Thread: How to remove house paint from concrete?

My class buys house paint to paint posters, and it has gotten stained on the school's conrete, so I was wondering if there are any products to remove it in a safe and simple way? So far I've looked upon CitriStrip, but I heard it takes awhile to remove, and sort of smells? And I've also heard about Klean-Strip, but the products looks toxic and difficult to use...? Help, please?

Just get a high pressure washer and blast it away!

paint thinners and a yard brush

Water, wire brushes and lots of elbow grease. Give the poster painters a wire brush and tell them to get to work.
