Guide on Spray Painting Composite Doors

If you have a tired-looking composite door, one great solution is to paint a composite door and breathe new life into it!

Spray Painting a Composite Door

Over time, your doors can look dated, the paint faded, or the fitments break, and you have a shabby broken letterbox.

Giving your composite door a redo is easy, and composite door spraying is the answer.

Is Spray Painting Better Than Painting A Composite Door?

Spraying composite doors is easier as you avoid potential brush stroke residue, and you won't have to spend money to replace your door, so try spray painting!

Composite door spraying will not only rejuvenate the look of your door but also make you a proudly accomplished DIY project master!

Your new door is a few steps away, and you can change colour every time you change your mind with simple spray painting for a smooth finish and beautiful composite door.

What Do I Need To Spray Paint My Door?

You will need the following:

  • Sugar soap
  • Grated sponge
  • 300-grade sandpaper
  • Masking or frog tape
  • Paint primer (depending on your spray paint)
  • Weather shield multi-surface paint in a colour of your choice
  • DC Fix film for your glass panels (if you want to upgrade the glass look)

How Do I Spray Paint My Composite Door?

Composite door spraying is a lovely DIY project to take on, and with a few simple hints and tips, you will have a brand-new composite door.

UPVC door spraying is not only for professionals, and you can feel confident that once your front door has been sprayed, whether it is dark brown, golden oak or any other colour, your spray-painted smooth finish door will also be the talk of the town!


Door Surface

Start by cleaning the composite door surface with sugar soap, as this will also give you a smooth finish to your spray-painted door once it is finished.

Use flexible sponge sanding blocks with an extra fine grit.

After sanding, ensure that no bits are left and that the door is completely clean by washing it with sugar soap.


Use frog or masking tape around the composite door's letterbox, and protect the area around it with newspaper.

Door Handles

Remove the door handles and varnish. You can also spray paint the door handle with an all-surface spray.

Glass Panel rejuvenation

After properly cleaning your glass panels, you can either keep them as is or cover them with film.

Put frog tape around the glass panels on the doors to protect them before painting a composite door.

If you do plan on putting the film on your glass panels for an upgraded look, be sure to remove all the air bubbles.

A broken glass panel will also mean you will likely need a glass panel replacement for your composite door.

Design your door


Spray painting composite doors is easier when they are removed and laid flat on a surface, but you can keep them in their hinges, given that composite doors are very heavy.

There are different types of spray paint you can use, and one of them is UPVC solvent-based paint.

The process is more or less the same as when spraying wooden doors, but when you paint a composite door, spray paint attaches to the whole door area without bubble residue.

Choosing the colour paint for your doors may be the hardest part of your project. Rest assured the new colour and smooth finish will make you glad you did it!

If you find that you actually don't like the new colour of your composite door and prefer a natural look, you can always try door paint stripping.

Spray painting product options

  • Regular paint will not work for spraying composite doors, so you want to choose a spray paint product, which is a multi-surface paint with a weather shield.
  • You are saving money by not having to replace your door, so you can afford to spend a little extra on the paint product.
  • When you decide to paint a composite door, you most likely won't need a primer, but you do need to use at least two coats.
  • The temperature will impact your front door drying time, so it's best to paint composite doors in temperatures above 10 degrees.
  • The great thing about composite door spraying is that you do not worry about brush marks.
  • Leave the paint to dry for about four hours between coats and appreciate the shine of your finished project and the beautiful new composite door!

If you decide that spray painting your door is too much effort, you could hang a wreath on your composite door to give it a new lease of life instead.
