Choosing Your Paint

Which Paint, Where?

  • There are two types of paint: water-based or solvent-based. Your choice depends on the area you’re painting.
  • Water-based paints are popular for most walls and ceilings. They’re easy to apply, are touch dry in 20 to 30 minutes, can usually be re-applied in three to four hours, and you can clean up in water.
  • A semi-gloss or satin finish acrylic gives a hard surface in high traffic areas such as kitchens, family rooms, or children’s rooms where frequent cleaning is a must.
  • Flat or low sheen acrylic or vinyls are commonly used for more formal, less frequented areas like dining rooms, bedrooms and lounge rooms where the matt finish suits the atmosphere.
  • For ceilings “Ceiling Whites” are highly recommended. They are ultra flat in sheen and mask surface imperfections.
  • If in doubt, our Paint Department will help you decide the best paint for your surface.

How Much Paint?

  • For flat areas like ceilings, walls and doors just multiply their length by their height, subtracting areas such as windows and door openings. This gives you the area to be painted. To estimate how much paint is needed for frames of windows and glass doors, multiply their width by their height and divide by five.
  • Allow one litre of paint per coat for each 16 square metres to be painted. Add an extra 20% to this quantity for rough or porous surfaces.
Wall Height Distance around the walls (m)
10 12 16 20 24
2.4m 4L 6L 6L 8L 8L
2.8m 4L 6L 6L 8L 10L
3.0m 4L 6L 8L 8L 10L
3.2m 4L 6L 8L 8L 10L
3.5m 6L 6L 8L 10L 12L
Please note: Paint quantity required for two coats and is dependant on the type of paint being used.

Choosing Your Tools

  • Buy the best painting tools that you can afford. Good brushes and rollers, properly looked after, will give years of service, speed up the job and give superior results.
  • The choice of roller sleeve depends on the surface you’re painting as well as the paint you’re using.
    – For water-based paints on smooth surfaces, use a 10mm nap sleeve. For water-based paints on rough surfaces, use a 20mm or 22mm nap sleeve. For extremely rough surfaces, use a 35mm nap sleeve.
    – When rolling on solvent or oil-based paints – use a 6mm mohair nap sleeve or a 5mm foam sleeve.

How To Use Paint Rollers

  • For valuable information on selecting, using and caring for paint rollers and sleeves. Search “How to use paint rollers” on the Mitre 10 website.
  • It’s a good idea to choose a roller with a threaded handle that allows you to ? t an extension. This will take the backache out of reaching ceilings and high walls.

Preparation

Preparation is key and perhaps one of the most important steps when your just learning how to paint interior rooms. A smooth, well prepared base will help speed up the finishing coats, and give you a great result.

New Surfaces

  • You’d be surprised at the number of blemishes and scuffs they can have. So sand smooth, dust off and wash down with sugar soap.
  • Prime timber surfaces before repairing any faults.
  • Check plaster and plasterboard for any nail depressions or cracks and overfill with an interior filler, sanding back to a smooth, even finish.
  • Punch in any nails and fill.
  • Apply undercoat.
  • Use a flexible gap filler to fill any cracks.

Painted Surfaces In Good Condition

  • If there’s no flaking or peeling, wash down well with sugar soap, or interior paintwork cleaner, to remove dirt, grease and smoke stains. If there’s any mould use sugar soap, then treat with an anti-mould preparation.
  • Check for any cracks and overfill with an interior filler. Sand to an even finish.
  • If the existing surface is an enamel paint, sand thoroughly to remove the gloss. Then apply the undercoat.

Painted Surfaces In Poor Condition

  • Scrape away flakes and blisters then smooth with sandpaper.
  • Touch up bare areas with an undercoat or primer.
  • Really bad paintwork should be scraped right back to the bare surface.
  • Then sand, wash down with sugar soap and treat as a new surface.
  • If your wall is in particularly poor condition, it’s a good idea to get a gib stopper in – that way you’ll have the best possible surface to paint. It’s not very expensive, and is well worth it to get a professional looking finish.
  • If you are plastering, your walls will need to be sanded, dusted, then painted with an oil-based pigmented sealer. This gives the plaster something to bond to. So when your learning how to paint interior rooms make sure you’re not skipping this step.

Paint Application

  • If you’re painting a whole room, move all the furniture out if possible. Protect the floor with a drop sheet.
  • Mix the paint thoroughly. Use a paint stirrer and stir from the bottom upwards (not just around) until all the paint is quite smooth and the colour is even.
  • Start with the ceiling, cutting in the edges with a brush (leaving a fine edge) around the scotia (the mouldings which cover the line where the wall and ceiling join).
    – Fill in the main area with a roller, working from the darkest corner of the room towards the light.
    – Work in narrow strips so you can clearly see where you have stopped and started.
    – Paint around ceiling light fittings, then complete the rest of that band.
  • Next, the walls. Start in the corner with a paint brush, cutting into wall edges, window and door frames.
    – Fill the main areas using a roller; in an upwards direction first, moving across the area in a rough “M” pattern before evening out the paint in an up and down motion.
    – Ensure the roller covers the cut in areas before the paint has dried to avoid brush marks and a ‘framed’ look.
  • Paint your skirting and the rest of your finishing lines last.
