Pre-wetting of the substrate
Thoroughly dampen the substrate surface with water using a brush, roller, or spray bottle. High porosity substrates will require more dampening than dense substrates. Do not apply the coating when the substrate is wet, but allow the water to soak in until the substrate is just visibly damp prior to proceeding. Any excess water should be removed using a sponge.
Mixing
Vetoproof S liquid concentrate should be shacked and completely poured from the plastic container into a suitably sized mixing container. Commence mixing with a propeller agitator attached to a slow speed drill (300-500 rpm). The powder component should be added gradually to the liquid to avoid lump formation and mixed for 2 to 4 minutes. Vetoproof S should be immediately used after mixing to avoid settlement of sand. Part mixing is not allowed. Mix whole kits. Do not mix more material than can be used within the pot life. Keep mixing Vetoproof S during the application.
Brush application
The most suitable type of brush is a soft bristled wallpaper paste brush (220mm wide and 50mm deep). Where larger areas are to be applied it is advisable to use a brush with a handle. Load the brush up well and spread the material to the required thickness. If the brush begins to drag during application, do not add water to the material, but dampen the surface again. Finish in one direction for a neat appearance.
Roller application
Application by roller has the benefit of speed over brush application, particularly on smooth substrates. A good quality medium hair roller is recommended. The roller should be well loaded for ease of application. A heavy roller pattern will be left on the substrate, therefore it is important to use a finishing tool to produce a smooth coating, with a uniform 0.75 mm wet film thickness.
Curing
Allow Vetoproof S to cure for at least 7 days prior to commissioning. At higher temperatures 30ºC cure for 4 days. At lower temperatures 12ºC cure for 10 days.
Cleaning
Immediately following application, clean all tools and equipment with clean water. Hardened material can be removed by mechanical means.
