Suitable for bitumen based substrates, asphalt and felt substrates

Preparation
– Ensure surfaces are clean, dry, and free from dirt, dust, oil, grease, loose coatings, and other contaminants.
– Remove organic growth and treat with Bond It Mould Stop before priming.
– Do not apply to damp or wet surfaces.

Application
– Apply only when temperatures are above +5°C.
– Stir thoroughly before use to fully disperse pigments and polymers.
– Apply one coat using a brush or roller at the recommended coverage rate.
– Allow to cure fully before overcoating (typically overnight; up to 48 hours in cold conditions).
– The cured coating forms a light blue film for easy coverage identification.
– Apply additional coats only after the previous coat has fully cured.
– Ensure all bituminous surfaces are completely covered before applying Seal It Liquid Membrane.
– Apply a minimum of 2 coats over bitumen substrates; seams and edges may require a third coat.
– For exposed joints and edges, Seal It Cracks and Edging Sealer can be used as an alternative.
– Test a small, discreet area (approx. 1m²) with Seal It Liquid Membrane before full application to check for any adverse reaction with the substrate.
– Any colour of Seal It Liquid Membrane or Easiseal Pro can be used once priming is complete; however, discolouration may occur if primer coverage is incomplete or over water-based bitumen coatings.
– Once cured, apply Seal It Liquid Membrane or Easiseal Pro in accordance with the product instructions.
– For enhanced durability over bitumen substrates, use Seal It Reinforcing Mat within the membrane coating.

Cleaning
– Clean brushes and rollers with soap and water before the material hardens.
