Note: Sika® Brushcoat-WP must be applied in a minimum of 2 coats. 3 coats may be required in areas of extremely high infiltration.
- For overcoating with cementitious materials, allow the second coat to harden for at least 3 days prior to overcoating.
- For overcoating with non-cementitious materials, please refer to our Technical Service Department.
Uses
Sika® Brushcoat-WP will bridge pre-existing static hair-line cracks and is effective for waterproofing the following areas:
• Terraces and balconies.
• RC gutters.
• Bathroom floors and walls.
• Planter boxes.
Application
• Whilst the substrate is still damp from saturation, apply the first coat.
• Leave to harden for approximately 4–8 hours at temperatures above 20 °C before applying the second coat.
• For slurry consistency, apply with a hard plastic bristled brush or broom.
• For floor applications, to avoid risk of damage to the first coat, it is recommended that the second coat be applied after 24 hours.
• If the second coat is applied 12 hours or later, the first coat shall be slightly prewetted, preferably by using a fine spray.
• After the second coat has been applied, better finishing can be achieved by rubbing down with a soft, dry sponge.
• Sika® Brushcoat-WP can also be applied by trowel or by spraying. For more details, please refer to our Technical Service Department.
Curing Treatment
• Special curing methods are generally not required but some precautions should be taken for applications done directly under sunlight and windy conditions.
• It should be protected from direct rain for at least 4 hours.
Important Considerations
▪ Minimum ambient and substrate temperature is 8 °C.
▪ Never apply more than 4 kg/m² of Sika® BrushcoatWP in a single layer.
▪ Apply only to clean, sound substrates – surfaces should be well dampened but free of surface water and leaks.
▪ Sika® Brushcoat-WP is not a decorative treatment and may display signs of ‘blooming’ in damp weather conditions. This does not affect the quality of the coating in any way.
