I'm going to build new boxes for my beehive, and using an 18mm thick glued laminated board would be perfect. But can it withstand outdoor conditions?? I plan to paint the entire hive with Linoljefärg: 2 layers thinned and 2 layers unthinned. It's complicated to glue planks together for this, and the ready-made boxes available don't fit my hives.
How did it go? I am also wondering how glue-laminated boards work outdoors, the so-called hobby boards are glued with interior glue so untreated it probably works poorly. But how is it IF they are properly painted, for example with an acrylic system and made of spruce?J JGS85 said:

Bump!
I have given up on glulam outdoors where it is exposed to moisture, it doesn't last. Not by the sea on the west coast anyway. I have glulam in the trim boards on the glazing, they have started to rot after just a few years despite good moisture protection. They practically rotted from the inside out...
Now I will try to find regular trim boards of sufficiently thick dimensions instead, but it's probably hopeless. I'll probably have to invent something, I'm thinking of two parallel boards that are beveled with a slope outwards where they meet each other. It certainly won't last a shorter time...
