- Podium decks.
- Balconies with pedestrian access.

Description
ParaFlex FD is a three component unsaturated polyester resin waterproofing system reinforced with a polyester fleece reinforcement that determines the breaking strength and elongation at break and provides for even layer thickness.
Features and benefits:
- With the correct primers, ParaFlex FD adheres to almost any substrate and the attachments are made permanently waterproof.
- Combination with most bitumen and plastic roof sealing sheeting is also excellent.
- BBA certified.
- Resistant to roots in conformity with DIN EN 13948 (FLL guidelines).
- Resistant to spreading fire and radiant heat, as specified in DIN 4102, Part 7.
- Fireproof as defined by BS 476, Part 3, 2004.
- Durability: Exposed applications should achieve an initial life expectancy of at least 35 years. When fully protected and subject to normal service conditions in an inverted roof specification with an open covering (e.g. aggregate pavers), the system can provide an effective barrier to the transmission of liquid water and water vapour for the design life of the roof in which it is incorporated.
- Properties in relation to fire, buried applications: when used with one of the surface finishes detailed in Part iii of Table A5 of Appendix A of Approved Document B of the Building Regulations (England and Wales) or Technical Booklet E, Table 4.6, Part iv of the Building Regulations (Northern Ireland), would be deemed to be of designation AA.
- Resistance to wind uplift: The system will resist the effects of any likely wind suction acting on the roof.
- Resistance to foot traffic: The system can accept, without damage, the limited foot traffic and light concentrated loads associated with installation and maintenance operations. However, reasonable care should be taken to avoid puncture by sharp objects or concentrated loads. For areas of pedestrian access such as balconies and walkways, an anti-slip finish is applied.
- Curing time: With hardener and accelerator: Rainproof after 20 minutes. Walkable after 30 minutes.

Specification data - Liquid-applied cold roof covering systems
System performance | Waterproofing system, BBA certificate No. 09/4653, resistant to roots in conformity with DIN EN 13948 (FLL guidelines), resistant to spreading fire and radiant heat, as specified in DIN 4102, Part 7 and is fireproof as defined by BS 476, Part 3, 2004. |
Preparation | |
Horizontal work | Manufacturer's standard.Guidance for specification option: ParaFlex FD is a liquid applied waterproofing system that must be installed according to guidelines given by Radmat Building Products Ltd. Preparation instructions for horizontal work is likewise applicable for vertical, see specified guidance below. Manufacturer guidanceSuitable for many roof types including flat, sloping roof and complex roof shapes such as cupolas and barrel roofs. |
Skirtings and vertical work | Manufacturer's standard.Guidance for specification option: With the correct primers, ParaFlex FD adheres to almost any substrate and the attachments are made permanently waterproof. Substrates to which the system is to be applied must be properly prepared as adhesion to substrates will depend on the condition and cleanliness of the substrate. Substrates must be visibly dry, sound and free from loose materials or contamination (eg moss, algae). High pressure sand-blasting or water-jetting may be used to remove loose or flaking materials, but the substrate must be visibly dry before application of the system. Damaged areas of the substrate (e.g. broken fibre-cement sheets, blistered bitumen, roofing felt) must be removed, replaced or repaired. Deck surfaces should be free from sharp projections, such as protruding fixing bolts and concrete nibs. Gutters and outlets should be checked to ensure that they are, and remain, clear of all debris. The substrate should be primed with ParaFlex Primer prior to application of the system at a coverage rate of 300 g/m² to 500 g/m². Kiln-dried quartz sand, with a grain size of 0.3–0.8 mm, is broadcast into the wet primer. Ensure generous amounts of primer are applied to all vertical surfaces. Manufacturer guidanceSuitable for junctions and roof openings such as ventilation and pipe openings, supports and structures, lighting domes and chimneys, balcony doors and windows, and for a variety of applications which are very costly to seal by conventional sealing methods or cannot be sealed at all. |
Carrier membrane | |
Type | ParaFlex FD system can be overlaid on existing (roof) membrane in cold roof applications and can be combined with most bitumen and plastic roof sealing sheeting.Guidance for specification option: Note that some substrates may require a specialist primer e.g. steel and copper. Read instructions on the application sheets or consult with manufacturer for more details. |
Liquid-applied waterproofing | |
Type | Three component unsaturated polyester resin coating.Guidance for specification option: ParaFlex FD is mixed on site by adding the hardener to the resin in the correct proportion, and the accelerator in proportions relevant to the surface/ air temperature (see table in second image), and stirred in accordance with the mixing instructions. |
Reinforcement | Polyester (PES) fibre fleece reinforcement.Guidance for specification option: The first coat of ParaFlex FD is applied using a lambswool roller, and spread evenly prior to the installation of the polyester reinforcement, which is rolled into the wet resin and pressed free of trapped air using the roller. Each subsequent piece of reinforcement should have an overlap of at least 50 mm and sufficient resin should be beneath the reinforcement to maintain the system’s bond. A second layer of ParaFlex FD is applied and evenly spread. |
Surface protection | An anti-slip finish is applied, where necessary, for use on balconies, walkways or other areas of pedestrian access. |
System accessories | Not required.ParaFlex G165/G225 Reinforcement Fleece.Guidance for specification option: A polyester mesh fabric that helps regulate layer thickness of the ParaFlex FD and improves the cured breaking strength. ParaFlex G120 Reinforcement Fleece.Guidance for specification option: Reinforcing membrane for use with ReadySeal or ParaFlex FD cold liquid applied waterproofing systems. ParaFlex FD Drag Strip.Guidance for specification option: Debonding tape used to create a slip joint or expansion joint beneath ParaFlex FD. ParaFlex Universal Primer.Guidance for specification option: Multi-purpose primer for use with ParaFlex FD. |
