Vetoproof S

All surfaces should be dry and free from contamination, such as oil, grease, loose particles, decayed matter, moss algal growth, laitance, and all traces of mold release oils and curing compounds. This is best achieved by lightly gritblasting the surface. Where moss, algae, or similar growths have occurred, please treat it with a proprietary biocide after the grit-blasting process. 

Remove spalled and deeply disintegrated concrete to sound concrete and repair it with a Saveto Repair System. Stop any running water with a suitable plugging mortar such as Vetoproof CR747. 

For further advice, consult the local Saveto office.

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 until the substrate is just visibly damp before proceeding. Remove any excess water by using a sponge.

Shake Vetoproof S liquid concentrate and completely pour it 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). Add the powder component gradually to the liquid to avoid lump formation and mix for 2-4 minutes. Immediately use Vetoproof S after mixing to avoid settlement of sand. Partial mixing is not allowed; mix the whole kit. Do not mix more material than can be used within the pot life. Keep mixing Vetoproof S during the application.

The most suitable brush is a soft-bristled wallpaper paste brush (220 mm wide and 50 mm 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 the application, do not add water to the material but dampen the surface again. Finish in one direction for a neat appearance.

Application by roller has the benefit of greater speed over brush application, particularly on smooth substrates. A good quality medium hair roller is recommended. Load the roller well for ease of application. A heavy roller will leave a pattern 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.

Allow the Vetoproof S to cure for at least 28 days before commissioning.

Immediately following the application, clean all tools and equipment with clean water. Hardened material can be removed by mechanical means.

Apply the first coat at a wet film thickness of 1 mm (approximate coverage per coat is 1.7 kg/m2 or 1 liter/m2). 

To ensure achieving the correct thickness, measure out an area (for example, 200 m2) then calculate how much material will be needed to cover this area. Monitor the coating thickness during application at regular intervals using a wet film gauge. During application, take care of filling the imperfections such as blowholes. If not, fill them while the coating is still in fluid status by using a dry sponge. If the coating dried before finding these imperfections, fill them using fresh material. 

The exact drying time will depend on surface temperature, relative humidity, and air movement. High temperatures and/or low humidity will reduce the drying time. This can vary from 1 to 16 hours. Leave the first coat to dry until firm and non-markable to the touch. There is no maximum time between coats; however, the surface may need cleaning with water before applying the second coat to remove potential contamination. 

Apply the second coat at a wet film thickness of 1 mm. Predampening of the surface is not necessary before applying the second coat. 

However, Vetoproof S is self-curing; it protects the freshly applied coating from rain and strong wind until it becomes firm to the touch.
