Installation Tips for Sika Brushcoat WP

Proper installation is key to maximizing the effectiveness of Sika Brushcoat WP. Here’s how to apply it for optimal results:

Surface Preparation

1. Clean the surface thoroughly to remove any dirt, oil, grease, or loose particles.
2. Repair any cracks or damaged areas using a suitable Sika repair mortar.
3. Dampen the surface with clean water before applying the first coat, but avoid leaving standing water.

Mixing Instructions

1. Mix Part A (4.5 kg container) with Part B (18.0 kg bag) to form a total 22.5 kg set.
2. Stir the mixture until it achieves a smooth, lump-free consistency.

Application Process

1. Apply the first coat using a brush, roller, or trowel in an even, continuous layer.
2. Allow the first coat to dry before applying the second coat. Apply the second coat perpendicular to the first for complete coverage.
3. Protect the surface from direct sunlight, rain, and frost during the curing process to ensure the best results.

Coverage

Coverage is typically 1.5 to 2.0 kg/m² per coat, depending on the substrate’s porosity and the desired thickness.

Maintenance

• Regular inspections and touch-ups may be required for areas exposed to high moisture or wear.
• Reapply as needed to maintain long-term waterproofing performance.
