House Rendering

Question

I have a semi-detached property and the render is coming off in places around the window. It looks sturdy elsewhere and it doesn't seem to extensive that it should all have to come off but can you patch these bits? How do you know If the render is in too bad of a condition, what do you use to patch?

Any help would be appreciated.

If the wall sounds hollow around where there’s cracks, or the render has come of, then the whole lot needs to be taken of. With trying to patch a render when it’s dried, and painted you would most probably see where the patch is.  My advice would be to take it off, and do it again using mesh in the scratch coat to stop cracking.

if you tap the render and it sounds hollow it needs to come off

Paul · Answer

Yes it’s possible to patch only those bits it is also possible to render over the top of the rest each job is different though

No, you don’t have to take all render off. You can remove loose areas. To check if render, do this by tapping areas and if it sounds hollow it has blown and will need coming off in areas affected. Depending on how much of the render is like this do you take it off fully but if it is only small areas Have it out back to brick brush PVA into the area and use sand and cement to fill areas. Wait for it to dry but not fully, flatten with a float and use a car. Sponge and Lightly rub over all of the sand and Cement

You have to see where the  patches are.   Is there  any more cracking, at the extended end.  If not you can patch them, making them rounder, and  winder without problem.

David · Answer

You can patch , with cement render , depending on how loose the edges are.

A  simple hammer check would show where needs to chipped off, and patched. if the majority off it was boss, which means loose, you would benefit from getting the whole panel re done.

IF YOU ARE HAVING  WATER EGRESS, THE LIKELYHOOD IS THAT YOU WILL HAVE WHATS CALLED BOSSED AREAS,  POCKETS OF WATER, OR LOOOSE RENDER ON YOUR BUILDING.
