I caulked our guest bath this past weekend, where the tub and tile walls meet. I thought I used the right product, nonsanded, colored siliconized caulk by Mapei (Lowes) but now I am wondering if I used the right product at all. I've let it cure for 4 days, indicated 72 hours on the tube. I just used the tub today and not sure if cured correct or is finished curing. It almost feels really slick -- like it has not cured. It doesn't appear to be peeling off when I blot with a towel to soak up any extra water sitting where the 2 edges meet. Any thoughts or feedback would be much appreciated. Thank you.
