• Brick Bat coba
• Screeds
• Flat roof / Sloppy roofs and for miscellaneous surface contact Trubuild Technical service Team.

Note- For china mosaic and vitrified tile use Trubuild Primesure Premium.

• Excellent waterproofing system.
• Durable coating.
• Good bond strength
• Good weather resistance
• Excellent resilience to thermal stress.
• Reduce temperature up to 10°C
• Anti-carbonation properties
• Good Alkali resistance

Surface Preparation

• Remove the loose and unsound materials, oil, dirt, debris from the substrate. Remove all the previous waterproofing coatings if any by mechanical means to avoid failure of any subsequent upcoming waterproofing coatings. Fill all the existing cracks up to 5 mm by making “V” groove and then filling it with Trubuild CFP 425. for cracks larger than 5mm use Trubuild WPL 333/Trubuild BWP 222 for making Polymer modified mortar and then fill it. Then make angle fillet at wall and slab junction with help of Trubuild BWP 222 (10-12% of cement weight in mortar) and repair all the patches and joints with Trubuild Non-shrink grout HS and make surface becomes sound. Suitable slope of 1:100 to 1:150 should be maintained on the substrate to discharge run off water completely.

Application

• Before application of Trubuild Rooftect PRO a self-Primer coat (33% water dilution by weight) on the substrate should be applied. During self-priming it is to be ensured that the substrate to be in Saturated Dry Condition (SSD). The coverage of primer coat will be approx.8-10 sqmtr per ltr depending upon the substrate condition, allow it to dry minimum for 4-6hr. If the substrate is smooth or need to have more bond strength then, as a primer use Trubuild Primesure Premium can be recommended as expert solution with coverage of 120-150sqft/ ltr/coat without dilution by brush. (For more information contact Trubuild Technical services) After drying of Primer coat, apply 1st coat of Trubuild Rooftect PRO horizontally without any dilution at the rate 1.85-1.95 sqmtr per ltr per coat. Allow the first coat to dry for min. 4-6 hours. During application of Trubuild Rooftect PRO first coat over joints a 45 to 50 GSM Fibre Mesh can be recommended as a sandwiched layer between first and second coat to enhance Tensile properties of the coating. Then apply 2nd coat vertically without any dilution. Forced system coverage should be 0.93 sqmtr per ltr including priming. Allow the system to curing for minimum 7-10 days air cure.

Coverage

• Trubuild Rooftect PRO as a primer (33% water dilution, by weight) is 8-10 m²/ltr/coat
• Trubuild Rooftect PRO is 1.85-1.95sqmtr/ltr/coat. Min. two coat recommended.
• Forced coverage system Primer with Two coats of Trubuild Rooftect Pro is 0.93 sq.mtr/Ltr
• Trubuild Primesure Premium as primer without dilution coverage will be 120-150sqft/ltr/coat.”

NOTE 1 - Depends upon the porosity & Undulation of the substrate.

NOTE 2 - Comparative thermal performance of Trubuild Rooftect Pro on roofing. Temperature recorded from 1 pm to 3 pm of roof surface recorded with the aid of laser guided infrared non-contact thermometer. The degree of surface temperature reduction will vary depending on the condition of the existing surface, site location, roof pitch and weather factor.
