Can temperature	from +10°C to +25°C
Ambient temperature during application and bonding	from -5°C to +30°C

The temperature of the substrate and air during the works should be from -5°C to +30°C. In the case of a substrate made of bituminous felt, galvanised steel sheet metal or galvanised steel sheet metal with an organic coating, work can be carried out at substrate temperatures of up to +50°C.
Works should not be carried out during precipitation, strong sunlight and strong wind.
Before bonding insulation boards with STYROPUK Roof, the surface must be properly prepared. The bituminous felt must be well heated into the substrate. The substrate should be even and levelled. The permissible deviation of the surface from the flatness of the wall must not exceed -4 mm and +2 mm. The deviations are to be measured with a 2 m long patch with an accuracy of 1 mm. The substrate must be clean, free of frost, ice and water stagnation. In addition, it must be free of dust, oil, grease, paint residues and other contaminants that could reduce the adhesion of the adhesive to the substrate.
STYROPUK Roof can be applied to seasoned substrates and bituminous coatings fully bonded throughout the whole section. It is not permissible to apply the product to a damp substrate. Substrate moisture adversely affects the foam structure.
Thermal insulation boards to be fastened should have straight edges. EPS boards with reduced absorption and XPS boards should be sanded before the adhesive is applied to increase its adhesion to the surface.
Apply STYROPUK Roof to the thermal insulation board in at least four vertical braids of approx. 3 cm in diameter. Equal spacing of 20 - 30 cm between the strips should be maintained, while observing a distance of 3 cm from the edge of the board.
For panels wider than 1000 mm, more strips are required. In the corner and edge areas, the strips should be applied more closely, every 15 cm (see table in Technical Data Sheet).
Lay the thermal insulation boards alternately. In the case of trapezoidal sheet metal, the adhesive should be applied from the highest point of the upper sections of the profiles. If work is to be interrupted for more than 15 minutes, lock the trigger, leaving the can screwed on until the next use.
Glue the thermal insulation boards to the substrate as soon as possible after the application of STYROPUK Roof. Open time is 4 minutes maximum. Place the board on the insulated roof surface and adjust the alignment if needed. The curing time of the adhesive is approx. 24 hours.
Bonding with does not obviate the need for STYROPUK Roof mechanical fixing of the thermal insulation boards if the technical design provides for such fixing.
Before use, please read the application details in the product's Technical Data Sheet.
