Romabio’s Potassium Silicate Paints are mineral-based paints and primers. We at Austin Natural Painting believe this is the best substitute for traditional interior/exterior acrylic latex paints or acrylic waterborne house paints. Romabio products provide superior purity and performance. Austin Natural Painting uses the Domus Collection by Romabio, which is hypoallergenic and free of the toxic solvents and chemicals that are present in acrylics, yet these paints still great adhesion and greater wear and durability. And a high mineral content contributes to its form and function: unique light refraction creates extraordinary luminosity and high pH levels prevent mold.
