+5°C min. / +30°C max.

Substrate moisture content

Dry or slightly damp - no ponding water.

Substrate pre-treatment

As primer;

  •  The product can be dilute 1:10 of liquid compound: 0.20- 0.25 kg/m2.
  •  Igasol BC can be used as a primer.

NOTE: The consumption quantities may vary depending on the application details and surface smoothness, absorption.

Drying time

As dependent on the ambient temperature, substrate temperature, relative humidity and the thickness of the coating applied approx. 3 days.

Waiting time to overcoating

Before a second coat previous coat must be dry.
Dependent on the ambient temperature, substrate temperature, relative humidity and the thickness of coating applied.
Protect the freshly applied coating for min. 72 hours from frost.
Consumption

Consumption

  • The product must be applied approx. 1.1 kg/m2 for 1 mm thickness. The product can be applied up to 6 mm of thickness for the effect of exposure to water.
  • The product must be applied 2.0 kg/m2 to adhere insulation boards.

NOTE: The consumption quantities may vary depending on the application details and surface smoothness, absorption.
Application steps

SUBSTRATE QUALITY

Substrate must be uniform, dry, free of dust, oil or grease and loose or friable particles. Surface defects such as blowholes, voids, honeycombing, etc. in the concrete must be repaired with suitable Sika mortars before coating.

SUBSTRATE PREPARATION

Repair damaged concrete substrates with Sika®repair mortars.
Rinse concrete surfaces with clean water.
Clean contaminated substrates by appropriate means including steam cleaning, high pressure water jetting, etc., to achieve a suitable substrate and surface quality as outlined above.
Prime porous substrates.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use.
