Hello! I'd like to limewash or whitewash the exterior brick on my home. I want to achieve the look on the attached image. I have done some research and would like to use a lime based product to change the color, without sealing the pours on the brick. Sealing the pours could possibly create moisture issues for my home. I live in the south and moisture can be an issue. I found this product: http://romabio.com/. But are there any others out there? Can you purchase lime powder and make your own?

Thanks in advance!
