Small roll size: 5 in × 32.8 ft(12.7 cm × 10 m). Large roll size: 3.3 ft × 32.8 ft(1 m × 10 m). You are allowed to choose the membrane for different areas of the wall or floor.

This trowel is solid and non-deformed. The trowel blade features square-serrated to keep the mortar on the surface uneven, enhancing the adhesion between the membrane and the wall or floor. 【EFFORTLESS INSTALLATION】 - Install a shower bed kit is not difficult and won’t cost you a long time.
