How to paint Interior Walls

Step 1: Wall Preparation

  • Move furniture and use a drop sheet to cover the floor.
  • Remove any light fittings and switches. If they can’t be removed, mask or cover them.

    Step 2: Washing

    • Stains such a grease, oil, smoke, dirt and dust will affect paint adhesion – so even if your wall is new or looks clean, wash it to ensure a perfect finish.
    • Wash the wall using sugar soap, following the instructions on the packaging.
    • undefinedTo cover and block certain stains, use British Paints PREP 4in1 before applying the topcoat.

    Step 3: Filling

    • A flexible gap filler is recommended for gaps at joins, or in the corners like skirting boards and architraves.
    • A standard interior flexible filler is recommended for hairline cracks, holes and larger gaps on the wall area.Use a fine sand paper to remove any remaining filler.undefinedPatched areas may need three coats of British Paints Clean & Protect.

    Step 4: Sanding

    • Protect yourself with safety glasses and a dust mask.
    • Apart from bare plasterboard, almost every surface must be sanded before painting.Small areas can be hand sanded but a pole sander will help save time. Always dust after sanding.undefinedDon’t push too hard when sanding, let the grit do the work.

    Step 5: Application

    • For previously painted surfaces, apply two top coats of British Paints Clean & Protect.
    • Begin by cutting in the edges with you brush, one wall at a time.
    • undefinedPatched areas may need three coats of British Paints Clean & Protect.
    • Start rolling in an M pattern, moving from one side of the wall to another – never start in the middle.
    • Each time you finish a 1-2 metre section you need to lay off your paint. Do this by rolling the roller without loading it up with paint from the top of the wall to the bottom in one straight stroke.Then continue along the length of the painted wall taking care to slightly overlap so you don’t cause streaks.So your finish isn’t patchy, it’s important you maintain a wet-edge and complete the entire wall before stopping.
    • Allow at least two hours drying time before applying a second coat.
