- Water proofing – tough & elastic films provides excellent W/p
- Film thickness – provides higher dry film thickness of 1 to 1.25 mm in three coat application.
- Crack bridging – Bridges cracks upto 2 mm width.
- Application advantage – No need to remove existing BB coba, plaster, concrete surface.
- Strength - Higher tensile strength, tear resistance & bond strength with cementitious substrates.
- Resilience – forms highly elastic & resilient coating so helps to withstand the structural movements.
- Durability – Resistant to uv & weather conditions.
- Abrasion resistant – No additional protective coating is required for roof subjected to foot traffic.
- Ease of application – can by applied by brush & roller easily.
- Light weight – does not add extra weight over the roof.
- Non-toxic – eco friendly
- Breathability – it is Breathable.
- Building roofs / terraces – flat & slope.
- Over existing cementitious waterproofing treatments like brick-bat coba, concrete screeds, acrylic coatings, etc.
- Apply one coat of Dubond's Hydro Prime without any dilution at the rate of 10-12 m per litre. allow it to dry for 2-3 hours.
- 2 Apply the first coat of Dubond's Roof shield at the rate of 2 m per litre and allow it to dry before taking up the second and third coats,the rate of application being the same.
- The sequence of colours viz-a-viz, green or terracota grey can be decided depending on the desired top coat colour.
- In case only two colours are being used, ensure that the colour of the first and the third coat are the same. this would
- ensure correct consumption of material that will deliver a total Dft of 1 mm.
- Drying time between coats will be 6 to 8 hours.
- Ensure that the primer and the 3 coats of Dubond's Roof Shield totally achieve a minimum thickness of 1 mm Dft.
- allow the system to air cure for 7 days minimum.
