## Description

Homax Paint Hardener is an paint management solution that turns liquid paint solid for curbside disposal. It quickly hardens latex and acrylic paints and stains so you can dispose of the solidified paint safely. You save time and effort than painting out or drying up and there is less mess too. No need to use newspaper, kitty litter, or sand. One 3. 5 oz. package hardens up to 2/3 of a gallon (2. 5L) in 15-20 minutes.

Review: Works great - I wanted to get rid of 3 gallons of old paint in a 5-gallon bucket. I used 4 bags of Homax 3535 paint hardener and spent 10 minutes mixing it into the paint. It began hardening almost immediately and the entire 3 gallons had solidified by the next day. This stuff works great and allows me to properly dispose of paint.
Review: Great way to get rid of your old paint. - We have no paint recycling available to us. I had around 20 cans of paint of various sizes that have accumulated from projects and room makeovers that my wife thought I- I mean “we” should do. I considered putting a can of paint in each of my neighbors’ trash bin at 4am, but my environmental morality mixed with the challenge of tactically moving down the alleyway with multiple cans of paint without starting a neighborhood dog barking festival prevented this option. I then discovered Homax paint hardener. Easy to use, easy to dispose. With the aid of my 12 year old son, we were able to easy harden the paint and he was able to get paint on the right side of his clothes. Not only was my wife excited about the disposal of “her” paint, she was super pumped about the redesign on our son’s clothes. Some things we learned along the way: 1. Latex gloves, cardboard, scrap paper, disposable paint stirrers, and trash bags will make this a simple process. 2. Layout some scrap cardboard as a work surface. 3. Slowly and incrementally pour the hardener into the paint while stirring the paint. Be sure to scrape away the paint from the sides and bottom of the can as you stir. 5. Once you get a thick oatmeal consistency, dump it onto scrap paper and let it set for around 15 minutes. 6. After it hardens, dispose of it into the trash if you have no prohibitions against it. 7. If the thin layer of paint is allowed to dry on the sides, it can be pealed away. 8. The empty paint cans are able to be recycled. My garage is now free of all the old paint cans. Thanks Homax.

## Questions & Answers

**Q: will this harden varnish?**
A: Hi there, this product would not work for a varnish.

**Q: I have 2 quart cans am  I able split one envelope for both can?**
A: If one envelope is designed for a one gallon paint can, one envelope should work on up to 4 one quart cans (@4 quarts per gallon).  Good luck.

**Q: one month ago I paid $2.34, planned  to buy more & they are $7.65, why did the price more than triple in one month? Is there more than 1 in the pack?**
A: WOW that is ridiculous!  I don’t know, you’ll have to read the description. It should tell you if it is one pack or multiple packs.  Hopefully there are multiple packs for that price!  Inflation is out of hand!

**Q: Does the paint get hard or just clumpy?  I used a pack on 1/2 gallon of paint and it make a semi-dry mushy mix.**
A: This product should solidify the paint, as long as it’s properly mixed.
