Yes, a marble shower floor should be sealed to protect it from water damage, stains, and other potential issues. Marble is a porous natural stone, which means it can absorb liquids if left unsealed. In a wet environment like a shower, sealing the marble is essential to prevent water from seeping into the stone, which can cause discoloration, mold growth, and deterioration over time.
Sealing the marble shower floor creates a protective barrier on the surface that repels water and reduces the risk of stains and damage. It also makes the surface easier to clean and maintain. It's crucial to use a high-quality, water-based penetrating sealer specifically designed for natural stones like marble.
The frequency of resealing depends on the type of marble, the quality of the sealer used, and the amount of use the shower floor receives. Typically, it's recommended to reseal marble shower floors every 6 to 12 months or as per the manufacturer's guidelines. Regular maintenance and proper cleaning practices will also help preserve the beauty and longevity of your marble shower floor.
