Keeping render clean

​​​​​​​Have you decided on a render finish? Render offers a clean, modern, and attractive finish to any project which, if properly maintained will last for many years. Weber one-coat and multi-coat render systems offer a wide range of finishes including dry dash, ashlar and scraped finish.

Dry dash (pebble dash) is a particularly durable finish, and as such is often used in areas which are more exposed to the elements. Different finishes will require different levels of maintenance as they weather depending on the location, altitude and aspect of the build.

A render finish is a relatively low maintenance option. Unfortunately, low-maintenance doesn’t mean no maintenance. Here are some handy tips on how to clean rendered walls to keep them looking fresh for years to come.

Watch out for vegetation

​​​​​​​Any organic growth on the surface is bad news. Any ivy, moss or other greenery should be removed using a brush and the entire wall (or building if the growth is more widespread) should be treated with a wash such as weber CL150. Even if there’s no sign of growth on the building, it’s a good idea to give it an annual wash down with weber CL150, which will kill a broad range of bacterial, fungal and algal species.

Wash it down

​​​​​​​In the case of general staining, give the building a good wash using a pressure washer and a mild detergent. Take care to adjust the pressure washer to a fan action rather than a jet action as this could damage the render. There are no rules as to how often you should be washing your render, however once a year or as often as necessary would be suitable.

Note: pressure washing is unsuitable for dry dash finishes.
