hi there just joined can any one tell me if you need two coats for rendering external wall if yes do you need bonding and watterproofing on both coats
i mainly render inside (for damp proofing). outside i've done mainly garden walls and a bay window.
on the outside i use bonding on the 1st coat only applying a light strake to key the 2nd coat. both are at 6mm. i use 3:1 for 1st coat and 4:1 for 2nd coat (i believe you can use 4:1 for both coats). i use waterproofer for house walls in both coats. i put the 2nd coat on just as the 1st is setting. i also use plasticizer and washed sand.
thanks i will give it ago my other problem its abt 30 met long 3met high i was wandering if i could use beads t0 keep it level spaced out at equall sizes
