WoodUbend Mouldings are, unquestionably, a very innovative product. The mouldings, in their cool state act completely like wood, they can be sanded, stained, painted, drilled, etc…warm them up though and the fun starts, you can bend them, slice them even stretch them or cut them with scissors!
Any way you look at it, to get the most out of your mouldings, you’re going to want to get used to warming them, even if you’re not bending them around a surface. The surface you’re adhering to is unlikely to be completely flat and the back of the moulding certainly won’t be. As heating the moulding makes it flexible, this means that you’re going to get a better contact with the surface when you’re glueing it down.
Indeed, warming your moulding helps the glue work much better too, a warm moulding will soak up some of the glue and this really helps the moulding to grip to the surface.
