I'm curious if using marine grade wood glue in applications that won't be exposed to water has any real advantages over standard PVA wood glue. Would marine wood glue provide a stronger bond, or is regular wood glue actually better for non-water situations? Keep in mind, I'm not concerned about price.

Marine glue tends to be a thickened epoxy, which isn't really comparable to regular PVA glue when it comes to bond strength. In most woodworking projects, the internal bonds in the wood itself are typically weaker than any wood glue, meaning that having a super strong glue isn't as essential as you might think. As such, if you don’t need the waterproofing that marine glue offers, you might not benefit much from using it at all.

I always thought marine glue was similar to PVA but just had some waterproof additives. I wanted to use it for a teak project since my regular wood glue isn't holding up. Do you think marine glue could still work better in that case?
