G120 Reinforcement Fleece

Radmat G120 Reinforcement Fleece is a reinforcement fleece for use with ParaFlex FD Liquid Applied Waterproofing Membrane.

For a comprehensive NBS J31 specification contact Radmat Building Products.

Embed reinforcement fleece into ParaFlex FD immediately after the first coat, ensuring a smooth application by carefully using a soft brush. Ensure each roll of Fleece overlaps the previous by at least 75mm. Installation to be according to guidelines and specifications supplied by Radmat Building Products Ltd.

ParaFlex-FV Mastic_featured

ParaFlex FV Mastic

ParaFlex FV Mastic is a one component fibre-reinforced MS-Polymer for the sealing of difficult and inaccessible roof details and connections. An additional mat reinforcement is not necessary.

ParaFlex FV Mastic is non-fading and UV-stable and therefore resistant to aging and also flexible at low temperatures. The material is one component and therefore more economical.

ParaFlex FV Mastic is used for repairs to all connections and penetrations on roofs and similar components that can only be reached with great difficulty and are made with fleece-reinforced liquid applied waterproofing membranes.


ParaFlex FV Mastic adheres to almost any surface and the connections are permanently waterproof. Exceptions are substrates made of PE, PP, TPO, FPO, silicone and Teflon.

The substrate must be clean and dry, free of oil and grease, and prepared with ParaFlex Cleaner.

ParaFlex FV Mastic should be stored and applied at between +15°C to +25°C, and applied to a substrate that has a surface temperature of between +5°C to +35°C.

Fire resistance
Flammable material class B2.

Resistance to spreading fire and reading heat to DIN 4102-1 and EN 1187.


ParaFlex Topsiegel

ParaFlex Topsiegel is used to enhance the appearance and modify the colour of ParaFlex sealants used on flat roofs. ParaFlex Topsiegel also removes the residual tack which forms on surfaces during the ParaFlex Topsiegel curing process.

ParaFlex Topsiegel is based on a polyurethane prepolymer and is resistant to dilute acids, alkaline solutions and all weathering influences. It also provides adequate protection against alkalinity (if concrete is also laid over the coating).

Seals improved by ParaFlex Topsiegel remain clean and are easily cleaned if necessary. In the case of light colour shades, surface heating through reflection is minimised.

ParaFlex Topsiegel is UV-stabilised and therefore resistant to ageing, resistant to spreading fire and radiant heat.

ParaFlex Topsiegel is a single-component product and hardens with exposure to air. The material may be used straight from the container and is therefore economical to use even on small areas.

Rainproof after approx. 30 min. Walkable after approx. 5 hrs and able to take all loads after 7 days. With special paints depends on amount of crosslinking agent added (10 – 30 g/kg).


ParaFlex Universal Primer


ParaFlex Universal Primer is a multi-purpose primer for use with ParaFlex FD, Liquid Applied Waterproofing Membrane. Consisting of a 1-component Polyurethane pre-polymer elastomer with aromatic + IPDA cross linking agents ParaFlex Universal Primer can be used on virtually any substrate, and offers adequate protection against alkalinity.

ParaFlex Universal Primer hardens with exposure to air making it particularly economical to use. The addition of cross linking agent ensures rapid curing even at low temperatures.

Contains solvents.


Tests should generally be made on curing and adhesion to the substrate.

The surface to be primed must be dry, free from dust, grease or oil, and have good adhesion and load-bearing properties.

The primer should be applied as a sealed film with blanket coverage and in principle should be sprinkled with quartz sand of grain size 0.3 to 0.7 mm or 0.4 to 0.8 mm.

Curing time: ParaFlex FD can be applied after approx. 15 – 60 minutes (depending on temperature).

Roll of fleece for use with ParaFlex FD Liquid Applied Membrane

ParaFlex Fleece G165/G225

ParaFlex Polyester Fleece is a special polyester mesh fabric that helps regulate layer thickness of the ParaFlex FD Liquid Applied Waterproofing Membrane and improves the cured breaking strength.

The sewn-in polyester mesh provides good directional stability, ensuring no changes in length occur during application and cuts can be prepared with precision.

In addition to its excellent technical properties, ParaFlex polyester mesh fabric is quickly and completely impregnation capacity during use, enabling it to fit tightly at upstands and transitions.

Unroll into first layer of ParaFlex FD Liquid Applied Waterproofing Membrane on flat areas prior to application of 2nd coat.

Saturate prior to application on upstands.

Curing time: ParaFlex FD can be applied after approx. 15 – 60 minutes (depending on temperature).

ParaFlex FD

ParaFlex FD

ParaFlex FD is a UV stable, cold, Liquid Applied Waterproofing Membrane suitable for many roof types: flat, sloping roof and complex roof shapes such as cupolas and barrel roofs. ParaFlex FD is also used to waterproof vertical surfaces.

ParaFlex FD is also used for waterproofing 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.

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.

The material basis of ParaFlex FD is unsaturated polyester elastomer with a polyester fabric reinforcement that determines the breaking strength and elongation at break and provides for even layer thickness.

For a comprehensive NBS J31 specification contract Radmat Building Products

ParaFlex FD is a Liquid Applied Waterproofing Membrane that must be installed according to guidelines given by Radmat Building Products Ltd. Rolls of polyester reinforcement are overlapped by 50mm. All other component material overlaps are determined by application but should not be less than 100mm.
