Purple primer left on over night: can I use it?

Question

I am using Oatey purple primer with Oatey medium gray pvc cement. This is a 2 inch PVC pipe job for pool pump to filter.

I have a joint where I applied purple primer then realized I am not ready for the fitting so I need to leave it overnight. This fitting is to an ABS filter valve. I realized I need Green ABS to PVC transition cement and will get some tomorrow.

Can I add some fresh primer on the PVC pipe before I glue it the next day with green PVC to ABS cement? Or must I cut off that piece of pipe and start over?

you can use it now no need to cut it off. Most people don't let the primer dry prior to fitting the pieces. I thought PVC-ABS was for vent lines not pressure lines — Ed Beal, Mar 21 '16 at 14:03

yes, you can use it, just re-prime it. You'll see that the fresh coat of primer with melt right through the dried primer.

How long can something that's primed sit before you should reapply primer? – Mazura Mar 21 '16 at 19:28
@Mazura if it's still wet, you can use it. If it's dried, reapply. – DrewJordan Apr 01 '16 at 17:34

Oatey says the cement is to be applied while the primer is damp.

So, apply a small amount of new primer before gluing and glue after it has dried for a half a minute or so.

Oatey says NOT to use primer on ABS only cleaner.
