I am trying to remove a carpet from a concrete floor, and then will be having a wooden floor professionally layed onto the concrete floor. Only problem is that every square inch of the carpet was glued (with what appears to be superglue !!!!!) to the concrete. I have had moderate success with cutting sections and pulling them up, although in 2 days I have done about 1/16 of the carpet. The problem is that some bits of the felt underlay are still sticking to the floor. So I have several questions about this:-
1. Is there an easier way to do this ? I have read through some of the old messages on the group and it appears solvents are not a good idea due to risk of killing myself and blowing the house apart. I have heard that heating the bits I want to remove may be a good idea to soften the glue, could this be done with a paint removal hot gun or will that be too hot and set fire to the carpet (I fear that this will be the case). Has anyone tried using a floor scraper to do something like this ?
2. In relation to the preparation of the floor prior to laying the wood. The company doing the floor laying are glueing solid wood to the concrete floor which they assure me they do quite often and is very successful, I know some companies don't like doing this, but it does seem 50/50 those that do and those that don't. So my question is, just how flat does the floor have to be. I have patches where the concrete screed was not finished very well and there are bumps. Some of these bumps may give rise to a level difference of 10mm in places. I was planning on using self levelling compound on the floor, but most say that they only give coverages of approx 5mm. Anyone got any ideas on this one ? Could the screed be ground down to flat or is it better to bring the floor up to the top of the bumps ?
Any help for this VERY gratefully received.
