In what order do I paint a wooden door?
This will depend on what type of door you have, but a general rule is that you start with the top and bottom edges followed by both the long edges. Then start at the top and work your way down to the bottom.

How do you prepare a wooden door for painting?
There’s a few steps you need to follow to get a wooden door ready for painting. If you have bought a new door and haven’t hung it yet you should paint before you hang. This gives you access to all edges of the door – such as the bottom – which you don't have when a door is hung in position.
One tip to get the best finish on the hinge edge is to hang the door and then take it down. This allows you to paint the hinge recess, rather than cut out the hinge recess after you have painted. If the door is already in place, look to take down to paint if possible. Remove any door furniture and mask off any glass panels with painters tape like ScotchBlue Multi-Surface Premium Masking Tape from Amazon.
To paint a door you need a couple of trestles like the Evolution Compact Folding Saw Horse from Amazon. You can lay across and paint one side and edges, leave to dry and turn and paint the other side.
But one trick to speed up the process is to put a couple of screws in the centre of the top and bottom edge of the door and place them on each trestle. This allows you to spin the door so you can paint all edges and sides without having to wait for one side to dry. A tip is to add an extra screw in one end to hold in position when painting one side. Then remove the extra screw, flip the door over and replace the screw.
Whether you are working with a new door or a previously painted door you will need to sand to give better adhesion for primers, undercoats and top coats. You can do this by hand or with a sander like the BLACK+DECKER 55 W Detail Mouse Electric Sander from Amazon. Check out our sanding doors guide for an indepth look at the process.
Do I need to prime a wooden door before painting?
Yes and no. If you are painting a new bare wooden door or one where you have had to strip paint off the wood , you need to start out with a decent primer like Zinsser 123 Bulls Eye from Amazon. This is suitable for interior and exterior doors, is quick drying and seals knots to stop any sap seeping through and spoiling the surface.
If you are painting a previously painted door, which hasn’t been sanded back to bare wood, then typically there is no need for a primer, you can start with an undercoat. However, if you are painting a light colour over a dark colour you can start with a coat of primer to help cover the colour.
What kind of paint do you use on a wooden door?
Doors are prone to a lot of wear and tear so you need a hard-wearing and durable paint for the finish, which is why it is very often a choice of satin vs gloss. Gloss has a higher sheen than satin, but it is more reflective so it is more prone to showing up any imperfections. Both are wipe clean, but gloss has a slightly harder wearing finish, so can be washed more often, though there is not much in it.
Gloss and satin are both available as water-based or oil-based paints. Water based paints such as Dulux Trade Quick Drying Satinwood from Amazon dry quicker than oil based paints, are ready to recoat sooner, are more environmentally-friendly and it's easier to clean brushes and rollers. While oil based paints take longer to dry and harden, they have a more durable finish and offer greater coverage.
How long will a wooden door take to dry?
This depends on what paint you use and how you apply the paint. Water-based paints dry quicker than oil based paints, but how long can differ from brand to brand. But as a general rule expect water-based primer/undercoat/satin/gloss to be touch dry within an hour and ready to recoat in around four hours.
Oil based paints take longer to dry due to their make up. They are typically touch dry within three to four hours and ready to recoat in 16-24 hours.
To get the best finish follow the manufacturer's recommendation on drying times. Applying a new coat before the previous coat has dried properly will weaken the structure of the paint making it more susceptible to damage.
It is a good idea to leave the paint to cure (harden) for at least 24 hours before you rehang a door. Check out our how long does paint take to dry article for a closer look at drying times for different paints.
