Method of Application

Substrate Quality

Substrate must be clean and dry. Relative humidity of the substrate should not exceed 85% and substrate temperature should be more than 3°C above the Dew Point to avoid condensation of moisture onto substrate prior to coating application. This coating can be applied to dry or green concrete, but ensure that there is no standing water during application.

Mixing

Chemscratch is available in a pre-weighed kit. Add Resin and Hardener in a bucket and mix for 1 minute with a helical paint mixer. Once the mixture has become homogeneous, add the aggregate powder and continue mixing for 2 minutes. Once the mixture is ready, it should be applied within the working pot life.

Application

Apply by notch trowel at the rate of 10-12 sqm/ kit. Coverage may vary depending on the floor profile.

Cleaning of Tools

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