How do the costs of sealing marble compare to sealing concrete outdoor planters?

When it comes to outdoor planters, both marble and concrete are popular choices due to their durability and aesthetic appeal. However, sealing these materials is essential to protect them from weathering, stains, and moisture damage. The cost of sealing marble is generally higher than sealing concrete. Marble requires specialized sealants to maintain its luxurious finish, with costs ranging from $3 to $10 per square foot, depending on the product and labor. Concrete, on the other hand, is more affordable to seal, typically costing $1 to $5 per square foot. While marble offers a premium look, concrete is a cost-effective and low-maintenance option for outdoor planters. Consider your budget and long-term maintenance needs when choosing between these materials.
