That should completely resolve the issue. The right choice of adhesive will be an important factor in a successful outcome. Maybe a specialist flooring company will have some answers?

Thanks for that.

I was thinking of fixing the Plywood direct to the original lino using a combination of adhesive and screws which will go through to the original floor.

I will have a handyman to help me lay the plywood but was wondering if I should completely remove the original Lino as not sure if the plywood will adhere to the lino but then again the screws should hold it ???

The lino people will only come after the new floor has been laid.

Hi Oorda, if it was me i`d definately remove the existing lino .it may be a bit of a task but you will be certain then that nothing will lift in the future .You will not want to do it a second time !! If you could go up to 12mm ply ,do so ,but bare in mind the extra weight .Any reputable TRADE quality timber adhesive will do your job well ie ; ,Sika. Holdfast(Gorilla) . Get a low odour ,solvent free ,or else you will be `floatin in the wind` . Good luck . Andy .

I've got a rockwood 2703 and parts of the floor have gone spongy. On investigation it appears that they have put down 2 of the floor boards and butted them together but where they join there is no support underneath like some frame work to attach them so when you walk over the join it sags. All I have to work out is how to join them together from the inside of the caravan rather than remove the covers under the caravan. I'm looking at putting 7mm ply (weight) down after taking up the lino that appears not to have been glued down in most places.
Any ideas how to join the 2 bits of flooring together? e.g. Some kind of strong tape.
I won't be doing anything for a couple of weeks but will let you know how I get on.

I wonder if you were to set a skill saw just shy of the depth of the ply, cut along the join that has no support and fill with Gorila Grip. That has a butt holding of 5000 kg. That surely would help.

Hi Warwick
Good Idea never thought of that. I think the problem will be the yanks use very thin wood maybe 4 mm thick and about 30 mm of polystyrene between them to keep weight down WOF weight so very light materials throughout. In saying that we have lived in it for 3 years full time and love the space it gives us. I'm thinking maybe some metal strapping and screwing it on either side of the join and maybe some gorilla glue for support.
I'll let you know how I get on.

This is what I've done to mine this morning. If it works out ok I'll put 7mm ply over the floor. I've used some gorilla glue under the plate also.
Hopefully this might be helpful
