hi I have some old internal doors which I would like to paint, they have what looks like some laminate style finish (high gloss finish), what's the best way to prep the door before painting. these doors are about 40 years old
Hi David, thanks for your question.
In the event of not being sure whether or not the doors have a laminate finish, we’d typically recommend you start by giving them a good sand with 120 grit sandpaper. This should give you a good indication into whether or not they are indeed laminate doors.
If they are a prefinished laminate type product, you’ll find the sanding step won’t work very well. If that’s the case, you’ll need to use a high adhesion undercoat such as the Dulux Precision Max Adhesion Primer or Zinsser Smart Primer. This will help the paint stick to the wall.
After this, all you would need to do is apply a regular paint such as Dulux Aquaenamel or Super Enamel.
If they’re not laminate doors, then simply finish going over with sandpaper and apply an all in one undercoat or primer sealer undercoat.
It’s worth noting here that any water based finishing coat takes 3 to 4 weeks to fully cure.
If the surface you’re sanding powders up and the area goes dull, then you know the sandpaper’s working. This means it’s doing its job and you’re going to get good adhesion.
Regardless of what paint project you are tackling, we always recommend heading in to your nearest Inspirations Paint store to discuss the finer details of your paint project. They will make sure you get the job done right the first time and will help minimise and potential unexpected mishaps from occurring.
Hope this helps.
