…gloss or satin not important it’s for inside of a newly built wardrobe.

mdf has been sealed with MDF sealer.

What do you recommend ? One coat stuff

thanks in advance

In the proper spirit of STW I’m going to say if you think one coat anything is ever the answer then use any old shit as that’s the result you’ll get with any one coat covering 🙂

personally I’d just use a quick dry floor varnish, it’ll be tough enough to last forever in a wardrobe especially after the 3rd coat 🙂
