We are repainting our exterior window sashes and trim. My husband and his DIY brother keep telling me you don't NEED to paint over the oil-based primer. So don't worry about it!

I know this isn't right but don't have the facts to win them over to the idea of slapping on at least one coat of paint.

Any paint experts out there who can tell me why paint is better than primer? I've been telling them it provides protection and sealing that just primer cannot.

Yes you need to apply finish paint over the primer. The prime has no mildew resistance, is NOT made to be exposed to direct weather and most primers are designed to painted over within 30 days. The primer is made to seal and provide a base for the finish to stick to.

So tell your husband to get with it and apply a coat of finish paint over that primer. The finish paint of choice will acrylic latex house paint as it will provide the longest live.

If primer could be used as finish paint and finish paint could be used as primer, why do you think paint companies make both?
