Preparing your door for paint

Painting your front door involves more than just applying a quick coat of paint.

Before you begin, it is important to remove its hardware, so it does not get covered in paint. Your door’s hardware consists of the knocker, letter box, peep hole, and house number.

People often ask if they should remove the front door from its hinges to paint it. The answer is, you can, but if you want to know how to paint a front door without removing it, you can easily cover its hardware and hinges up with some masking tape.

Next, clean your door. Sugar soap is a great way to remove dirt, grease, and stains without damaging the wood.

If you make a mistake later and need to know how to get paint off front door hardware, wiping it quickly while wet with a damp cloth works best.

If you find there is a build-up of algae, we recommend you use an algae remover for the best results.

One of the first steps of prepping your front door for painting is to sand it down. Wrapping a sheet of sandpaper around a block can help you keep a firm grip.

When sanding, you should always sand in the direction of the woodgrain to help maintain a smooth surface.

If your door has never been painted before or it is bare wood, using 100 to 120 grit sandpaper is your best bet. If your door has been painted before, lightly sand it down using 180 to 220 grit sandpaper. Or, if you would prefer, you can use a sander.

If you are looking at how to paint a composite front door or how to paint a uPVC front door, do not sand it. Cleaning it with soap and water is all it needs before a prep coat. The same approach applies when painting a fibreglass front door. If you were hoping to achieve a matt look, apply a layer of primer and let it dry before you begin your painting project.

Priming and undercoating

A prep coat is a vital stage in the painting process as it helps to prepare your door for its topcoat of paint, and it helps the paint adhere and last longer.

Before you begin applying your prep coat, make sure you have wiped down the door to prevent any dust, dirt, and wood shavings from mixing with the paint.

A prep coat is achieved by using a primer. Oil-based primers are great for darker colours; however, water-based primers are more weather-resistant.

An undercoat is a great way to prepare your door for a paint job as it enhances the colour you have chosen. You should apply two to three layers of undercoat paint while sanding gently between coats for maximum effect.

We recommend using a sealer to cover any unseen gaps or cracks in the wood. Sealer can also create a water-resistant layer between the wood and the paint which is ideal for front doors that have to withstand harsh weather conditions.

Choosing a colour and painting tips

Choosing the right front door paint colour takes some consideration. Natural colours help to create a calm and tranquil feeling. On the other hand, bright colours can create a wow-factor.

Wondering how much paint you need to paint a front door? A standard 750ml tin is usually plenty for two coats on a single door.

When painting, make sure your paint strokes are in the same direction as the wood grain.

If your door is bevelled, it helps to start in the difficult folds and creases before one smooth stroke at the end.

Remember not to overload the paint brush to avoid unwanted drips.

If you are painting a front door with glass panels, you will need to use masking tape carefully around the glass edges.

Semi-gloss paints are a popular choice for painting front doors. Like with primers, there are two main types of paint: oil-based and water-based. It’s important to match the type of paint to the kind of primer you used. For example, if you used an oil-based primer, make sure you use an oil-based paint and topcoat too.

Once you have finished your topcoat, many DIY-ers like to add a clear varnish. While this is not a necessity, it provides an extra layer of protection against outdoor conditions.

FAQs

The best time of year to paint your front door is spring or early autumn. Direct sunlight and high levels of heat can dry your paint too quickly and make it harder to achieve a smooth finish. You should also avoid wet weather.

Paint usually becomes touch-dry in a few hours. However, drying and curing times for exterior door paint can vary. It can take up to a few weeks for the fresh paint to fully cure and harden against the elements.

If you include time for cleaning, sanding, and allowing your primer and two topcoats to dry, you should set aside a full weekend to complete the project without rushing.
