Zinc Sulfate Monohydrate - 35.5% Zn - 99% Pure - 1 Pound

Mixes with water well and sprays well from a hose adaptor. It killed the roof moss after one week . Much cheaper than buying a 1 quart bottle for $20 that can cover only 10 x10 meters. This bag will allow for high volume moss killing . I had used the other so-called moss killers using Fatty Acid. A waste of money and time as the moss did not die.

Works good for getting rid of gofers

price great a at product Great

Same as above

I have my shed under oak trees, after spring the leaves and dust are dusty and create a lot of mildew, green stuff. After a year and a half is clean and the shingles are not broken. It saves a lot of money on the new roof. I sprinkle it and let it rest for a couple of days until a rainy day.

Must have for garden

over priced for a cheap to produce product

I have been electro plating bolts and other steel items. Most are rusting from off of a vehicle. I use wire brush wheel to physically remove the rust. I also use muriatic acid or electrolysis with water with wash-soda. Connect the rust part to negative terminal and positive to steel like re-bar. This works well removing rust but takes a long time. I usually do a day or 2. The electroplating with zinc, is much quicker, like 10 minutes. Clean with wire brush, and repeat a few time. I usually go until I like the look of the plating, and then do it one more time. I have done zinc plating on parts I have welded, which works pretty well.

This zinc sulfate monohydrate product exceeded my expectations! With a purity of 35.5% zinc, it's exactly what I needed for my agricultural applications. The packaging was sturdy, and the product arrived promptly. The purity of 35.5% Zn ensured potent efficacy in my applications. The quantity provided great value for money. Highly recommended for anyone looking for a reliable source of zinc!

For roof moss, this is the stuff. Killed all my roof moss. Mix with warm water and use a garden sprayer with a straight stream to improve reach. I did my whole roof from a ladder, didn't even have to step onto the roof. Be careful not to get it on your grass or other plants, that would be no bueno.

Much smaller amount then I anticipated. However.. it does seems to eliminate the moss problem, but doesn't cover much of an area. I just may not have paid enough attention to the description, and expected a little more product

Sprayed it on my asphalt ahingle roof which typically gets moss every year. Waited until the dry months to spray the roof with it after brushing off existing moss (as I usually do, and it always grows back) and making sure to soak moss areas, at least 6mo ago, mid winter now, no moss. So, I guess it works. Didn't use much, mixed with water in pump sprayer. Can't remember exactly how much, but maybe a couple tbsp per gallon is all. Quite surprised it worked so well. summer 2024 update: roof free of moss; usually grows back every winter. Nothing this year. Going to spray some more on to keep it away. Really, a couple tbsp per gallon is all that was needed. fall 2024 update: south east facing area of roof getting some moss now as the rain is back, just sprayed it again without physically removing the moss, we'll see if it dies off without physical removal this time.

I used this to clean up the moss and dirt off my concrete steps and it worked perfectly. Will definitely buy again
