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 5 mm 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 1:80 to 1:100 should be maintained on the substrate to discharge run off water completely. Stagnant water due to undulation in the roof surface must be highlighted and repaired with polymer modified mortar. Ensure that all the penetration points, mechanical equipment, HVAC & solar panels are suitably placed on the upstand and rounded with angle filler and Resipro High Strength Hybrid Sealant. For china mosaic and other roofing tiles like ceramic, marble, clay, granite, etc. should be firmly bedded, primed and grouted with Trubuild Primesure Premium before application of top coat. Mix the Non Shrink Cementitious grout Trubuild Tile grout with Trubuild BWP 222 and make the desired consistency and fill the joints & cracks up to 5 mm. Fill the Tile joints with spatula or putty knife and buffing and cleaning should be done within 1-2 hrs for removal of any residue after work. Cracks up to 5 mm over china mosaic roof tiles surface must be cut and filled with Trubuild CFP 425

Application

• Before application of Trubuild Rooftect Advanced a self-Primer coat (50% 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.9-10 sq.mtr per ltr depending upon the substrate condition, allow it to dry minimum for 4-6 hrs. 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. After drying of Primer coat, apply 1st coat of Trubuild Rooftect Advanced horizontally without any dilution at the rate 2-2.2sqmtr/ltr/coat . Allow the first coat to dry for minimum 4-6 hours. During application of Trubuild Rooftect Advanced 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. Allow the system to curing for minimum 7-10 days air cure.

• Trubuild Rooftect Advanced as a primer (50% water dilution, by weight) is 9-10 m²/ltr/coat
• Trubuild Rooftect Advanced is 2-2.2sqmtr/ltr/coat. Min. two coat recommended.
• Trubuild Primesure Premium as primer without dilution coverage will be 120-150sqft/ltr/coat.”

NOTE 1 - Coverage will depend upon porosity and undulation of the substrate.

NOTE 2 - Comparative thermal performance of Trubuild Rooftect Top coat Advanced 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.
