Shukaku's technique can seal targets upon completion of the technique unless you are referring to his natural Cursed Seals, which need a medium (such as sand or the Rasengan). Even so, sealing the target does not stop them from using jutsu as seen when Madara used his Susanoo to escape from Shukaku's jutsu. If that's the case, Gyūki can still used Tailed Beast Balls to break free from the technique or Killer B can use Lightning Release to break out of the technique. Shukaku can use Tailed Beast Balls, but not at the same rate as Gyūki unless shown or stated otherwise. Also, if Madara can break through the sand with a Susanoo sword (which was only in its humanoid stage) after the sand was already enhanced with Cursed Seals (and it was part of Shukaku's body), wouldn't a tailed beast ball easily be able to blast through Shukaku's sand? Even Gaara's sand wasn't able to handle a chidori. I doubt it could withstand a Tailed Beast Ball or several. Gyūki also survived a Tailed Beast Ball from the Ten Tails, so I'm not sure Shukaku's would do much damage to it.
