Can Anyone Recommend a Sealer for MDF?
I'm re-painting some window sills in our home. They are made of MDF. The previous owners had applied latex paint. There were deep brush marks so I had to sand quite a bit, exposing the bare MDF in some areas. I primed with Benjamin Moore Superior Fresh Start primer and then painted with Ace Cabinet and Door paint. The spots where the MDF was exposed show through the paint as slightly raised areas. Before I painted, I called our local Sherwin Williams store to ask if I should use an oil primer but they said water based would be fine and wouldn't cause swelling.
I researched some threads on painting MDF and came across one that said MDF needs to be sealed before primer is applied. Can anyone advise as to what type of sealer I should get? Thank you.
