Removing Rendering. Best Way.

[conny]

What is the best way to remove rendering?
Its firmly fixed all over, no hollow sounds when tapped with a hammer.
Tried a small section with a club hammer and cold chisel but it literally bounced off! Its like concrete!
Will a Kango hammer with a chisel bit be best way to avoid damaging the underlying brick face?
House was built around 1945/6
Its the entire front elevation, approximately 20' wide by about 20-25' high
Although it feels firmly attached the actual 'finish' looks like an apprentice has done it as a training exercise

You'll wreck the brickwork and it'll take you weeks.

You can clean up the face with a specialist coating.

Thanks Joe.
Had considered getting another coat on top.
The so-called pattern on it looks like whoever did it just let their kids design what they wanted to in it.

it will either be easy or it will never come off!!! you'll know in the first 2 seconds. If you can take it off then get it off, but if its solid, then go straight over it. Where in th country are you? that may tell us what sort of sand/cement you have on.

Heres an example.

I live in west yorkshire ( huddersfield ) and a old guy asked me to look at his bathroom. It was art deco style tiles and windows, from the 30's. He had spent two weeks and hacked off about 1 sq m. Im a 33 year old fit (ish ) plasterer, i had a go, and gave up after 5 minutes, the tiles were put on with sand and cement perfectly , and i mean perfect ( wish the tilers today were like it. ) So all i did was bond out the areas that he had got off, and he was then tiling straight over the top of it all.

Then next step would have been semtex.....lol

Again if you inynd to render it again and it comes off easy, then take it off, if its solid, leave it and cover it.

just realised your in liverpool

I'm not to good on liverpool "sand" but as your not far from me, maybe it the same stuff they used round here, which i reckon is quite hard.

Thanks Bradleigh. A couple of years ago I stripped the internal plaster off the front living room and discovered a blanked off air brick just to the left of the window. I drilled through with a long masonary bit to find the location outside in order to open up that side. Hit the outside render with a 4lb club hammer and a 4" bolster chisel. IT WAS SOLID!!!!!! Proceeded to bang the rest of the render with the club hammer and got the same solid ringing tone, no hollow noises anywhere. We've been here about 15 years now so whoever did it made sure of a secure fix!

Just removed render and dashing [two coats] on kitchen extension, came away in sheets from block-work but took about an hours per square metre with a Hilti. Damaged brickwork, but was being rendered again.

If the render is solid and unpainted the you you could use a polymer modified base render with a mesh re enforcement and top in whatever decorative finish you desire, wether it's a modern flexible acrylic, pebble dash or brick effect like the following
