5 To 1 Cement Mix

Well put it like this we did a rendering job and i had a labourer who was a newby and he was mixing a 611 mix of sand cement and lime and he ran out of cement and and never told us so just added more lime thinking that would be ok and we had to knock the whole lot off and start again because it just crumbled off the wall just hadnt set at all lime helps with workability thats why we use it.
