Not a Sealer but better
It is not a sealer it does protect from water but still allows breathability for the wall. Also very easy to apply. The delivery was straight forward. It is colorless and did not impact the look of the wall.
Completely invisible and waterproof
At this moment I am only testing the Romabio products before I use them on my house. Last night I tried the limewash and tonight I tried the colorless flat transparent water-based sealant. This product has zero odor which is very important to me. It brushed on easily. Second coat goes on before first coat is dry so if doing a large project you would definitely need to work in sections. I let this dry about 3 hours then inspected the bricks. The color was not altered at all and the sealant was ...
Thank you so much for sharing!!

Wonderful seal
After using the Romabio lime wash, we used the mineral shield to protect the finish. It was very simple and easy to apply with a garden sprayer. We were very pleased that it held up well after the first rain
Mineral Shield is a great choice to protect your Romabio finish from environmental moisture, and it's super DIY friendly!! Thank you for sharing ...

Make sure limewash is fully dried!
I recently repainted a limewash job I did 5 years ago. The brick started to turn a reddish color over the limewash so we repainted and put the shield on. Super easy to apply. Just make sure the limewash is fully dried before applying. I'm hoping it protects the brick from discoloration! Time will tell!
Mineral Shield is a great option to protect your finish from environmental moisture! Thank you for supporting Romabio :)

Easy to apply, coats well!
I thought it was super easy to apply and clean up was a breeze!
Mineral Shield is very user-friendly and dries quickly! Thank you for supporting Romabio!!

Easy to apply protection to our lime washed bricks
This product was easy to apply using a pump up sprayer. The day after applying it to our lime washed house we had several days of hard rain and our house still looks beautiful. So glad we used their Limewash and protector instead of paint.
Thank you! Mineral Shield is an important part of protecting your limewash finish, especially if you want to prevent the patina effect.

Spray, Pray, Done in a Day: The Sealant works!
I picked up the Romabio Colorless Flat Transparent Water-Based Mildew Resistant Sealant from Lowe’s, and let me just say—this stuff made me feel like a home improvement pro… or at least someone who watched two YouTube videos and believed in themselves. First off, it was shockingly easy to work with. No weird learning curve, no “what have I gotten myself into” moments—just open, apply, and pretend you’ve been doing this for years. Coverage was solid, too. It went on clean and did exactly what it...
Thanks so much for sharing your experience! Mineral Shield is super user-friendly and is a great option to protect your Romabio finish from moisture-...

Easy application
Application was easy and as explained. Obviously, I don’t know how it will work over time yet, but so far it has worked as promised as far as application and appearance hopeful this will keep the discoloration near the base of the house from building over time with rain, splash back stains.
Classico Limewash is super DIY-friendly!! It will age depending on its exposure to moisture, so areas more exposed to the elements are likely to get ...
