Author Topic:   Repairing polystyrene foam with CA glue (Superglue) and baking soda

According to Wikipedia article http://en.wikipedia.org/wiki/Cyanoacrylate , one use for cyanoacrylate-based glue (i.e., CA glue) is to mix it with baking soda to repair damaged polystyrene foam. The article states,
quote:
When added to baking soda (sodium bicarbonate), cyanoacrylate glue forms a hard, lightweight filler/adhesive (baking soda is first used to fill a gap then the adhesive is dripped into the baking soda). This works well with porous materials that the glue doesn't work well with alone. This method is sometimes used by aircraft modelers to assemble or repair polystyrene foam parts.

Has anyone tried using CA glue mixed with baking soda to repair or replace the foam inside a Boston Whaler hull?

Whaler uses polyurethane foam, not polystyrene.
