With a jointing knife in hand, you can start to get your plasterboard ready to paint. Run the knife over every joint and pay special attention to areas where the plasterboards are not level or the fixings are sticking out. Be sure to use the correct size screws to secure the boards and countersink the screws to indent the plasterboard. try not to tear the paper, as this can cause issues with the filler ‘blowing’.

Mix joint filler

Using ajoint filler, make a mix according to the manufacturer's instructions. Use the knife to scoop out some filler, and run it along each joint in a smooth motion. Use the knife to smooth out every joint and fix it. Use a shallow angle and scrape off any excess filler and then sand it smooth when dry, using a fine-grain sandpaper.

• Painting directly on new plasterboard: In a standard room, you can wash out the plasterboard with a damp cloth, this will remove any dust, fluff and other particles to give you as smooth a look as plastered walls. A good top coat of paint with a sturdy roller and some finishing may be all you need.
• Painting plasterboard in a bathroom: When painting plasterboard in the bathroom general tips include taping and finishing any areas near tiles by hand, to keep the appearance of the tile straight and even - as well as to camouflage the tile adhesive. You can use waterproof paint here, or you can use amoisture-resistant plasterboard.

By using a watered-down emulsion you can apply a mist coat using your emulsion paint.
