Description Technical Specs Extended Information
GilsoFlex ™ is a New Zealand manufactured dense black Bituminous/Gilsonite co-polymer, solvent / water emulsion based sealer and paint developed primarily for New Zealand outdoor conditions.
GilsoFlex ™ is ideally suited for sealing and painting of exposed metal roofs, cement tile roofs and steel structures. It is compatible and suitable to be used on Decramastic and Butynol roofs.
GilsoFlex ™ can also be used to seal and water proof timber, ply wood, brick and block work, under carpet concrete floors, Vehicle undercarriage protection etc.

Because of its disinfecting effect, it will retard the growth of moss or lichen.
Substrate surface preparation requirements are minimal as GilsoFlex ™ can be painted straight over minor surface rust.

Roof requires one coat only and 20 Litres will cover approximately 60 to 160 Square Meters, depending on roof surface thus one (1) Litre will cover approximately 3 to 8 Square Meters.

GilsoFlex ™ is intended primarily for surface application by brushing or airless spraying.

A re-coat might be required after 6 to 8 years.

The colour is a deep mat black when fully cured. Once fully cured it can be painted over to change the colour to your choice if required.

3 of 5 Coverage November 12, 2020
Reviewer: Mohammed Farouk from Wellington , Wellington New Zealand  
I have decramastic roof in fairly good condition only few places the coating came off tota roof area is 157mq . I applied this product with roller and brush I used 8 x 20ltr gilsoflex . To be honest I was bit disappointed it doesn't cover much. At this stage I can't say anything about the product itself only time will tell.  I hope my feedback will help someone .
