I laid 12x24 tile 2 weeks ago, outdoors, and directly to concrete. I thought 3 days of drying would be sufficient, but it rained after the third day. Since then we have had 2-3 days of sun, and then 1-2 days of rain, consistently since then. Two weeks later a lot of the tiles are “squishy and spongy” when you press on them. With enough warm days and no rain, will the adhesive eventually harden, or am I out of luck, and need to pull everything up?
