Flooring – Plank vinyl flooring , the glue will not dry

vinylvinyl-flooring

I decided to replace the entire house with a glue down plank vinyl flooring. I followed the instructions and used the recommended glue to put it in place.

Two days after putting the floor down, when moving the appliances in I could see wet glue coming through the cracks. I cleaned it up and assumed I placed too much glue in that area. That was just the beginning of cleaning up glue. Months have gone by and here and there in the kitchen I would see wet glue come through the seams. Everyday that went by I was hoping it would finally dry.

Well, it’s been over a year and decided to peal a tile up only to see the concrete slab and the glue I put down was as wet as the day I put it down. I don’t know why the glue never dried in the kitchen and the rest of the house is fine.
I don’t have any water pipes that run through the slab, so it’s not a water leak.
The house was built in the mid-60s. The common floor type that was the glue down sheet vinyl with cut back black glue. I still had a hit and miss of this old glue still on the concrete but, it was mostly in another room where the new floor is fine.
I don’t know where to start to fix this problem.
I can pull up these tiles and clean the glue off the slab and reuse the tiles, but what glue will adhere to the concrete and the tile.
I’m looking for a solution to this mysterious problem.
Hope you can help me,

I'm going to bet that you used a "mastic" based tile setting adhesive, which would have been the wrong type for a kitchen. Mastic is an organic compound (from a Mastic tree) and will re-liquefy with moisture. not only is it bad for kitchens and bathrooms, but if the concrete was not sealed, moisture can come up from below and continually re-liquefy your mastic, even if it has dried. If it was mastic based, you may need to pull everything up, clean it off and reapply with a waterproof acrylic based tile compound.
