hi
got an old cob construction cottage the kitchen at the moment is completely tiled i want to strip and refit a new kitchen with just splash back level tileing
i want new flat walls ,so need to remove the old tiles,can i dot and dab a plasterboard finish on cob and then a 3mm skim ,or would i have to batten then pasterboard
whats the best way to acheive a new flat surface on cob the walls are not plumb! and you can see this without using a leve LOL thanks

Why dont you use the fact you have a cottage and have it rustic, but if you want modern you wanna check that it aint listed first
 
definitely not listed ! the wall out of plumb needs wall cupboards on and its in the region 2-3 inches out top to bottom ,think estate agents refer to this as character LOL
 
cob is just mud straw and stone and they rely on being a bit moist otherwise they would crumble into dust, its basically a playdough house
 
Aint being funny mate but Cob is pretty specialised even though it is a trendy way to build it is a very old method and i dont know what new methods are compatible, is there not a Cob website you could ask this Question on? There are a few lurkers on this site maybe one who knows will poke his head up. Good luck.
 
Cob must not be allowed to get damp , this is disastrous to a cob building. Plaster it with lime straight onto the cob, do not use cement. Any plasterer who works with lime and knows their stuff will be able to do this.
First place to start is with a phone call to your local conservation officer who will give you a list of people who can do this type of work.
Use a breathable paint to finish.

If you plan on doing the job your self I would be happy to talk you through it.
 
I use a slurry of putty and sand, basically a slurry of what ever I am plastering with but always soak the wall first as well, cob has huge suction propertys and will suck the moisture out of the plaster causing it to dry to quickly.
Allow the slurry to go green before plastering.

In a lot of ways cob is far superior to modern building materials , it is green, long lasting , strong , it will keep moisture levels within the building to a minimum , it has a good insulating value and how many Barrett homes do you think will still be around in 500 or more years? a third of people on the earth live in earth buildings.

Before doing any repair work on your building you should read up on traditional building repair and cob, especially the use of lime and why and how older buildings need to breath.

Why don't BG manufacture it then?
 
If you have the room to build a stud wall in front, build it - and line it with 3/4" marine ply to fit the [kitchen?] cupboards to it. Maybe need to allow some ventilation into this too:RpS_thumbup:
