With the launch of Dulux Diamond Exterior Satin, a breakthrough paint that resists early showers, Dulux Paints offers these tips to ensure a successful outdoor painting project every time.
Prepare for the best: With harsh winters taking a toll on Canadian homes, leaving painted surfaces peeling and blistering, surface preparation is the most important part of the exterior painting. For the longest-lasting results, clean the area thoroughly with a phosphate-free cleaning solution, and then rinse with a garden hose or pressure washer. Scrub with a brush to remove any dirt and grime, and use a scraper, putty knife or wire brush to loosen debris from deteriorating surfaces. Fill holes and cracks with acrylic‑based caulking and smooth surfaces with 120 grit sandpaper.
Take it stroke by stroke: Always make a plan or timetable for your job. It’s best to work from the top down, starting with fascia boards, gutters, and eavestroughs, and then moving on to walls and downspouts, leaving the trim for last. If painting boards or siding, focus on one or two boards at a time, going from one end to the other – rather than working in sections – to avoid overlapping. Begin painting on the side of your house that remains in the shade the longest since painting in direct sunlight can cause blisters and lap marks.
Choose tools wisely: When it comes to selecting a brush, a four-inch straight-edged brush is best for broad surfaces like siding, while a two-inch brush is suggested for trim. Rollers work well on porous surfaces such as masonry or stucco and are also useful for covering flat surfaces. When painting large areas, try using a spray gun instead for a uniform, professional finish. Products such as the Graco TrueCoat Pro sprayer, available at Dulux Paints stores nationally, can complete a paint project in half the time of a brush or roller.
Know that less is more: While priming the surface to be painted is a good idea when it comes to painting, never overdo it. There’s a limit to the number of coats a surface can support. As paint ages and thickens over time, it loses its flexibility and ability to expand and contract, causing premature cracking or flaking. For long-lasting results, apply a maximum of two even coats of paint to achieve the desired colour appearance and surface protection. Never paint wood when it is wet as the new paint will rapidly blister and flake off.
Open your door to colour: The front door is one of the most important features of any home, so you can instantly brighten up your property by painting it a more vibrant colour. A freshly-painted front door will also help block the sun’s damaging ultraviolet rays. When painting the trim, wedge the door open as you work. Begin with the jamb and stop, starting at the top on the inside corner and working your way down. While the jambs are still wet, paint the casings, being sure to mask the outside edges. Paint the threshold only after the jambs and casings have dried.
