What surfaces is this paint suitable for?

How should I clean my tools after using this paint?

Does this paint protect against pollution?

Yes, the durable film offers excellent resistance against dirt, grime, and protects against atmospheric pollution.

Do I need to prime the surface first?

New or porous surfaces may require a mist coat (thinned paint) or a dedicated primer for best results. Ensure existing surfaces are sound and clean.

Troubleshooting

Paint not adhering properly

Ensure the surface was properly prepared, clean, dry, and free from dust or contaminants. Porous surfaces may require priming or a mist coat.

Poor coverage or streaking

Ensure the paint was stirred thoroughly. Check that the spread rate was not exceeded and that the surface is not overly absorbent. Apply an even coat, avoiding over-spreading.

Paint washes off during light rain

Verify that at least 20 minutes have passed since application and that the temperature was at or above 2°C. Ensure the rain was not heavy or prolonged shortly after application.

Uneven sheen or finish

Apply paint evenly with consistent brush strokes or roller application. Avoid stopping and starting mid-section or painting in direct, harsh sunlight which can cause uneven drying.

Pros and Cons

Pros

  • Rapid rain resistance protects against sudden showers.
  • Excellent durability against dirt, grime, and pollution.
  • High spread rate leads to efficient use of paint.
  • Can be applied in cooler temperatures, extending usability.
  • Good opacity reduces the need for multiple coats.

Cons

  • Smooth finish may not be suitable for all aesthetic preferences on textured surfaces.
  • Requires a minimum temperature of 2°C for application.
  • Primarily for masonry surfaces; not suitable for all exterior materials.

Setup, Compatibility & Care

Preparation: Ensure the masonry surface is clean, dry, and free from any loose material, dust, or chalking. Any existing paint should be sound. Treat any algae or mould growth with a suitable fungicide. New or porous surfaces may require a mist coat (thinned paint) or a dedicated primer.

Application: This paint is suitable for application by brush or roller. Stir the paint thoroughly before use. Apply evenly, avoiding over-application. The paint can be applied when temperatures are 2°C and rising. Avoid painting in direct sunlight, in very humid conditions, or when rain is imminent within the 20-minute drying window.

Compatibility: Primarily designed for exterior masonry surfaces. Ensure compatibility with any previously painted surfaces. Do not use on floors or surfaces subject to prolonged immersion in water.

Care: Clean brushes and rollers immediately after use with water. The dried paint film can be cleaned with a damp cloth or sponge and mild detergent if necessary, but avoid abrasive cleaners.
