Rerendering a cracked wall

[steve1976]

Have a job to do for a mate he gettting his dashed wall raised up 2 blocks and wants the whole wall rubbed up smooth, now the dash is chipped off back to the blockwork , there are some cracks on the wall , i was hoping just to eml cracks then coat as normal, is there anything else i can do to stop cracks apprearing again?

mesh the cracks then fully mesh the wall?

 

[steve1976]

The walls bout 30 or 40 ft mate would you still mesh the lot

 

[napper83]

personally no cos im a lazy f**k*r and just mehsing the cracks would be sufficiant i would think

Paper and mesh the cracks if they are movement cracks or just mesh them if they are impact cracks.

theres that helical bar stuff you rake out the joints and bed it in.. supposed to stop it going any further..

alkali resisatant mesh , mesh the whole wall you shoild be able to get the ,mesh from a good plaster supplier (or anywhere that sells monocouche renders) if not lord and downing sell it by the roll and there's is good gear as its easier to press into the material, it doesnt take that much longer to do it either just press it lightly into your scratch coat

Was looking at that helical crack repair stuff 100 quid bit dear that , wonder if you just used exterior filler then mesh

 

[southernmonkey]

roll of mesh is about £50 mate and does 45m2

not surprising.. tbh i think its designed more for older buildings suffering from slight subsidence (cracking across the joints with the joints getting wider and wider)
sppose it depends on the cause of the cracking..

i think the diameter of the holes is something to do with the aggregate coming through
