There’s no reason why you should neglect outside walls. There’s nothing better than al fresco summer dinners or days spent by the pool, so put a little time and care into your exterior walls and keep them looking great whatever the weather. If you don’t have an outdoor area, you can use your creativity to redesign your entrance way or front door.
If timber is bare and has been weathered by rain or wind, it may need to be sanded down to avoid peeling and flaking.Bare metal
Different metals have different properties, all of which react to paint differently. Bear in mind the type of metal you’re painting to ensure you get the best results. Metals such as aluminium, copper, brass or stainless steel cannot be painted. Some metals are also likely to rust – think wrought iron or steel – so ensure that their surfaces are cleaned and rust free before painting. For metals that are already rusty, sand them down or use a wire brush to remove the rust then apply an all-metal primer.Stripping and sanding
To strip back paint, you’ll get the best results by using a heat gun or a chemical stripper. If you’re only working on a small area, try a wirebrush or dry scraper. For sanding, you may want to get a mechanical sander to avoid hours spent labouring with sandpaper.Mould
Use a solution of one part household bleach solution mixed with three parts water to remove surface mould with a scouring pad. Always wear gloves and goggles, and leave the solution on the affected area for 15 minutes before washing with clean water. Repeat to fully remove the mould as it can take several attempts.Flaking and peeling
North- and west-facing walls are most prone to flaking and peeling as these areas receive the most heat from sunlight. Flaking and peeling is usually caused on wooden surfaces by moisture being trapped beneath the paint and is more common with dark colours and those that have been applied over old paint. Try to root out and eliminate the source of the moisture – this is usually via cracks under windows and doors or through condensation in the wallsBare masonry
For painting these inevitably rougher surfaces, it’s important to remove all loose material with a stiff brush. If the surface remains powdery or porous, priming is recommended to improve adhesion and durability of the paintwork.
