Polytex

Recommended use

Polytex 10 a single component, elastomeric, acrylic waterproofing and protective coating to be used on:

• Concrete roofs
• Metal profile roofs.

Step by Step
Surface Preparation

Concrete Surface: Clean the surfaces which shall receive the coating of all dust, dirt, moss, oil and grease, loose particles, cement laitance and all other deleterious materials which will affect the adhesion of the coating with the substrate. Cracks and potholes shall be repaired with concrete repair mortar from the Polycrete range.

Metal surface: Clean the surface of all rust scales. This can be achieved by wire brushing or grit blasting.

Priming
Polytex 10 shall be diluted with 20% water and applied as primer coat on the concrete surface to seal the pores and stabilize the surface. The primer also functions as an adhesion promoter for the top coats. This primer coat can be applied by a brush, roller or airless spray and allowed to dry completely before the application of acrylic coating.

Application
Mix the contents of the drum prior to the application to remove any sediment. Polytex 10 can be applied by soft bristled brush, roller or an airless spray. When applying by airless spray then dilute the coating with approximately 5% water to reduce the viscosity of the coating. Apply the first coat of undiluted material at a coverage rate of 1L./m²/coat to get a Dry Film thickness of 0.50 mm. It is important to ensure that each coat has to be cured totally before applying the next coat. 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 strength and flexibility, embed a fibre mesh or a  65 g/m2 non woven geo-textile membrane whilst the first coat is still wet on all corner joints, fillets and pipe penetration joints. Allow the coating to cure fully for 72 hours to achieve its full properties.

Coverage
1L/m2/ coat for 0.5mm Dry Film Thickness. Two coats will give a combined thickness of 1.0mm thickness. (approx 10sqm per 20L drum)

Mixing Proportion
Ready to use

Colour and Quantity
Grey & White in 20L drum.
