Surface Preparation

For old structure remove the loose unsound materials, oil, dirt, debris, existing paint, waterproof coatings or any type of other surface contaminations from the substrates. Treat any areas affected by Algae, moss or fungal growth with biocide wash solution. This is accomplished by pressure cleaning equipment with a minimum capability of 100-140 bar water pressure. For new construction remove all loose unsound materials, grease, oils etc must be removed completely by help of sand papers or pressurised water blasting. Fill all the existing cracks up to 5 mm by making “V” groove and then filling it with Trubuild crack filler paste (CFP 425). For cracks larger than 5mm use Polymer modified mortar making with Trubuild WPL 333/Trubuild BWP 222.



  • Before application of Trubuild Walltect Top coat, a primer coat with Trubuild primesure Primer on the substrate should be done. During application of primer, it is to be ensured that the surface should be in Saturated Dry Condition(SSD). For Filling the pores on the surface and providing good bonding to subsequent upcoming waterproofing layer use Trubuild Primesure primer in 2:1 (50% dilution with water) chemical to water ratio by weight, mix it well till we get homogeneous mixture using Low RPM paddle mixture. Before applying primer use air blower (Don’t use Hot air blower) to remove the dust present on surface, if any. The coverage of primer coat will be approx. 8-10sqmtr per ltr per coat, depending upon the substrate condition and apply all over the wall. After drying of Primer coat around 6-8 hours apply apply 1st coat of Trubuild walltect Top coat horizontally without any dilution. Allow the first coat to dry for min. 6-8 hours. then apply 2nd coat vertically without dilution The application coverage should be maintained 35-40 sq.ft. per ltr per two coats. Then allow coating to air cure for min. 7- 10 days for fully curing.
