I am starting on a project of bending and gluing seven layers of 1 1/2" x 1/2" x 8' poplar to form (sixteen) curved 1 1/2" x 3 1/2" beams for a greenhouse. Based on web research, I've determined that DAP Weldwood Plastic Resin Glue is the best choice and ordered a 4 1/2 pound tub online from A*. It arrived with an expiration code on the top sticker which, according to DAP support, expired in two days. They recommended returning it which I did, for an exchange. The replacement was from the same lot.
It could take me as long as 3 months to glue up all these beams. The Weldwood will by then be 3 months expired. I've read the stories of very expired Weldwood Plastic Resin being gritty and not setting up. My sense is that if the Weldwood mixes smooth (not gritty), it will cure just fine - but with all the work going into milling and steam bending the layers, I want to make sure I am making a wise choice.
What would you suggest?
