Step by step

SURFACE PREPARATION

All the substrates must be dry and free of dust, dirt, moss, oil, grease and loose particles. Metal surfaces should be rust free. This can be achieved by wire brushing or grit blasting. Unsound surfaces are to be removed and repaired with a suitable repair mortar.

PRIMING

A primer coat is required to seal the pores and stabilize the surface. Polytex Super diluted with 20% clean water may be used as a primer coat. It will improve the bond strength of the coating. This can be applied by a brush, roller or spray. The primer coat should be allowed to dry completely before the application of Polytex Super. The drying time would be a minimum of 8 hours at 25°C.

APPLICATION

Stir the contents of the drum prior to the application to remove any sediments. Polytex Super can be applied by soft bristled brush or roller, but is prob- ably best applied using an air less spray. Apply the first coat of undiluted material at a coverage rate of 1L/m²/coat to get a Dry Film Thickness of 0.5 mm. It is important to ensure that each coat has to be cured totally before applying the next coat. Prior to the application of the second coat, a close visual inspection of the surface should be made for any pin holes or surface irregularities. The second coat should be applied at right angle to the first at the same coverage rate, to ensure a full unbroken coating to the substrate. For improved results a non woven geo-textile membrane can be reinforced in to the first coat while it is wet at expansion joint areas and on the fillets in all corners. This will give an added reinforcement to the coating. Allow the coating to cure fully (72 hours) after which it can be made trafficable.
