Cold applied liquid membrane system for uninsulated flat roofs.
AlphaGuard PUMA is ideal for providing a durable, fast curing, waterproof coating to any new build or refurbishment flat roof.
AlphaGuard PUMA is a high-performance, two-component, polyurethane modified, methyl methacrylate liquid applied membrane that is primarily specified to waterproof flat roof systems. With an extremely fast catalyst activation, AlphaGuard PUMA cures in minutes ensuring fast application times and minimal disruption to follow-on trades. AlphaGuard PUMA can be applied in low temperatures, has exceptional elongation properties, and offers a robust long lasting surface finish.

System performance | 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. |

Horizontal work | 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:
• AlphaGuard PUMA Asphalt Primer:

Liquid-applied waterproofing | |
Type | AlphaGuard PUMA WPGuidance 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. |
Reinforcement | 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. |
Surface protection | 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. |
System accessories | TremDome.Guidance for specification option: A traditional domed style rooflight that includes a thermally broken insulated kerb with excellent natural light transmittance properties. TremDome rooflights come with a variety of ventilation accessories and can be operated manually or electronically. Design is subject to survey or client requirements. TremDrain.Guidance for specification option: Gravity drainage outlets that have an integral membrane flange for sealing flat roof membranes. TremDrain outlets are manufactured from aluminium, are suitable for all roof types and offer excellent flow rate. Type, size, and design is subject to survey or client requirements. TremClip.Guidance for specification option: Lightning protection systems are frequently installed to buildings to avoid damaging and costly lightning strikes. TremClip has a threaded securement base that includes a separate retaining clip to secure lightning conductor tape at predefined centres across the roof. TremFlash.Guidance for specification option: A1 non-combustible secondary cover flashing manufactured from soft and workable zinc alloy. Primarily used as lead substitute in flat roof details such as wall chases or abutment flashing. TremTrim.Guidance for specification option: TremTrim is a prefabricated GRP edge trim that is specifically designed for multiple flat roof waterproofing types. Compatible with various Tremco reinforced bitumen membrane and liquid applied membrane systems, TremTrim provides an effective termination of the specified waterproofing systems at the perimeter edge. Ilbruck SP510.Guidance for specification option: General purpose low modulus sealant that is silicone free and cures to form a tack free surface. TremSeal mastic can be used to enhance the waterproofing integrity of a wide variety of detailing situations. Manufacturer guidanceAs required. |
