– Jen Fancher, homeowner

Complementary Products

Romabio Algae and Moss Cleaner is the best solution to eradicate your algae and moss growth without using bleach or other toxic cleaners. It can be applied in conjunction with any type of paint application.

For best results and to prevent further growth, apply Romabio Mineral Shield to lock and protect your painted surface on porous masonry surfaces. Algae, moss, and mold tend to grow heavily in areas that water penetrates consistently without the ability to dry and evaporate. Using the Romabio Mineral Shield as a top, invisible coat on your painted, porous surface will repel the water and prevent growth.

Romabio Mineral Shield only works on porous, exterior surfaces. For all other surfaces, apply the Romabio Algae and Moss Cleaner as needed.
