By wicking the cement, capilliary action allows it to travel the length of the joint insuring a water-tight seal.
Acrylic:
The one big area ofter overlooked is the cut edge preparation before bonding. The saw action leaves a surface pitted and uneven. Due to the viscosity of the cement, (thin), these rough edges need attention before actual assembly. Then a propane blow torch set way, way low to sort-of flame polish the final mating surfaces.
There is a thicker viscosity cement out there that fills some imperfections when cementing, but not nessessary for this application, only on high pressure sensitive work.
