MasonryDefender Interior/Exterior Brick Sealer, 1 Gal - Clear, Satin, Acrylic for Vertical Walls - Reduces Dust & Makes Interior Walls Easy to Clean

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.

I've added 2 generous layers on my brick wall and it's still like before. I was expecting a varnish style finish that would help me control the "brick dust" effect and... nop. I saw a MINOR improvement, but not as advertised. I need to find a different product now... waste of time and money.

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!

The product was very chunky. Didn’t go on smooth. Looked like coconut shavings almost. I tried to shake the jug and constantly stir it but remained very chunky. I need to buy a new product because this didn’t go on the brick well and it doesn’t appear sealed

If you have to do 3 light coats then do that.I made the mistake in some spots of applying too much and it caused a white haze to form. But overall it looks really good. Think of it as waxing, you are trying to build the light layers up. You can also use somrthing like a weed sprayer bottle. Definitely helped using that, instead of using a spray bottle
