Briwax will turn into a liquid in hot weather. This in no way diminishes the quality of the product. In fact, Briwax is designed to turn liquid and can be used in a liquid state (see Using Briwax in a Liquid State on this blog).
Simply allow the container to come to room temperature – either by placing the container in the refrigerator for several hours, or by bringing the container into an air conditioned room – and Briwax will return to a paste form.
In warm weather, you might want to place the container of Briwax in an air conditioned room the night before you plan on using it. The container can be placed in the refrigerator to speed up the process.
Since Briwax is to be applied sparingly, the paste form of the wax will allow a less wasteful application.
Just remember, the quality of your Briwax is just fine – either in a liquid state or paste form!!
