“I did a side-by-side comparison of the Masonry Flat product and one of your competitors and found that it had much better coverage. It adhered to the surface better and wouldn’t scratch or chip off. We are really pleased with it and with only 2 coats needed, it has better value and performance.”
– Randy Parks

20 Year Warranty

Romabio Masonry Paints are Italian designed mineral paint technologies that have been proven over time. They have a similar molecular structure to that of the brick and masonry surface, and are highly permeable (perm rating of 70+). This contributes to a breathable wall system which means water moisture contained in the parts of a structure or surface can diffuse outward without resistance, keeping walls dry and preventing structural damage over time.

They have extremely high-UV resistance and are naturally mold-resistant. We guarantee they will last 20 years with no peeling or chipping when applied properly as a 2 coat system.

Environmentally Friendly

Romabio Masonry Paints are BIO (bio-logical), made from nature. They are not acrylic or latex paints. They are mineral based products different than any other paints in the industry and are derived from sustainabile materials to create a natural, breathable coating.

They go beyond just Zero VOC and are toxin-free, odorless, do not contribute to asthma, and hypoallergenic. You can trust our paint is safe for you, your family, and the environment.
