Gluing of polyfoam is required both in internal, and in external works. As requirements to them different, and the glue structure is used unequal. Process of mounting of plates of polyfoam of differences has no.
Polyfoam can be used as heat insulator and to be mounted on external walls of the building, but can act also as finishing material for works indoors. For example, for registration of ceiling figured foam tile or molding.
What glue is necessary for mounting of ceiling tile from polyfoam?
Glue for polyfoam intended for internal works can be made water-based or with addition of synthetic or natural substances. As the last most often use bone meal. Such glue is bad the fact that in space between ceiling and tile colonies of the harmful microorganisms feeding on organic chemistry can develop. When using such binding before mounting of tile it is recommended to process ceiling primer with properties antiseptics. Therefore when choosing glue it is necessary to pay attention to its structure.
If glue for water-based polyfoam is acquired, it is necessary to consider that it can be used in rooms where air temperature is not lower +4os. The feature of these structures is that they long dry. The optimum choice for internal works with polyfoam – glue on the basis of solvent (alcohol, toluene, acetone). It quickly "grabs", does not leave marks on tile, is not hygroscopic. Therefore for mounting of ceiling foam tile it is recommended to use "Liquid nails", "Titanium", "Eltitans", "What naset", "Moment-Montazh No. 40".
Than to paste polyfoam on external walls of the house?
On facades of buildings metal elements quite often meet. For gluing of polyfoam to them "Liquid nails" are necessary. Metal is previously degreased, remove rust and old paint. Only in this case high-quality compound of materials will be provided. If the facade is executed brick or concrete, the most popular mounting mode of polyfoam – gluing on polyurethane foam. The wall surface is previously cleaned from dust, then thin layer spray foam. Put polyfoam and hold it in this situation during 20-30 sec. It is possible to paste polyfoam on the wooden, plastered, concrete, brick basis by means of single-component polyurethane structures. They and are called: "Glue for extruded polystyrene foam". These structures in plastic tanks of different volume are on sale. In cylinders "Liquid polyfoam" by means of which it is possible to close up gaps between heater cloths is on sale. But for this purpose it is possible to use also frost-resistant polyurethane foam.
