The Great Debate: Do Granite Headstones Need to Be Sealed?

When it comes to commemorating the lives of our loved ones, granite headstones have long been a popular choice for their durability, aesthetic appeal, and timeless beauty. However, a question often arises in the minds of those responsible for the care and maintenance of these monuments: do granite headstones need to be sealed? This article delves into the great debate surrounding the sealing of granite headstones, examining the arguments for and against this practice.

Understanding Granite:

Granite, a natural stone formed from cooled magma, boasts exceptional hardness, resistance to weathering, and an innate ability to withstand the test of time. These qualities make it a preferred material for headstones in cemeteries and memorial gardens. However, despite its inherent durability, granite is not immune to the effects of the elements and environmental factors.

The Case for Sealing:

Proponents of sealing granite headstones argue that applying a sealant helps protect the stone from various potential threats, such as:

  1. Stains: Granite is porous, meaning it can absorb liquids that may lead to unsightly stains over time. Sealing creates a protective barrier, preventing liquids like rainwater, bird droppings, or tree sap from penetrating the stone and causing discoloration.
  2. Mold and Mildew: In damp and shaded areas, mold and mildew can thrive on the surface of granite. Sealing the headstone can inhibit the growth of these unwanted organisms, preserving the stone’s appearance.
  3. Freeze-Thaw Cycles: In regions with harsh winter climates, water absorbed by granite can freeze and expand, leading to cracks and damage. Sealing helps mitigate the risk of freeze-thaw cycles, safeguarding the structural integrity of the headstone.
  4. UV Radiation: Prolonged exposure to sunlight can cause the color of granite to fade over time. Sealing acts as a protective shield against the harmful effects of UV radiation, preserving the stone’s original hue.

The Case Against Sealing:

Opponents argue that sealing granite headstones is unnecessary and may even have drawbacks:

  1. Natural Aging: Granite naturally weathers over time, developing a unique patina that adds character and charm. Sealing the stone may impede this natural aging process, preventing the headstone from acquiring the distinguished appearance that comes with the passage of time.
  2. Breathability: Granite is a breathable material, allowing moisture to evaporate through its surface. Sealing the stone could trap moisture within, potentially causing more harm than good by promoting the growth of mold or contributing to other issues like spalling.
  3. Maintenance Challenges: Sealed granite may require periodic reapplication of sealants, adding to the maintenance demands. Improperly applied or expired sealants may result in an uneven appearance or compromise the stone’s protective qualities.

In the ongoing debate over whether granite headstones need to be sealed, there is no one-size-fits-all answer. The decision to seal a granite headstone depends on factors such as location, climate, and personal preference. While sealing can offer protection against stains and environmental threats, some argue that allowing granite to age naturally has its own merits. Ultimately, those responsible for the care of granite headstones should weigh the benefits and drawbacks, considering the specific circumstances surrounding each memorial, to make an informed decision that honors the memories of the departed.
