You guys make up your own mind on the mixture and if it was a mistake.

Identical!

Yes Chris,..I noticed that as well.

Then how could the bleach powder be a mistake ? Perhaps they were thinking a finer grind will help water solubility issues ?

Abstract

The superfine grinding could produce a narrow and uniform particle size distribution in dry ginger. The physical–chemical properties of five types of ginger powders with particles size of 300, 149, 74, 37 and 8.34 μm were investigated. The size was smaller for ginger powders, greater for the surface area (from 0.331 to 1.320 m²/g) and bulk density (from 0.3069 to 0.3426 g/ml) and smaller for the angle of repose (from 51.50° to 46.33°) and slide (from 45.80° to 39.50°). The values of water absorption index (WAI), water solubility index (WSI) and protein content significantly increased with decreasing the size of ginger particles (p < 0.05). Interestingly, the values of WAI, WSI and protein content of ginger powder with a particle size of 8.34 μm during soaking reached 0.52 g/g, 33.70% and 84.93% for 60 min, respectively. SEM observations revealed the shape and surface morphology of five types of ginger powders.

Maybe Chris,..I think calcium is gonna be tough to dissolve no matter how fine it's ground,..especally in the concentrations needed to make a relatively potent roof mix,..I think that is alot of the problem,..so much is needed to make roof strength that the calcium just adds up in such a small amount of water.

Even if it all dissolves,..it's the properties of the CH that is the issue.

CH is just out of place for practical roof cleaning,..especially when there's SH readily available.

Even if their "special" blend of chemicals was off,..I would still think the MSDS would have been correct. So,..it is still just pool shock it would seem.

The problem is not so much the water solubility, it is what happens when the stuff dries/comes out of solution. You strained the shit, remember ? It still left a film.

Guest

Yes Chris,..that was my point,..it doesn't matter if it all dissolves or you strain it or whatever,..there is always gonna be the issue with calcium.

I did it alot many years ago,..and it was more work,..but it worked. I think they will be posting a method change before a product change.

Maybe they will sell it, complete with some Panty Hose to Strain it through ?
