Gluing Teak for a Wet Exposure
This process of watering continues for 15 days when the roof supports are removed. The removed logs are expected to work again whenever a new roof is laid. We require highly water resistant or water proof adhesive which does not weaken the wooden logs even after getting in contact with water. Would the D 4 standard PVA glues work or would any other glue is required. Any advice?
From Jeff Pitcher, forum technical advisor:
I doubt that any PVAs will be able to meet your requirements. A reactive polyurethane may be able to do it but if you need to meet any structural specifications you'll probably want to use resorcinol resin.
From contributor S:
If the logs are supports only and not a permanent structural support, then by all means use whatever glue the guys on this forum recommend. I have used two-part polyureas for a variety of things, from sealing a swimming pool to fixing a leak in a diesel fuel tank.
Like most everything else, preparation and proper application is everything. By and large, I'd say the polyureas and polyurethanes are bullet-proof. After you glue your joints, paint the entire log with a two-part polyurea you won't have any water encroachment. And, new polyurea will chemically bond to old (cured) polyurea, so if your logs get scuffed up, you can recoat them.
