How to fix Hebel render?

Just Starting Out

How to fix Hebel render?

Would like to fix the hebel render. Paint is bubbling and coming off. Really small to repair so hoping will be straight forward.


I have the paint but not sure what to use for the sand texture.


I think my builder used Dulux Acratex sand.


Repair area is small 50mm W x 50mm H

If you have the colour right to match.

Find a small brush with preferable stiff natural bristles.

Dip the brush in your freshly painted wall and pull it back out, that should give you a pattern.

You might have to have a few tries to get the pattern right and posibly hold the brush on an angle.

Re: How to fix Hebel render?

Hello @Janikage


Thank you for sharing your question about how to fix Hebel render.


It's great that you've received excellent advice from @Brad. I recommend using a 100mm Sharp Edge Paint Scraper to remove the paint that has bubbled. Once you've removed the paint, give the area a good clean with a stiff brush. If you still have some of the Dulux 10L Fine Texture Exterior Paint, make sure to stir it very well to get the sand texture to mix with the paint. Using Brad's recommendation, use a stiff brush to paint the texture onto your Hebel block. I recommend painting it around noon when all the humidity in the Hebel block has been dried out. Please keep us updated, we look forward to seeing your Hebel wall repaired.


If you require further assistance with this repair, please let us know.
