Commercial Power Washing using NMD80 on 100,000 Sq. Ft. Building!

[@colonialfiend]

When you said nmd80 eats pump sprayers, I lol'd. That's an understatement. That stuff is magic but it's highly acidic. Also, the soapstone you were cleaning is highly susceptible to efflo especially when using pressure. It's so damn porous and holds the water and forces out the calcium

Nmd is wicked hahah, it works amazing though! I agree, we do have a chem to get the efflorescence out which is great, we used it on a limestone house last year and it came out amazing
