Shelf Life & Storage

Original sealed container of Vetoproof CM744 and has a shelf life of 12 months provided it is stored clear of ground in a dry shaded place below 35ºC.

Application Information
Instructions for use

Design Criteria
The coating should be applied in two coats to achieve a total dry film thickness of not less than 2 mm. Areas subjected to light foot traffic should receive minimum 2 mm thickness and an additional 2 mm coating should be applied to areas of moderate to heavy pedestrian conditions. To achieve the correct protective properties, Vetoproof CM744 must be applied on to the substrate at the coverage rates recommended.

Mixing
Vetoproof CM744 liquid concentrate should be 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 CM744 should be immediately used after mixing. Do not mix more material than can be used within the pot life. Keep mixing Vetoproof CM744 during the application.

Application
For best results, surfaces should be damp. In order to obtain the protective properties of Vetoproof CM744, it is important that the correct rates of application are observed. Use a short stiff brush preferably 120 - 200 mm width and apply in one or two coats as required. Spray or trowel applications should use the correct mixing ratio to obtain satisfactory consistency. In hot climatic conditions, it is likely that spray application will be the best for exterior decorative finishes. Nozzle size should be 3 - 4 mm and pressure of 6 - 8 bars should be used. The application of Vetoproof CM744 should not commence if the temperature of the substrate is below 5ºC. Application of Vetoproof CM744 on hot substrates, i.e. over 40ºC surface temperature will need the application of a primer coat of mixed Vetoproof CM744 and water in slurry like consistency and apply Vetoproof CM744 over the primer whilst it is still wet. It is recommended that for general resurfacing each coat should be 1 mm thick. Areas subjected to light foot traffic should receive at least 2 mm thickness of Vetoproof CM744 and an additional 2 mm should be applied if conditions are moderate to heavy pedestrian traffic. If in doubt about the condition of the substrate, consult Saveto technical department for any additional information.

Cleaning
Clean tools with water promptly before material hardens. Hardened material can be mechanically removed.

Surface Preparation

All surfaces should be dry and free from contamination such as oil, grease, loose particles, decayed matter, moss algal growth, laitence, and all traces of mould release oils and curing compounds. This is best achieved by lightly grit-blasting the surface. Where moss, algae or similar growths have occurred, treatment with a proprietary biocide should be carried out after the grit-blasting process. Spalled and deeply disintegrated concrete should be removed to sound concrete and repaired with a Saveto repair system. For further advice, consult the local Saveto office. It is essential that all surfaces to receive Vetoproof CM744 be pre-soaked with clean water prior to application of Vetoproof CM744.

Limitation

Do not apply the product at temperature less than +5ºC.

Additional Information
Health & Sefety

Vetoproof CM744 contains cement powders which, when mixed or become damp, release alkalies which can be harmful to the skin. During use, avoid inhalation of dust and contact with skin and eyes. Wear suitable protective clothing, gloves, eye protection and respiratory protective equipment. The use of barrier creams provide additional skin protection. In case of contact with skin, rinse with plenty of clean water, then cleanse with soap and water. In case of contact with eye, rinse immediately with plenty of clean water and seek medical advice. If swallowed, seek medical attention immediately – do not induce vomiting.

Vetoproof CM744 is non-flammable.
