- Exterior walls. Before painting, to remove dirt and loose chalky paint.
- Concrete roof tiles. Moss, lichen and dirt.
- Paving and driveways. Brick paving, concrete and pool surrounds.
- Boundary walls. Precast and plastered walls.
- Bin areas and parking bays. Commercial and complex upkeep.
Surface-Specific Precautions
- Soft plaster and old paint. Too much pressure can damage plaster. Lower pressure or a wider nozzle is used.
- Roof tiles. Cracked tiles must be replaced, and water should not be driven up under tile overlaps.
- Asbestos-cement. Old fibre-cement roofs and walls should not be pressure cleaned. Ask about asbestos handling.
- Timber. High pressure raises and splinters the grain. Decks are cleaned at low pressure.
- Windows and seals. Water is kept off window seals, vents and electrical fittings.
- Run-off. Dirty water and moss should be kept out of gardens and stormwater drains where possible.
Cleaning Before Painting
- Remove loose paint and treat moss or mould where needed.
- Clean from top to bottom at a pressure that suits the surface.
- Rinse away residue and any cleaning products.
- Let the surface dry fully before primer or paint goes on.

- Water and electricity on site.
- Treatments such as moss killer or sealing after cleaning.
Pretoria Conditions to Plan For
Pretoria's summer storms leave mud splash on lower walls and feed moss on shaded roofs and paving. Water restrictions can apply in Tshwane during shortages, so confirm with the contractor that their cleaning method follows any restrictions in force. Surfaces dry quickly in the dry winter months, which suits cleaning before painting.

Get the Best QuoteHigh Pressure Cleaning Pretoria FAQs
Is high pressure cleaning needed before painting?
Usually yes on exterior walls and roofs. Paint does not bond well to dirt, moss or loose chalk.
Can pressure cleaning damage my walls?
It can if the pressure is too high for soft plaster or old paint. Ask how the contractor sets pressure for each surface.
How long must walls dry before painting?
Usually at least a day in dry weather, longer in cold or humid conditions. The paint product's instructions apply.
Can paving be sealed after cleaning?
Yes. Many contractors offer sealing as a separate item. Ask for it on the quotation if you want it.
