Laying a long length of engineered wood flooring

[altom]

Can someone please help / advise me on the way to lay tong and groove engineered flooring (189mm x 21mmthick). I have already laid fairly “successfully” a floating floor in a room measuring 6 x 4meters.

However my next project is to lay a floating floor for our very large through lounge dining room kitchen measuring approx 13 meters by 4 meters. It will have to be laid lengthways and hence the problem.

On the previous room I laid 3 widths to start off with and left overnight to cure. I ensured that those 3 widths were straight by pulling a cord from one end to another.

My problem now is the increased length. I am very worried that if I do not get the first 3 widths dead on straight on a distance of approx 13 meters I will be in trouble when I get to fitting the planks at the middle and towards the end.

Can someone advise me of the way forward please? (I am also aware that I am at the extreme limits of laying a floor without having expansion joints recommended after some 12 meters!.)

That 12 - or better 11 meters - is applicable in the width, not in the length of the room. Since your rooms are maximum 4 meters I can't see a problem there. As long as it is a rather open plan you could get away with not installing thresholds/dividers

As for keeping the rows straight over this length: take your time and if possible nail/screw blocks that'll hold the 3 rows in place into the underfloor so everything can settle overnight.

Many thanks "WoodYouLike" Now that is a good idea of placing / fixing some blocks down on the floor along the 13 meters. That would be a great guideline of course and I could therefore work against these. Why did I not think of that idea myself!!!?? Thanks again
