A good surface preparation and following the method statement / recommended system procedure of Ritver is an ideal recommendation for the application of Ritver Alkali Resistant Primer.

For Plaster, Masonry & Concrete :
Achieve a good and clean surface by removing all contaminants and loose particles by cleaning & drying. A laitance free surface should be achieved by good sweep blast or a wire brush. Water washing under pressure is recommended.
Apply the Ritver Alkali Resistant Primer and allow drying as per the data sheet and subject to one more coat for even coverage.

For old and painted surfaces:
In case of surfaces which are painted / or aged and if there is visible dusting, chalking or even friable ensure that all the loose material is removed by scrapping or metal brush. Apply a good coat of Ritver Fungicidal wash compound and allow drying. Follow this by a regular coat or two of Ritver Alkali Resistant Primer




Adequate ventilation is an ideal situation as it helps in drying and the good application itself. Avoid high humid conditions i..e., 95% when condensation is likely to interfere and also when the surface temperature is at least 3c above dew point.
One can add 5 to 10% of sweet water for ease of application depending on the suitability of application.

1. Brush: It is an ideal recommendation especially to avoid runs and sags due to excess material.
2. Roller: Apply an even coat spreading uniformly taking care to avoid runs
