I have heard a few people use a sponge on hardwall... @theblones @nickelarse
@Big k...we always run straight edge over then when ready lighty sponge before running scarifyer over....
takes out any ridges and leaves it a dream to skim...
also always do the same on any chases patches etc....
unifinish is not an undercoat, it is a one coat finish. it does have a sponge float put over it to bring up the fat for final finish.The only undercoat you should be sponging is Uni-one coat.
To require a rub of a float would most likely be many mm. deep. At one time all skim type finishes would have been hard wood float applied, the SF is just a modern take on same, hardly a game changer, I know plenty won't look at an angle trowel preferring opposite walls, I think they are mad, do lovely work but, so how bad?This ol chestnut agen.
Makes me wonder just how bad a finish some must leave with a trowel to make scouring the bollox out of a couple of mm of skim on board seem like a Flawless finish.
If the walls are that bad why not give a coat of bonding first to even and fill out.?As malc says,Has to be thick too really hide the blue grit plus the staircase am doing is in a old farm house so the walls are very uneven. Sponge is good where the skim is deep in places and straightens the wall out.

Your right Malc, Thistle Unifinish isn't an undercoat, But Universal One Coat is an undercoat, which is what I was talking about, well technically it's alone coat plasterunifinish is not an undercoat, it is a one coat finish. it does have a sponge float put over it to bring up the fat for final finish.
I use a sponge regularly well the Labourer does it for meIs it just me or are people who use sponges on their finish coat plasters the roughest of the rough and give us genuine time served, quality crafts men a bad name? to me it just smacks of bad practice and low skill levels.

all well all I can say is that if you all don't that's fine...
but believe me theres many a situation where a sponge float benefits and improves an overall finish from backing coats to finish...
@Big k ref scarifyer its a tool for keying up but you use it earlier as they have bit of flex aposed to a devil float bud...
@smudge505...it doesn't add any moisture to the backing coat...
also its not the use of the sponge that makes the plaster ruff its the plaster...I could show you flawless sponged work likewise could show you terrible without..
its the plasters skill and attention to detail that counts not the tool hes using!
Each to there own I rekon as long as the job gets done neat and tidy that's all that mattersThis ol chestnut agen.
