State a purpose you would want something else for.
I have used PVA Glue instead of padding glue for three years now for my ncr jobs sheets and telephone answer pads. I have had no problems with them so far, so yes, you can use PVA Gldding glue.
Because PVA is the appropriate glue for wood.
pva glue is not waterproof, however, some recommend mixing with nail hardener to make a homemade nail glue
PVA glue is a liquid till it sets in use, then it's a solid.
pva
yes but its not the best thing to use
People do not generally put PVA glue onto walls. We can't ask questions , so you must figure out why you did that, and how you are going to get around the problem it's now causing.
it is best to use decopatch glue but i am trying PVA it should work
No, it won't work. Use a good waterproofer like Thompson's , it's cheap and worth it.
Prime it first with an autobody primer spray.
Yes, it would be good for that.
If it's hardened it's possibly too old to use.
