Areas of Application

Over existing building Flat/ Slope roof surface like

• Brick-Bat Coba finish surface
• Cement mortar screed
• China mosaic tile roofs.

Features

• Film thickness – Provides higher dry film thickness of 1 mm in three coat application
• Crack bridging – Bridges cracks up to 2 mm width
• Application advantage – No need to remove existing sound brickbat coba, plaster, concrete surface
• Suitability – Can be used for flat as well as sloping roofs
• 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 be applied by brush & roller easily
• Weight addition – Light in weight does not add extra weight over the roof
• Toxicity – It is non-toxic in nature

Surface Preparation

• Roof substrate must be pressure-washed with water with, a minimum working pressure of 1,400 psi is to be used to and/or remove all dirt, dust, chalking and waste products.
• When encountering roof substrates that have living organisms such as algae, mold or fungus, should be clean with 3:1 bleach solution or biowash shall be used to kill and remove these organisms during the roof cleaning.
• All new cement-sand, freshly laid screed / IPS surfaces should be allowed to age at least 12 weeks before application of topcoat surface coating.
• Ensure that the roof slope have a minimum of 1 in 80 or 100 is already provided.
• Check the soundness of the top screed, half round angel fillet / unsound plaster on vertical surface / joints surrounding pipe ducts of rainwater outlet, look for de-bonding signs by tapping with nylon hammer.
• Ensure there is a 1 water drain outlet of minimum 100 mm dia for 500 Sq. Ft floor area and gaps around pipe inserts should be sealed properly with polymer modified mortar.
• Stagnant water due to undulation in the roof surface should be marked and repaired with PMM.
• All joints / corners / penetration points, rainwater outlets, marble / tile strip joints should be grouted with PMM.
• Ensure that all penetration points, mechanical equipment, HVAC & solar panels are suitably placed on the up stands and rounded with angle fillet.
