The Liberon Super Wood Glue is simply a strong and effective modern PVA glue, which is a white glue that dries transparently. Any excess glue easily removed with a damp cloth before drying. The glue takes approximately one hour to dry and it will continue to harden for 24 hours depending on conditions. You have a long "open time" which allows you to make any adjustment to alignment of parts before drying commences. This glue is ideal for all Wood including MDF and Chipboard but it will also bond paper and other porous and semi-porous materials. Supplied in 100ml and 500ml plastic bottles which are fitted with a applicator spout that can be closed after use.
