When it comes to bathroom and wet room installations, waterproofing is non-negotiable. Water damage behind tiles can lead to costly repairs, mould growth, and structural issues that compromise the integrity of your project. That's where tanking kits come in—they provide a comprehensive, tested approach to protecting your surfaces before tiling begins.
What Is a Tanking Kit?
A tanking kit is a complete waterproofing system designed to seal and protect areas prone to water exposure. These kits typically include a combination of primers, membranes, sealants, and reinforcing materials that work together to create a watertight barrier. Whether you're renovating a shower enclosure, installing a steam room, or creating a wet room floor, a tanking kit ensures water stays where it belongs—on the surface, not behind your tiles.
Why Tanking Matters in Tile Installation
Professional installers and serious DIY renovators know that proper tanking is the foundation of a long-lasting bathroom. Without it, water inevitably finds its way into substrate materials, leading to:
- Mould and mildew growth
- Tile adhesive failure and loose tiles
- Structural damage to walls and floors
- Costly remedial work down the line
Tanking kits eliminate these risks by creating a reliable moisture barrier that meets building regulations and industry standards.
What's Included in a Typical Tanking Kit?
Most tanking kits contain:
- Primer – Prepares the substrate and improves adhesion
- Waterproof membrane – The core protective layer, often liquid-applied or sheet-based
- Reinforcing tape or mesh – Strengthens seams and corners
- Sealant – Protects joints and penetrations
- Application tools – Rollers, brushes, or spreaders for consistent coverage
Some kits are designed for specific applications—floor tanking, wall tanking, or corner and edge protection—so choosing the right system for your project is essential.
Choosing the Right Tanking Kit for Your Project
Different installations have different requirements. A shower cubicle may need a different approach than a large wet room floor or a steam room. Consider:
- The area being protected (walls, floors, corners)
- The substrate material (plasterboard, concrete, timber)
- The level of water exposure (splash zones vs. constant immersion)
- Local building regulations and standards
Our tanking kits collection includes options for every scenario, from compact shower solutions to comprehensive wet room systems.
Installation Best Practices
For tanking to work effectively, proper installation is critical:
- Prepare the substrate thoroughly—clean, dry, and free of dust
- Apply primer evenly and allow it to cure fully
- Apply the waterproof membrane in thin, consistent coats
- Reinforce seams, corners, and penetrations with tape or mesh
- Allow adequate curing time before tiling
- Follow the manufacturer's instructions precisely
Rushing the tanking process or skipping steps can compromise the entire system, so patience and attention to detail pay dividends.
Tanking Kits vs. Individual Products
While you can purchase tanking components separately, a complete kit offers several advantages: all components are formulated to work together, you get the correct proportions and quantities, and the system has been tested as a whole. This reduces guesswork and increases the likelihood of a successful, long-lasting installation.
Invest in Quality Waterproofing
A tanking kit is one of the most important investments you'll make in a bathroom or wet room project. The cost of a quality system is minimal compared to the expense of repairing water damage or replacing failed installations. Whether you're a professional installer or a dedicated DIY renovator, choosing a reliable tanking kit protects your work and gives you confidence that your project will stand the test of time.
