Once you hire a professional painter and decorator, you’ll want to follow some simple tips to ensure your freshly painted space is maintained. These include: Cleaning your walls: Gently clean your walls with a new sponge soaked in a water and soap solution. Then, cover the areas using a towel to dry the cleaned surface. Dust your surfaces: Occasionally dust your walls and ceilings with a dust cloth to keep your interior paint job looking pristine.  Ventilate your home: Keep your home regularly aerated to prevent mould growing on your interior surfaces. Following these simple steps will help to ensure your interior paint job lasts.
