Polyurethane foam – polyurethane foam sealant − rather new product in the construction market. Scope of application extensive – it acts as the warming, isolating and sticking together substance.
Instruction
1. One-component MT has properties: to fasten separate parts of designs; to condense; to isolate; to warm. Quality foam has to stick to surface, but not to flow down, be elastic, not to shrink, after hardening not to crumble. She is: pistol (professional), household, winter, summer, all-weather, heat-resistant. Has replaced with MT the traditional heat-insulating and condensing materials: tow, bitumen, mineral wool ribbon.
2. Polyurethane foam is applied during the constructing facilities, repair of household and industrial buildings. It is widely used for splice closure between parts of designs, at closing up of slots and cracks, interpanel seams, filling of emptiness near window and door openings. On foam "put" door and window cases, at the same time additional fixing is not required by nails or self-tapping screws. By means of this universal material it is possible to paste reliably heater, for example polyfoam plates, to wall. Otlichy means for closing up of places of adjunction of sanitary constructions, ventilation and extracts.
3. MT apply to elimination of defects (cracks) in roofing materials and also zapenivat slots on watercrafts – rafts, boats. Advantage of foam also that it is convenient to close up emptiness of any configuration it is intended for work with many materials: tree, concrete, foam and slag stones, glass, metal, brick. Does not interact with teflon, polypropylene, silicone, polyethylene. Foam zashtukaturivatsya well and closed up by putty.
4. Fill with heat-resistant foam openings between floor slab and chimney, use it at installation of fire-prevention hatches, doors. Winter structure warm communications – the pipes and hoses located out of warm rooms. It is not recommended to use polyurethane foam as sealant between timber works. It has shrinkage, is insufficiently elastic, seams in addition should be pressurized.
5. It is necessary to Zapenivat emptiness on 1/3 depths, stiffening, foam extends and fills all space. Apply MT with small expansion to narrow slots. Effective life has important value, the overdue goods have no stated properties. After hardening, foam demands processing. Surplus cuts off knife, sticks surface with assembly tape and paints over or plasters.
