• Eco friendly
• Excellent weather resistance.

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.

Application

• Before application of Trubuild walltect base 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 one coat of Trubuild walltect Basecoat horizontally without any dilution at the thickness of 120-130 micron for 45-50 sq ft per ltr per coat. Allow the coat to dry for min. 6-8 hours. After the base coat dries apply 1 to 2 coats of Trubuild Walltect Topcoat or any water based exterior acrylic decorative paint.
• Repainting- For repainting work, the performance of Trubuild Walltech Basecoat will depend upon the condition of the existing paint. If the existing paint film is flaking or has a weak bonding with the substrate then the subsequent coat of Trubuild Walltech Basecoat will face the adhesion problem. In case of repainting, application of Trubuild Primesure Primer is not necessary if the current surface is in sound condition and is stable, i.e., no flaking, peeling and loose particles on the surface.For a repainting work apply one coat of Trubuild Walltech Basecoat Coating without any dilution maintain the spreading rate of 45-50 sq ft per ltr per coat application to achieve about 120-130 microns DFT. After the base coat dries apply 1 to 2 coats of Trubuild Walltect Topcoat or any water based exterior acrylic decorative paint.

TECHNICAL DETAILS

Theoretical Coverage

• Trubuild Primesure Primer is 8-10 sqmtr/ltr/coat
• Trubuild walltect basecoat is 45-50 sq.ft /ltr/coat of to achieve the 120µ±10 DFT.

NOTE 1 - Coverage will depend upon the porosity & Undulation of the substrate.
