Features and Construction

The spray combines multiple components to create an effective seal. Each ingredient serves a specific role in adhesion, flexibility, and moisture blocking.

Material and Build

The formulation includes calcium carbonate for bulk, polyurethane resin for flexibility and waterproofing, titanium dioxide for opacity, and bentonite to help swell and seal. The LPG propellant ensures easy, even spray application.

Each can contains 200ml of product, a compact size for storing in a toolkit or vehicle. The included syringe allows controlled coverage into narrow cracks and crevices, reducing waste.

Uses and Placement

This spray is designed for sealing leaks in common building materials such as roof tiles, concrete walls, and brickwork. It can be used both indoors and outdoors where a waterproof seal is needed.

Event or Professional Use

For tradespeople or maintenance teams, it offers a quick, portable repair option for temporary or permanent sealing of cracks in concrete floors or roof joints.

Everyday Home Use

Homeowners can use it to patch small roof leaks, seal gaps around windows or pipes, or stop damp patches on exterior walls.

Benefits and Buying Value

The key benefit is ease of use: no mixing, no brushes, just spray and syringe for precise placement. The low-pack size means you can buy only what you need for small jobs.

Reuse and Low Maintenance

The 200ml can is sufficient for multiple small repairs. After application, the seal sets without need for further treatment, saving time and effort.

Why Choose This Product

It combines a multi-ingredient waterproofing formula with the practicality of a syringe applicator, making it suited for pinpoint repairs where larger sealants would be messy or wasteful.
