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.
You want to accomplish a very uniform application of about 0.03 to 0.05 gal/sy of residual asphalt on the layer to be tacked (a paint job, so to speak). Slow-setting emulsions generally have a residual asphalt content of about 2/3. Therefore, an application rate of 0.10 to 0.15 gals/sy of the diluted material will give you the 0.03 to 0.05 gals/sy. Caution #1: Once the tack coat is applied, time must be allowed for emulsion to break (turn from brown to black) prior to placing hot mix on it.
