Prince Rock (PL4) render softwash
Prince Rock, Devon - PL4
This page is about one job in one place: cleaning brick and painted render walls in Prince Rock, Devon. Softwash means chemistry and dwell time doing the work rather than pressure.
What Prince Rock walls are usually finished in
- Bead edges and stop ends on a rendered elevation are the details worth protecting from driven water.
- A rendered wall under a failed drip detail restains within a season however well it was cleaned.
- Efflorescence on brick is salt, not growth, and it is left to weather rather than treated.
- Painted brick is treated as paint, not as brick, and the test patch decides the strength.
- That gets pointed out before work starts rather than discovered halfway through.
- A test patch low down and out of sight is how failing paint is found deliberately.
Low pressure, longer dwell
- 1.Any surface that will be walked on afterwards is left rinsed rather than left with residue.
- 2.Sheltered corners and inside angles hold growth longest and get worked before the open faces.
- 3.Where a wall has been previously jet washed, the damaged band is treated at a reduced strength.
- 4.Gutter faces and fascia boards are wiped as part of the same pass, since they sit in the same spray path.
- 5.Render beads and stop ends are inspected as work reaches them, because a lifted bead traps water behind the finish.
- 6.Where a porch roof sits mid-elevation, it is sheeted and its own tiles cleared before the wall above is touched.
- 7.Cills, frames and glass are wiped down as the masking comes off, so nothing dries as a film on the joinery.
- 8.Applications are kept off hot surfaces in direct sun, because a mix that flashes off has no dwell time at all.
- 9.Where a wall runs straight down to a lawn, a run of sheeting is pegged along the base instead of relying on dilution alone.
- 10.Work stops if a wall turns out to be wetter inside than out, because cleaning is not the answer to that.
Small things that make the visit smoother
- Let us know if anyone in the house works nights and needs quiet at a particular time.
- Say if the property has a flat roof section that we would be working above.
- Point out any window that does not seal properly, so it gets sheeted rather than sprayed near.
- Say where the outside tap is, and whether it runs at any pressure.
- Point out where the render was patched, since patches clean differently from the original.
- Tell us about any planting you particularly care about at the base of the wall.
- Bring in washing, cushions and anything fabric that lives against the wall.
- Tell us if there is a septic tank and where its outlet sits.

What is actually growing on the wall
- Old sealant around window heads cracks and lets a thin trickle run down the face below.
- A cracked cill throws water back at the wall instead of clear of it.
- Shading from a neighbouring building can matter more than the aspect of the wall itself.
- Growth that appears in a neat rectangle usually marks something that was leaning against the wall.
- Rain running off an unsealed timber fascia carries tannin down the wall as a brown stripe, not growth at all.
- A wall that faces a large expanse of glass on another building gets less sun than its aspect suggests.
- Salt-laden air roughens exposed surfaces slightly, and rougher surfaces hold more moisture.
- Salt spray does not itself grow, but it roughens and holds damp, which is the same outcome.
- A wall that never takes direct sun stays damp for hours after everything else has dried, and that extra time is the whole story.
Assessing a PL4 elevation
- 01Weep holes are counted and checked for blockage while the wall is being read.
- 02A wall that feels chalky under the hand is telling you the coating has aged, not that it is dirty.
- 03The age of the finish is estimated before a strength of mix is chosen.
- 04Whether the property is exposed or sheltered is judged on the day, not from a map.
- 05Efflorescence is distinguished from lichen before anything is applied, since one is salt and one is alive.
- 06The direction the growth thickens in points at the source of the moisture.
- 07Any staining that continues below ground level is a drainage question, not a cleaning one.
- 08Colour matters: green suggests algae, black suggests fungal spotting, grey-white crust suggests lichen.

Before you get in touch
- Can you do it while I am at work?
- Yes, as long as gates are unlocked and we can reach the elevations.
- Do you need my electricity?
- No. Kit runs off the van.
- Can you clean render on an insulated system?
- Yes, with extra care around bead edges where water should not be driven in.
- When does a treated wall show its final appearance?
- Some change can be visible after treatment, while remaining dead growth may continue to weather away over the following days.
- Do you have a minimum size of job?
- A single gable or a porch is still worth doing properly.
- Will the wall need doing again next year?
- Not usually. How long it holds depends on shade, run-off and airflow rather than on the treatment.
- Is it safe around pets?
- Keep them indoors during application and for a couple of hours after, and there is nothing to worry about.
- Do you need a parking space?
- Somewhere within hose reach of the elevation is enough.
Tell us about the access
Narrow passages, soft ground and shared drives are all normal. We just need to know.
The short version
If a wall is greening in one strip, the answer is usually plumbing rather than cleaning. Doing the roof, gutters and walls in the right order is most of the value. Shade, run-off and airflow decide how long a clean lasts. The treatment decides whether it worked at all. Monday to Saturday, 8am to 7pm.
