  • Q.
  • Is it better to paint or wallpaper my interior walls?

    There is no right or wrong choice, you can mix and match; both Paint and Paper can be used in contrast when decorating a room. Wallpaper is great because it is more washable and hides imperfections. At Mt Smart Paint and Paper we offer friendly-expert advice and tips that can help you achieve great value for money. 



  • Q.
  • How wide is a roll of wallpaper?

    The average size is 52.5 cm.  The average roll is 10 metres so you’ll get about 4 drops from one roll.


  • Q.
  • How many rolls of wallpaper will I need for a room?

    Measure the length and height of each wall you wish to cover in wallpaper.

    You can round the length measurement up to the nearest metre to make it easier to calculate.

    Include your windows and doors in these measurements. The average wall height is 2.4 metres.

    Multiply the length and width of each wall to get the area in square feet.

    Add up the area of each wall to get your total area.


  • Q.
  • How much Roof Paint should I purchase?

    You can work it out using the perimeter of the house x the pitch of the roof.

    Call Mt Smart Paper and Paint for advice.


  • Q.
  • What do I need to do to prepare my Roof for Painting?

    Check your roof before getting requirements

    Mould and rust must be killed before paint application.

    Mt Smart have the best products available and will show you how to use them. All surface rust will be killed.

  • Q.
  • Can you paint in direct sunlight with acrylic?

    Generally cloudy or overcast days are the best for painting.

    Don’t paint in direct sunlight or in extremely hot weather.

    If time is a factor paint the shady side of the building or wait until the temperature drops.

    A good idea is to start ahead of the sun and work your way around the building keeping ahead of the sun

  • Q.
  • How do you know what type of paint is on the surface?

    To find out if you have lead, acrylic or enamel, rub with methylated spirits.

    If the colour comes off on the rag, it’s water-based.

  • Q.
  • How do you know if you have lead-based paint?

    If your house was built before 1980, assume it has some lead-based paint. 

    You need a Lead Testing Kit, which Mt Smart Paper and Paint can order in for you.


    Lead-based paint is only a danger to health if it has deteriorated, for example, it has started to flake.

    If it’s in good condition, repainting it is a good option rather than trying to remove it.

    Removing it is likely to increase the risk of exposure from dust and flakes.


    How to remove Lead-based paint.

    If you find  lead-based paint the best method to use to remove it is  wet sanding.

    Mist painted surfaces with a spray bottle and remove paint using sharp scrapers or wet and dry sandpaper.

    This keeps the dust to a minimum.

    Machine sanding is not recommended because of the amount of dust generated.


  • Q.
  • Does all the old paint have to come off when repainting?

    This depends on the standard you want.

    Walls need to be scraped, edges sanded and spot primed,

    then undercoated,  followed by the topcoat to complete  the finish.

    When painting weatherboards it is most important that you have the right scraper.
