Why You Cannot Pressure Wash Render

High-pressure washing damages render. Both monocouche and traditional sand-and-cement render are porous but brittle. High pressure drives water behind the surface, causing cracking, blistering, and detachment. Once render is damaged, repair costs run into thousands. Soft washing uses low pressure combined with a specialist biocide solution — the chemistry does the work, not the pressure.

Pressure Wash vs Soft Wash: Why It Matters

What Drives the Price Up or Down

• Coverage area: Front elevation only costs half what a full-wrap property costs.
• Severity of staining: Fresh algae clears faster than years of established black lichen.
• Render type: Monocouche render needs especially careful chemistry selection to avoid discolouration.

How Long Does Render Cleaning Last?

A professional soft wash with biocide typically keeps render clean for 12 to 24 months. North-facing walls that stay damp and shaded see faster regrowth — closer to 12 months. South-facing, open elevations can stay clean for two years or more.

FAQ: Will Render Cleaning Change the Colour?

Soft washing removes biological growth but does not affect the render colour itself. Your render will look the colour it was before the algae and moss covered it — which is often brighter than homeowners remember, because it's been covered in green for years.

FAQ: Why can't you just pressure wash render?

Render is porous but brittle. High pressure forces water behind the surface causing cracking and detachment. Even a single high-pressure clean can cause render to blister or come away in patches within months. The repair cost runs to thousands. Soft wash uses chemistry, not pressure.

FAQ: Will render cleaning damage my K-Rend or monocouche finish?

Not when done correctly. We adjust biocide concentration for K-Rend and monocouche — lower strength than for pebbledash or older painted render. If unsure of the render type we test a small area first and confirm the result before treating the whole wall.
