AlphaGuard BIO primer (Direct Coating).

Guidance for specification option:

The specific AlphaGuard BIO primer type is subject to adhesion tests and the proposed substrate material.

Standard AlphaGuard BIO primers:

• AlphaGuard BIO WB Primer:

• Primarily used to enhance the adhesive strength of AlphaGuard BIO coatings to bitumen and asphalt substrates.
• AlphaGuard WB Primer is hand-applied in a single coat with an application rate of 5-6 m²/L for smooth substrates and 1.7-2.5 m²/L for granular or absorbent substrates. Cure time is approximately 6-8 hours.

• AlphaGuard C-Prime:

• Primarily used to enhance the adhesive strength of AlphaGuard BIO coatings to masonry and green concrete substrates.
• AlphaGuard C-Prime is hand-applied in a single coat with an application rate of 2.5 m²/kg (15 m²/6 kg kit). A and B components should be mechanically mixed for a minimum of 2 minutes. Cure time is approximately 3-4 hours.

• AlphaGuard M-Prime:

• Primarily used to enhance the adhesive strength of AlphaGuard BIO coatings to metal substrates.
• AlphaGuard M-Prime is hand-applied in a single coat with an application rate of 6 m²/L. Cure time is approximately 15 minutes.

AlphaGuard BIO.

Guidance for specification option:

A fully reinforced, two-component, polyurethane liquid applied membrane with catalyst technology. AlphaGuard BIO has exceptional low odour properties and provides a robust waterproofing layer that can easily cope with normal levels of structural or thermal movement.

AlphaGuard BIO Basecoat is hand-applied in two separate coats with AlphaGuard 225g Reinforcement installed between each coat. AlphaGuard BIO Basecoat should be applied at a rate 0.8 kg/m² achieving a final coverage of 1.6 kg/m². To complete the membrane system, AlphaGuard BIO Top Coat is hand-applied in a single coat at 1.2 kg/m².

AlphaGuard 225g Reinforcement.

Guidance for specification option:

A strong, chopped strand matting, glass fibre reinforcement that provides enhanced strength to liquid applied membrane systems.

AlphaGuard 225g Reinforcement is applied between separate coats of AlphaGuard BIO Basecoat. AlphaGuard 225g Reinforcement should be carefully embedded into the base coat, lapped by minimum of 50 mm, and laid flat without creases, air pockets or prominent fibres.

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.
