Using a baked portafilter doesn't require anything different to a regular one. What it does do is show you flaws in either your beans (too old, shit supermarket beans etc) or your technique.
If it's pissing out everywhere then I guess the grind is far too course or the beans are too old. Or the tamping technique is flawed etc etc etc
As Bombcup often says, home espresso is a pain in the arse
