• How To Use
• Surface Preparation
• Surfaces must be prepared thoroughly before commencing. Surfaces are to be sound, stable, dry and clean, free of loose foreign matter including any surface residues or existing coatings. Buildings are to be constructed to relevant building standards and manufacturer’s recommendations are to be followed for all building materials used.
• Gripset Betta waterproofing system is made up of 3 stages:
• Priming
• Detailing
• Membranes
• Priming
• Priming is an important step in the application to optimize surface adhesion. Recommended primers for Pond Waterproofing Membrane
• Prep coat & Additive: Non tack primer coat for porous surfaces
• Super Primer: For non porous and smooth surfaces
• Damp Stop: For surfaces subjected to rising damp or residual moisture
• Mixing and Applying
• Before using Pond Waterproofing Membrane you will need:
• An electric stirrer, drill with paddle attachment
• Measuring jug or cup
• Clean water
• Then follow these steps:
• Calculate water required, pouring 2/3 of water needed into the empty pail supplied
• Measure powder required and slowly add to water. Start mixing with electric stirrer and paddle at a slow-medium speed. Mix until a lump free consistency is formed
• Add the remaining 1/3 of water and mix until a lump free slurry is formed
• Allow to settle for 1–2 minutes, lightly re-stir then use
• Forming a membrane Mixing water to be added:
• 750–900 mL/4 kg unit, forming approx. 3.5 Litres of wet membrane; 2.7–3.3 Litres/15 kg unit, forming approx. 12.5 Litres of wet membrane. Pot life once mixed is 45–60 minutes.
• Forming an adhesive Mixing water to be added: 600–720 mL/4 kg unit; 2.25–2.7 Litres/15 kg unit.
• Pot life once mixed is 20–40 minutes.
• Membrane Coverage
• For general applications, apply 2 coats at a total minimum coverage of 1.5 Litre/m² to form a 1.2 mm dried film. For immersed areas, apply 3 liberal coats at a total minimum coverage of 2 Litres/m² to form a 1.8 mm dried film. Coverage is dependent upon surface condition; greater coverage may be required on uneven and porous surfaces. Apply by roller (medium nap), stiff brush, trowel, spatula or spray unit. For adhesive applications, using a 6mm notch trowel, 1 m² will require 2.5 kg of powder.
