Should You Pressure Wash Before Getting Exterior Painted?
Over time, dirt, grime, and biological contaminants accumulate, dulling its appearance. Many assume a fresh coat of paint is the answer. But before you reach for the paintbrush, consider this: Should you pressure wash before getting exterior painting done?
Pressure Wash Before Exterior Painting.
After a day off-roading, your Range Rover is filthy. Time for a bodywork respray? Ridiculous, why would you want to respray a car when it’s just dirty – but this is usually the default position to solving the problem of a dirty building façade.
Little consideration is given to enormous strides that have been made in building façade technologies, not only in improving building thermal efficiency but also in lowering maintenance costs. Let’s take rendered building surfaces and systems as an example.
Many through-colour, monocouche-type render and EWI systems (such as KREND, Wetherby, and Sto) have extensive performance guarantees, as much as 25 years in some cases. Repainting should only ever be considered as a last, not first, resort.
Most contamination to building surfaces is environmental—everyday grease, grime, and bacterial staining (biofilm).
In nature, biofilms are almost always a broad spectrum of species: bacteria, fungi, algae, moss, lichens, yeasts, protozoa, and other microorganisms.
Painting, even with the best “prior to paint” cleaning discipline, will not cure the problem—only its visible symptoms. Expect a return of staining in a very short time.
Why Cleaning is the Smarter Choice
Why not think of cleaning first? On most low-rise buildings and homes, it’s no more complex than a window cleaning programme—it can even be completed from the kerb side– so it’s also very low cost.
Conversely, operator risk and health requirements dictate that even on low-rise façades, some form of expensive access equipment is utilised to ensure painters are safe – making a painting programme very expensive.
- Only Eco-friendly products
- Outstanding results
- Long-term Warranties
- Guaranteed Satisfaction
Enormous savings can be made in replacing a planned painting maintenance cycle with a low-cost “clean and sanitize” cycle.
What to use
A good exterior cleaning contractor will want to inspect your building before recommending the right approach– most staining will be biofilm plus some general grease & grime.
A cleaner which is surfactant (soapy like Fairy washing-up liquid) will grab the grease and grime, combined with a high-purity biocide.
A biocide is attracted to living organisms like a magnet is attracted to metals.
It kills biofilms by cationic action in piercing cell walls.
Using a high-purity biocide will guarantee that your cleaning product will not interact with any component that makes up your building façade.
DDAC, for example, is non-oxidising—its chemical composition means that it cannot affect anything that is not a living organism making it safe on sealants, coatings, thatch, etc and it will not oxidise on lead flashings, aluminium or turn uPVC yellow.

So safe on all building surfaces. A big bonus in that it’s also biodegradable. Other non-bacterial staining will demand its own treatment unique to what causes it.
For example, iron oxides from soil splashes and other “metallic” staining caused through TV aerial fixings—a competent contractor will advise as to the solution.
Make the Right Choice—Clean First!
Repainting a building may seem like the logical step, but if contamination is the root issue, a new coat of paint will not fix it.
Instead, take the professional approach: clean first, and preserve your property’s appearance without unnecessary painting costs.
