  • Using biscuits for exterior applications

    Hi
    Does anyone make biscuits for exterior applications? I know Dominos have an exterior grade material.
    If anyone has used them, please let me know
    Thanks

    There are plastic biscotti from Lamello, possibly also from/through Hafele.

      Hi David,
      Yes, I was looking at those. Thanks for the reply. They may be just the ticket since they do not need glue.

        why could you not use the regular biscuits? I mean they are all glued in place and then covered with materials that should get sealed. Seems the glue would pretty much seal them up and keep them from rotting away and coming loose.

          Mark, it does seem that way, but what if the biscuits gradually swell due to higher humidity (installed into materials that stay wet for longer periods). The glue used may not be vapor impermeable. I have occasionally used beech biscuits outdoors, completely saturated and encased in epoxy, and hoped for the best, but a box of plastic ones lasts for years, worth having.

            What do you use for glue with the plastic biscuits? Urethane like PL or Sika or something else?

                Epoxy is probably best but I've used PL Premium, my favorite glue.

                  Rich the nice thing about the lamello biscuits, is they work with Azek so humidity isn't a problem. They also make biscuits that lock as well as align miters which are useful for pre assembly. I agree with David that epoxy is the way to go for exterior glue ups.

                    What's the thinest material you would feel comfortable using the plastic biscuits I.e. 7/16" beveled siding

                      we use plastic with epoxy glue,

                      they are actual sold for use with a decking system.

                      you could always make a few out of hardwood using a template and a router if you dont need that many,

                        Hi
                        Thanks for all the suggestions and greatly appreciated.

                        I found the Lamello plastic ones on Amazon so I will give them a try. They claim to be self locking, but I think we will have the epoxy ready just in case.

                        We are looking to use these on some 5/4 x 6 cedar decking around a swimming pool just to keep the butt joints aligned. I was concerned that the wood biscuits would rot out after a few years.
                        I will let everyone know how it goes.

                          Would anyone feel comfortable using this system on 7/16". Hemlock beveled siding.To. Miter the outside corners. Instead of corner boards. I thought there would not be enough material left and it would bubble through. The architect wants clean lines but has conceded to use 1 1/4" corner boards. Do any of you gentleman? Think these plastic biscuits would work?

                            That would be quite fussy to install. It would be much more like a furniture job than a typical siding install. I think you'd need to make some sort of clever jig to position the biscuit cutter, and bring each siding piece to the jig.

                              But doable? Suppose a mock up would help
