While interior and exterior paints have many of the same properties, they also have differences which make them more suitable for various applications.
Interior paints need to be hard-wearing and washable, exterior paints must withstand damaging UV rays. HL chatted to Prominent Paints’ Senior Technical Service Consultant, Pieter Greef about how to choose the right paint for interior and exterior projects.
How do we choose the right paint for interior and exterior jobs?
A quality interior paint will also have a low VOC level which reduces odour when painting indoors. Exterior paints must be flexible to bridge cracks, be fungal resistant and have low dirt retention. For best results and good longevity, it’s important to choose the correct paint for the intended purpose and application. Exterior paint used indoors isn’t tougher or harder wearing, and on the other hand, interior paint used outdoors may fade and peel. The chemical composite of paints has come a long way since the early days of paint manufacturing. Products are more specialised for certain substrates, although a roof paint works well on a roof, the same paint does not cure properly and won’t last if used internally. An exterior wall paint does not have the same scrub resistance as an interior wall paint, and an interior wall paint is not flexible enough, nor does it have enough UV stability to be used outside.
Why is quality important?
Choosing a superior quality paint not only makes the job of painting a room easier, it also ensures a long-lasting result. Prominent Paints Premium is a high performance pure-acrylic range with a seven-year life expectancy. All paints for interior and exterior applications in the Premium range are fully-washable, steam, water and stain resistant, a product enjoyed by professionals and DIY’ers alike.
How do we choose the right finishes?
With the number of finishes available today, the choice can be as difficult as choosing the type of paint and colour for a room. Sheen refers to how shiny paint looks when dry. Matt paints provide a smooth, yet stylish finish, hiding blemishes on the wall surface. Both eggshell and Non Drip enamel are easy to clean and have good stain resistance, while high-gloss paint has a very shiny finish. A good rule of thumb is to first consider the area being painted. High traffic areas need a durable, scrubbable paint that resists stains and marring. Semi-gloss paints are suitable for high moisture areas like kitchens and bathrooms or children’s playrooms where additional cleaning will likely be required.
Do you have any fast tips for us?
- Always mix the paint thoroughly with a flat paddle before pouring into the paint tray.
- If working with different paint colours, slip the paint tray into a plastic bag and pour the paint onto the bag. Simply remove the bag and pour the paint into the clean tray when a colour change is required.
- Never dilute paint to achieve more coverage. This only compromises quality and lowers adhesion strength.
- Before painting, always wash the roller in clean water to remove traces of fluff. Spin dry the roller to remove excess water; then hang up to dry thoroughly.
- When applying paint, cut around cornices, ceilings, skirtings and corners first, then fill in with a roller.
- Adhere to drying times indicated on the paint container before applying a subsequent coat. This will ensure proper coverage and a quality, professional finish.
