How to Paint Behind a Vertical Radiator?

Published in Painting Tips 3 mins read

To paint behind a vertical radiator effectively, preparation and the right tools are key.

Steps for Painting Behind a Radiator

  1. Preparation is Key:

    • Clean the Area: Wipe down the wall behind the radiator to remove dust and dirt. This ensures the paint adheres properly.
    • Protect the Radiator: Apply painter's tape (also known as masking tape) carefully to the edges of the radiator and any valves or pipes you want to protect from paint splatters. Ensure the tape is firmly pressed down to prevent paint from bleeding underneath.
    • Protect the Floor: Place a drop cloth or old sheet beneath the radiator to catch any drips.
  2. Choose the Right Tools:

    • Angled Brush: An angled brush is essential for reaching tight spaces and corners. A 1- or 2-inch brush is typically sufficient.
    • Radiator Roller (Optional): Some radiators allow enough space to use a small radiator roller for broader coverage.
    • Paint: Use a high-quality paint suitable for the wall's existing finish. Consider a paint with a satin or semi-gloss finish for easier cleaning.
  3. Painting Process:

    • Apply Paint Carefully: Dip your angled brush into the paint, removing any excess.
    • Cut In: Carefully paint along the edges of the radiator, using the angled brush to create a clean line. Work in small sections to avoid drips.
    • Fill In: Once you've "cut in" around the edges, use the angled brush (or radiator roller if space allows) to fill in the remaining area behind the radiator. Apply thin, even coats to prevent drips and ensure proper coverage.
    • Second Coat: Allow the first coat to dry completely according to the paint manufacturer's instructions. Apply a second coat if necessary for full coverage.
  4. Finishing Touches:

    • Remove Tape Carefully: Once the paint is dry to the touch, carefully remove the painter's tape. Pull the tape away from the painted surface at a 45-degree angle to minimize the risk of peeling paint.
    • Clean Up: Clean your brushes and rollers thoroughly. Dispose of paint cans and drop cloths properly.

By following these steps, you can successfully paint behind a vertical radiator and achieve a professional-looking finish.
