Surface preparation
- Newly plastered wall must be allowed to cure for minimum 3 months before painting.
- The surface must be free from dirt, dust and grease
- Remove all loose flaked coatings/particles or powder residue by thorough brushing and scrapping followed by water jetting, if required.
- Ensure removal of fungus and algae growth with suitable biocide treatment.
- Ensure that walls are completely dry before painting.
- Ensure that all water leakages and seepages are stopped completely before painting.
- Undulation to be rectified. Holes, dents and cracks are to be filled with exterior putty or sand mortar that is a mixture of White Cement & fine sand in the ratio of 1:3.
Priming
A base coat of Surfa Acrylic Exterior Cement Primer (WB) is mandatory to prevent failure of a paint film.
Application
- On well cured, dried and cleaned plastered walls, apply one coat of Surfa Acrylic Exterior Cement Primer (Water Based) diluting 1 litre of primer with 500ml of clean potable water and allow drying for 5-6 hrs.
- Apply two coats of Surfex Rain Shield-diluting 1 litre of paint with 400ml of clean potable water. Allow a minimum interval of 5-6 hrs between coats. On horizontal surfaces like tops of parapets and awnings, it is necessary to apply 3 coats.
- Deep shades like Sunrise, Ming Red, Flamingo, Dark Micado, Terracotta, etc. require additional coats.
Precautions
- Surfex Rain Shield is not suitable for painting on damp surfaces or where there is a continuous seepage of water.
- Do not apply the paint at temperatures below 10ºC or above 40ºC.

- Application of Exterior Wall Primer is compulsory for all surfaces. Not doing so, can lead to failure of the paint film.
- Do not dilute the paint. Over dilution of SURFEX Rain Shield may result in shade variation, poor hiding, poor bonding and flaking.
