If you're planning to paint your home’s exterior, experts are warning that pollen can affect the quality of your paint job. 

Although invisible to the naked eye, pollen can lead to a patchy, flaky finish when painting a house, according to DIY experts at both Ronseal and Toolstation.

"High pollen levels can stick to wet paint, causing an imperfect finish and potential flaking. Pollen can also stain the paint, especially if you’re using bright or light colours," explains Cara Yates, senior category manager at Toolstation.

Keep an eye on pollen counts

Cara Yates recommends checking the pollen forecast before starting your exterior painting project to reduce any chance of potential problems.

"Pollen levels peak from March to September, which is also the ideal time for exterior painting," she explains. 

"Since exterior paint takes 6-24 hours to dry, try to schedule your painting when pollen counts are low," she adds.

Choose mild, windless days to paint

Yates adds that painting during windy, warm days can have a significant effect on the quality of your home's paint job too.

She states: “High winds and warm temperatures play a key part in dispersing pollen from the ground which could then end up interfering with any wet paint on the exterior walls of your home. 

“Choosing a cooler day with lower wind forecasts will help prevent a patchy appearance whilst ensuring a quality long-lasting finish.”

Clean walls thoroughly before painting

Jimmy Englezos, Senior Brand Manager from Ronseal, emphasises the importance of preparing your walls before painting

"Regardless of how good your paint is, it can only adhere properly to a clean surface," he says. "Debris, dirt, or pollen on the wall will cause the paint to flake and look patchy."

Englezos advises cleaning exterior walls with warm, soapy water or sugar soap. "Make sure to remove any loose or flaky paint before applying a new coat. Once the surface is clean, allow it to dry completely before painting."

Avoid high pollen periods when possible, he adds, as a little planning can save time and effort, giving you the best possible results for your investment.
