Paving joint compound

[Marnhullman]

I have a large area of paving that was laid 2 years ago. The builder used joint compound, which looks great, but it doesn't seem to be as tough as I expected and there are some joints that have small sections that need re-pointing. I'm okay to do the job but I only need a very small amount of the compound. From what I've read once the container is opened the jointing compound must be used within a few days but since I'll only need a small amount there would be huge wastage.

Can joint compound be stored for later use once opened or is there something similar available in small quantities?

Thanks

No.

You can prolong it for a short while by filling the container with water,
