Are you looking for the best render cleaning methods? This popular material is great for building exteriors, but it can start to look a little worse for wear over time as the surface accumulates grime and stains. While traditional high-pressure jet washing can be damaging on more delicate surfaces, there are other methods like softwashing for keeping exteriors looking sparkling.

Here’s everything you need to know about render cleaning using softwashing techniques.

What makes render look dirty?

Render is a great choice for finishing property exteriors, thanks to its sleek and versatile appearance. While it may start out modern and fresh, render’s initial pristine appearance can begin to look less than its best when dirt, fumes, dust, grime and other marks affect everything from the smooth finish to the sharpness of the colour.

Biological matter, such as moss, algae and lichen, can also start growing on places like roofs and render, leaving green or black spots across the surface. These growths thrive on porous surfaces like render, especially where there’s moisture present. If left untreated, moss and algae can cause other issues like cracks and degradation of the render.

Does high-pressure jet washing damage render?

While high-pressure jet washing is great for cleaning many exterior surfaces, it may not be the best option for your render. Professional jet washing companies will always assess the surface to work out the best methods to use. If the render is old or delicate, it may be damaged by intense forces, stripping away the top layer or leaving chips and cracks. It may also force more water into the render, causing interior damp issues.

What’s the best exterior cleaning method for render?

Softwashing is the preferred method for cleaning render surfaces like K-rend and monocouche. Softwashing methods use low-pressure sprays which are kinder to surfaces. It also means the water won’t get deep into any small cracks around the building exterior.

Softwashing is still highly effective, thanks to a special cleaning solution used alongside it. This contains biocides which kill and remove algae, moss and lichen at root level. It stops spores returning for a longer-lasting clean.

What else is softwashing used for?

As well as cleaning render, softwashing can be used for various exterior surfaces that need a more delicate approach than blasting away grime with high-pressure washing. Roofing is a good example, using softwashing to remove all kinds of grime and algae without getting water into small cracks that would seep into the internal structure. It also means delicate roof tiles can be cleaned without causing damage. Softwashing is a great option if areas of your patio, driveway, decking, walls or paths need a gentler approach to exterior cleaning.
