4. Sika Rooftop Waterproofing Process

Waterproofing the terrace with Sika is an effective and sustainable solution to protect the house from weather impacts. To ensure the construction process is highly effective, you need to follow the correct procedure:

Waterproofing the exposed rooftop surface

Step 1: Prepare the surface for construction

The surface needs to be cleaned of dirt, easily peeling residues, and ensure it is free of grease; repair any cracks and uneven depressions, ensuring the surface is dry before applying Sikalastic 590.

Step 2: Apply waterproofing with Sikalastic 590

Applying the primer: mix the product with clean water according to the manufacturer's recommended ratio and use a roller to apply a primer coat on the rooftop surface. You need to wait for the primer to dry for 2 - 3 hours before proceeding to the next step.

Applying the coating system: after the primer is completely dry, use a roller and directly apply pure Sikalastic 590 onto the surface, ensuring to roll evenly so that the coating is continuously spread. Then, wait for 3 - 4 hours for the applied coating to dry, and continue applying a similar coating at a right angle to the first layer.

Step 3: Maintenance and finishing

When completing the construction and rain is imminent, measures must be taken to shield the waterproofing layer from direct exposure to rainwater.

Do not walk directly on the surface of the waterproofing layer on the terrace immediately after construction; wait at least 24 hours for the waterproofing layer to meet the required standards.
