Aaargh, another problem with the job my eldest is expecting me to manage while he works away to earn the money to pay the craftsmen brought in as he discovers that diy takes effort.
He has decided on and bought tongue and grooved (not click together) engineered boards (quite thin, maybe 3mm?) for the whole ground floor, apart from the kitchen. So we have
- Dining room - a concrete floor with some small cracks, and someone is coming tomorrow to coat this in self-levelling compound.
Current thinking is that we need some sort of underlay and that the t&g should be glued (using pva?) to itself to result in a "floating" floor on top of the underlay. He is thinking of the fibreboard 5mm underlay throughout as sold by Wickes, but we are not sure how well this will work on the various surfaces. We think OK on the concrete and tiles, but the lounge floor does seem to have a bit of give.
Many of the doors are off, so the height should be no problem, and there was carpet + underlay in the lounge. There might be a bit of a height bodge needed where the floor meets the tiled internal porch.
The problem with all this is that we have been let down again by someone who was going to do the job. We have a painter who does general woodwork and this is stopping him fitting the new architrave and skirting boards. He might fit the floor and do the gluing but doesn't know whether smaller areas of flooring need the glue to set before moving on to the next "block".
Any guidance, as always, gratefully received.
