Promac Rubber Duck Rain Guard is an acrylic waterproofing system comprising of a combined saturator, sealer and topcoat used in conjunction with a membrane (reinforcing polyester fabric). Prevents water ingress into roofs, parapet cappings, masonry walls and seals cracks / holes where leaks may occur. Can be used to treat difficult areas where conventional waterproofing is required.

• Excellent adhesion to suitably prepared surfaces

• Forms a watertight system with the membrane

• Low density system: does not add excess weight to structures

• May be overcoated with quality acrylic topcoats

• Non-toxic

• Tough and flexible

• Water clean-up

This product system will cover approximately 2.5 litre / m² for the full waterproofing application. Each coat within the waterproofing system has different spread rates, refer to APPLICATION heading. Spread rates vary depending on the type of substrate and surface porosity.

Primer coat:
Rubber Duck Nudek Primer & Sealer or Promac Bonding Liquid to the prepared surface. Ensure to apply a uniform wet film thickness 8-10m²/l per coat. Allow drying for 1-1:30 hours @ 23°C, then apply the first coat while tacky.

First coat and waterproofing coats: Apply two or more coats of Promac Rubber Duck Liquid Rubber to the prepared surface at a spreading rate of 1.5 - 2 litre / m² (to achieve best waterproofing coat). Allowing 4 hours drying time @ 23°C between coats. For best results, apply a uniform wet film thickness by spray or trowel to maximise water proofing properties.

Precautions - Roof Slopes:
Make sure that the slopes are such that they prevent water from ponding (Minimum slope of 2 - 4°). Make sure that the slopes are even along the roof.

Clean all tools (brushes and rollers) while wet with water after use.
