Application Description

Surface Preparation

Freshly Plastered surfaces must be allowed to cure completely. It is recommended to allow at least 12 weeks as the curing time for new masonry surfaces. Please ensure pH level between 7 & 9 before painting.
Ensure surface is thoroughly clean, dry and free from all loose dirt, chalk, grease, fungi, algae and flaking paint. This can be achieved by brushing with a wire/stiff coir brush, followed by water jetting if required.
If after thoroughly cleaning the surface, the surface still exhibits chalkiness, it should be coated with WS Sealer E1000 (recommended) or Exterior Sealer E900. For areas severely affected by algae or fungus application of Pre-Treatment coat is recommended.
Fill up all minor cracks and defects with cement and sand mixture in the ratio 1:3. Avoid application of putty or filling compound.
Weathershield Express should not be applied to the surfaces or substrates which are exposed to continuous seepage or dampness. For best adhesion performance, the moisture content in the wall should not exceed 10%
