Condition and preparation
Check render, old paint, rain streaks and damp at junctions. Remove unstable material and allow washed masonry to dry.
Materials and application
Match the exterior masonry system to the substrate and exposure. Plan each face around shade, rain and the product's recoat window. Trial the lowest effective cleaning intensity on a small area and protect openings from wash water.
What to put in the quotation
For the quotation, include surface type, staining, drainage and fragile nearby fittings. Check whether washing, access and making good damaged render are included.
Frequently asked questions
Must every exterior wall be pressure-washed?
Fragile render and openings may need a gentler method. Agree protection, water collection and drying before paintwork.
How should I look after the finish?
Check exposed edges after heavy rain; recurrent staining near a joint is a reason to investigate water entry before touching up.
