If you don't seal marble before grouting, the marble can absorb the grout's pigments, leading to staining that’s hard to remove. Sealing the marble forms a protective barrier, preventing discoloration and making cleaning easier. To avoid this issue, always apply a high-quality sealer to the marble surface before grouting, and let it dry completely. This ensures the marble remains pristine and maintains its natural beauty.
