Notes:

• Davco K555 Slurry must be applied in minimum of 2 coats, including upturns up to 300 mm height.
• 3 coats may be required in areas of extremely high infiltration

Pour Part B into a clean mixing container.

Add Part A gradually while mixing continuously in circular motion using low-speed mechanical mixer until lump-free, plastic consistency is achieved.

Mix for 2–3 minutes to ensure proper dispersion of the components - no addition of water is allowed.

Whilst the substrate is still damp from saturation, apply the first coat. Leave to harden for approximately 4–8 hours at temperatures above 20 °C before applying the second coat.

As a slurry

Apply the mixed Davco K555 Slurry by hand using a hard plastic bristled brush or broom. Applied in the same direction. Apply the second coat of Davco K555 Slurry in a crosswise direction as soon as the first coat has hardened.

As a mortar

Davco K555 Slurry is applied by trowel (e.g. for a smooth surface finish). In this application Davco K555 Slurry must be mixed with a 10 % reduction of part A. The first coat is applied with a 1 mm notched trowel. Apply the second coat of Davco K555 Slurry with a flat trowel as soon as the first coat has hardened.

For pore / blowhole filling, tightly trowel into the pores / blowholes of the surface.

For floor applications, to avoid risk of damage and contamination to the first coat, it is recommended that the second coat be applied within 24 hours of the first coat. If the second coat is applied 12 hours or later, the first coat shall be slightly prewetted, preferably by using a fine spray. After the second coat has been applied, a better finish can be achieved by rubbing down with a soft, dry sponge.

Clean all tools and application equipment with water immediately after use. Hardened or cured material can only be mechanically removed.
