All of our blow up stand up paddle boards are intended to be inflated to 10-15 PSI (max tested PSI 25). You should find the last 30-40 pumps to be fairly difficult, but it's worthwhile to get it to full inflation. Please note, the gauge that comes with our pump will not register the PSI until the board is at at least 7+ PSI.
Don't worry--there's no way to over-inflate or damage your board with this pump--so keep pumping until you get a read on your gauge. Once you think your board is fully blown up, take a break and then pump it up 10-15 more times.
One note on inflatable paddle boards is that they can hold air perpetually. At our shop we only "deflate" when we need to transport them in small spaces. You can leave your blow up stand up paddle board inflated for however long you you choose. One of the primary benefits of an inflatable board over a hardtop board is that it's almost impossible to damage, so many users will even transport them completely inflated. It's not necessary to inflate and deflate after each use.
