It must get plenty of mixing time , approx 3 times longer than S/C too keep the water content low. back rounds must be well dampened but not wet, application time between coats is 3 days for scud, 7 days for each coat after that dampening every day, keep the coats as tight a possible, the heavier the coat the greater chance of shrinkage, ensure the final coat is well protected from rain, wind and sun for a considerable period of time. Any of the suppliers recommend you do not start external work this time of year as they have is a 90 day stand over period in which there must be no frost. It can be applied by hopper and compressor or hawk and trowel. hopper is the quickest and if its roughcast the best way of applying. Hope this gives you some idea as it can be tricky stuff to deal with
 
internal or external work

un both cases more like applying a render finish coat rather than a skim

your finish can be made up with

internal .....fine silca sand /nhl 2

external ...we use plastering sand (washed pit) and nhl 3.5 mixed 2:1

mix in bell type mixer


or as we do now buy a prebagged backing aUntitled Documentnd finish

thanks lads but i am on about internal work,i have done the base coat but finding the finish coat hard.i know i am doing it wrong..thats where i need help
 
I'm sure there are different ratios that can be used, but I'm using this at the minute and I'm sure it's a 50:50 mix marra :RpS_thumbup:

ok lets start again

if youe using hydraulic or non hydraulic lime (putty) the finish ratios
are the same
sounds like you are using nhl ..

2 sand 1 lime .....

sand would be fine silca


mix until nice and creamy ...

also make sure your background has been dampend well
 
I'm using a garden sprayer to lightly damp the walls, (never soak them!) then apply it like any other finish coat BUT then I work it with a sponge float. It can be finished with the sponge float for a more open finish or a steel to close it right in or a car sponge for somewhere in between. Then there's the aftercare, the baby-sitting of the walls that they don't want to pay for :RpS_thumbup:

Is the finish done in two coats ie one one day then a tight one over the top the next day? What have you had to do the following days? did you do the floating and if you did, did you get the gear off them also?
 
Two coats Flynny, but you can put a third on if you need to. As I said, I apply it like any other finish. It's slightly heavier work but lovely to use if you get my meaning marra. :RpS_thumbup:

I ain't an expert on lime by the way, so stand to be corrected, this is why I keep asking DANNY for a lime section :rolleyes)
 
ive done a lot of this, i wouldnt use a nhl for finish,lime putty add to that silversand ,lightly dampen the background,use a crossgrain float between coats,

would you leave each coat of finish a day? did you trowel up with a steel trowel similar to gypsum?
cheers

Yep a think a lime section is a good idea, so do you keep dampening and closing in for a few days after till it has carbonated? Is it the stuff in the tub what a posted in the previous thread also superspread do you mix your own or get it mixed then delivered?
cheers
 
You can close it in the day after and the idea is to keep it from drying too quickly by giving it a spray now and again over the following week.

Yes it's the 'Fine Stuff' in this link (£10 + vat)

It'll have a little bit of water on the top which you need to whisk back into the mix, but other than that it's ready for use, then just bang the lid back on until you need some more.

how many metres did you get out of that tub also did you float the wall with lime or was it a reskim?
 
Depends how thick you're putting it on, but you should get about 10 metres from a tub, walls were floated with lime yes, and a ceiling to overskim :RpS_thumbup:
 
Float coat was 3:1, cos I know you're gonna ask:RpS_wink:............and some man-made fibres as well. Scratch coat has horse-hair or similar:RpS_thumbup:

Did you get it delivered the right consistency, how many coats and over how many days did you leave it.
cheers
 
If it's old stonework you will be looking at dubbing out, scratching, floating, then skimming coats, all with the appropriate time required between applications.............the thumb test is a good guide :RpS_thumbup:
 
can i just add

you should not finish with steel trowel as this will bring lime to surface and also you can reduce breathability
the finish should be lightly textured by using a float or sponge to finish

I agree that a float or sponge finish is better, but you can use the steel if so desired.

I'm only passing on my (limited) experience/knowledge of lime and as I said I stand to be corrected, so the more people that contribute to these threads the more we can gain a better understanding of lime :RpS_thumbup:
