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 +60°C.
Works should not be carried out during precipitation and strong sunlight.
Before bonding insulation boards with STYROPUK Foundation, the surface must be properly prepared. The substrate should be even and levelled. The bituminous felt must be well heated into the substrate. The permissible deviation of the surface from the flatness of the wall must not exceed -4 mm and +2 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 Foundation 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 Foundation 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 2 - 3 cm from the edge of the board. For panels wider than 1000 mm, more strips are required. If work is to be interrupted for more than 15 minutes, lock the trigger, leaving the can screwed on until the next use.
The bonding of the thermal insulation boards to the substrate should be carried out as soon as possible after the application of the adhesive. Open time is 5 minutes maximum. Place the board on the insulated surface and adjust the alignment using a mounting batten if needed. The position of the boards can be adjusted for up to 10 minutes after they are placed on the insulated surface.
Thermal insulation boards are to be supported on the footing offset and, if this is not possible, to be supported mechanically until the adhesive has set (approximately 10 minutes). After 2 hours, the boards are ready for further processing. An additional mechanical fixing is required in the plinth area.
Before use, please read the application details in the product's Technical Data Sheet.
