Painting pointers


Paint is the finishing touch for a ital looking eterior for either new builds or refurbishments, but as Tony Pearson-Young from AkzoNobel says, there is some essential practical advice to bear in mind


A


fresh coat of paint can help rejuvenate and transform a tired looking house into a stunning


property that looks just like new – and if it’s a newly built property, adding a lick of paint can add a touch of character, too. However, there are some tricks of the trade that you should know before tackling an exterior painting project.


SEASON VS TEMPERATURE


The time to complete exterior painting projects is often associated with seasons, but it is less about seasons and more about temperatures, as temperature – whether too hot or too cold – can greatly impact the quality and longevity of the paint and its application. Painting in extremely hot weather (over 30°C) can cause paint to dry too quickly, leading to a poor finish and potential adhesion problems. The paint will likely crack and blister which can result in peeling and lead to visible brush or roller marks, further affecting the professional finish. Painting in temperatures below 10°C is likewise not advisable, as it can slow down the drying and curing process causing the paint to become tacky and wet to the touch. Although daytime temperatures might suffice its important to check what the temperature will fall to overnight, as if it’s expected to drop below 10°C, it could negatively impact the finish. t these lower temperatures especially towards the end of autumn and early spring, there is a lot of moisture and condensation on surfaces, which will affect adhesion and the overall quality of the finish.


PREP IS KEY


Exterior painting projects require some additional preparation compared to interior proects to ensure a perfect finish is achieved. All walls and surfaces require cleaning before work is undertaken to remove dirt, grime or loose paint, and to guarantee that all surfaces are smooth. What’s more, mould and algae can sometimes be found, especially on a northern elevation, so a fungicidal wash

must be used to banish any existing mould as well as prevent the future growth of fungi, mould and algae. Due to the way that temperature can impact eterior proects efficiency should be prioritised. Tools such as jet washers, power-fed rollers, and spray machines all make the task of painting a lot quicker and easier to help avoid any


bad weather. In addition, using easy to apply and fast drying paint also saves time on a project.


KEEP SURFACES LOOKING FRESH When selecting paints, it’s vital to choose products that hae been specifically designed for exterior use, as they have been through rigorous testing
