Question: How do I prepare a concrete surface before applying Sika waterproofing?
Sika Construction Solutions
Answer: Preparation is the "secret" to 90% of a successful Sika application. Clean: The surface must be free of oil, dust, and loose particles. Dry/Damp: Check the technical data sheet for your specific Sika product, as some require the surface to be primed while others can be applied to slightly damp concrete. Repair: Fill deep holes or major cracks with a Sika repair mortar (SikaGrout or SikaMonotop) before applying your waterproofing layer.
