What plaster does this look like? Fitting for 1909? ACM (asbestos)?

    We are looking to fill in this hole that has been left exposed for over a period of ten years. It has been left in the state you have seen it, nobody has touched or fiddled with it since then but it is not extremely healthy looking.

    The house is Edwardian, built in 1909, and we are clueless as to it the house has been replastered since then. Does it look like plaster from this age of house? IF not, what is it?

    There are fears that this material could contain asbestos. It is extremely compact material, if that helps.

    If I am correct, if it is the original plaster there would be no worry. Underneath the lining paper (on previous areas of the house we have worked on) the plaster is smooth in texture.

    Just looking for opinions as the occupants of the house are panic ridden.

    What does this plaster look like to you? Does it fit the 1909 period? Or does it look extremely old? What does it contain upon seeing the images / videos? What is the plaster made up of? I am clueless myself!

    The fibres are from the torn paper and there doesn't seem to be any (noticeable) fibres in the plaster make up- behind the plaster is pure brick wall that the house was made with.

    There is little bits of white stuff. Is there any concern? Any opinion is welcomed. Trying to work out if this plaster is the original plaster or not / if it is common to find asbestos in residential plaster. This has been left exposed for over 10 years.



    If it is asbestos, hopefully it gives us enough time until growing organs in the lab is a possibility so we can replace our ones lol. It was made by rocking back and forth on a chair, making the hole overtime.

    I know it's incredibly hard to identify from an image if it is an ACM, but we are trying to cut out any potential risk factors / until we can afford testing or a surveyor. We would have been exposed for the past 10 years or so if it is an ACM, anything to bring peace of mind would be OK - even if it does turn out to be an ACM it would give us all time to prepare for any implications that can arise from exposure in the past.

    In short, what type of plaster does this look like?
    What is the likelihood that this house has been refurbished or replastered/how could we find out?
    Does wall plaster of this kind tend to contain asbestos?
    Upon first inspection, what materials does this plaster contain?
    Does it look like plaster from an Edwardian or very old house house (90 years old / longer)?
    What could those white bits be?

    Thanks

    Asbestos in plaster unlikely,usually horse hair added, but other animal hair possible.

    It would be a lime plaster,ash, clinker,sand & aggregate local to the area would added to the mix,as gypsum plaster didn't appear until around late 40's

    Cheers Kiab. For confirmation, the plaster in the images that you see is a mix of lime, ash and all the other things you mentioned?

    Likelihood is that this is the original plaster?

    +1 on what kiab says, make sure the right materials are used for repair as otherwise you'll be creating more problems, damp etc especially if non cavity construction

    Definitely. I'll have to sample this stuff anyway to work out what the actual blend of material is and then work from there to get the mix right.

    Do you reckon that this is safe to be left openly exposed then Longy / no danger? Would be safe to remove a piece? Just a bit paranoid to fiddle with it as my plastering knowledge is limited.

    Inhaling dust is never good for anyone but no real danger, if it's an external wall and no cavity insulation would def suggest you use sand and lime render as modern plaster is not suitable and you'll get issues with damp, doesn't have to be the exact same material as used previously as they just used what was available at the time locally

    It's a solid internal wall with no cavity insulation. Just plaster and brick.

    Any reputable brands that you could recommend when it comes to lime
    Plaster?

    :D Think I'd be more concerned about the 'Blue Woodchip'.:p

    If it's an internal wall and you've had no damp issues then you have more options in the materials you use, unless of course you want to keep with the tradition of the house, external non cavity walls need treating differently to prevent damp coming through. How sound is the rest of the wall? There's no point repairing a patch if the rest of the plaster has blown
