Render Cleaning Chemicals


Render cleaning chemicals can make a dramatic difference to the appearance of your house or any building and technological advances have made products safer for the environment and operators in recent times.

Whether it is a dwelling or school, has K-Rend coloured or painted render, pebble dash, harling or roughcasting, the walls will tend to suffer in our damp climate and need an algae remover or may have a whisky storage bond nearby that makes walls and window sills go black with mould.

Render Cleaning Chemicals

Green algae, pollution, dirt weathering and atmospheric traffic film are other factors to consider that can turn beautiful light shades and colours black or green and unsightly. One answer has been to apply a biocide-based chemical to kill the spores and algae on the render; this is often marketed as ‘soft washing’ and then leaving the weather to wash off the dead algae.

Ultra-Safe Render Cleaning Chemicals

RenderKleen is an innovative product that is part of our render cleaning chemicals range along with 4 others and is used for cleaning render via a very different process to the use of biocides or sodium hypochlorite. This is a non-toxic, odourless and non-hazardous aqueous cleaning solution that uses millions of nano-energy packages in the mix to penetrate under the soiling and algae on render to dislodge it and loosen it off.

The contrast to the killing action of biocides is the key factor in why our render cleaning chemicals are so safe to use. Biocides are disinfectants and while ‘hypo’ as it is called, is effective, it smells awful, the fall out kills plant life, ruins clothes, and who knows what it does to you, the operator?

Render Cleaning Chemicals

Using our chemicals means a quicker cleaning action and the process is very safe as the chemicals are food safe for operators and pets, lawns and even for aquatic life if they land up in a water course. Workers using RenderKleen render cleaning chemicals do not even need PPE, there are no hazard warning pictograms on the packaging and the product is delivered to the site in 5 litres or 20 litres jerrycans at ready-to-use strength for convenience.

A situation that could have been tragic with any other render cleaning chemicals arose where a contractor used a rubber tube and his mouth to try and siphon the chemical from 20 litre jerrycan into smaller bottles and got a mouthful which, in his surprise, he swallowed, and, apart from a funny taste, was fine!

How Do You Apply RenderKleen?

It can be used by spraying on generously and several times or brushing with a Gardiner-type long-reach window cleaning brush pole then agitating with a semi-stiff broom or brush to help dislodge soiling, you will note a light foaming occurs that colours with the debris.

After this leave for 5 to 10 minutes, wash off, and reapply by sprayer – we always suggest that you try a test patch first. The products are ideal as a painted render cleaner but please be aware that if the paint is in a bad state, it can easily remove some in the same way it will give algae short shrift.

Can I Use A Pressure Washer?

Yes, you can – the key point is to use the pressure washer on fan setting and gently so as not to damage the render and do not bring the nozzle of the lance to close and concentrate too long on a small part of the render to not cause damage to the K-Rend.

Our eco-friendly render cleaning chemicals combined with a pressure washer makes a lot of sense as it helps penetration and, as RenderKleen can often liberate A LOT of soiling, you want to wash this away rather than letting some of it dry in situ – you can also use a standard garden hose for rinsing down.
