Water used in any plastering job should be fresh, clean and free of contaminates.

Water with a contamination of recent plaster mix residue will shorten the time of hardening more than older plaster mix residue.

Water used for the trowelling process should also be clean as it can accelerate the hardening process giving unpredictable outcomes.

Too much water used in the troweling process can contribute to blistering.

Do not flick water on to a wall. Use a broad damp brush once the plaster is hard enough to have water applied

Water drawn from a pipe laying in the sun or a black water butt can be of a high enough temperature to accelerate the plasters hardening process also.

It is not necessary to use masses of water in the cleaning process of tools and mixing buckets. Water can be re used for cleaning.

Never pour waste contaminated water into the drains. It will settle and harden in traps and u - bends.
