In the field of concrete element production, ties, sockets, allowances, lifting means, corner mouldings and the like can be attached to steel, plywood or other formwork by hot glue without damage to the mould surface. Form oil possibly present in the formwork has no effect on glue adhesion.
Semko Oy sells hot glue guns, intended for professional use, and specialised adhesives. Glue guns are available with manual or compressed air supply. Three grades of glue are available, with the adhesion time of 1, 3, or 6 minutes (longer adhesion time = stronger joint).
Gluing replaces the formwork surface damaged or stained by fastening techniques and dramatically extends the lifecycle of the formwork. In the same way holes in the element formwork can be treated without nails, which makes dismantling easier and significantly reduces board material losses.
In particular, gluing facilitates formwork assembly related to long or complicated channels on the element surface. Gluing is also much more flexible and user-friendly as compared to other procedures.
