Jetblack Painting pressure washes driveways, paths, decks, fences, roofs and house exteriors across Melbourne, both as a standalone job and as the first stage of an exterior repaint. High pressure is a useful tool and an easy one to misuse, so the work is about matching the pressure and method to what is being cleaned.
Jetblack Painting is a 5-star rated Melbourne business with 18+ years of experience, $10 million public liability insurance, and a 5-year workmanship guarantee on every project.
The same pressure that cleans a concrete driveway will gouge timber, blast the mortar out of old brickwork, strip the face off soft render or drive water in behind weatherboards and cladding. Surfaces differ a lot, so the pressure, the distance and the nozzle are chosen for what is in front of the wand.
Older paint can also lift and peel under a strong jet. That is sometimes what is wanted ahead of repainting, but it is not what you want on a surface that is meant to stay as it is.
Blasting moss and mould off with water alone often leaves roots and spores behind, and the surface greens up again quickly. Treating the growth with an appropriate cleaner and letting it work, then rinsing, usually lasts longer than force alone.
Shade, poor drainage and constantly damp ground are why the same spots go green again. Washing deals with the symptom, so it is worth thinking about the cause too, such as an overflowing gutter or garden beds banked against a wall.
Paint does not stick to dirt, chalking or mould, so washing is the first step of most exterior repaints. It removes the dust and surface chalk that stops a new coat bonding, and shows up loose or failed paint that needs scraping.
Surfaces then need to dry before anything is applied. Painting over a wall that is still damp traps water behind the new film, which is a common reason for early blistering. We judge dryness by the surface and the weather, not by a fixed wait.
Wash water carries dirt, paint flakes, oil and cleaning products. It should not be allowed to run into the stormwater drain, which discharges untreated to local waterways. It is a fair question to ask any contractor how they manage it.
Yes, if the pressure is wrong for the surface. It can gouge timber, wash out mortar, strip soft render or force water behind cladding. That is why the pressure and nozzle are chosen for each surface instead of using one setting for everything.
Both. It is a standalone service for driveways, paths, patios, decks, fences and roofs, and it is also the first stage of an exterior repaint.
It can lift paint that has already failed, which is useful before repainting. It will not reliably strip paint that is still sound, and we would not use more pressure to try on a surface that could be damaged.
Usually because the cause is still there: shade, damp ground or water running onto the surface. Treating the growth as well as washing it off lasts longer than blasting alone, and fixing the moisture source helps most.
It depends on the surface, the weather and how much water it took on, so there is no single answer. Painting over a damp wall can trap moisture and cause blistering, so we judge it from the surface itself and the forecast.
Yes. Moss, lichen and grime can be washed off both tile and metal roofs, whether or not the roof is being repainted afterwards. If washing shows up cracked or slipped tiles, we flag them, because those are repairs and not cleaning.
