The DANOFLEX GRP system should be applied in dry conditions between 5°C and 30°C ambient air temperature. Do not begin if conditions could fall outside of the temperature range and/or if rain appears likely.
A: Application of the DANOFLEX Primer. DANOFLEX Primer requires DANOFLEX Catalyst at a minimum of 2% and a maximum of 4% depending on temperature.
1. Ensure surface to be coated are dry and have been fully cleaned, made good and prepared as in accordance with recommendations.
2. Stir the DANOFLEX Primer thoroughly in the original container, mixing from top to bottom.
3. Pour the calculated amount of primer into calibrated bucket / suitable container on weighing scales and replace lid on container to prevent contamination or unnecessary losses to atmosphere. Do not attempt to mix more than 5 kg (4.5 litres) at one time, and during the hot summer months this should be considerably reduced.
4. Add the required number of DANOFLEX Catalyst scoops to the decanted DANOFLEX Primer. Thoroughly stir the catalyst into it is fully dissolved into the resin for a minimum of 2 minutes.
5. Once hardener has been stirred in apply the DANOFLEX Primer by roller (or brush if access restricted) to the prepared surface at the required coverage rate within the range of 4-6m2/Litre (3.5 - 5.3m2 / kg). Ensure an even, uniform application across all surfaces. Important
- If coating OSB3 TG4 boards, the primer should be applied to the board joints by brush ensuring that the primer fully fills the gaps.
6. Touch in any suspect areas where necessary and then allow to dry before over-coating. The cure time is approximately 30 - 60 minutes depending on application conditions.
7. Ensure the primer is over-coated within 7 days. After this period consult your distributor for advice.B: DANOFLEX GRP Resin Application Instructions. DANOFLEX GRP Resin requires catalyst at a minimum of 2% and a maximum of 4% depending on temperature.
1. Stir the DANOFLEX GRP resin thoroughly in the original container - mixing from top to bottom. Ensure any settlements are dispersed throughout the liquid.
2. Pour the calculated amount of resin into calibrated bucket / suitable container on weighing scales and replace lid on resin can to prevent contamination or unnecessary losses to atmosphere. Do not attempt to mix more than 10 Kg / 7 litres at one time, and during the hot summer months this should be considerably reduced.
3. Add the required amount of catalyst direct into the measured out resin and mix thoroughly, stirring for a minimum 1.5 minutes. Ensure the powder is thoroughly dissolved into the resin.
4. Apply by roller approximately two thirds of the required amount of resin onto the roof surface. Roll out the fibreglass CSM over the resin, ensuring the mat is correctly orientated so the straight cut edge is overlapped by the feathered edge of the next strip. Work the CSM fibres into the DANOFLEX GRP resin before applying the remaining one third of resin. Leave matting to soften for 2 minutes and consolidate with the roller until the matting appears “swirly” and no straight fibres remain. Ensure a closed, pinhole-free surface is achieved.
5. Inspect thoroughly and if there appear to be any areas with insufficient resin (voids, prominent fibres or spots remaining white) apply extra resin as required. Allow to cure (30 - 60 minutes depending on conditions) before walking over the membrane.
6. A second coat of DANOFLEX GRP resin should be applied at a minimum coverage rate of 0.5 Litres/m2 (0.7 kg/m2). Decant and add catalyst as previously described, applying by roller ensuring an even and uniform thickness. Allow to cure and then check for pinholes / misses and rectify accordingly. Important - The second coat should be applied as soon as possible, there is a maximum over coating time of up to 7 days. After this period cleaning with acetone will be required which will allow another 7 days over coating time. If left for longer than 14 days consult your distributor for advice.
