Review on 🧊 Frost Mapei Keracaulk Sanded Caulking by Chris Parrott

When tiling a fiberglass or acrylic bathtub, do not grout where the tile touches the tub or in corners. The tub will flex and the grout will not separate from the tub. Corners can settle/move. Use this sealant instead. It is flexible and moves with the tub/walls. It goes perfectly with the grout.
