Wood glue difference outdoor - indoor ?

[dymlingen]

What is the actual difference between outdoor and indoor wood glue? I assume that outdoor glue is moisture resistant. But then you should be able to use outdoor glue indoors as well, and then you'd only need one type of glue. Are there any disadvantages to using outdoor glue indoors?

The outdoor glue becomes harder and less flexible than the indoor glue, right?
For example, when I installed conti plank flooring in the attic, I was advised to use plenty of outdoor glue on the joists and tongue and groove before screwing the boards down.

Outside doesn't dry as quickly.

I was actually standing and reading the bottles of Casco's indoor and outdoor glue the other day. The list "adheres to..." was slightly longer on the indoor glue bottle, meaning it mentioned a few materials that the outdoor glue did not. Unfortunately, I can't remember which ones. The outdoor glue also tends to be a bit more expensive, but only by about a tenner per liter.

I have also wondered.

And then a joker jumps into the discussion.

Vinterlim then ...

After a look at Casco's datasheet, the indoor glue contains 25-50% polyvinyl acetate (PVA), while the outdoor glue contains 50-75% PVA, which is probably the main reason it is waterproof. The outdoor glue also has a more toxic preservative/antifungal agent.

The winter glue contains 10-25% ethanol and 10-25% kaolin (a clay mineral, probably as a thickening agent). The winter and indoor glue contain diethylene glycol monobutyl ether acetate, which is the solvent that makes them dry faster than the outdoor glue.

Exactly. Alcohol so that it doesn't freeze into ice in the packaging.

I think the winter glue becomes a bit more elastic when it dries. At some point, I received the recommendation to glue the floor chipboards with winter glue (even though it was in the middle of summer).

I think the winter glue becomes a little more elastic when it has dried. I was recommended at some point to glue the floor particle boards with winter glue (even though it was in the middle of summer).

Same here, but I thought the winter glue became harder...

Everyone who has been recommended different types of glue for flooring: shouldn't you use floor adhesive instead?

Furthermore, I'm a bit curious about that datasheet from Casco. It feels a bit strange to have such large intervals like 10-25%. Why so imprecise?

Another question now that we are on the topic of glue: in Sweden, there is basically only Casco available in regular stores. The Americans, on the other hand, seem to have a multitude of glues to choose from. Why is this? The reason I'm asking is that I would like a glue with a slightly longer open time (or whatever it's called) so that the floor can be adjusted on site, and I can bend glue laminated wood in another project. It doesn't seem to be available in regular stores.

It's not about flooring, but gluing flooring chipboards to each other and to the joists.

Ranges for ingredients are usually given so that competitors cannot copy the "recipe".

I think there is quite a lot of wood glue to choose from in Sweden:

I have the opposite experience, I wanted the usual tried and tested Casco but alas my hardware store has stopped stocking Casco.
