Rendering a wall

BB1984

Hello Helpful People,
My house has been rendered externally with a smooth render. (I say smooth, it's pretty rubbish though!) However, it's evident that this was done directly on top of the previous render, which was a hideous, very rough and spiky finish.

Unfortunately, whoever did the rendering didn't bother to do the walls of the front and rear porches (walls which were originally external, but are now internal), so we've got this awful rough surface that has attracted loads of dirt over the years and looks horrible and grimy.

What are my options? I'm considering the following options:

• Giving the walls a good scrub with sugar soap and then repainting.
• Attempting to chip off the worst of the spiky bits, then skimming over.
• Rendering over the whole lot and smoothing it out.

Do you think either of the last two options could be DIY-ed? I've done a fair bit of internal filling and smoothing, but never rendered an external wall.

All advice gratefully received!

Thanks, BB.

hi BB,
sounds like you need to get a plasterer in, you have to think what you put on has to have a key to the existing 'spiky' finish or it will fall off ;-)

Hi BB, I'm interested to hear what you decided to do. We bought a house with swirly render, and I'm thinking of chipping out the swirls and then repainting. Would be interested to benefit from your experience.

Thanks in advance

Difficult to see without looking is it plain faced render ie rubbed up to a sponge finish?can you post a picture,
you can render over if its sound but the problem might be your bellcast beads above the dpc level

cant sand and fill external render it will look terrible when daylight shines against it

the term skimming is only for internal use,as it means a finish coat of plaster

i wouldnt advise rendering as a diy job as it looks terrible if it isnt done right.

You could always direct bond plasterboard to the walls and then either tape the joints, if you use tapered edge boards or have it skimmed afterwards with a coat of plaster.
