Application
For best results, surface should be damp. In order to obtain the protective properties of Brushbond, 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 Brushbond should not commence if the temperature of the substrate is below 5°C. Application of Brushbond on hot substrates, i.e. over 40°C surface temperature will need the application of a primer coat of mixed Brushbond and water in slurry like consistency and supply Brushbond over the primer whilst it is still wet.
It is recommended that for general resurfacing each coat should be 1 mm thickness. Areas subjected to light foot traffic should receive at least 2 mm thickness of Brushbond 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, the local Fosroc office should be consulted.
