<\/span> EXTERIOR CARE<\/span>

A freshly painted house can look tired within months: grey dust on the walls, dark streaks under every window, mud splashed along the base. Most of it is preventable with the right paint and a few simple details.<\/p>

Short answer:<\/strong> Exterior walls get dirty because dust from roads and construction sticks to the paint, rainwater carries dirt down from sills, parapets and sunshades in streaks, and rain splashes mud onto the lower wall. To stop dust and dirt sticking to exterior walls, use a smooth, dirt-resistant exterior emulsion with good sheen, add drip grooves under sills and sunshades, protect the base with a darker plinth band and a gravel or grass strip instead of bare soil, and choose mid-tone colours on the walls that face the road. A gentle wash once or twice a year keeps the finish looking new.<\/p><\/div>\n
