Application Guide


Before application of this product, thoroughly clean the surface of the roof to ensure that it is completely free from dust, dirt, oils, surface flaking, poorly bonded or glossy paint, sealers, varnishes, salts or any other contaminants. Any damaged surfaces must be fully repaired prior to application. Please note: your surface must be completely dry before application of this product, it cannot be applied on wet or damp surfaces. 

Whilst a primer is typically unnecessary, highly porous/friable surfaces may require the use of a primer before coating with this product. We advise an inspection be carried out an adhesion test on any existing porous surface or substrate prior to application of the coating.


Surface Preparation with Geotextile Tape

All joints, seams, cracks, vents, etc must be bridged with Geo fabric, as per the instructions. All joints, e.g. of torch-on membrane, sheet metal, vertical and horizontal transitions, must be additionally reinforced with Geotextile at a 10-15 cm width.

Application of Geotextile Tape

Geotextile tape is embedded into the wet liquid rubber coating avoiding creasing. Adjacent lengths of the reinforcement must overlap by 75mm. Finish with one coat of liquid rubber waterproof coating to seal the tape. Apply Geotextile tape:

  • to all areas which can be bonded.
  • must be used on all upstands, curves, skylight bases and rainwater outlets.
  • must be used on all gutter expansion joints.
  • must be used on all repaired areas.



Do not apply below 2°C or in freezing conditions. Application temperature should ideally be between 5°C-25°C.

1. Ensure that the surface you're working with is completely dry before application.

2. Stir the product thoroughly before use, ensuring that it is uniform throughout. 

3. Begin applying the coating to your surface, using either a brush or a roller as you would a normal layer of paint.

4. One layer should be sufficient, but do inspect the final product before considering any further required coats.
