Use the wood filler to fill in all the holes so they don't show threw once you paint it.. Once u have filled them in take a putty scraper to level out your holes.
I used a metal ruler because I wanted to save some cash..
I suggest doing 3 coats of primer if you have more damage on the furniture.. Give it long enough time to dry..
Once the pieces are completely dry sand them down lightly to hide brush marks and fix any drips
Once that's done you are ready to spray paint.. Use the spray paint outside or in a well ventilated area.. I live in an appartment so I'm spray painting on my balcony..
