Possibly very experienced decorators could advice you on achieving a decent standard but 10+ years down the line I expect this problem to return again depending on may factors like moisture agitation trafficĪpologies for grammar just a dumb spread haha hope the advice helps you decide possiblyįrom what you mention on that reply then your lathes are holding up nicely and a reskim would be suitable but suction is always a killer so pva strong would be a must or a febmix sealer (poly grit) the a 2/3mm skim coat over the top Time will it put your project back ( been renovating my house nearly 2 years and not moved in yet btw □)Īnd are you living there because if you are dust dealing with the latter option can not be escaped it is really those factors you should consider Your decision is between cost and time and it comes down toįunding of materials rubbish removal etc. If you installing cables data etc again banging chases are a no no but a lot of agitation is a problem and your main concern if you want to save it The reboarding with a sound board of sound dampening is of importance then replastering. Or my person recommended option is getting dirty and wearing a mask gloves and a overall And and pulling all lathes de nailing re insulation in between with possibly a soundproof rockwool Which is the cheaper cleaner optionīut replastering I.e overskimming will only create a layer over the failing lathes only buying if any a short amount of time for it to be crack free and smooth, potentially even making the problem worse due to aggitation of the trowel pressing the lathe walls this loosening further, the same can be caused with aggressive rollering technique. Now if this flex is substantial me being a plasterer would advice either polyfill or fine casting or flexible fillers to smooth the cracks with a surface filler light sand and paint.

Rule of thumb if the walls flex quite substantially like 3/4mm it means the lathes nails are potentially failing a fix on the timber studs be it age related, moisture, traffic time gets us all. Hello long time plaster 15years plus jeez now I’m feeling old, having worked on listed buildings mainly in my career being from the uk lathe and plaster walls are a tricky one to deal with I tried looking it up but only thing I saw was really egregious cracks with depth but my Google foo is only as good as my search terms so I may be missing the lingo required to know what to look for.

(And yes I plan on testing for aspestos since it's in the right timeframe and some Rock-lathe apparently involved aspestos) or if they are shot and I should consider fully replacing them when I work on the house room by room. So I know I'm going to have to interact at some point with the walls it's just a question of if the walls are 'fine' and I can work with them and learn plastering to keep up the killer sound dampening of the walls. I plan on doing work in the long term on the house including redoing rooms and running Ethernet wall jacks and such.

I know nothing of plaster having lived in drywalled homes my whole life. The walls are smooth and only 2 rooms have any Real cracking (from an addition to the house causing a settling crack that I need to repair later) but I'm not sure if this is revealing a flaw in the plasterjob or if this is normal fair. The walls feel solid so I may be over worrying. Second picture is from a slightly different angle that shows how subtle this is. So as the title said bought a 1971 house with Rock-lathe walls at first glance everything looks fine but I realized all the walls that are still plastered have this subtle spiderwebbing to them that's evident when directional light is on them.
