Urgent question!! Latex exterior paint over Duron Maxwood stain
We are having wood siding painted on the house and the contractor and I are arguing over which paint to use. Right now the siding is painted in Duron Maxwood acrylic. It was painted 4 years ago and it already looks bad because of thinning of the paint and some cracks.
I wanted to do 1 or 2 coats of Duration latex paint on top of the Duron Maxwood but my contractor said within months the latex paint will start to peel if latex is put on top of oil. He wants to use SherwinWilliams woodscape.
Is he right? For long term purposes which is better? Latex paint or oil solid stain? Thanks so much!!
