Yes, you need to prime plasterboard before tiling. Priming the surface ensures good adhesion between the tile adhesive and the plasterboard. It prevents moisture from the adhesive from being absorbed too quickly by the plasterboard, allowing for a stronger bond. Use a suitable primer recommended for tiling on plasterboard, and make sure it's fully dry before you start tiling.
