Hi I was wondering if someone could give me some help on troweling. When I come to final stages of troweling (pretty much rock hard just before it goes brown) ill give it a trowel with little water and small hollows seem to appear when I go over it. Its like water is trying to push out from the plaster. Anybody no what I'm doing wrong?

Hard too say without seeing but are you troweling a bit late....leaving your wall to go rock hard and wet troweling just before it goes brown?

Sounds like you haven't closed it in enough before it has got to that point, second coat, 1 wet cross trowel, 1 wet trowel, then a dry or just a wipe of the trowel if it needs it to allow the trowel to glide. You don't want to over trowel it especially with splashing water on it so late as that will create hollow if you don't hard trowel them out..

Ankers, You've left it much too late for wet troweling. When the plaster turns brown it has set and there's nothing you can do with it anymore. These are the stages a beginner should be following:
1) Lay on first coat.
2) Wash tools, bucket and spot board.
3) Lay down lines in first coat.
4) Lay on second coat (slightly wetter mix).
5) Wash tools, bucket and spot board (leaving a small amount to fill in any hollows).
6) Lay down lines and fill any hollows.
7) Wait 10 minutes.
8) Lay down lines.
9) Test surface of plaster, run your finger gently across the surface, if it tears then it's not ready for a wet trowel.
10) Wet trowel vertically (if the back of the trowel accumulates too much plaster, it's not ready yet).
11) Wet trowel horizontally.
12) Dry trowel.
1) Lay on first coat.
2) Wash tools, bucket and spot board.
3) Lay down lines in first coat.
4) Lay on second coat (slightly wetter mix).
5) Wash tools, bucket and spot board (leaving a small amount to fill in any hollows).
6) Lay down lines and fill any hollows.
7) Wait 10 minutes.
8) Lay down lines.
9) Test surface of plaster, run your finger gently across the surface, if it tears then it's not ready for a wet trowel.
10) Wet trowel vertically (if the back of the trowel accumulates too much plaster, it's not ready yet).
11) Wet trowel horizontally.
12) Dry trowel.

I will print it off and ask myself to tick off as I do each task, I simply put on first coat,flatten, when it pulls in,I put on second coat,flatten,let it pull in ,flatten,when its ready for wet trowel ,I flatten using wet brush,when its near end I do wet brush and flatten,when its almost dry ,I trowel without water. Every wall and ceiling can be different on every day, due to background,heat,weather,preparation,how long it has been left,humidity,your mood,energy level,material used,music been played,the money involved,what's on your mind,trying to remember **** you read here etc

Very simple,just add practise ,add wanting to do it right,add caring for the person who is putting money in your pocket,add thinking long term,do not just grab a wage and run,be clean and tidy,helpful and respectful. Remember it takes time to be a decent spread.

small hollows or bumps?? coz they mean diff things...
Follow advice from minh and john. They telling you the order of things.
The small hollows you seeing is the plaster tearing. You moving too far without water to lubricate the trowel or you got the trowel open too much or you applying too much pressure. No water = friction and too much pressure = friction and trowel open too much = scraping and you end up tearing the plaster mate :RpS_thumbup:
