Render, when relating to buildings, is the plaster coating on the outside of the house that acts as a kind of ‘skin’ or layer. Buildings may be covered in render or K-Rend to protect them from the usual elements, pollution and plants or so that the exterior of the building can be painted without the paint going directly onto brick.

Like all buildings, rendered buildings need maintenance, cleaning, painting and general upkeep. Some render buildings will have storage (like sheds) leaning up against them, and when they’re moved the dirt and buildup becomes much more apparent. Obviously, this is not ideal and would be the perfect opportunity to clean the render. Cleaning render or K-Rend can be done by softwashing, jet washing or blasting with a power hose, but it may damage the render and is usually best avoided. Wet weather exacerbates the growth of moss and algae on render, so spraying it with more water will not help in the long run. The best render cleaning will come with a pre-treatment to protect the render itself before the dirt is cleaned off, often using a softwash. There are environmentally friendly options available to prevent any additional pollution and keep harmful chemicals away from homes.

Render painting is best done after the render building has been washed and properly cleaned. If the dirt and pollution has really affected the render, there’s a good chance it will have damaged the paint, too. Therefore, we would recommend a post-way paint job to get the render looking as good as possible. It’s also not necessary to wait until the old paint is chipped or peeling: many people get their render re-painted to change its colour, possibly as part of a rebrand for businesses or redecorating a home.

Restore or redesign your rendered façade with a sensitive solution

Technical fabric advice, evidence-based support or a fresh perspective! Talk to Us Today.

    We provide complete restoration and maintenance solutions for cleaning, repairing, and protecting rendered façades. Our methodologies comply with BS 8221-1:2012: code of practice for the cleaning and surface repair of buildings and BS 6150:2006- A1:2014 for painting.

    We ensure the correct treatments and repairs are undertaken to your façade, including the removal and replacement of the failed, weak, and defective areas of render.

    Pro-actively managing organic and visually unattractive growth on a rendered façade reduces the need to clean the building as the treatment removes the root causes of the discolouration and decay on the rendered façade. We apply a specialist cleaning agent that absorbs into the render to break down the algae, lichen, and moss spoors. Once applied, natural weathering processes provide a highly effective maintenance clean for rendered facades. On porous render the surfactant active will penetrate deep into the material and can be treated with light steam cleaning to create the final product.

    To redecorate render we use colour matched pigmented silicone resin coating and painting systems due to their flexibility, quality, and durability. The coatings also contain a film preservative to help protect the façade from further infestation and growth of organic matter. The façade painting systems applied are water repellent, breathable, self-cleaning, non-streaking, and UV resistant, providing you with a complete protection solution.
