This, the strongest of the Weicon adhesive sprays, is for permanent and highly durable bonding work, especially when the job involves raw, somewhat uneven surfaces. This Weicon adhesive spray, extra strong, is designed for gluing thick textiles like felt, artificial leather or carpeting. It can also be used on soft foams (but NOT rigid foams like polystyrene foam – it eats out craters!), rubber (also foam rubber), leather as well as wood and metal. Its compatibility with individual plastics, especially those that come in thin sheets, should be tested before proceeding further.
The coat resulting from spraying this adhesive will be somewhat thicker than “normal” spray adhesives because it foams up when applied. But this is also the reason that this adhesive works so well on uneven surfaces. Note that its spray pattern is somewhat more spotty and less even than hairspray or PHOTOMOUNT.
By turning the spray head you can continuously adjust the amount of adhesive being released (small, medium, large amounts). The spray comes out of the nozzle in a fan shape and when landing forms a 15 mm thick linear pattern. This makes it easy to quickly and accurately apply it to larger surface areas.
In comparison to the adhesive sprays from 3M, the Weicon sprays are less expensive and have a longer open time (working time), which for many jobs can be a real advantage while for others it might be a negative.
