Start by thoroughly cleaning the marble bathroom vanity. Use a pH-neutral marble cleaner and a soft cloth to wipe down the surface, removing any dirt, grime, or soap residue. Make sure the vanity is completely dry before moving on to the next step.
Be sure to cover the entire surface, including the edges and corners, with a thin, even coat of sealer. Avoid applying the sealer too thickly or letting it puddle, as this can result in an uneven finish.
Let the sealer penetrate the marble for the recommended time as per the manufacturer’s instructions. The sealer will need about 10-15 minutes to absorb into the pores of the marble and create a protective barrier.
After the recommended time has passed, use a clean, dry cloth to wipe off any excess sealer from the vanity surface. Make sure to remove all the excess sealer to prevent streaks or haze from forming on the marble.
Let the sealer cure for the recommended time, usually 24 to 48 hours. During this time, avoid using the vanity or placing any items on it to allow the sealer to fully cure and create a durable protective barrier.
