Application Information
Instructions for use

Mixing
5 to 7 liters of fresh clean water shall be poured 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 CM740 should be immediately used after mixing. Do not mix more material than can be used within the pot life. Keep mixing Vetoproof CM740 during the application.

Application
For best results, surfaces should be damp. In order to obtain the protective properties of Vetoproof CM740 it is important that the correct rates of application are observed. Use a short stiff brush preferably 120 - 200 mm width and apply in two or three 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 CM740 should not commence if the temperature of the substrate is below 5ºC. Application of Vetoproof CM740 on hot substrates, i.e. over 40ºC surface temperature will need the application of a primer coat of mixed Vetoproof CM740 and water in slurry like consistency and apply Vetoproof CM740 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 CM740 and an additional 2 mm should be applied if conditions are moderate to heavy pedestrian traffic. The membrane can be reinforced using a 2x2 or 4x4 acrylic coated glass fiber mesh of 140 - 180 gm/m2 immersed in between coats. 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 mold 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 CM740 be pre-soaked with clean water prior to application of Vetoproof CM740.

Limitation

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

For further information contact our technical department.

Additional Information
Health & Sefety

Vetoproof CM740 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 CM740 is non-flammable.
