what would you think about. battening an external wall. mineral wool/rock wool inbetween. then lath and plaster using lime mortar. is this stupid idea or would it make sense?
Hi @therestorationcouple. I have hygroscopic salts around my chimney breast in my Victorian terrace. Would you say that following your method of lime plastering could solve the issue of the salts 'blooming' or do you think this would happen if I simply just applied lime plaster over it (with the damp having dried out as much as possible of course)
Would you guys please speak ENGLISH…. 😳… jk.. actually wondering if there is an USA 🇺🇸 equivalent for this product? Curious about the r value when using it as an insulator.. thinking of building a stone house that can breath… don’t want to wrap it In styrofoam ya know? Thanks..
Hi guys, great content. I hope you have time to answer my question. I have wattle and daub wall with lime plaster render, the plaster is blown and crumbling, the wall is situated in the upstairs hallway where the banister is, an internal wall. I was thinking of treating it with bonding, fibre glass mesh to fix the broken areas then apply multi-finish to skim coat the entire area, as bonding and multi finish plaster in not really breathable material to use. Is it important to have interior walls breathable? 😊
No thermal value gained by using hemp plaster it is only lime NHL2 or 3.5 with hemp fibres over priced mortar, get equally as good results using appropriate hydraulic lime, with good quality coarse sand and well fibered with hair or sisal. Or use premixed lime mortar with salt inhibitor added. More expensive but no fear of efflorescent salts, finish with putty lime 2-1 silver sand or premixed finish
Very pleasing to watch. Q: how much lime mortar did you apply before starting your plastering ? Did you apply it just in the large gaps or also in the smaller crevices ?
Have you found that the lime/hemp plaster actually provides some insulation? I have an old stone cottage with 2 foot thick walls and want to maintain the breathability but not have huge heating bills!!
Hi, great video, I have had a dilemma in that I bought a house for my family, Victorian mid terraced, 1900 build, the property was allowed to get into disrepair and empty for a while. I have since stripped every wall back to brick, removed all flooring ground floor and all ceilings, in effect the house is a shell. I have been told I have rising damp, which is not noticeable on the brick work only the metre that they use. I am replacing all the sash windows to new timber double glazed, and a number of plasterers have suggested 20mm cement render then 5mm skim plaster for all walls, then by others been told to plasterboard dot and dab, concerned on renovating the entire house then have issues, so would you recommend hemp for front and back and cement and skim for internal walls, also on internal wall there are couple of chimneys what would you use on them?
Not sure whether to do damp proofing treatment since I have already stripped back to brick anyway.
Hi. I have been trying to find out more info on this . I have a Scottish house mad of flag stone . Walls are 3 feet thick. Where can I find more info. Is it a good insulater?
Hi Tim, I'm currently renovating a 1900 Victorian property in South Wales. I'm looking to repair and replace the old blown and cracked plaster on both external and internal walls.
What lime hemp plaster did you use, as in hydraulic vs non hydraulic, medium/fine etc
I'm looking on doing the scratch/float coats myself and getting a professional for the final skim
hi. first of all im waching all of your videos they are amazing!!! can finish coat be layered with lime nhl 3.5 powder? if yes what is the ratio mix? many thks
Tim, if you don't mind me asking, how much was this lime plaster to the wall you are showing? I am plastering my country cottage soon so it would be great to know as was planning on gypsum skim until I saw your video!
That looks a great job, it's good to see someone doing it properly. My customers are constantly asking why their 100+ year old houses are damp, I always tell them the same, modern materials used in the wrong way. Gypsum and cement pointing cause so many problems.
I'm sure you'll have hear of Keim mineral paints by now, but if not look them up. Acts like modern paint but 100% breathable, and not that expensive. And you don't need 10s of coats as with limewash, and you can have almost any colour.
Great Video, I am doing something similar with my 19th century cottage, just wondering did you install any vents in the external wall? I'm tempted to knock a hole through just to give the room some additional ventilation, thanks
use a concrete chain saw and fit a plastic damp proof course right through the walls in 1m sections and overlap. Water fed no dust best possible solution. Do the same with internal walls 8mm cut so no problem with movement if re pointed properly in 1m sections with gun. Cuts like butter . Diy job £2000 for machine sell it on when done. Don't buy the cheap chains . £300 each Not expensive as it will be a proper cure for rising damp. Penetrating damp, point outside brick work, ventilate house every day for 2 hours open a few windows to get the draft through, morning best before heating goes on. fit proper water covering cowls to chimney to prevent rain getting down the chimney and open up closed off fireplaces. natural ventilation. Use Lime wash and lime render after removing waterproof render or none porous painted render. as it keeps condensation in walls and stops the house from breathing vent the tumble dryer outside. Fix the gutters. Clean out the drain traps. Dig a french drain around the hose and fill with large pebble. Let the sun see the walls remove trees etc that block the sun. Lower soil levels that are above floor level. If you have green mold it's not rising damp as the salts in the ground water rising up from the ground would prevent the growth of mold. Green/ black mold is penetrating damp or usually just condensation from lack of ventilation. Phil
Good work! However you cannot speak of insulation when the layers of hemp/lime is that thin. The U value is ridiculous so is the R value. However that texture will give a warm feel which will increase the confort.
hi, what did you use on the corners?
Hi , what coverage rates did you get with the lime bags?
Great video and well done answering everyone's questions.
what would you think about. battening an external wall. mineral wool/rock wool inbetween. then lath and plaster using lime mortar. is this stupid idea or would it make sense?

nice. That would be brilliant over AAC blocks for new construction. wonder how much R-value this adds?
Hi there we are facing the same job as a the old plaster is damp on all outer walls. Is the final skim just made from normal gypsum?
Would you guys please speak ENGLISH…. 😳… jk.. actually wondering if there is an USA 🇺🇸 equivalent for this product? Curious about the r value when using it as an insulator.. thinking of building a stone house that can breath… don’t want to wrap it In styrofoam ya know?
Thanks..
What was the Final Top coat please?

How is this insulation? It's the same as your other upload?

hi how is your experience with the wick now in 2019. we we try the same with our wall and want to hear how it has been.
Is it possible to you use this over an already plastered wall albeit roughly plastered ?
Interestingly video…. But your electrical wiring should not be running horizontally. Naughty!
can i use cement instead of lime?
Are you putting sbr first?
Hi. I have been trying to find out more info on this . I have a Scottish house mad of flag stone . Walls are 3 feet thick. Where can I find more info. Is it a good insulater?
Can you lime plaster over thermal boards?
Wish u were in USA

HI, was a 100kg enough to to cover that area ? 1st and 2nd coat.
Thanks and great vids and very helpful
Very nice job.. did the hemp lime plaster make a noticeable difference to the relative humidity and warmth in the room?
looks like you were doing internal not external , wrong video or wrong title ?

This is truly remarkable.
