K Rend is a very popular product amongst new builds. Although it looks great when it is new, within a few years algae will start to grow on the surfaces. The algae growth will leave the render with green marks, black mould and sometimes red streaks. You may be wondering, can you jet wash K Rend?
Before you pick up the pressure washer, there are a few important things you need to consider.
Pressure Washing will not kill the algae growth. This means, even if the render looks slightly better after Pressure Wash, the algae will soon grow back. It needs to be killed. This should be carried out by a soft wash chemical treatment.
High-pressure cleaning can damage render. When high pressures are used to clean K Rend the top layer of the surface is removed from the property. As K Rend is only a few millimetres thick, you will soon run out of Render.
Jet Washing Render can lead to a stripy finish which can look odd. With every pass of the pressure washer a stripe will be formed on the surface. When these stripes show, it is tempting to Pressure Wash harder to remove this striping. However, this will just catch more of the surface away. When the algae starts to grow back, it will grow back in stripes, which can leave the building looking a little weird.
What is the best way to clean K Rend?
Pressure washing rendered walls is not the best approach to render cleaning. If you have been searching for how to clean render, there are a few options available. Softwash render cleaning is the best way of cleaning your K Rend, although a light steam clean is needed to remove surface deposits.
When it comes to cleaning K Rend, it is best to employ a professional Render cleaning company. Using the correct chemicals for soft washing, along with a low-pressure steam clean, the best results can be achieved, without any damage to your property. By carrying out these methods of cleaning your render will stay cleaner for longer as the biofilm has been killed and will not return for several years.
How much does it cost?
Render cleaning prices will vary according according to location, level of algae growth, access etc. When thinking about how to clean monocouche render or K Rend, it is important to choose a long established render cleaning company. Ask to see photos of their work and testimonials. Remember, cheaper is rarely better.
