and organic basecoats.
Properties: Weather resistant, hydrophobic, water vapour
permeable, good mechanical resistance, easy to use.
Coverage: approx. 10m2
Substrate: Substrates must be sound, clean, dry, free from frost, dust efflorescence and notwater repellent.Existing mineral based coatings and paints must be sound and wellbonded to the substrate (confirm with pull off tests and/or cross cut tests acc. To Baumit guidelines).

Mixing: Baumit GranoporTop must be well and slowly mixed with an electric hand mixer before application.It may not be mixed with other paint materials. Where required a minimal amount of water (max. 1%) may be added to improve workability.
Application: The GranoporTop is applied with a stainless steel trowel or a fine spray machine and trowelled throughto the grain thickness to produce a full and even coat. The surface is then textured using a plastic float, moving in tight circular motions. It should be applied systematically and continuously in complete sections.
