Can you pressure wash a rendered house?

Pressure washing is an effective way of cleaning all sorts of outdoor surfaces, from driveways and patios to decking and brickwork. But what about rendered houses? It’s a common question that many homeowners have: Can you pressure wash a rendered house? The answer, as with most things in life, it depends.

Render is a durable material that can withstand harsh weather conditions and wear and tear. But it is also porous, meaning it can absorb water and potentially weaken over time. However, there are a few things you need to bear in mind before you start blasting away at your render. In this article, we will explore the pros and cons of pressure washing a rendered house and help you decide if it’s the right choice for you.

First off, it’s important to note that the type of render on your house will play a big role in whether or not pressure washing is an option. If you have a traditional cement render, pressure washing is usually fine as long as you use a low pressure setting. However, if you have a delicate, acrylic or silicone render, pressure washing could potentially damage the surface and is not recommended.


What is a rendered house?

A rendered house is a building where the exterior walls have been coated with a layer of cement, plaster, or other material. This can be done for aesthetic or functional purposes. Pressure washing a rendered house is totally dependable on the type of render you have, but it is important to check with the manufacturer of the render to see if there are any special instructions.

Can you pressure wash a rendered house?

It is not recommended to pressure wash a rendered house.

It is not recommended to pressure wash a rendered house. The high-pressure water can damage the render, causing it to crack or flake off. In addition, pressure washing can force water into cracks and crevices in the render, which can lead to damp problems. If you do decide to pressure wash your rendered house, be sure to use a low pressure setting and hold the nozzle at least 30cm away from the surface.


Pros and cons of pressure washing a rendered house:

Pressure washing can be a quick and effective way to remove dirt and grime buildup on your render. It can also reach hard-to-reach areas, such as high up on walls or in corners. The main benefit of pressure washing a rendered house is that you will be able to remove stains that cannot be removed by brushing or rinsing. This will lead to less maintenance work in the future.

One of the disadvantages is that pressure washing can damage the render, which is an expensive material. However, there are a few drawbacks. We have already mentioned that pressure washing can cause render damage. The other problem with pressure washing a rendered house is that many renders are designed to have an attractive matt finish. Pressure washing can remove this finish, making the house look shiny and new – but in a way that many people find unattractive.

Another issue is that certain paints and coatings are sensitive to water. If the washer has a powerful water flow, the paint could peel away from the surface it is attached to. Pressure washers that emit low pressure are less likely to have this effect, but should still be used with caution.

That being said, pressure washing can be a great option for removing stubborn dirt and grime from rendered surfaces. It’s also a quick and cost-effective solution compared to traditional hand washing methods.

Ultimately, the decision of whether or not to pressure wash your rendered house should come down to the type of render and your personal preference.
