Flexible, waterproof protection for balconies and walkways
Watco Balcony Coating is a hard wearing, flexible waterproofing coating ideal for balconies or external walkways where water ingress can cause problems. It fills hairline cracks and helps prevent the penetration of rainwater and moisture.
It provides a flexible and hard wearing surface. Because it is applied as a liquid, it can be used to protect around pipes, rainwater outlets and protrusions more effectively than sheet materials. We recommend that cracks or floor/wall joints are bridged with Watco Fibreglass Tape in conjunction with Watco Balcony Coating.

Surfaces must be cleaned of all grease, dust, cement laitance and other contaminants. Steel and iron surfaces must be rust free. Weak and spalled concrete must be cut back to a sound substrate and repaired using Watco Concrex. All surfaces must be thoroughly wetted to achieve saturation. A minimum air and surface temperature of 5°C is essential.
Place the powder into the bucket along with the small bag of pigment (if using the coloured version) and pour in approximately three quarters of the Watco Balcony Coating liquid. Mix using a slow speed drill and paddle mixer for approximately 3 minutes until a lump free, creamy consistency is achieved. Add the remaining liquid and mix thoroughly.
If appearance is critical, we recommend the Application of a small trial area first.
Application can be made by roller, trowel, or squeegee depending upon the finish required. The coating should be applied at approximately 1mm thick. If a second coat is required it can be applied as soon as the first is cured, normally 12-24 hours.
At 15-20°C, a floor treated with Watco Balcony Coating can take light traffic after approximately 16 hours and heavy traffic after 3 days. Full chemical curing is achieved over 7 days.
30 mins at 30°C, 1.5 hours at 20°C , 2 hours at 10°C.
