Mapei Keracaulk U Unsanded Caulk (Frost) - 10.5-oz

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.

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!

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.

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.

Product container had a slice cut into it and didn’t see this until being used! Lost around one third of caulk through the slice

Perfect match.

Solid product, matched grout nicely.

Thank you just what I neededBathroom tile finished.
