I call upon the vast knowledge of arfcom to help me answer this question.

I have some chips in a concrete floor that I need to fill before I lay down my garage floor epoxy. Every self leveling filler I find does not mention anything about being paintable.
Can anyone help as I would like to get these chips filled today so I can epoxy tomorrow or monday?

Thanks for your time

Put your filler in... it is just like any other concrete.

? Did you read the question?

Which filler is paintable

Most self-leveling fillers are soft and chalky, not paintable.  Use a hard patching compound, a good sand-portland mortar is good.  Clean the chips out, pickle with a bit of dilute HCl, then flush with clean water.  Patch wet, keeping the patched area damp by covering it with plastic film overnight.



Don't waste money on self-leveling mix, this is for under floors, not for painting.

I'd just use the normal Quikrete mortar mix.

Did a few hundred thousand square feet of concrete floor a few years ago with epoxy plaint at the plant I work at. We used an epoxy type patch for cracks/chips in the floor. It worked well and the paint binds nicely to it. Especialy if you properly prep the surface before painting.

How do you plan to prep the floor for paint. I've found that this is the key to success. I've tried etching with acid which had mixed but decent results. I've found that shot blasting does best.

Do you remember what epoxy patch you used?

I plan to vacuum and wash the floor. After it dries I will use the concrete prep that comes in the kit.

Epoxy would work fine, just expensive unless you only have a few.

I would give a few days for curing before you paint if possible.

Edited to add, for cement based products.  For epoxy based patch products, 24 hours should be fine.

I used bondo on the big chips in my floor before painting it with the epoxy garage floor coating. Let it dry a while though, and use the clear cement primer on top of everything before painting.

Trust me on this... for half of your mixing water substitute Elmer's glue.  Yes, white glue.  This is known as "latex cement additive" and helps your patching bond well to the old cement.
