ideas on how to remove under flooring?

Hello, we have recently bought a house and are preparing the floors for a wooden floor to be laid.
We are removing the old floor ourselves to save some money.

In the basement there was an office type carpet, which we removed but has left the foam layer welded to the cement floor, trying to get this foam stuff off is a nightmare, does anyone one have any tips or better ideas of how we can remove it?
We are using a scraper at the moment but its slow work and I was hoping someone on here would have an amazing tip that could get it done in an hour

Don't feed the kids until it's done.

Steam helps... sometimes.

Re: ideas on how to remove under flooring?

A scraper is all I've ever found for this - back-breaking work, and I can see why some people suggest leaving it down if at all possible. The absolute worst is where people have used foam-backed carpet, glued to a concrete / mastic floor, then left in place for thirty years. Grrrr.

Thankfully there's no carpets at all in our new place, so that's one less thing that will turn into a nightmare when we get round to it.

Re: ideas on how to remove under flooring?

This is a nasty ass problem. I have renovated a number of old homes (6) and some of them involved asbestos flooring tiles. The glue they used back in the day was serious stuff.



If I were you, I would jackhammer out all of that concrete and start over from the floor boards.


OR you can leave it and pour a self-leveller on it. In no circumstance would I continue to chip away at that adhesive. Have you tried a heat gun to melt it off? That may be an option.


Good luck. It is why they call it sweat equity.

Re: ideas on how to remove under flooring?

Heat Gun + old foam backing + old adhesive = toxic fumes.


It *probably* will get it up. Whether or not you will get up again afterwards is a different matter...


Have you shown this foam surface to the people laying the wooden floor? If its a clicklock type, they put a new foam layer down first usually. So it might not matter so much.


Regards

Re: ideas on how to remove under flooring?

thanks for the ideas,

We had considered a heat gun but now I've read your post "eairicbloodaxe" im maybe reconsidering it

I think we will have to do it the hard way...We have no money left in the pot to do anything very special - in order to afford the flooring we have to prep the floors ourselves .

There are only 2 rooms like this and after we have got rid of most of it we will be putting down our own electric underfloor heating (checked by an electrician ) in readiness for the wood floor.

Re: ideas on how to remove under flooring?

I have done this a few times, it's a ..... job. What you need to do is related to how the new floor will be laid.

You are aware that installing new electric underfloor heating is banned in some Cantons?

If the glue is well struck then wire brush the foam off being careful to not heat the glue so it melts and you should be ok. The problem is that sometimes a few places lift and trying to get a good edge that is not lifted is not possible. PM me if you want assistance and I can probably get you a deal on flooring if it's not a huge area.

Re: ideas on how to remove under flooring?

You can rent a machine from Coop Bau and Hobby to sand off the carpet backing. That's what we did and it worked just fine.

The company who came to install the new flooring just had to do a very light sanding.

Yes, this is what we were told when we wanted to put electric mats down. We had to go with piping instead which is far far more expensive.

I have done this several times. Heat the foam/glue and also heat the scraper. Wear a respirator and keep the place well ventilated. It has worked well for me, but it likely depends on what kind of stuff it is, you'll be heating up.

Re: ideas on how to remove under flooring?

Is this page saying electric under floor heating is a suitable replacement for electric heaters?

https://www.hev-zh.ch/wohnen/bauen/h...lektroheizung/

Before in these 2 rooms they had electric heater (which were taken away before we bought it leaving loads of wires just hanging from the wall )
