When gluing outdoor joints (such as front door gluing), the effects of heat (e.g. direct exposure to sunlight) may result in tension in the wood and glued joints softening. Thermoplastic adhesives as well as PUR glue in a dispensing system or PUR gun glue are not suitable for these kinds of applications. The processing time and setting time, as well as the pressing time, are affected by working conditions such as ambient temperature, surface temperature, air humidity or material moisture, absorption level of materials, application quantity and tensions in the material. The viscosity of the one-component D4 glues may increase while being stored. Stirring the glue without adding water makes it free-flowing again. The viscosity can thus be adjusted by stirring alone. Storage does not affect the gluing parameters. The glue container must always be stored firmly closed and in a frost-free environment.

Wu00fcrth white glues are not suitable for use in the static range. Specially approved adhesives must be used for this purpose. Wu00fcrth glues may only be used for non-load-bearing applications.
