Proteus Pro-BW Plus

This EPD applies to Proteus Waterproofing's Pro-BW® Plus waterproofing system produced in the UK, using raw materials sourced from Europe.

Proteus Waterproofing's Pro-BW® Plus is a liquid hybrid-polymer cold-applied rapid-curing waterproofing system that provides a protective, colourfast, UV-stable and skid-inhibiting surface for flat roofs, balconies and walkways. It is suitable for a range of substrates, including concrete, timber and asphalt.

Proteus Pro-BW® Plus system is covered by BBA 22/6183. The system will achieve an initial life expectancy, for an exposed roof, of at least 25 years. When fully protected and subjected 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.

Proteus Waterproofing's Pro-BW^® Plus system comprises 3 components:

· resin (Pro-BW^® Plus Resin)

· catalyst (Pro-BW^® Catalyst)

· glass fibre reinforcement mat (Pro-Force 450)

A resin base coat is first mixed with catalyst and applied to the surface. Whilst still wet, itis reinforced with a glass fibre reinforcement mat. After curing, a further resin coat (top coat), also mixed with catalyst, is applied to achieve the required overall dry film thickness for the system. Both base and top coats are made from the same resin material and require catalyst.

A primer is applied to some substrates before the base coat, while aggregate and an additional sealer can be applied after the top coat on roofs or terrace areas that will be exposed to pedestrian traffic, or where additional protection and skid-inhibiting properties are required.
