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. Review: 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! ## Features - INTERIOR AND EXTERIOR PROTECTION: Shields both interior and exterior brick walls with a water-resistant barrier.

Application is relatively easy, I used a brush and a hand sprayer. Starts milky white with bluish tint and dries out clear. Seals dust in between brick well. I did not have any issues with milky white residue like other people wrote. Once it's dry - it is clear. I was hoping for little sheen, kind of a wet look, like advertised - that did not happen. Color stayed exactly the same. I applied 2 coats in some places and once it dried out - no difference. Otherwise it is a fine product. I would still use it again ## Frequently Bought Together - MasonryDefender Interior/Exterior Brick Sealer, Satin Sheen - Clear Water Based Acrylic Sealer - Reduces Brick Dust & Makes Interior & Exterior Brick Walls Easy to Clean - 1 Gallon - DQB Industries 11937 Masonry Brush, 4-3/4in - DQB Industries 11943 Dqb Masonry Brush, 6-1/2 in L, Tampico Colored Poly/Synthetic Bristle Trim, 6-1/2In --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/64705011-interior-exterior-brick-sealer](https://www.desertcart.co.uk/products/64705011-interior-exterior-brick-sealer) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-28*
