Leak Lock 2-Pack: Waterproofing for Bathrooms, Kitchens and Balconies
Bathrooms, kitchen sinks and open balconies get wet every single day. Leak Lock 2-Pack is the two-component coating that keeps that water where it belongs.
Short answer: Turbolux Leak Lock is a two-component (2-pack) waterproof coating for interior wet areas. When its two parts are mixed, they cure into a tough, elastomeric, low-permeability film with strong adhesion, ideal for interior walls, bathrooms, kitchen sinks and balconies. It is eco-friendly and flexible, so it moves with the surface and resists the constant water exposure these areas face. Apply it under tiles or finishes to stop leaks before they spread to adjoining rooms.
What is Turbolux Leak Lock 2-Pack?
Leak Lock is a two-component waterproof coating. It comes as two parts that you mix together just before use; the two react and cure into a high-performance, seamless film that grips the surface and blocks water. That chemistry is what makes it tougher and more water-tight than a single-tin paint, and it is why 2-pack systems are the standard choice for the wettest parts of a home.
The dried coating is elastomeric, meaning it flexes rather than cracks, and it has low water permeability, so very little moisture can pass through it. On interior walls and floors that see water daily, that combination keeps leaks from creeping into the structure and into the rooms next door.
Where should you use Leak Lock?
Leak Lock is made for interior wet areas: interior walls, bathrooms, kitchen sinks and balconies. These are the places where water is present every day and where a hidden leak does the most damage, staining ceilings below, loosening tiles and feeding mould inside wall cavities.
It is typically used as a waterproofing layer on the substrate before tiling or finishing, so the protection sits under the visible surface. Bathroom floors and walls, the splash zone around a kitchen sink, and open balconies that catch the rain are all classic Leak Lock jobs.
Why does a two-component system matter?
Single-pack waterproofers are convenient, but for permanent wet zones the extra durability of a 2-pack pays off. Because the two components cure by reacting with each other rather than just drying, the finished film is denser, adheres more strongly and stands up better to constant water contact and light foot traffic. For a bathroom or balcony that will be wet for the life of the home, that reliability is worth it.

Leak Lock or Damp Shield: which do you need?
Both are waterproof coatings, but they are built for different zones. Leak Lock is an interior wet-area system for bathrooms, kitchen sinks and balconies, usually applied under tiles or finishes. Damp Shield is an exterior, fibre-reinforced elastomeric coating for terraces, chajjas and parapet walls, where it bridges cracks and takes the full monsoon. In many homes both are used: Damp Shield up top on the roof, Leak Lock inside the wet rooms. For rising damp on general walls, add Aqua Seal. See also our guide to anti-damp bathroom paint.
Frequently asked questions
Do I have to mix both parts?
Yes. Leak Lock is a two-component system. The two parts must be combined as directed so they cure into the tough, low-permeability film that makes it work. Mix only what you can apply in the working time.
Can I tile over Leak Lock?
It is designed as a waterproofing layer for wet areas and is typically applied to the substrate before tiling or finishing, so the protection sits underneath the visible surface.
Is it suitable for open balconies?
Yes. Balconies that catch rain are one of its intended uses, along with bathrooms, kitchen sinks and interior walls.
Can I use it on my terrace roof?
For roofs and exterior terraces, use Damp Shield, which is fibre-reinforced and built to bridge cracks outdoors. Leak Lock is for interior wet areas.
Is Leak Lock eco-friendly?
Yes, it is formulated as an eco-friendly waterproofing option, so you get strong protection with a more responsible product.
