;D it finishes render mate if you close it in you wouldn't need a float ( using this as an example always use a float!) the sponge brings a little sand to the surface and smooths the render , i think youre confusing yourself with one coat skimming mate .......then the sponge is used for the car ;)
 
To get a nice flat finish always use the float. The sponge will only follow in the shape of the wall while the float will straightin it. Might look ok if u sponge it but it will be a mess when the sun hits in :P
 
when the wall has been ruled off, a poly float is used, then a sponge is used, but ive seen people use a regular sponge and ive seen people use a sponge float, just wonderin which one is best.cheers
 
Sponge floats come in different grades coarse, fine or medium natural sponge is best the fine stuff, i use a round gyproc jointing sponge does the job sponge floats are for one coat plasters
 
just use a sponge mate, try not too use a jumbo sponge they tend to bounce around if you go in travis they do decorating sponges that are perfect
 
all depends how skilled you are at plastering/rendering and what u are rendereing, if its over st blockwork, I can 2 coat same day, and use a bath sponge, and leave a good job, but to do this u need to be useing double washed plastering sand, and fairy liquid, imitations dont work,

if you cannot get 2 coats in 1 day when scratched up it will be very hard to top coat render to a prfect level job and bath sponge, but it still can be done,

some plasteres need to rule off before leaving a good enough job
to sponge but like I say it depends how skilled you are, on old work its a different game you need string lines and all the gear

I once worked for a specialist render firm with very big money earners £1200 per week average 12 years ago, when i first started for them I had a feather edge and darby and they laughed at me


in the old days it was a wooden float we used
 
surely if u dont u a feather edge it looks shite, also was a wooden float used in the same way as a poly float
 
yes mate it was used in the same way,

as for looking chite no m8 it ts a good job when completed correctly its the same thing with internal plastereing, you are taught to use a feather st edge, on float and set, old school plasterers would only use a darby, never a st edge
 
ive not been in on this yet but can i just say that i never use a sponge on render, internal or external... i find it doesnt help me, cos i gave some a rub with one once and it made it look worse!!! i float it soon as its ready and if externally it needs to look real pretty, just when its gone too much to float i run my skimming trowel over it... are you spongers (sorry ;D) getting a similar finish??
 
we always use a float so it gets nice and flat  and then give it the sponge treatment looks the b*llocks when its finished,always float it before you give it the sponge though and always have used jumbo sponges
