Works well- almost too well
Definitely a strong green dye. I sprayed it on my dead winter grass and it made my lawn look awesome. However, I had a neighbor get really ticked off when she allowed her white Maltese to walk through my yard to go potty and ended up with dyed deep green paws lol She was not happy and it wasn’t my fault that with the morning dew she allowed her dog on to my lawn while walking her, and it stained her white fur. She demanded that when I spray it I put a sign out so I will post a sign from now on, but maybe it will make her think twice before she lets her dog go potty in my lawn in the future lol

Great value for your money!!!
Good for the price and it stayed green for longer than expected. It was easy to apply and even though in the pic it might look too bright of a green, it wasn’t like that in person.

Works great looks great
It’s dye of course it’s messy It works like it should And I have no idea why anyone has complained about the color, I applied it on the higher side of the mixing instructions and got a deep green lawn! Looks great . Also looks like I have enough to cover the entire neighborhood a few times after using this in my fertilizer mix. Good product!

Bought this to see where I’ve applied my spray. It blends in well my grass. The color is perfect to keep that ideal look.

Not a good grass paint color
If your grass color is blue-green turquoise color , I don't recommended this color in fact I never see a color grass like this the color is out of for any grass color. This color it's too bright they need to make variety of color to match your grass and plus it's so messy I wear my gloves and it stain my hand and my clothes. I always careful when doing any painting work but not this product if a drop fall anywhere it's a big mess, my advise stay on grass all the time with the hose when needed.This is not the color I wanted for my lawn. This color is not good even to patch any dead grass because your lawn going to look like two color.Bad color for me.

It does work BUT…..
The drying time printed is not correct. It appeared to be dry and felt dry but as the day got more humid, everyone’s shoes turned green. The morning dew, it was like I just applied it. When it is dry, it still rubs off on you or your clothes. The good news is it washes off with Dawn Power spray.

Works
Pretty good stuff, I mixed it a little stronger than recommended, I was using it for dye marking so I knew where I'd sprayed the more expensive product I'm using (and it doubled as a way of seeing how contaminated I got) and well... it works. It was a little harder to see the difference when I was spraying at dusk after work but it's very obvious in the sunlight. Left side of the photo is treated grass, right side is not (I'm not spending on the council property lol)
