I saw a new product ? today at HD called paint hardener. It’s a powder in a small package.
It’s used when you have an old gallon of paint you want to throw away.
You add the hardener, the paint hardens, and it can then be tossed out with the rest of your regular household garbage and it’s okay if it ends up at the landfill.

It's gonna be tough to get me not to pour that old paint on the ground in order to dry before tossing. A bit cheeper.
I've tried it. It works quite well, but it is expensive.
Usually, I only have a little bit of paint left that I need to get rid of. I mix in a bunch of cat litter, wait till it dries, and toss it in the garbage.
Good, cheap solution. Gets even cheaper if you use "used" litter.
Dries even faster if you dump the resulting slurry onto a plastic trash bag and let it sit in the sun for the afternoon.

Never underestimate the value of a sharp pencil or good light.
In Vegas, they collected it at the recycling center, and mixed all the paint they got together, into two colors, a light tanish grey which seemed to match brown toned block walls, and a cinder block grey that matched the concrete grey block walls. They used this to paint over graffiti.
That sounds like a great idea. Here in Jersey, they treat it as hazardous material. You have to make an appointment to dispose of it, it has to be in the original containers, they will take only 5 gallons at a time (a nearly empty gallon can counts as one gallon), and it has to be hauled to a single collection center. One for each county. And, of course, 9-5 M-F.I suspect that this policy results in a lot more paint being dumped down the drain or into the local stream than would otherwise be the case. They used to recommend that you combine partially empty containers, but now they have this "original container" clause, and it just ain't working. Hurray for the Home Depot stuff.George Patterson
We use it all the time only we call it Sakrete. If we're out of Sakrete we'll use old joint compound or plaster. They all work just fine.

You got it!
You're good. I can usually guess those things but that one stumped me.
Sounds like Krud Kutter ...

got a local HD & never seen this.
Does it harden the paint faster than the "leave off the lid"?
Suitable for alkyd as well as (I assume) latex?
I saw it yesterday at the counter at the paint dept.The product is in a small display which sets on the counter. There was no price on it.Beside the display is an open can of old paint they use as a demonstrator.The dried paint looks like rubbery granuales similar to cat litter.The display can of paint was latex and I assume the product will work with oil base paint and any other type of paint.I have stuff in my garage I want to get rid of. For example an old gallon of anti freeze.Some of this stuff you can't take the lid off and let it dry out. I'm going to try some of the things mentioned in this thread, such as cat litter, powdered sacrete concrete, etc etc.I've got an old gallon of thompsons water seal I need to get rid of.I'll try just opening the lid - but it's so thin it would take forever to dry up to a solid. I'm guessing.^^^^^^

This stuff is just cat litter and they bump the price about 50X for packaging. I just mixed up a 5 gal bucket of various leftover cans of old paint with $1.50 worth of generic cat litter. Dried up in 2 days and it was out with the normal trash.

This stuff is just cat litter...
No it's not. I've used both. Cat litter absorbs the paint. It works well, but it requires a fair amount of cat litter. Maybe a 50/50 ratio. Paint hardener hardens the paint by a chemical reaction and only requires a small amount. Less than a cup per gallon.
It only works on water-based paints and it's expensive so I rarely use it. Mostly I just use cat litter.
The stuff I bought (not at HD) works only with water based paints.George Patterson
