We are closing in on getting all of our floors finished up in the new building-all 8300 square feet of them! We’ve done cork, wood and LOTS of decorative concrete. Our latest concrete floor project for our laser cutting room was inspired by this rug picture:
I wanted to do something organic and VERY different, so I reworked our Royal Design Studio Bamboo stencil into a Bamboo Forest that we cut from the Modello masking material. I decided that the best way to achieve this look of mottled color variations was with acid staining and acid etching.
Acid staining involves spraying on diluted acid stains (essentially muriatic acid, mineral salts and water) and letting it work it’s magic as the acid etches and opens up the concrete surface to allow the mineral salts to react with the lime, creating the soft, mottled color. Once that was cleaned up and dry we applied the vinyl pattern and troweled gelled acid through the open areas of the pattern.
The gelled acid pulls the color back out from the concrete in the exposed and treated areas-again in a way that is random with subtle variations.
Acid is not the most pleasant material to work with and you must take precautions and get lots of ventilation going, but it’s a standard finish for decorative concrete and MAN it’s gorgeous!! Special thanks to Melissa and Richard for their help with this project. We actually were able to get through this in a few hours. This type of pattern would typically be used on a vertical wall surface, but the stripe effect on the floor really looks quite nice and makes the room seem a little bigger as well!
Speaking of concrete! Please check out this post from my Artofliving blog about our weekend wine country trip with the fabulous Bob Harris and Bob and Lee Ann’s harley ride across the country to raise money for Breast Cancer Research.
