Hi all,

I while ago I had the old lino tiles lifted in my kitchen, then had a contractor come in to sand the old floor and lay new lino, this was done about 6 months ago and looked great.

A month on I noticed a small brown stain on floor, I did not think to much of it until it did not disappear when I moped the floor. I then gave it more attention with a good scrub with soapy water and gif, nothing happened.

Now a couple more have appeared and I am starting to think it could almost be something from under the floor seaping through the new lino.

Does anybody know what this could be? I want to get it sorted if possible before the floor has more of them.

Did anyone put any marks on the floor with a felt pen or similar after it was sanded?

What type of timber floor is the lino laid over?

I wouldn't think so, the contractor did the sanding then cut and lay the lino all in the same day when I was at work

Looks like moisture coming through the gap between floor boards?

Were the floorboards sealed after sanding? Do you know the adhesive used, and was it compatible / recommended to be used with your vinyl? I would contact the vinyl company about it to see what they think.

Could anyone have left a cheap dog toy or something sitting on it? I have seen similar marks where plastic stuff has had things in it migrate over to flooring when it was left sitting there and got hot in the sun.

That was my thought seeing the 1st pic. I'd measure from one of the 2 marks that seem inline to the edges to see if they mark the middle of the floor by chance.

Just spoke with a flooring contractor (Dad), he took one look and said water coming from underneath, probably from an un-boarded wooden floor.

Only solution will be to get the contractor back and redo it properly. It will still be under warranty and it will get worse as time goes by.

They normally put a thin substrate underneath like tilers do to make it level , and to try and prevent what you are experiencing.

Depends on what the price of it was, though I'd expect them to inform you of what can happen without the extra layer of villaboard

The guy who did the floor was a pro, but it was a cash job, unfortunately we could not put thinline down as the extra 3mm would make the floor to high (hard to explain why).

I'm guessing it would need to be ripped up, but then what if thinline ain't an option? Is there a paint that would block the moisture and do what is needed?

The job was a cash job so no warranty, but he was a good sort so I would think we could reach a deal

I guess you could get it waterproofed, like they do for bathrooms on ply floors? There are paint sealants but I'm not sure if there's one to apply to timber vs concrete

Whether he paid taxes or not is irrelevant. He is still liable. Doing cash jobs puts the contractor at risk .

The job was not done properly and will get worse over time. If you have access to the subfloor I guess you could reduce the moisture coming through.

It sounds like the contractor told you how to do it properly but you decided not to due to cost/aesthetics and because you bargained a cash price where the contractor would illegally be paying no taxes you don't really have any fall back.

If the contractor was a good sort they should have refused to do the job because of the problems that you are seeing and they should be paying taxes

Is it possible to see under the floor. If there's that much moisture where is it coming from? Is there a leak.

I had a dishwasher leak that travelled under the vinyl. You can see where the thinline has expanded but there is no discolouring of the vinyl.
