Rated 3.3 out of 5 by 29 reviewers.
Rated 1.0 out of 5.0 by Tilelab grout sealer is useless I could have used water and gotten the same results. The 30 year old house we bought has cream colored porcelain tile and grout in the kitchen. I worked for weeks getting the grout cleaned and I was so ready to get it sealed and be done with it. I started with my 10 x 10 dining nook. I applied seven, yes 7 coats and still no go...hey the grout was finally clean and I didn't want to scrub it again. I finally gave up and bought Dupont Heavy Duty Grout Sealer which only took two coats to seal and was half the price of Tilelab. October 4, 2015
Rated 5.0 out of 5.0 by penetrating sealer We have used this product on the tile in our homes front entrance. It has held up very well. Then we tried it out on the newest adventure. A hearth for our woodstove. Turned out great. Easy to use and makes clean up easier on the hearth. November 5, 2014
Rated 1.0 out of 5.0 by Warning: think twice before using this product I purchased this product to seal the grout in my shower and on my tile floor in my newly renovated bathroom. It was recommended by the staff at Home Depot after showing the salesperson exactly which tiles and grout we used in the project since all were purchased at Home Depot. We were given simple instructions by the HD salesperson, which matched the directions printed on the bottle. I used the sealer in two small test areas; one on the grout surrounding my ceramic tiles and one one the grout surrounding my mosaic tile insert. There was no problem with the test areas or other larger portions of the shower as I proceeded with the project. However, as I continuned to seal the grout surrounding my mosaic tiles, I did begin to have a problem. About 1/2 way through the job, certain tiles within the mosaic discolored to a yellow/green tint. I immediately stopped using the product and tried to rinse and wipe it off the mosaic tiles, but the damage was done. I have since been corresponding with Custom Building Products (who makes the SurfaceGard) for the past 2 months. They have indicated that the sealer is safe for honed marble (which is what my mosaic tiles are made of acoording to HD's website). They tried to infer there was a problem with the grout or the thinset, until I informed them that both of those products were also manufactured by Custom Building Products. (I used Polyblend grout in Alabaster and Porcelain Tile Fortified Thin-set Mortar in white.) They tried to tell me the discoloration was grout staining and said I should have sealed the mosaic tiles with their product before I even hung them in my shower, and then proved this point to me by sending me a quote from the National Tile Contractors Association manual. I was taken aback by this considering it's a DIY project and I folllowed their label's instructions. They also told me I should have gone to their website and read the full technical datasheet for the product before using it. I have since had the Grout Doctor out to my home to see if they could assist me in removing the discoloration and they indicated the damage is not grout staining because grout staining would not turn green and would not etch the surface of the tiles as has happened. I informed Custom Building Products of Grout Doctor's diagnosis, but they have made no comment on it. Overall, Custom Building Products has repeatedly offered varied explanations for the discoloration of my mosaic tiles, all squarely placing the blame on me. They requested a sample of my SurfaceGard Sealer, stating they would test it and if it is found to be defective they will stand behind their product. I sent it to them via Fed Ex 2 day shipping on 8/27/14. As of yesterday (10/6/14), they indicated that their lab is backed up and they will get me the results as soon as they are available. Please use caution if you decide to use this product as it may not work well on all surfaces the label indicates it should work on, and the company does not to seem to be very willing to help if there is a problem.

Rated 2.0 out of 5.0 by Good Sealer BUT Used this product to seal grout on kitchen floor tiles. Followed direction to avoid sealer turning white if puddles of product are left to dry. I installed one coat then a second, what didn't soak in I soaked up with a rag. I used a smoke colored grout, its almost white color now, lighter than before I used the sealer. I think it will repel lquids but don't care for it turning my grout white. June 16, 2014
Rated 1.0 out of 5.0 by Caused more problems than it solved Used the spay on method and wiped down with dry towel.....probably should have been cleaning with a sponge and tons of water. Result tiles formed a haze that a full day of using a floor polisher did not remove, was using tilelab's stripper with the polisher. Also, many areas of grout dried to a hazy white color. Professional tile cleaners and color grout coming in next week to try and repair the damage using this product caused. May 22, 2015
Rated 2.0 out of 5.0 by Not good for colored grout I would not recommend this product for colored grout. I followed directions as stated. Tested in an inconspicuous spot under vanity. Our tile is porcelain brown with brown grout to mimic wood flooring. When tested under vanity. the grout when dried ,was a significantly lighter color, drawing attention to the grout and not the floor. This product may be great for non colored grout, but not colored grout. January 27, 2015
Rated 1.0 out of 5.0 by Poor sealer for new grout I recently installed ceramic tile in two new showers. I had a small bottle of silicone sealer but I did not have enough to complete both showers. I applied the remaining silicone to the floor of the first shower. I waited 24 hours and when I applied the second coat, the grout was so well sealed that the second coat would not penetrate. I went to home depot and picked out this product which was recommended by the sales person. I applied the tilelab product to the second shower pan and waited 24 hours for the product to dry. Then I applied a second coat and I was shocked to see that most of the grout I had sealed, was easily penetrated by a second coat of sealer. I then waited another 24 hours and applied a 3rd coat which easily penetrated the second coat of sealer. At this point most of the grout should have been sealed and the 3rd coat should not have penetrated the grout. This sealer did not seal the grout and I would not use it again. December 7, 2014
Rated 4.0 out of 5.0 by Contractor Recommended I needed to seal some mosaic tile I installed as a backsplash behind my cooktop. A tile and flooring contractor I know recommended the TileLab sealer. Sealer is very easy to use. Seems to be very effective. My only 'complaint' is the size of the bottle. It would have been helpful if a smaller spray bottle was available. I needed only a little bit.
