Fantastic
When we start Renovating our 1920s home we had uncovered a Hidden treasure. I always wanted a fireplace just for decoration and this was a perfect opportunity. But After cleaning off all the plaster I want it's something to seal the fireplace without altering the Original look. I came across this stuff, the price seemed reasonable and seemed to be what I was looking for. I am telling you, this stuff is FANTASTIC, No odor, easy to use, Easy clean up and does the JOB! It puts me in the mind of a water down glue or maybe like mod podge. Dries quickly, with a A very mild satin finish. You can wipe it, and The very best part no more mortar falling out!!!! I even Put it in a spray bottle to apply inside the fireplace. It says you can apply 2 coats but one did the trick. I give this stuff 5 stars and will use it to apply to the rest of the chimney. I posted pictures the first one is from before using this product, you can see it doesn't change the look.

The perfect sealant for interior brick
We bought this sealer for the first brick wall we exposed in our 1905 home and it worked like magic. Since then, we have used it on two additional walls as well. Anyone that has exposed an old brick wall knows that the amount of dust is insane and even touching the brick releases a cloud of dust. We were desperate for a solution that would limit the need to vaccuum and sweep dust and debris from the wall. From the second we applied this sealer, the dust was trapped in. It’s been on for over a year now and we are still completely dust free. We applied 2 coats with a roller and brush and found application to be super easy. It has a slight shine which gives the brick a finished look without ruining its character. Before stumbling upon this sealer I researched home improvement store products and they were double the price and half the quantity. I can’t speak from experience but I’m sure they would not do a better job. I had to leave a review because this product is really amazing!

Interior brick walls
I was looking for a matte finish for indoor brick walls that are >100 years old. The purpose was to reduce the amount of brick dust. This product was the consistency of water and worked well in a pump action hand held sprayer. I used a masonry brush to ensure complete coverage. It went on milky in places but dried clear and even though the sheen says “satin” it looks matte to me. The bricks may have darkened slightly, but IMO the color is deeper and richer. I could not be more pleased. Used two coats 2 hours apart. This was an easy project, except for taping up the plastic to protect ceilings and walls, which took longer than the spraying. And no brick dust!!!! Highly recommend

Great Product
I love this product. Our walkway ( Picture #1) was put in 19 years ago, and we were having some grout erosion, plus I wanted to have some sheen on the brick surface. I used a paint brush and applied 3 thin coats of the brick sealer to our bricks. I love the sheen it has (Picture #2). It was so easy to apply. However, I read the other reviews on it and was careful to let each coat dry thoroughly before applying another coat. I bought the Satin coating. The picture doesn't do it justice. The brick really look clean and fresh. I would buy this product again.

Fixed Crumbing Brick / Brick Dust
I have a large exposed brick wall, the home is over 130 yrs old, and the brick is original. I had 8 total bricks that must have been missed with the sealing process when the home was rehabbed. They were constantly shedding dust and at times pretty large flakes, even small rocks if they got bumped. I got this, used a handheld spray bottle that I cleaned out, tested a few i found around the house, looking for the one that produced the finest mist. I prepped by using by handheld dyson with a soft brush, vacuumed very gently the day before, then the day of I used the crevice tool and just placed it on each brick, bit by bit, and held it to get all the loose material. Sprayed the brick after a good mix of the sealant, I sprayed (this stuff is basically water consistency) pretty heavily, waited 2 hrs then did it again. I had intended on then brushing the sealant on, but there was no need. Now that it is fully dried I have touched and brushed the brick with nothing coming off. Its like a glue almost. It did leave a slight sheen, but the bricks are just above the base board and its not noticeable. Over a few months it will probably mellow out. Very happy, and surprised that it worked so well on 2 of the bricks that were really shedding material. FYI I have a handheld pump sprayer but its coverage was going to be way to aggressive for the job at hand, if you need to do a whole wall, I think a pump sprayer would be the ideal tool.

I can't believe how badly this product performed!
I bought two jugs of this at $30 each, to seal up an old brick wall that I recently exposed, after years of it being covered by plaster and paneling. I brushed the brick, cleaned it and rinsed it according to instructions. I let it dry for several days. And then I applied the sealer with a brush for the first coat. Went back and applied a second coat with a sprayer a few days later. Within a week, a majority of the bricks became cloudy. After two weeks, the cloudy bricks began to shed off the sealer. After a month, the shedding was so bad that I decided to clean the wall up again and seal it with another product. You can see by the attached video, how horribly the product adhered and how easy it was to just wipe it off with a rag. I was very disappointed in this product, and cannot recommend anyone else attempt to seal anything with it. Perhaps the brick in my wall was just not compatible? Perhaps I got a bad batch? Hard to say. But at $30 per jug, it's not worth trying again.

Fantastic Product! Seals Brick and Mortar Perfectly!
Best sealant for interior exposed brick. After trying so many sealants from local stores and being so disappointed in the results, I decided to order this product and give it a try! I was very impressed. We had exposed old brick fireplaces (over 100 years old) in our home and wanted to keep them exposed without having to re-point all the old mortar. In order to be able to do so, though, we knew we had to find a product that would not only seal the old bricks, but also the mortar to prevent it from crumbling. This interior/exterior brick sealer did the trick! It does leave a slight sheen once dry, but I am more than happy to have that if it means I don’t need to worry about the bricks decaying and can wipe them down in the future if needed. The product is very watery so I would recommend brushing it on (starting at the bottom and working up) and then making sure to quickly back brush any additional drips right away so as not to leave any excess product on the bricks below.
