6. LATICRETE Hydro BAN Sheet Membrane Sealing Tape 5" X 16'5"
This tape became popular because it promises a foolproof seal at joints where liquid membranes might struggle to hold. In my assessment, this reputation is well-earned as it provides a physical buffer against movement.
I suggest using this alongside your liquid membrane to reinforce corners. It acts like a safety belt for your waterproofing system, ensuring that high-stress areas stay dry.
It is highly regarded for preventing leaks at shower wall junctions.

7. Laticrete Cementitious Waterproofing Membrane 30 lb Bag Polymer Fortified
This product earns its rank because its cementitious base provides unmatched strength for heavy-duty tiling projects. It is essentially a bridge between traditional mortar and modern waterproofing.
I view this as the perfect choice for thick-bed applications. It lacks the flexibility of liquid polymers, so be sure it fits your specific substrate before you buy.
It is a preferred solution for heavy masonry substrates.
Contractors appreciate the durability it adds to the foundation of a tile job.
The bag format requires careful mixing to ensure the right consistency.

Choosing Between Them
If you are aiming for a professional-grade installation, I recommend the Laticrete Hydro Ban XP 5 Gallon. It is the most robust choice for those who need high-performance protection across large or demanding surfaces. For smaller repair jobs, the Hydro Barrier Plus 1 Gallon provides the necessary moisture protection without excessive waste.
Always check your substrate before selecting a membrane, as the cementitious options behave quite differently than the liquid polymers. My top pick, the Hydro Ban XP, excels because its self-curing chemistry provides an extra layer of security against movement. Ensure you allow for proper drying times to get the most out of your chosen product.
