        Underlayment - popping Sign In/Join 
        posted
        Good afternoon.

        I've attempted to remodel my bathroom on my own. I replaced a fairly large corner section of underlayment and installed all new vinyl tiles. I was in the middle of installing the vanity when I noticed a popping feeling of one of the vinyl tiles (just one). This tile is over the area where the corner of the new underlayment piece meets the old underlayment.

        So...I tore up the couple tiles from the wall to the problem tile and didn't see anything unusual. At this point, I used a few screws and a couple underlayment nails and that area is still popping. This only started happening when we moved the vanity into the final resting spot.

        Help!

        Thanks

        Dave

        Not sure if you are saying that the underlayment is popping up or if it's just the vinyl tile. Could be:

        1. A water leak causing subfloor to swell
        2. Underlayment installed to tightly with no room to expand.
        3. Same with vinly tiles - installed too close to the wall leaving no expansion room

        Thanks for the quick response Jaybee.

        To be clear...the underlayment is popping not the tiles.

        I replaced a water damaged section of the underlayment with the new underlayment. This is the beige color board in the picture. I used nails about every 5" and flooring compound between joints.

        One caveat...the new underlayment board was slight bowed but I thought all the nails would fix any possible issues.

        Strange things is that the popping is also occurring on the old underlayment board (brown) near the corner that the old and new meet.

        Thanks

        Dave

        Questions:

        What's the thickness of the beige and brown material? (I am assuming they are both the same)

        What is underneath this layer?

        Any chance that all it needs are some screws to pull everything down?

        Took my father-in-laws advise (and yours)and drove a 3" long screw into the old underlayment (around the corner where they met) and one in the new underlayment. No more popping. Hopefully it stays this way when I put the new toilet in place.

        Thanks
