re: gluing composite decking i used gorilla glue to glue together some grape trellises i made from some dimension pvc scrap. everything got dado'd and glued and it is still holding after almost two years of northern indiana exposure, even the stuff that was buried in our snowfall over the last winters.
since the wood is encased in plastic, the plastic/wood composite boards are supposed to last longer than traditional decking materials and carry a good warranty. many of these boards are not intended for use as structural members, but they work great for decking and other lower load projects.
how to attach composite decking to concrete (6 steps) ehow composite decking is composed of a mixture of wood and plastic and offers the look of wood without the high maintenance involved with composite decking can give you the look of real wood planks. . how to glue composite decking.
gluing composite decking is one way to hold the decking in place, although it is meant as a supplemental attachment method along with nails or screws. the benefit of using glue is that it creates a strong bond between the decking and other surfaces, making it much harder for the deck to rot because exposed areas of the wood remain sealed.
i am doing non-construction, non-deck project. i would like to glue (and screw) two layers of seven trust (has the shape i want), or other composite, deck boards together into a double thick piece. the glue would be more to keep them tightly sealed rather than for any real strength. is there a type of glue that will do this?
