Description
Waterproofing Hydro Seal 2kg
Create a durable waterproof barrier for ponds, fountains and water features with Hydro Seal.
Hydro Seal is a cement-based waterproofing solution designed to help seal porous surfaces and reduce water penetration in ponds, fountains and other water features.
Once applied to a properly prepared surface, Hydro Seal penetrates into the substrate and reacts with free lime to form a hard crystalline structure. This helps block pores within the surface and reduce the movement of water through the treated area.
The convenient 2kg pack is ideal for smaller waterproofing projects, repairs and water features where a larger quantity isn't required.

How Hydro Seal Works
Hydro Seal works within the surface rather than simply sitting on top of it.
As moisture is absorbed into the substrate, the waterproofing material penetrates the surface and reacts with free lime. This reaction forms a hard crystalline structure that helps fill pores and reduce water penetration.
Once properly applied and cured, the waterproofing becomes an integral part of the treated surface.

Hydro Seal is suitable for waterproofing applications such as:
-
Garden ponds

Coverage & Application
A 2kg bucket covers approximately 2m² for one coat.

| Product | Coverage – 1 Coat | Coverage – 2 Coats |
|---|---|---|
| 2kg Hydro Seal | Approx. 2m² | Approx. 1m² |
Please note: Actual coverage can vary depending on the porosity, texture and condition of the surface, as well as the thickness of application.
Mixing Requirements
Hydro Seal needs to be mixed with water and bonding liquid before application.
Good surface preparation is important for effective waterproofing. Before applying Hydro Seal:
-
Remove dirt, dust and contaminants
-
Remove any loose or unstable material
-
Properly repair suitable cracks or damaged areas
-
Make sure the substrate is correctly prepared for the waterproofing application
Always follow the recommended mixing, application and curing instructions for the best results.
