FAQs: Cement Waterproofing & Crack Repair Solutions

 

 

1. How to Apply Cement Waterproofing Slurry?

Q: What is the proper method to apply cement waterproofing slurry like SikaTop® Seal 107?
A:

  1. Surface Preparation: Clean the substrate thoroughly, removing dust, grease, or loose particles. Dampen the surface (no standing water).
  2. Mixing: Combine the powder and liquid components as per instructions. Mix until smooth.
  3. Application: Apply the slurry in two coats using a brush, roller, or spray. Ensure the second coat is perpendicular to the first for full coverage.
  4. Curing: Keep the surface moist for 24–48 hours to optimize strength.

 

 

2. What is the Best Mortar for Crack Repair?

Q: Which product is ideal for repairing cracks in concrete?
A: SikaLastic®-152 is the best choice for cracks up to 2mm wide. Its fiber-reinforced formula bridges cracks permanently and resists water ingress. For active leaks, use SikaMonoTop®-108 Water Plug for rapid sealing.

 

 

3. Can Cementitious Slurry Be Used on Damp Surfaces?

Q: Is surface drying required before applying waterproofing slurry?
A: Surfaces should be damp (not dripping wet) for products like SikaSeal®-250 Migrating. Excess water can dilute the slurry, reducing adhesion.

 

 

4. How Long Does Cement Waterproofing Last?

Q: What is the lifespan of Sika’s waterproofing solutions?
A: Properly applied, SikaTop® Seal 107 or Sikalite® SA-enhanced concrete can last 20+ years, even in harsh environments like basements or sewage systems.

 

 

5. Can I Use Crack-Bridging Mortar for Vertical Surfaces?

Q: Is SikaLastic®-152 suitable for walls or columns?
A: Yes! Its non-sag formulation adheres to vertical and overhead surfaces, making it ideal for bridges, retaining walls, and structural columns.
