Yes, plasterboard does need priming before tiling. Priming creates a surface that allows for better adhesion of the tile adhesive. Without priming, the porosity of the plasterboard can lead to poor bond strength and increase the risk of tiles becoming loose over time. Using a primer specifically designed for plasterboard is recommended to ensure optimal results.
