MDF sometimes comes pre-primed, but if yours isn't, then you should prime the surface before painting. You can use any type of water-based primer, such as an emulsion paint or an acrylic primer.This base-coat of primer will help give the top coat a truer shade and will prevent it from being affected by the color of the board. do painting of mdf all the time. Water based undercoat is fine but i prefer two coats. then i use eggshell, oil based finish once. that should always be enough.
Report Abuse. I'm assuming you are using flat LATEX paint. I will also assume you've primed the walls before painting. if the above is true, the first coat will be dry in about two to four hours. DO NOT try to paint a second coat, right after the first coat! Wait two to four hours, and put your hand on the wall. Does it feel a bit damp? if so, wait until the next day! If not, then take a sanding pole, with 150 grid sanding paper, and very lightly and quickly sand the wall.
