Afternoon everyone , hope everyone is busy . just wondering what you more experienced guys think really . i picked up a job last week to re render a front of a house , customer hacked it off ( which suited me just fine lol :RpS_wink. Now its being done in sand and cement ( the house is built of stone by the way ) , now i was gonna use a 4 to 1 mix on the scratch coat with waterproofer etc ( 3 in 1 ad mix basically ), probably have to put on a 2nd scratch coat then , was gonna use another 4 to 1 or maybe a 4.5 to 1 ( with waterproofer etc again ) , then for the top coat i was gonna use a 5 :1:1 ( sand , cement , lime ) or maybe a 6:1:1 mix . ( it's a fine down finish by the way ) . just wondering wat you guys think of the mix ratios , my m8 normally uses 4 to 1 on every coat , but surely thats to strong on the top coat and is just asking for crazing and cracks everywhere :RpS_scared: . i was always taught those ratios anyway . and whats your views on waterproofer in the top coat ?? yes or no ??:RpS_unsure: i've also been hearing about throwing some fibres in the scratch mix ?? any thoughts ? im just trying to cut down the chance of heirline cracks and crazing basically :RpS_lol:
