Painting Internal Wood Doors

Although Thorndown Wood Paint is specifically designed to stand up to the rigours of external timber protection, it is also the perfect wood paint to use on internal woodwork such as interior doors.

Being water-based with minimal VOC and low odour it’s a pleasure to use especially when you’re painting inside and don’t want to be knocked out by fumes for days on end.

Thorndown Wood Paint is hard-wearing and highly water-repellent so you can clean it down without affecting the coating. This also makes it great to use in areas of high moisture such as bathrooms and kitchens.

We use architectural exterior-grade VOC free colour pigments in our paints so the colour remains strong and true for up to 10 years.

Painting your interior doors with our wood paint is simple and quick. Here’s a check-list to help with your painting.


  1. You can overpaint old coatings. Sand back any loose coatings and fill cracks with a flexible filler such as caulk. Make sure it’s one that’s easy to overpaint with a water-based paint
  2. Clean the wood work with soapy water and leave to dry thoroughly
  3. No primer is required as the resin we use is self-priming. However if you are painting a metal or uPVC door then use a multi-purpose primer
  4. If you are painting a new wood door then you may want to use a stain-blocking primer or knotting agent to block any resin bleed or tannin staining the new paint coating. On darker colour paints tannin staining isn’t so noticeable
  5. Get your paint, roller or brush, cover the floor to protect from drips and you’re ready to go


  1. Use a paint roller, brush or sprayer and apply paint working methodically, painting with the grain. Paint up to neighbouring wet paint until you’ve finished
  2. Leave to dry for 1-2 hours before applying a second coat
  3. Two coats is all you need for full protection. On lighter colours such as Swan White a third coat will increase the intensity and solidity of the colour coating. You can apply just one coat
  4. Allow to dry for as long as you can before closing the door. Although the paint will be touch dry it will need hours to fully fix so leave it as long as possible. If you close the door before the paint has fully fixed then you risk it sticking to the door frame
  5. Wash your utensils with water, put the kettle on and congratulate yourself on a job well done

These doors were painted with RAL 7016 Anthracite Grey wood paint to match the rest of the interior design, looking very striking and chic.

When Is A Door Not A Door? When It’s Adoorable!!

Every house has a number of doors and they can all just blur into one. Every door the same old style, with the same old paint.

Well we like to have fun with our doors and have painted some up with decorative design details and stencils. The doors were painted with Swan White Wood Paint with stencilling and detailing in other colours to bring them to life.

A simple trick is to paint the edge of the door in a contrasting colour or a colour from the room that it leads into or out of. We also love stencilling as it can be a fun and easy way to inject some interest and design elements into otherwise pretty dull areas.

In the bathroom I used a simple anchor stencil from one of our favourite collections by Ed Roth. It is painted in the same Cavepool Grey Wood Paint colour as the door edge, door knob, bathroom panelling, shelves and even the loo seat.

It takes minutes to do and helps create an attractive and unified design.

On this bedroom door I combined a couple of stencils from the same Ed Roth collection with some stencil designs from an old interior decorating book. Colours used are Bishop Blue and Peregrine Blue to contrast with the wall colours.

I love the way these designs add a soft, feminine feel and integrate the door with the colours and décor of the rest of the room.
