【Home DIY Guide】Say goodbye to water leakage at home! An all-round sealing repair solution for the whole home
Summer in Hong Kong is always the season of typhoons and rain, with rainfall and humidity becoming the enemies of a comfortable home. For residents living in village houses or older buildings, or homes with balconies and floor-to-ceiling windows, water seepage around windows, balcony leaks, dripping water pipes, and mouldy, blackened bathroom sealant can cause plenty of trouble.
When facing these home water leakage problems, you do not need professional skills or major works. Simply master Selleys’ “all-round sealing repair solution” and use it together with Selleys sealant, Selleys mould-resistant bathroom glass sealant and Selleys Aqua Knead It, and you can easily deal with bathroom mould issues, home water leakage and more!
Humidity during the rainy season becomes a home “pain point”: how should you deal with water leakage at home?
Hong Kong’s climate conditions, together with the ageing of many residential buildings, have made home water leakage, seepage and mould growth everyday problems for many households.
When typhoon season arrives, strong winds and heavy rain can lash against your windows and seep indoors — at best wetting the floor, and at worst damaging walls and furniture. Bathrooms, meanwhile, are constantly humid, causing the silicone sealant around basins, bathtubs and walls to turn black and mouldy. This not only affects the look of your home, but may also breed bacteria. As for dripping pipes in the kitchen or toilet, over time they waste water, push up water bills, and may even cause nuisance to neighbours downstairs.

Many people assume these seemingly tricky water leakage problems can only be handled by professionals. In fact, many minor to moderate household leakage and mould issues can be fixed by yourself, as long as you use the right methods and products. For those who enjoy DIY, it not only saves repair costs, but also helps build up home maintenance know-how.

High-performance leak sealing: powerful repair with Selleys Knead It Aqua Epoxy Putty
When a pipe at home is dripping, or a water tank develops cracks, you need a more “heavy-duty” repair solution. Selleys Knead It Aqua Epoxy Putty is a hand-kneadable, strong, fast-drying 2-in-1 two-part epoxy putty. It offers powerful repairing, rebuilding and filling capabilities. It can be used for repairs in damp conditions or underwater, including salt water or fresh water, making it a go-to repair product for household leakage problems.
The clay-like texture of Selleys Knead It Aqua Epoxy Putty allows it to be kneaded into different shapes to suit various repair areas, so it will not drip during application. Once cured, it becomes as hard as stone, and can be sanded, drilled and painted. More importantly, it complies with the AS/NZS4020 standard for safe contact with drinking water, which is especially important when repairing potable water pipes. With Selleys Knead It Aqua Epoxy Putty, you can use it with greater peace of mind.
