Working on the never-ending basement brewery and we have this: old piping installation holes, leading into the kitchen above.

That grey subfloor is asbestos hardiboard. We are going to eventually redo the kitchen - just not this year (priorities, man!) what would be the best way to cover this from the basement side? gut says just gluepaint to encapsulate and a piece of ply to hide the holes, sound idea?

Edit: ok cos there seems to be repeated confusion: These are holes in the CEILING of a basement brewery leading to the asbestos floored kitchen ABOVE.

Ok. I see the misunderstanding.

The basement brewery is below the kitchen. We know for a fact the kitchen subfloor under the tiles is asbestos hardiboard, that's what's visible through the holes. Obviously we don't want it shedding in the beer, so we're approaching it from the brewery side.

    Ah, now it's all coming together...

    In that case spraying a bit of paint will help stick the fibres down in those spots, but if the chance of shedding there is a concern then you're probably better off covering the whole area to avoid anything working through the joints/cracks in the boards. I'd consider it a low risk even uncovered but I can understand wanting a bit more peace of mind for this.

    Something I'm now thinking could be an option for you would be to cover the ceiling with those foam/foil insulating panels (like this). They're light enough to stick to the ceiling with minimal fixings, would act as a decent barrier (particularly with the joints sealed with tape) and you get a bit of extra insulation as a side benefit.

    Yah, we're considering some panels - they're light and cheap enough at Bunnings, hubs is kinda in love with the dark wood look though. Trying to convince him he needs panels at least over the workspace...

    Your original solution of some glue and a piece of plywood seems like a fine solution, and honestly overkill imo. I'm open to being told I'm wrong, but the impression I get is that asbestos is completely safe as long as you don't fuck with it. It becomes a problem when you start ripping it out and the particles start floating around in the air. And I've never heard of anyone getting cancer from eating asbestos - just lung cancer from breathing it. If you are worried about it getting in the beer, you should be more worried about breathing it while you are down there.
