gives you more time to work with it before it goes hard. If it does go hard and you need to do more work to it, you can flick water on it and you'll be able to finish what you need to do. Be careful though, it can burn your skin!!!

most of the answers are right ..but there are some answers that are wrong ..lime mortar is used to make the the render coat more flexible ..allways in two coat work ...but never came out of a pit for render ..that was slake lime and was used in brickwork ..allso they never used cow hair ...it was allways horse hair ..and this mix with horse hair was only used on internal walls ..where the walls were constructed of hazel twigs which were woven...and the horse hair twised around these twigs and the render held better before lime sand mortar they used cow manure and horse hair

Up to 1940 that and cow hair was the only additive to sand in the plaster mix, the actual finish of the skimming was pure activated lime, this was prepared on the building sites by digging a great pit filling it with lime and water then leaving it to settle out. then the kids used to go round and throw bricks in it just to see the holes they made when they hit the lime, much to the detriment of the plasterers

Its a old fashioned plasticiser which makes the render easier to work.
It is also more flexible than sand cement render which will allow for small movements in the building without cracking, along with allowing the building to breathe.

its mainly used in old lsted buildings now as i was used as a natural plastisiser which was used for a few reasons, 1 it make mortar more plyable and easier to use , 2 it help motar epand and contract in varied weather which would help stop the mortar cracking. 3 it take longer to set hard , so there was more time to work with it

it makes the render (fatty) easier to work with, and less liable to crack.
