Product properties
Quick Adhesive BOSMAN polyurethane polystyrene is a low-pressure one-component polyurethane adhesive designed for fixing thermal insulation boards in the thermal insulation of flat roofs. Quick BOSMAN polyurethane styrofoam adhesive is used to attach XPS, EPS (white) and graphite polystyrene foamed polystyrene boards to flat roofs covered with galvanized sheet, steel sheet with polyester coating or roofing felt, when performing thermal insulation, also in other construction works - gluing polystyrene to the substrate such as: OSB boards, wood, tar paper, sheet metal, brick, concrete, e.g. in thermal insulation works. The polyurethane adhesive shows excellent adhesion to substrates such as concrete, brick, wood, OSB board, as well as to all kinds of polystyrene, as well as sheet metal (galvanized, steel with a polyester coating) and roofing felt.
Application
The surfaces to be glued must be load-bearing, compact, clean, dry and degreased. Fresh plaster and concrete must be fully seasoned. Molded insulation boards may contain release agents. Carry out an adhesion test. If necessary, sand the back surface of the plates. It is recommended to roughen very smooth, even and impermeable surfaces. The foundations, basement walls and similar underground parts of the building should be cleaned of soil, algae and mosses. Stir the can with glue very well just before use. Screw on the gun. The initial piece of adhesive (approx. 30 cm) is directed to the side (not to be used) until the pressure in the gun is equalized. Apply on one side to the substrate with vertical stripes at 20-30 cm intervals. For slabs 150-160 cm wide, at least 3 strips should be applied. At the underground parts of the structure, always start sticking the panels from the bottom, resting the bottom row on the footing. In other cases, attach the starting strip to support the boards. Place the boards on the substrate after approx. 10 minutes after applying the adhesive, and then press evenly and firmly. The remaining gaps and joints between the boards should be similarly filled with glue. Cover the excavation with soil about 3 weeks after sticking the boards. Remove dirt with a BOSMAN polyurethane foam cleaner. Note that the cleaner may react with the polystyrene board and lead to its damage. Cured adhesive can only be removed mechanically. Places where the adhesive is exposed to UV radiation must be protected within 10 days of applying the adhesive. For UV protection, use plastering mortars, gypsum putty or flexible sealing putties (silicone, acrylic).
WARNING! When used for underground parts of buildings, the adhesive can only be used in light anti-moisture waterproofing systems. Do not use in case of continuous exposure to water (e.g. heavy waterproofing). Do not use on PE, PP, Teflon, silicone surfaces covered with anti-skid or moisturizing agents (eg membranes with a PE film). Do not use on waterproofing substrates with bituminous solvent-based products - risk of damaging the boards (read the product manual carefully and check if the manufacturer provides for the possibility of gluing polystyrene boards). The boards can be glued after the waterproofing coatings are completely dry - see the product manual. Do not use during rainfall and avoid very sunny surfaces. The hardening time is strongly dependent on the ambient temperature and air humidity. The higher the absolute air humidity, the shorter the hardening time of the adhesive.
