directions on the bottle. Stone looked great until an unfortunate gun polishing accident in the bathroom. I was sad to discover it did not actually make the stone bullet proof.
As the site pointed out, Stonetech is actually a tile sealer for porous type tiles, but works great as a grout sealer. The test was cool. I did a small area, let it dry for a couple of hours, did a second coat and waited a couple more hours. I then took some water and poured it on the unsealed grout and watched it soak in immediately. On the treated grout, the water beaded beautifully like I had applied it to a piece of plastic!
This is a great product. I contacted DuPont directly and they promptly replied. They advised me that this product is great for granite and grout. Love a multi tasker!
Not a single remnant of the night's activities remained. I will probably throw down another coat after the patio sits for the winter. We have a busy summer of entertainment planned. StoneTech is a product worth every penny of the cost.
Super protective too. Put on a new flagstone area near grill to product from grease spills. Unprotected, one spot was agony to clean up. Did the entire area with a roller which went on fast and easy, dried invisible.
Expensive; however, this seller's price was the very best for this excellent product. After cleaning the patio, application with a garden sprayer was very easy and product did everything it was advertised to do. Last time we hired a landscaper to do this and it cost 3 times more and looked only half as good after he was finished. Highly recommended.
It takes a good amount of effort to keep it on. The floors are much easier. Just fill up the grout lines and let it sit. Then go back over it and wipe the tiles down. I did not see any problem with streaking or staining.At this point the rating means almost nothing other than that the product was easy to use. It's pretty expensive so if it doesn't hold up well for at least a couple of years it will be very disappointing.
Answer: yes
