How do you fix the gap in laminate flooring?

The room is on a concrete slab with radiant heating but I live a block from the beach and I think the change in the weather ( snow cold in winter, hot and mid summer) may have caused it. It is so-called laminate wood. Any ideas, please ?

    If your wearing rubber heeled shoes use the heel of the shoe to push it back into place. May want to squeeze some wood glue into the joint. Wipe off the excess.

    I agree with William! Based on my experience with our laminate flooring which is floating, it does expand and contract a bit with humidity, etc. Some of our floors are glued, i.e. the planks were attached to each other when the floors were installed, and the others are a different type of floor, which is simply floating over the underlayment. The floating ones get these periodic gaps and they do just slide back against each other; personal preference whether it is annoying enough to glue the ends together.

      Thank you! It is a floating floor, but winter or summer, it hasn't changed. At least it will be easier to pull out if I have to.

    I had this happen to me after a small leak was discovered. What I did was to get some Teak coloured Wood Filler and fill it. After a week I went over the Wood filler with Varnish I already was using on another Job. But for a quick fix Varnish, you could use Nail Varnish - Clear........

  • Honestly I have never heard of radiant heating under laminate flooring. Screams fire hazard to me, but there is a chance I could be wrong. My best guess is that is what is causing the gap, and might happen to other boards. Take out the baseboard to start removing boards till you get to that location. Tap back into place, replace boards and add in a shim before replacing baseboard so it doesn't shift again.

    Yes laminate floor will move in hot and cold weather....that is why there needs to be a gap around the perimeter. I have never heard of radiant heat under laminate flooring either but good luck. Does this space expand when the radiant heat is on? Heat may be causing it.

    Radiant heat whether its pipes embedded in the concrete with hot water running through them or electric mat on the surface of the concrete would not have any affect on the flooring. The underlayment protects the flooring. The hot water or electric mat heat the concrete slab which keeps the floor warm and about three feet of air space above the floor. Usually thermostatically controlled.

    there's a tool for that. it's shaped is about 12 inches long with a tab on each end facing opposite directions so you can 'hook' one end over the end of the plank and tap the other end with a hammer to make it slide within the groove.

    I had gaps in my floor like this. I tried the tool hal mentioned, my shoes and a suction cup tool. None of them worked on my floor. I bought the floor gap fixer and it closed all of my gaps. Some of them did come back. I closed those ones a second time and added glue to the joint. So far so good.
