For best results, surfaces should be damp. To obtain the protective properties of Vetoproof CM740, the correct rates of the application must be observed. Use a short, stiff brush, preferably 120 - 200 mm width, and apply in two or three coats as required. Use the correct mixing ratio to obtain satisfactory consistency for spray or trowel applications. Spray application will likely be the best for exterior decorative finishes in hot climatic conditions. Use nozzle size 3 - 4 mm, and a pressure of 6 - 8 bars.
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 a primer coat of mixed Vetoproof CM740 and water slurry-like consistency. Apply Vetoproof CM740 over the primer whilst it is still wet. It is recommended that for general resurfacing, each coat should be 1mm thick. Areas subjected to light foot traffic should receive at least 2mm thickness of Vetoproof CM740, and an additional 2mm 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.
