New kitchen fit laminate floor before or after?

please dont try to big yourself up, after asking when to lay laminate in a kitchen its fairly obvious your not as smart as you like to think you are! WE ALL try to plan for every eventuality but the truth is you CANT! that why manufacturers invented the phrase "under normal working conditions" i suggest you learn it.

 

as its a forum it seems to be a good place to discuss different methods of doing things, you fitted yours ontop of your laminate and assume you have done it the right way, maybe it is, maybe its not or maybe it does not make much difference either way, at the moment i can see benefits either way and by discussing it will eventually come to a conclusion as to which way i think is best regardless of what you think.
i appreciate you taking the time to put your method forward and would be grateful of any other input but my intellectual capacity is irrelevant to the discussion but as you seem to be wondering about it
im obviously not that clever same as the rest of you or we would not be in the building trade but i put 100% into what i do and make the best out of a bad situation.

but i do not want to big my self up on here as there is no gain to be had from it

what did you use under your laminate?

Could you not replace the 10mm underlay at that point with 10mm wood strip, that would transfer any load without compression.

 

so long as there's a decent amount or units on the run I wouldn't imagine there would be that much movement transfered to the end panel. You could try fixing a batten to the wall to help support the worktop and then either a bead of silicon, self adhesive foam rubber weatherseal or 18mm clear plinth strip to allow for any movement. Then explain to the customer that the top is well supported for general use, but not suitable for sitting on or 'paying the milkman'!!
Personaly, I'd fit it first then if there's a problem deal with it in one of the ways above.

 

There shouldnt be any compression as the laminate will be spreading the weight, therefore not causing a dip.
