How to replace floating floor boards?

Noyade

I'm too ashamed to explain how the water ingress remained undetected for so long - but you see the damage.

I was thinking of experimental surgery by removing the affected section with a multi-function tool and replacing new boards with glue to the concrete.

If the boards consent - what tool blade?

How to cut an acceptable straight line?

What glue?

Will the unaffected adjacent board flex too much, with the remaining underlay?

Has anyone pioneered this surgery before?

Feasible?

Any thoughts welcome! 👍

I saw this glue recently...

Hi @Noyade 

Are those click on laminate timber panelling? If they are, they should be clipped on to one another and the common way to repair them is to disassemble it. You could theoretically cut them out, but it would take precision cutting to modify a replacement panel as the clipping sides will have to be removed. 

It would not be necessary to glue the panel to the floor, but you will need to glue it to the flooring panels beside it so that it moves with the rest of the flooring, and it won't get left behind.

If you are still keen to cut it, I propose using a timber guide to prevent the multi tool blade from wavering too much. Unfortunately, some movement will occur as it is a free-floating tool. My best suggestion is to practice a few cuts on some offcut panels so that you can have a feel of how the blade will travel.

The wood and metal blade you have in your photo should work adequately.

If you need further assistance, please let us know.
