Step-by-Step Application Guide

• Surface Preparation: Substrate should be clean, free from dirt, dust, and all loosely adhering particles. Cement-based surfaces should be thoroughly saturated with water to achieve a surface saturated dry condition. All cracks larger than $1\text{mm}$ should be filled with cement-based concrete repair. Steel surfaces should be grit blasted, then cleaned by solvent and kept dry.

• Priming: Hydro Seal C1 does not require priming and can be directly applied onto concrete surfaces. For highly porous surfaces, a priming coat is recommended to seal pores and stabilize the surface. The primer coat can be produced on-site by diluting Hydro Seal C1 1:1 with water, applied at a rate of $5\text{ m}^2/\text{L}$ and allowed to dry.

• Mixing: Mix the contents of the 20 kg pail thoroughly prior to application to remove any sediment. Use a slow-speed drill and suitable paddle mixer to avoid air bubble formation.

• Application: Apply with a brush, roller, or airless spray in a minimum of 2 coats. Allow the 1st coat to dry completely before applying the 2nd coat cross-wise. Full strength is achieved after a 48-hour curing period.

• Corner Detailing: Apply a primer seal, followed by a base seal of Hydro Seal. Optionally embed a single reinforcement sheet of fiber mesh or geotextile ($120\text{g/m}^2$) for angle filling. Apply the final layer at $0.6\text{–}0.7\text{mm}$ thickness.

Frequently Asked Questions (FAQs)

• Q: Does Hydro Seal C1 require a separate primer?

  A: No, Hydro Seal C1 does not typically require priming and can be applied directly onto concrete. However, for highly porous surfaces, you can create an on-site primer by diluting Hydro Seal C1 1:1 with water.

• Q: How many coats are required for effective waterproofing?

  A: It must be applied in a minimum of 2 coats, with the second coat applied cross-wise after the first coat has dried completely.

• Q: What is the total coverage of a 20 kg pail (16 Liters)?

  A: One 16-liter pail covers approximately $80\text{ m}^2$ (~861 sq ft) per coat. For a standard 2-coat application, one pail will effectively cover roughly $40\text{ m}^2$ (~430 sq ft).

• Q: How long does it take to cure fully?

  A: The coating achieves its full structural and waterproofing strength after a curing period of 48 hours.
