1st tube material was ok, 2 days later after using 1/3 tube (with proper sealing the tube) the material was too dry to apply.Ordered a 2nd tube to complete the job & it was too day to apply when freshly opened. I do believe I was sent old stock both times. Both tube put out what I'd call silly putty material, not caulk.Very difficult to use in a caulk gun due to it's material dryness of both tubes.Going to attempt seller but not holding my breath - $40 wasted

I managed to check the date codes and the tube I received was only 2 months old. It color matched perfectly to the grout and the shower came out great!

The grout on the corner of my shower was cracking and disappearing. I purchased this product to seal the corner. It matched my grout perfectly and very easy to work with. I just did it a few days ago, so I don't know yet how long it will last. But my bathroom looks great.

Color doesn’t seem to match well at first, but from a distance it looks fine. No one will notice but me. Also when the Mapei Frost sanded grout gets wet, it gets a little darker, and the caulk matches even closer then.

If you're installing tile above a fiberglass or acrylic tub, don't use the grout where the tile meets the tub or corners. The tub will flex and the grout won't- pulling away from the tub. Corners may settle/shift. Use this caulk instead. It's flexible and will move with the tub/walls. It matches the grout perfectly.
