Why Render Needs a Specialist, Low-Pressure Clean

Render, whether traditional sand and cement, silicone, acrylic or monocouche, is one of the most common exterior finishes on New Forest homes. It's also one of the quickest to discolour. North-facing walls, shaded gardens and damp coastal air create the perfect conditions for green algae and black staining.

The problem is that many people reach for a jet wash. High-pressure washing can crack, pit or discolour render, strip coloured finishes and force water into the wall. Purefection uses low-pressure methods and specialist solutions instead, which kill and remove the growth at its root rather than blasting the surface.

Every property is assessed individually before the right treatment is chosen. That matters because different render systems react differently, and the wrong approach can cause damage that is far more expensive to put right than the clean itself.

What Happens When Render Is Left, or Cleaned Wrongly

Growth Spreads

Algae and organic growth hold moisture against the wall and spread steadily, making staining harder to remove the longer it's left.

Pressure Damage

High-pressure washing can crack, pit or discolour render, damage that often means costly repairs or re-rendering.

Reduced Property Value

Stained render makes a home look neglected and can put off buyers or tenants.

Common mistakes we see

  • Jet washing render, which damages the surface and voids some manufacturer guarantees.
  • Using household bleach, which can discolour coloured renders and harm plants.
  • Painting over algae instead of treating it, so it comes straight back through.
  • Cleaning one wall and leaving the rest, creating an obvious mismatch.

Render Types, Treatments and How Long Results Last

Silicone and Acrylic Render

Modern thin-coat renders are popular for their colour and finish but are prone to algae. Low-pressure softwashing with specialist solutions cleans them without damaging the coloured surface.

Monocouche Render

Through-coloured monocouche render can mark easily with pressure. A gentle, chemical-led approach is used to restore the original colour.

Traditional Sand and Cement Render

Painted or unpainted traditional render is cleaned with low-pressure methods that lift staining without eroding the surface.

Pebbledash and Textured Finishes

Textured renders trap dirt and growth in every crevice. Softwashing reaches into the texture without dislodging stones or aggregate.

Residential vs Commercial

From single walls on a family home to full elevations on commercial buildings, high-level render is cleaned using water-fed poles or cherry picker access up to approximately 15 metres.

How Long Does Clean Render Last?

It depends on shade, moisture, vegetation and local climate. A professional softwash can often keep render looking fresh for several years before regrowth returns, with treatments applied to help slow it. Kieron can give property-specific guidance at quotation stage.
