Overview
Matching paint colour can be tricky. This guide covers how to match paint colour for touch-ups.
Step-by-Step Fix
Safety & Preparation
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- Carefully remove a small, clean chip of the existing paint from an inconspicuous area of the wall or surface you wish to touch up. Take this paint chip to your local DIY store or paint specialist, explaining that you need to colour-match it for touch-up purposes. The staff can then use their professional colour-matching equipment to identify the closest paint shade available, usually from their own stock or by mixing a bespoke colour.
- Download and open a reputable paint colour matching app on your smartphone or tablet, ensuring it's designed for paint identification. Hold your device's camera steady and flat against a clean, undamaged section of the existing paint, making sure there's good, natural lighting without direct glare. The app will analyse the colour and suggest corresponding paint codes or brand shades; note down the top 2-3 recommendations for purchasing.
- Before applying any paint to the visible damaged area, always test your chosen paint on an inconspicuous spot, such as behind a large piece of furniture, inside a cupboard, or on a spare offcut of the original plasterboard if available. Allow this test patch to dry completely for at least 24 hours, as paint colours can change slightly when dry. Once dry, compare the test patch to the surrounding original paint under various lighting conditions to confirm it's a good match.
- If your initial test patch doesn't blend seamlessly with the existing paint after drying, you'll need to try an alternative shade. Revisit your paint supplier or app results, focusing on the next closest options, perhaps slightly lighter or darker, or with a different undertone (e.g., warmer or cooler). Always purchase the smallest available quantity of these new shades and repeat the crucial 'test on a hidden area' step before committing to painting the main touch-up spot.
