It made fitting the joints harder
I’m sorry, but I did not like this paste. It goes on well and solders well, but I found that my old paste had a lubricating quality that this does not have. When I cleaned and prepped the pipes, they were harder to fit together after I applied this paste than when they were dry.
I completed a dozen joints and couldn’t take it any more – I’m ordering the number 5.

Great quality flux
Originally recommended by a Home Depot associate in store, I have used this solder paste on numerous occasions over the years for sweating residential copper piping. It goes on easy, does not clump, and allows solder to flow beautifully.
I just recently completed a residential plumbing project that required over 20 copper piping welds of size 3/4" and 1/2". The flux was very easy to work with. Each and every one of the welds held for a 100% success rate.
In addition, this flux is water soluble, so i have no concerns of any resident contamination of the water supply.
Highly recommended.
