[eels_up_inside_ya]

hi lads,hope your all good,just trying to pick your brains a bit.ive got a rendering job on wednesday,just wondering the right mix for scratch coat and top coat onto clinker block?and how long to leave between coats.be everso grateful if you could help us out,cheers guys

4:1 scratch , 5:1 top coat , always works for me - Ideally leave a couple of days between coats but normally top it next day depending on urgency of job

[pristineplastering]

I think its another name for breeze blocks Nicksey - Could be wrong though

 

[eels_up_inside_ya]

Rendering seems to be one that different people have different ways of doing it for the scratch coat i have been adding fibres like the stuff you get in screed seems to strengthen it up and stop cracking (well thats what i tell the customers ) 4:1 and top coat 5:1:1 the extra 1 is hydrated lime and sand is holme sand i always add waterproofer to both coats and most important let the scratch coat cure before you topcoat
