Hi

 

We are putting in a new kitchen in our 1965 house.  It has rimu flooring throughout except for the kitchen and the laundry.  Since the lino was probably installed in the 80s I guessed it would almost definitely have asbestos in it (I cut a small square using standard precautions and it tested positive in the lab for chrysotile).  Originally the plan was to remove the lino and then sand + polish the rimu floor to match our lounge.

 

The asbestos seems non friable and appeared to lift off for the sample without any desquamation.

 

Has anyone had asbestos lino backing mat removed and what was the cost.  The kitchen is ~9 Sq meters and the lino area is ~6 Sq meters.  We are removing everything from the kitchen and completely re-doing it.  I would estimate it would probably cost about $3-5k to have it done professionally with an asbestos negative pressure tent, but I'm worried that there might be residual asbestos when the floor is sanded which could spread asbestos fibres everywhere when the floor sander goes in.

 

I also thought about covering up the lino with another either fake wood lino or wooden floor tiles or similar, however there will be a height discrepancy.

 

Q: Does anyone know what the rules are about sanding a wooden floor post asbestos removal? (I know that sanding machines are not allowed during the asbestos removal process), but not sure what the situation is afterwards.  Would they machine sand the floor with the tent still up?).

 

Q: Has anyone used a fake wooden vinyl that matched well with rimu flooring?

 

 

 

PS: This is in a home we are living in.

I can't comment on the asbestos flooring, but more on the wood;

 

 

 

Having had wood for some time now, how happy are you with the inevitable knife drops, pot drops, glass breakage and so on that will happen and damage the floor? scratch's are one thing, but a beautifully polished floor looks at it's best before you start using it, and then.... well....

 

 

 

I have original matai in other parts of the house and it is very hard wearing, but even it would struggle with breakages and sharp endpoints :-)

IME with uncovered and sanded rimu floors, if it wasn’t originally laid with ‘appearance quality’ in mind, it’s likely to have some gaps between the boards - I.e. not be alll closed-up. Gaps could also arise over 50 years of drying-out. This means that the refinished floor may not look like a new floor and an older look with gradual distressing in a kitchen might actually look quite good. I wouldn’t let the prospect of possible ageing wear and tear put me off polishing it.




Sometimes I just sit and think. Other times I just sit.

we don't tend to drop stuff very often :D

 

i like the rimu in the other parts of the house.

 

just not sure if it is safe to sand a rimu floor after asbestos is professionally removed.

Surely if you are paying for a professional company to remove the asbestos they will remove it all (or as close to all as possible) so there shouldn't be any residue remaining? If they go down the route of the tenting etc. could you come to an arrangement to have the kit up for another day or two and get the floors sanded while in protective gear?

 

We've got Rimu floors and did what you are doing a few years ago. Never thought to get an asbestos test though on the old lino...

The thing is there is no real perfect flooring material, all have their pros and cons. For example tiles are cold, and if you drop something heat it could crack the tile, or break what you drop. Vinyl looks like vinyl, even fake wood ones look fake. Cork tiles are good and not too cold to walk on, but some people don't like the look of those. Timber is good for flooring, but is like everything in a kitchen, you have to be careful. Kitchen units surfaces are also easily damaged.

Talk to the floor sander? if the tiles are removed and there is no residue, sanding will take the top few mm off depending on whats there, and when they are restained they look unbelieveably good.

You need to talk to an asbestos professional.

Often the glue had asbestos too so the asbestos removal company might have to give the floors a sand to get rid of it all, there will be glue in the cracks / knots / joins so might not be able to get it 100%.

They usually have some kind of sealing process post removal.

I strongly object to people covering this stuff up. I think it should be illegal. One day someone will want to drill a hole through that floor, by hiding it you are putting them at risk.

I liken it to burying old ammo in the garden.

We were in a similar situation to you, beautiful Rimu floors throughout the house then some hideous old lino in the kitchen.

 

We had it tested and both the tiles and the glue tested positive for asbestos. We used Southern Cross Asbestos removal to get rid of it, which cost a fortune (maybe ~6k, can't remember) and needed us to be out of the house for 3-4 days while they tented up, removed, tested air etc.

 

Afterwards there was still black marks around the nails which is possibly only tainting from the nails but given that it could be tiny traces of asbestos glue, we decided not to sand it (and risk releasing asbestos fibres into the air).

 

We thought about laminated floors however the wood looked ok even without sanding so we polyurethaned the floor anyway and it looks ok but 'has character' rather than looks pristine.

We don't have lino tiles, we just have regular lino / vinyl.



I think most people are completely ignorant as to how common asbestos is in our homes. If you have any lino that was laid between 1960 and 1990 then it almost certainly will contain some asbetos. Most people just rip it out without checking, and there is no way you can tell without sending it to a lab. The flooring people said they'd rip it out for me for about $200 but i told them not to as it might contain asbestos..

Just spoke to the old man who was been laying and polishing floors for 40 years.  He said once the Asbestos has been removed there should be no problem sanding it.  He has done jobs like this a number of times.

And to remove the Asbestos you should be banking on around $100 per square meter.  More for very small jobs.
