Prepare perfectly before painting
A fresh coat of paint will transform any room, and the satisfaction you will get from doing the job yourself lasts long after the paint has dried. But before you start painting walls and ceilings here is some advice, and a few tips to help you get the job
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 two 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.
For ceilings, the use of jobspecific ceiling whites are highly recommended. They are ultra flat in sheen and mask surface imperfections.
Generally, solvent-based enamel paint is the toughest, giving the hard-wearing surface you want for areas needing constant cleaning, such as doors, windows and furniture.
Walls frequently subjected to a damp atmosphere – kitchens, bathrooms and laundries – may merit the extra time it takes to apply enamel.
However, with the advances in technology, water-based enamels are now replacing the traditional oil-based enamels.
For flat areas such as ceilings, walls and doors, multiply their length by their height, subtracting 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 per cent to this quantity for rough or porous surfaces. 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 oilbased paints, use a 6mm mohair nap sleeve or a 5mm foam sleeve.
Make sure you select a roller frame with a threaded handle that allows you to fit an extension to take the backache out of reaching ceilings and high walls.
When it comes to choosing ecofriendly paint, the first and most important thing to look for is the amount of volatile organic compounds contained in the product.
The lower VOCs (solvents that get released into the air as paint dries, causing nasty odours that can contribute to diminished air quality) the better.
If there’s no flaking or peeling, wash down well with sugar soap to remove dirt, grease and smoke stains.
If there’s any mould use sugar soap, then treat with an antimould 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.
Use an electric hot air stripping gun (except around window frames or you’ll break the glass), or chemical paint stripper to soften the old paint, making it easy to remove with a blade. Then sand, wash down with sugar soap and treat as a new surface.
