### ⭐⭐⭐⭐ Good quality Sealant
*by A***L on 7 June 2025*

The sealant performed well in joining a flexible perforated 100mm drain to a soil pipe. One application with no leakage. Washes off hands or clothing immediately after use if spilt. Like others have noted the use by date was only 2 months after purchase.
