Frequently Asked Questions

Q: What surfaces does the self-adhesive silicone water stopper strip stick to?

A: The water retaining strip's self-adhesive backing bonds effectively to most clean, dry, smooth floor surfaces including tiles, vinyl, laminate, and sealed concrete. Make sure to thoroughly clean and dry the surface before installation for the strongest hold.

Q: Can the silicone shower dam barrier be cut to a custom length?

A: Yes! The flexible silicone strip can be trimmed with scissors or a utility knife to fit your exact space. It's also available in three lengths — 30 cm, 50 cm, and 100 cm — so you can choose the size closest to your needs to minimize cutting.

Q: Is this water stopper suitable for use in front of a washing machine?

A: Absolutely. The bendable silicone water barrier is ideal for placement in front of washing machines to contain any overflow or leaks. Its flexible design lets you shape it to fit around hoses or uneven surfaces with ease.

Q: How tall is the water retaining strip and will it be a trip hazard?

A: The strip measures just 12 mm in height, making it low-profile enough to minimize any trip risk while still being effective at containing water inside a shower or wet area. Its square profile ensures a stable, flat-footed footprint on the floor.
