Application Directions
Substrate Preparation
The surface must be clean, and free from loose particles, including dust, laitance, grease, coatings, curing compounds, or any other foreign matter. The substrate must be prepared by way of degreasing, grinding or captive shot blasting to provide a surface profile. Apply suitable and approved joint caulking material such as Enviro Seal PUR polyurethane (allow to cure) prior to application of Enviro HP1200PW.
Priming
Contact Waterproofing Technologies for recommendations for appropriate primers prior to application of Enviro HP1200PW.
Mixing
Product is mixed at the 1:1 mix ratio (by volume) in heated plural component spray equipment. Both low and high pressure equipment can be used. Substrates Enviro HP1200PW is suitable over the following substrates:
• Concrete (cured for min. 28 days)
• Mild Steel • Aluminium (pre primed)
• Galvanised Steel NOTE: Do not apply membrane to any concrete that has received artificial curing compounds.
Estimating Data (Theoretical)
The Consumption of Enviro HP1200PW will depend upon substrate condition and type. As a guide: One 120 kg kit of Enviro HP 1200PW will cover approximately 60-80m² based on achieving an impermeable lining of minimum 1.5mm Dry Film Thickness (DFT).
Cure and Recoat Details
Curing rate of this product is dependent on ambient and surface temperatures. As the temperatures increase, the curing time decreases. Refer to product data sheet for further information.
