American Clay Earth Plaster has announced that recent test results for mold growth prove that the clay plaster does not allow for mold growth on the plaster surface.
The mold tests were conducted by an independent lab that utilizes ASTM standards, one of the most universally accepted testing parameters. Two tests were conducted: ASTM 3273-00 and ASTM G21-96. The first and most common test for wall surface materials had panels with American Clay’s original formulation (Loma) hang for four weeks in an atmosphere ideal for production of mold growth. The panels included every permutation of the Loma clay – alone, with add mix, with the company’s new Mud Glue, and even one without American Clay’s current mold-inhibiting additive, Borax. Control panels that will not prevent growth and are a known level were also included in the test. At the end of the cycle, all American Clay panels showed no signs of mold growth, a rating of 10 per the test standards.
The second test is one that shows fungus resistance. A fungus culture was placed directly onto the product (i.e. panel) to see if the product’s environment would allow for further growth. The tests on Loma, combined with their new Mud Glue, resulted in a “zero” test score, meaning no traces of any fungal growth were observed.
“When we received the official results, it was an affirmation of everything I expected. But then when we saw the results from our new Mud Glue product, I was ecstatic that we had something that could provide further benefit in the deep South, a place were mildew is just something you have to live with. We [American Clay] have provided a solution without all of the harsh additives usually relied on in the industry, providing an even healthier environment for people’s homes and workspaces.”
