    Are you using a paint made specifically for porches that will resist wear and outdoor elements?

  • Be sure to scrape ant loose paint and then sand smooth. Since it's outdoors, be sure it's dry before painting.

    Scrap it, sand it, prime it, and use outdoor paint two coats.

    A variety of issues could be at play here. First, you should determine whether moisture is coming up through the concrete from below. Tape a piece of relatively thick, clear plastic, such as a three-inch square cut from a reclosable plastic bag, to an area with no paint. If moisture droplets appear over the next day, you’ll need to strip off all the paint and switch to a coating that resists hydrostatic pressure. Rust-Oleum’s WaterTite-LV Waterproofing Concrete Masonry Paint is one example. Or you can coat the stripped surface with a concrete-resurfacing material, such as Quikrete’s Concrete Resurfacer, which can be tinted.If no moisture beads form, a suitable paint should stick, provided it is properly applied. You or your painter needs to scrape off all loose paint and scuff up what remains with 100-grit sandpaper. Wipe off the sanding dust with a damp rag, then clean the concrete with a cleaner-degreaser, rinse and allow to dry. Coat all areas of bare concrete with a suitable primer, such as Behr Concrete & Masonry Bonding Primer. That needs to cure at least eight hours. Then you can paint with a product designed for exterior concrete, such as Behr Premium Plus Porch & Patio Floor Paint.
