Laminate on bowed and uneven floorboards

Hi, You should discuss this with the fitter prior to commencement of the project. There can be various options available including: self levelling compound, potential repair of floor boards, installation of sub floor e.g. plywood etc. Hope you find it useful.

Hi As you are aware a floor needs to be level in order to obtain a good quality floor installation .Due to the current floor being wooden boards you can firstly screw all board individually then the option of a sub floor would come into play should the previous method not be a option or remove and replace with 18mm ply if the condition of floor boards is poor .Best to establish the method with your contractor before installation .

Depending how bad the floorboards are you could ply the floor and screw the boards down screwing a screw every 250mm then lay your laminate on top if it still looks uneven you could pour self levelling compound to make it flat then lay on top of that

I wouldn’t recommend doing self leveling compound on top of wood floor boards or over plywood. I can tell from my experience will end up coming off due to woods movements when gets in contact with moisture. Just use plywood only to make it even or a very thick underlay.
