AlphaGuard PUMA Uninsulated Roof System (25 Year Warranty)

Guidance for specification option:

AlphaGuard PUMA systems possess a variety of independently assessed accreditations for performance such as British Board of Agrément, European Technical Assessment and a Broof(t4) fire rating under BS EN 13501-5:2016 fire classification of construction products and building elements.

AlphaGuard PUMA systems comply with the performance guidelines set out in relevant UK Building Regulations, BS 6229:2018 Flat roofs with continuously supported flexible waterproof coverings, and LRWA codes of practice.

AlphaGuard PUMA membranes also offer exceptional elongation and crack bridging properties that ensure long term durability.

AlphaGuard PUMA primer (Direct Coating).

Guidance for specification option:

A two component, methyl methacrylate-based adhesion promotor that has a fast and controlled catalyst activation. The specific AlphaGuard PUMA primer type is subject to adhesion tests and the proposed substrate material.

Standard AlphaGuard PUMA primers:

• AlphaGuard PUMA Concrete Primer:

• Primarily used to enhance the adhesive strength of AlphaGuard PUMA coatings to masonry, metal, and ceramic substrates.
• AlphaGuard PUMA Concrete Primer is hand-applied in a single coat with an application rate of 0.3–0.5 kg/m². Catalyst mixing is typically 2% by weight (20°C or below) but can be adjusted for lower ambient temperatures. Cure time is approximately 15-30 minutes.

• AlphaGuard PUMA Asphalt Primer:

• Primarily used to enhance the adhesive strength of AlphaGuard PUMA coatings to asphalt substrates.
• AlphaGuard PUMA Asphalt Primer is hand-applied in a single coat with an application rate of 0.3–0.5 kg/m². Catalyst mixing is typically 2% by weight (20°C or below) but can be adjusted for lower ambient temperatures. Cure time is approximately 15-30 minutes.

• AlphaGuard PUMA Primer H:

• Primarily used to enhance the adhesive strength of AlphaGuard PUMA coatings to green concrete substrates.
• AlphaGuard PUMA Primer H is hand-applied in a single coat with an application rate of 0.3–0.5 kg/m². Catalyst mixing is typically 2% by weight (20°C or below) but can be adjusted for lower ambient temperatures. Cure time is approximately 15-30 minutes.

AlphaGuard PUMA WP

Guidance for specification option:

A highly elastic, fully reinforced, polyurethane modified, methyl methacrylate liquid applied membrane that cures in minutes with an advanced catalyst activation. AlphaGuard PUMA WP has exceptional elongation and crack bridging properties offering a robust waterproofing layer that can easily cope with normal levels of structural or thermal movement.

AlphaGuard PUMA WP is hand-applied in two separate coats with AlphaGuard PUMA 165g Reinforcement Fabric installed between each coat. Each coat should be applied at a rate 1.4 kg/m² achieving a final waterproofing layer of 2.8 kg/m² (minimum 2.3 mm dry film thickness). Catalyst mixing is typically 2% by weight (20°C or below) but can be adjusted for lower ambient temperatures.

AlphaGuard PUMA 165g Reinforcement Fabric.

Guidance for specification option:

A strong, stitch bonded, polyester reinforcing fabric that provides enhanced strength to liquid applied membrane systems.

AlphaGuard PUMA 165g Reinforcement Fabric is applied between separate coats of AlphaGuard PUMA membrane. AlphaGuard PUMA 165g Reinforcement Fabric should be carefully embedded into the base coat, lapped by minimum of 50 mm, and laid flat without creases, air pockets or prominent fibres.

AlphaGuard PUMA Coloured Top Coat.

Guidance for specification option:

A polyurethane modified methyl methacrylate liquid coating that cures in minutes with an advanced catalyst activation. AlphaGuard PUMA Coloured Top Coat will provides a durable and long lasting finish.

AlphaGuard PUMA Coloured Top Coat is hand-applied with an application rate of 0.3-0.5 kg/m² in a single coat. Catalyst mixing is typically 2% by weight (20°C or below) but can be adjusted for lower ambient temperatures.
