What are door 'finishes' and which one is right for me?
The finish of a door refers to the door’s surface and there are three types that you can consider: pre-finished, unfinished and primed.

A pre-finished door will be ready to fit complete with either a varnish or paint finish. If you are considering a wooden door there really is a wealth of options available to you, due to the variety of veneers. Oak, Walnut, Ash and Beech are just a few examples or you could opt for a contemporary painted finish.

A primed finish is where a door has been prepared with an undercoat ready for a top coat finish of your choice. It may be that you’re keen to apply your own finish to tailor your door to your design theme.

Unfinished doors are prepared ready for your choice of paint or varnish. One of the rewards for your labour will be that your door can match your colour scheme. Just remember that you’ll need to budget for the purchase of your chosen paint and varnish.
