Here’s how to paint on RhinoBoard


Good day, the upper bedroom in my house was built with a board which looks like RhinoBoard. The paint is coming off and I need to repaint it. What can I use to make the paint stick? This is the outside walls. – Jan


Good day to you, Jan. I am sorry to hear about your problem with peeling paint. I will have to assume some information because I have not seen any photos, but have a pretty good idea what it looks like.

I think a loft room was added on top of the existing walls with a timber construction, and the walls were constructed with a 9.4mm RhinoBoard.

I think that the peeling paint is a result of poor workmanship and that the surface was not prepared correctly or no primer was used.


Remove all the flaking paint with a scraper, though I do not think that you will be lucky enough to remove it all. Sandpaper the surface which will also remove some old paint. The finished surface will now be uneven.

Remove all loose nails and install drywall screws in new places. Use a steel trowel to apply a thin coat of “skim plaster” which is available at hardware shops.

Now it can be treated as a new surface and you can decide what type of paint you want to use. But remember to use a primer before you paint it with good-quality paint.

If you are unsure about what maintenance to do at your house, or how to do it correctly, you can request a maintenance inspection on our website www.gautenginspect.co.za.
