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

Extremely Durable

Romabio Mineral Primers are Italian designed mineral paint technologies that have been proven over time. They contribute to a breathable wall system because of their mineral based qualities. They can be painted on acrylic or latex paint as a bridging gap between an acrylic system and Romabio mineral system and will provide extreme durability for the top, finish coat(s).

Environmentally Friendly

Romabio Mineral Primers are BIO (bio-logical), made from nature. Mineral paints are the healthy alternative to acrylic paints. They go beyond just Zero VOC and are toxin-free, odorless, do not contribute to asthma, SBS, and are hypoallergenic. All backed by 3rd party scientific testing, you can trust our paint is safe for you, your family, and the environment.
