How to clean mould on Hebel?

[gazetry]

Is there a render for Hebel that offers good weather resistance? What can I use to remove the layer of mould/ mildew?  Thank you.

Hello @gazetry 

I suggest using 30 Seconds 1L Outdoor Cleaner Spray (larger bottle available) in combination with a Mr Clean Handheld Iron Scrub Brush to remove the mould on the surface. For continued protection and maintenance, I recommend using 30 Seconds 5L Spray And Walk Away Concentrate. I don't recommend sealing the Hebel surface as it will trap the paint onto the surface and could result in staining. With regular maintenance and the use of 30 seconds on its surface you should be able to keep the mould and mildew from infesting your Hebel surface.

If you need further assistance, please let us know.
