Approx400m2 plastering to do , some is bare stone walling approx 2ft thick which needs lime render and finish , some is bonding scratch coat and multi finish , some of the lime render has fallen off the stone work . Can I patch up with hydraulic lime and sand render then PVA and bond over and scratch the whole area ready to receive plaster multi finish ?
 
Hi guys my apologies its my first thread , I've not even introduced myself properly , I'm stogey from Leicestershire landed a cracking job apart from the lime rendering ( unfamiliar territory but need to know a bit more than I do , any advice other than a 2 day course which I've just looked at ?
 
You shouldn't put gypsum over limework if you want it to work properly stogey........... Welcome to the forum mate and get on the course it can't do any harm :RpS_thumbup:

Oh dear.........I've just endorsed going on a course :RpS_scared:
 
use haired course stuff floating coat course stuff finish fine stuff dubbing roofing tile hope this is some help to you www. Plasterinlime. co.uk
 
Thanks a lot everyone , I'm going to the Brecon Beacons for a 2 day introduction and practical course on lime rendering and finishing , I think it's money we'll spent and should save me getting spanked on the forum , cheers for the welcome , I will post some photos of the property .

hydraulic lime clean washed sharp sand synthetic fibers are easier to use than horse hair etc mix up the day before and the fat will make the mix nice and creamy to spread the next day mist each coat down for a least 7 days test thumb of nail rule before applying next coat dont use any pva at all buy pre maid lime putty finnish for top coat .start with 2 half to 1 mix first then weaken mixes as you fill out with fibers in helps with the shrinkage, give every coat correct drying time try to keep coat to about 10 mm ,mist down before each coat

Hi lads , stogey here , I had a great result regarding the 1600 century cottage , I had a visit from a specialist who put me through my paces with the lime render coats , 2 x 3.5nhl /5 x washed graded sand , we used (Baston sand) lime mortar pointed stone first 1x 3.5nhl 3x washed graded sand , Dubbed out low spots , mist over when thumb nail dry , apply render coats x2 , prick up , nail dry , float coat ready for finish . Thanks again for all the advice , so pleased I joined the forum.

get some pics up on here as the job progresses marra....................:RpS_thumbup:
 
How many jobs have you been to, plastering over internal walls (solid walls) give a price to do it properly in lime and someone undercuts you doing it in gypsum and you end up being called back in 3 months to put it right cos of damp! Also sand and cement rendering external walls causing more probs!
Allot in mid Wales with old stone houses and farm houses.
 
How you doing jv , I originally didn't know much about lime render and plaster which is why I came onto the forum , I hope more people get smart and sign up , not just to get information but to also share their expertise in return and help eachother out , the job I am on , somebody has completely destroyed the external stonework by using cement mortar it has reacted and damaged the stonework, unbelievable, we are going to grind out , turn some of the stone and re-point in lime mortar .
 
Agree mate! People and plasterers are becoming more wise to the need to use lime and the benefits. I was lucky enough to learn lime first with my G dad. And went on to gypsum later. Hard work and heavy stuff but well worth it!

Still hard work to explain the difference between gypsum and lime to customers, must sound like I'm trying to con them!
 
hi there im new to this forum. im too a lime plasterer witch learnt gysum later. i think it was best, keeps you in work more.....had a job recently thou that was this new external chalk,lime, hair mix. put over fibre boards. apply 20mm and trail.....for days....wasnt sold. laths,sand,lime anyday!
 
Customers will thank us in the long run , they will see that they have been conned by others mate when the damp starts to come through and they have to pay out again to get it done properly ( lime render ) or ( lime plaster ) or ( lime mortar ) the past used to be lime , so is the future .
 
All good to speak to others with the correcT views. Keep it traditional JB. There's a reason why lime plaster has lasted over 100 s of years.
Architects should specify lime in old buildings and barn conversions over this plastic walls with stud and PB. Sweating building and loosing 4" off each wall! Crazy!
Keep at it and it'll come around.
 
What is the best way to mix a proper lime render cheaply, I have not used it myself , I only used the hydrated stuff in with the San and cement, the tubs and pre mixed lime render are expensive as far as I am aware

You can slake the lime yourself john which brings the price down but it is a long process and it is years since i did it ( and only did it the once with a very old hand guiding me) if i remember correctly minimum six weeks before you can use it for best results.
 
If you want lime putty like above then would agree more hassle, buy tubs! However if you are mixing sharp sand, lime and hair or hemp then can be done in mixer. Mix dry first for couple of min then add water. No other additives. You can get a good finish using a 5 - 2 mix sand - lime on top coat, about 6 mm thick. I post some pics of recent job done this way.

do you ever use a steel JV for finishing? I usually put a 2-4mm finish with 3/2 using wooden float or then next day on top of this a fine finish of regency lime with my steel.
I have a DVD from st Astier that shows a spread mixing white gypsum into a lime putty then applying to a floated lathed wall with a steel.
 
Yeah finish it with a steel. Nice finish ready for lime wash. But have done lime with fine sand to a coloured finish also with steel.
 
yes lads its good to know the old stuff im off to barbados again in july for 3 weeks doing another plantation house... well teaching the locals how... not getting that $hit on my hands
