I purchased Rustoleum latex acrylic paint and it runs down the surface

How can I "thicken" this paint? I had to re-sand and prime again because the Rustoleum paint was so thin. I bought it from Home Depot and when I asked them how to thicken the paint, no one there knew. :(

    I would return the paint. Latex paint should not run down a wall.

    I used a new can a couple of days ago, and it was like pudding at the bottom of the can. Not Rustoleum, but maybe your paint needed to be stirred/shaken more than you thought - mine sure did!

      Thanks for your reply. No, that is not the problem. I stirred the paint really well with my stir stick and the paint was still thin. :(

      I usually buy Behr latex paint, their paint is wonderful to use. It comes out of the can nice and creamy and glides on the walls.

    Can't thicken it. Did you stir it good enough. Paint solids tend to settle on the bottom of the container. You need to stir it well to get the solids to mix. Even newly mixed paint from the store will start to settle within 24 hours. A sweeping motion from the bottom of the container to the top will mix everything together and should start to thicken.

      Hi William,
      Thanks but no, that is not the problem. I stirred that can of paint very well with my handy paint stick. No residue at the bottom of the can but the paint is really thin. Not happy about that!

    They will put a can of paint into the paint shaker even if you don't add color to it. It's easier than trying to stir it if it is really separated.

    I don't know if you have time for it, but I've found leaving it in the garage for a few years thickens it up nicely! Maybe if you leave it open at a time when you can stir it frequently it will dry out a little. When I have to buy new paint, I miss how thick the old stuff in the garage is.

      Thanks Brenda. It is black paint so it made a mess on my floor. Luckily it came off easily. Appreciate your input. :)

    I have never been disappointed with Rustoleum call the company, they will tell you what to do with the paint.

      Hi V Smith,

      That's a good idea! I will look into doing that. Maybe they can send me some kind of additive to thicken it.

      Thanks!

    Still thin after stirring I would return the paint where you bought it. Could have been a bad batch from the manufacturer.
