Depends on the sub-surface and style of the bungalow. My advice is if the old reader is cracked and falling off to strip it all back to brick and start again. You can then apply a normal render and a resin-based paint or go for a k rend. There are multiple options and finishes, the world is your oyster.

Remove the old render, then we would use Johnstone's storm shield render, two coats with fiberglass mesh and finish with silicone-enhanced 1.5mm render paint.

Francis · Answer

remove all old render. Once render has been removed check existing brickwork /blockwork for cracks. The majority of times the cracks are caused by the substrate behind render. If all is well then clean the surface to remove dust, after that their are multiple specifications to apply a fresh new render. Every render manufacturer has a spec for applying their product in the right manner, if these specs are followed then, new finish can come with a 20-30 year guarantee.
Weber spec would be to clean the area where render was removed, coat walls with Weber rendaid , a mesh cloth can be embedded into this coat then use a burn hole roller to create a key for the finish coat.
Then you can apply any Weber finish you like onto the area.
K rend also have their spec to follow for this scenario using their products.
Get an approved applicator to apply
These products to obtain a guarantee.

David · Answer

Use the good old method of sand and cement 2 coats scratch and finish.
But see if there is any reason the old stuff was blown, you might need to rectify the wall 1st.
