A fresh coat of paint is an easy way to keep the trims around your doors always looking their best. We'll show you how to prepare them for painting, plus how to apply the undercoat and topcoat.


1Put down drop sheets

Put down a drop sheet to protect your floors. Take off the doorstop and fill any dents or holes with putty. Give the trim a light sand. Then use a cloth to clean off any dust before you start painting.

2Tape around the trim

Put tape on the wall around the trim to prevent getting any paint on it when you're painting.

3Stir the paint

Stir your paint well before you use it. Make sure your room is well-ventilated and wear your dust mask.

4Pour some paint into a smaller pot

Pour some paint into a smaller pot to make it more portable and easier to manage when you're up a ladder.

5Apply the undercoat

Make sure you've got a good quality brush to paint with. It's a good idea to paint your edges first and then your flat faces. Use long strokes of your brush, working from the top down to the bottom. Work in small sections and make sure all areas have equal coverage.

6Leave to dry and sand

Let the undercoat dry and then give it a light sanding before applying the topcoat.

7Stir the topcoat

Stir your topcoat paint and pour some into a small bucket to make it more portable and easier to use while you're up a ladder. In this example, we've chosen a semi-gloss enamel for the topcoat as it's very durable.

8Apply the topcoat

Apply the topcoat in same way as the undercoat. Start with the fiddly bits and edges first. Work in long strokes from top to bottom. Then wait for the paint to dry before peeling off your masking tape.
