Has anyone used Bostik 915 or Chem-Calk to glue in decks or bulkheads. It is a Polyurethane adhesive and sealant. We use it all the time for various construction items and it is incredibly strong. You can glue a board to concrete and it wont come off. Just thought it might be easier to get the items placed. Could come back later with thickened resin to make fillets.
