iv got 150 sqmtrs to do and would like to know the best place and price to buy this from and how many bags will i require? as im still trying to work out if this is more cost efective and a better product than s&c and can you use either plastic or metal beads for this.also hacking off old stuff first so would i need to sbr the block work or just spray and clean off with water and wait for it to dry and can i still use mesh in with this product.advice really needed on this guys:RpS_scared: as i am thinking of using this on a regular basis
