Does a flat concrete floor need treating with latex levelling compound?

Sounds like they're taking the easy option, more money, less work.

 

Common practice to use Latex commercially in this situation. The latex will all any imperfections to be filled which is what you want as vinyl will follow every contour and dip and high point.

 

Buy yourself a decent scraper, a long handle floor scrapper, I used the one below for removing adesive from a floor, very good.

You'll need to skim with a levelling compound,regardless how it comes off,but you will need to prime floor before using levelling.

 

It would be quicker to self level the area, and it would get rid of any imperfections.

 

Try using a spade as a scraper.

i don't see how you are going to save money!

Once you spend all your hard graft time scraping it all out they will prob want to latex it anyhow.

They will have an industrial type scraper if there pros, which will get it done in half hour.

I have tried scraping after the glue with carpets and it took ages. Not worth the ball ache. Tried water on it, all sorts, if it's anything like that.

If I had to do it again I would use a multi tool maybe.

My personal view is let them crack on.

I'm not a flooring specialist but seen this latex method used many times with good results

Only my opinion good luck.

 

Plinths shouldn't be fitted tight so should have room to go up if need. The most ten mill

 

If the existing floor was good enough for the existing vinyl, then when cleaned up will be good enough for the new vinyl, if they are looking to over come existing glue etc with SLC, then there's a good chance the SLC will not stick to the glue etc and be more of a problem than cure.

 

Well, they are saving you money. You really don't want to pay a builder to be on his hands and knees for days scraping the floor. But of course, that's something you could do yourself, so yes, why not?

 

How big an area are we talking about?

 

I presumed a floor specialist was doing it not a builder.

If you are scraping that glue off you will take off some concrete here and there causing dips etc. I have done it myself, so you will have to fill level those areas somehow anyway.

The way they do this is by using latex substance, they will have a machine that will take glue off in prob half hour.

If it's anything like the carpet glue expect to be there for awhile.

If they are charging you a full day for this then yes do it yourself. ask them how much they are charging you.
