1. Dependant on environmental conditions. Values attained at 23 °C and 50% rel humidity. Times given are reduced with higher (and increased with lower) surrounding and work surface temperatures.

Surface Preparation

Ensure the substrate is sound, clean, dry and free of frost, dust and debris, and any material which would hinder adhesion.

Application Conditions

Apply only when atmospheric and substrate temperatures are greater than 5 °C. The surface of the substrate should be clean and dry and must be 3 °C above the dew point. If the surface is below or at dew point temperature then moisture can form at the surface and affect coating adhesion and curing.

For optimal ease of application, Seal-a-Leak™ should be above 12 °C.

Personal Protective Equipment (PPE) should be worn.

Application Method

Standard Repair:

Installation is best carried out when surface is dry, and free of frost. Sweep the area around the perforation with a brush to clear away any dust, loosely adhering particles, oil, grease, algae, mildew and fungal growth.

Application: Use a wide masking tape to mark out an area around the leak point allowing at least 75mm around the area needing repair. Pour out a sufficient quantity of the supplied EP1 Primer into the area in a snake pattern and then spread thinly with a brush. Allow the white primer to dry to a clear finish.

Cut the supplied reinforcing fabric to size with scissors.

Stir the Seal-a-Leak™ liquid before application. (Be careful not to create bubbles by over stirring).

Above the primed area, pour out a base coat of Seal-a-Leak™ liquid and spread using a brush or mini roller to achieve an even coverage. Embed the prepared fabric directly into the wet base coat making sure to work out any bubbles or wrinkles in the fabric using a brush. Apply a further generous coat of the Seal-a-Leak™ liquid onto the embedded fabric and spread evenly using the brush or roller, ensuring the fabric is fully saturated.

Full curing of the repair can take up to 4 hours (dependent upon weather conditions). The repair will be rainproof in less than 30 minutes.

Emergency Repair:

In emergencies when water is leaking into the building during wet weather, or where the puncture occurs under ponding water, making repairs can prove difficult to carry out.

In these situations Seal-a-Leak™ liquid may be poured directly above the puncture immediately plugging the leak.

Application: Stir the Seal-a-Leak™ liquid before application (be careful not to create bubbles by over stirring).

Pour the Seal-a-Leak™ liquid directly from the container onto the puncture and leave to cure. The Seal-a-Leak™ liquid will continue to cure even when under water. The Seal-a-Leak™ liquid will immediately plug the puncture, stopping further water from entering the building.

This type of repair should always be followed up with a more permanent repair.

Any remaining Seal-a-Leak™ liquid can be kept for future use following replacement of the container lid. coating cures to a form dry, transparent film finish. Depending upon atmospheric conditions, curing time can be 20 minutes (at 20 °C / 50 % RH).
