Asbestos board?

[Dylan123]

had some work done removing a door a while ago, didn’t seem like AIB when I looked at it before. I sprayed well with PVA anyway to be safe.

Looking at that board, I thought it was some kind of old chipboard but just want a 2nd opinion on if that looks like a type of asbestos board? The AIB I’ve seen before hasn’t looked like this, what do you think

Fibre board maybe. Used after the war as cheap and available.
I'd say it likely to contain asbestos. Get it tested

Just bought a test.

Pretty worried as it’s been like this in our hall for a year, but did spray it good with PVA.

on if that looks like a type of asbestos board

Asbestos doesn't have any particular 'look' or appearance. It's impossible to determine if asbestos is present from a visual inspection.
Asbestos was used in a vast number of building materials, and can still be found in many older buildings.

However asbestos contained in solid materials such as a board, tile or other hard substance has minimal risk unless you were cutting or drilling into it.
The risk is even smaller if it's been painted.

Thanks mate. So I didn’t touch it, the window guy ripped out the inner door way. So I wasn’t working on it but we were in the house the day it happened. I spotted the board a week later, thought it wasn’t asbestos and sprayed with PVA.

Are you saying that the fact it’s been there isn’t a disaster, it’s more if I was sanding/sawing it and getting a lungful of the debris?

I thought if it was damaged and had frayed edges it kind of gave off particles and was a massive issue - or maybe that’s more fluffy material like pipe lagging?

My step grandfather died of asbestosis at about 78 but he worked as an industrial builder for about 40 years after the war.

The highest risk are things like pipe lagging and other insulation which was sprayed on - any damage to that and it crumbles away to dust.
Woven or spun matting type insulation is also high risk, as the fibres are not enclosed.

Boards, corrugated sheets and other solid building products are very low risk as the asbestos fibres are held together by the cement or other materials used in them.
The problems occur when they are cut, drilled, sanded or similar as that is what separates the asbestos from the rest of the materials.

First sample the lab lost, finally got the next sample bag, and this time I had to cut a little piece out.

Having got a decent sample, it’s a chalky material between paper, never seen asbestos board like that before, this is why I thought it was plasterboard, no fibres just a hard chalky plaster core.

Test will work it out and will update.

Chalky crumbly non fibrous stuff sandwiched between paper is making me hopeful this is not a nasty!

Tested - negative
