Influence of glue type and way of bonding on joint swelling of worktops was researched. Impact of chipboard type and way of front edge processing on swelling was also studied. For testing purposes 39 mm thick kitchen worktops, made of chipboard type P2 and P7, were used. Surface was covered with 0.8 mm thick decorative laminate. Front edge was processed with ABS front band, 2 mm thick, or it was postforming processed. Termosil N-6, Helmipur SH 100 and Dorus PU 300 were used for bonding. Test objects, bonded either in a way of firm bond or in a way of lamella and groove, were tested according to SS 83 6120 standard. It was found out that only sort of glue affects joint swelling of worktops. The best results were attained with a seal on polyurethane basis, the worst with polyurethane glue. Realization of bonding doesnćt affect quality as regard swelling. Bonding with lamellas assists to fit and enables quicker and easier positioning of 2 plates on same level. Type of chipboard used does not have any impact on quality of joint, it affects swelling intensity only. Type of front end processing does not have any impact on joint quality.
