Sunnyside Corporation 79205M M-1 Waste Paint Hardener, 4.7 oz, (Pack of 6)

Inherited a ton of old unusable paint. Cat litter didn't cut it, so I spent a fortune for packets of this gardener so we could throw the paint out as a solid. One packet per gallon--some hardened as advertised, but some didn't. Not sure why. Ended up adding more packets, then more cat litter and spreading it out on papers to dry. What a pain. All were latex paint.

Good stuff. Hardened the old paint quickly so we could dispose of it.

I’m moving and need to harden paint ASAP to dispose of. Now I have to return and request replacement and WAIT for the proper amount I originally ordered. It seems this has been a problem for other customers based on reviews.

The paint hardener was good. Did an acceptable job with my old paint. Must remember it only works with latex type paints and seems a little pricey to me. With a full gallon it requires at least two bags. At least for me.

I received 6 pouches as expected and added 4 to two-thirds full 4 gallon (18 l) drum of paint. Within an hour it was solid. Easy to use. I might have even overdone it a bit as I might have only needed 3 or 3.5 pouches. Job done.

Like the other reviewer, I also recieved only one package. Sent it back and they quickly fixed the problem and I got all 6 packages. Had several cans of old paint that were quite full. We can only dispose of paint if it is hardened. This did the trick nicely. Turned it to concrete! Half a package worked well for partial cans. This is the only one I know of that will hardened up to a gallon of paint.

Price was for a package of 6. Keep getting just 1 packet per shipment

Didn’t think it would work. But it did!!!
