Basement Floor Paint

My basement remodel is 90% complete. One last task is to paint the section of the concrete floor that will remain exposed. The concrete has 3 layers of paint on it in varying conditions. My plan was to prep by scraping/wire brushing the surface and then scrubbing with TSP, followed by a good rinse. I do not want to get into stripping all the paint and etching the surface, as this is a large area in a basement.

Are there any flaws in my prep plan?
What coating products would work well for this purpose?

Thanks!

I'll let someone else comment on the paint since I've never done that.

I always use a good commercial water based clear sealer. Easy to install, really seals good and looks good for years.

Do you know what type of paint is currently on the concrete? http://www.doityourself.com/forum/pa...latex-oil.html Latex floor paints don't always adhere well over oil base floor paint.

The only time you need to etch concrete prior to painting is when it has a slick finish, an acid wash will open up the pores so the coating will adhere better. Etching does nothing over paint. Be sure to rinse the TSP well as paint doesn't always adhere well to TSP residue.

If all loose paint is removed, would an epoxy coating work in this situation?

It depends on the epoxy. You'd need to read the label! Some can be coated directly over existing paint, some need a special primer and a few need to start off with a raw/bare substrate.

Understood. Can you recommend a product for my situation? I've read positive results for the Rustoleum Epoxy product.

I haven't painted a basement floor in a long time. Don't recall ever using a Rustoleum Epoxy.
