Caulking in expansion gap?

I have read that to help prevent water damage to floating laminate flooring in kitchens you should fill the 10mm expansion gap with 'flexible latex caulking' then bed the quad/beading into/ontop of that to cover it up.

I was going to use wet area 'no more gaps' . Product says 25% joint movement and 600% stretch...

Do you think that will do the job?
