Chemical Help
Permalink  
 


I am the Manager of a company based in Christchurch, New Zealand. We aim to treat roofs and paths etc for moss, mold and lichen without high pressure water blasting or using chemicals that damage the surfaces. The chemical we use is made in New Zealand and is very effective it just doesnt foam well or have easy coverage. It seams that your chemicals over there are good at foaming and easy to get good coverage. I was wondering if you would mind maybe sharing a trade secret as to what chemical you use so we can see if our New Zealand chemical company can make it for us or what additive you use that we could maybe add to our current chemical to get this affect. Even if you could just steer me in the right direction I would greatly appreciate it. If we could find an additive or alternative it would make our job much easier.

First if you would, tell us what your cleaning solution is made up of chemical ratios and compounds and we will offer you suggestions on foaming agents or surfactants that may be compatible.

Hi The best I can offer is the MSDS and TECH SHEET Hopefully that has the information you need. I know a little about chemicals and additives but would not claim to be a chemist of any level. This product also has a wetting agent that has been added to the receipe for us but we can get it without also. The wetting agent only speeds up the reaction of the sodium hype(bleach). If this dosn't work I think we might just try the apple sauce but would prefer to find an additive for our current chemical if possible. If you have any further suggestions please let me know. I'm eager to look at other options to make our work easier so it has less physical affect on the body in the long run.

Also one more little question....do you rinse off after using apple sauce or is it an apply and leave product?

THIS is your problem.
5 percent bleach roofs is way too weak , you need 12 percent Bleach.
Look at the formula here for Apple Cider or Apple Sauce, it calls for 12 percent bleach, or Sodium Hypochlorite, as it is properly called.

THIS is why your roof cleaning solution is not foaming.
Yu have made a comon mistake Mate, no worries!
