"You can repair cracked render .if your repair has fallen off a couple of times then the backing is either got no suction/to smoth or your render is the wong mix . If baddly cracked you can use a hellibar system in the morter bed joints other wise you can fix expanding metal lath on to the exposed surface .drill and plugged then re render. Other wise brush on sbr liqued ,scratch coat with a slurry coat of sand cement 3/1 mix ,leave to harden fore a couple ov days then top coat with a 4/1mix ov sand and cement render . Any of these methods will work"

"It can be repaired. But there are alot better products to use. On external render. Rather than sand cement over time it breaks down."

"Cement renders can sometimes be removed by working over the surface with a hammer, aided, where necessary, by a chisel. Great care must be exercised. If large sheets are levered off, soft underlying materials may be seriously damaged. Various power tools can also be suitable but only in highly experienced hands."

"Yes ofcourse it can be taken back around the damaged area to the closest solid bit of render then re prepare the background and scratch coat and top coat it back on"

"Yes I'm sure it's repairable but it's difficult to say what needs to be done without inspection"

"Yes it can, but will need to b aware once taken off the cracked or blown parts can end up going on and on, u stop once u hit solid parts of house witch is unlikely in most jobs, if its blown or cracks ur better off doin whole job, a patch up isn't always the best option, cheapest, if your goin to do it, do it right first as last, or the house will always be patched up,"
