In this article, we will discuss about Flagstone, its origin, properties, and varied flagstone indoor flooring options. 

Knowing Flagstone – Origin and Properties

Flagstone refers to thin, flat slabs of natural stone. It is sourced from sedimentary rocks like limestone, sandstone, slate, etc., when their surface naturally splits along the bedding planes.

While the slab looks unique owing to the flat surface, flagstone is often found in irregularly shaped pieces, making it look even more interesting when laid as indoor flooring. 

Common Properties of Flagstone

Durable

Flagstone is naturally strong, exhibiting high compressive strength. It can withstand heavy loads and foot traffic, making natural flagstone flooring indoors ideal. 

Aesthetic

Flaunting earthy hues with irregular shape, imparting a natural feel, flagstone is one of the timeless natural stones, amping up the aesthetics of both interiors and exterior spaces. 

Slip-Resistant

Owing to the natural texture of a flagstone surface, it’s slip-resistant. This property makes flagstone a popular pick for wet areas.. 

Eco-Friendly

Being a natural sedimentary rock, flagstone is an eco-friendly material that demands minimal processing post mining from a quarry. 

Heat Resistant 

Flagstone is one of the cool materials, resistant to heat. This property makes flagstone flooring indoors an excellent choice to maintain thermal comfort.

Debunking the Common Myth – Porosity of Flagstone

One of the most common misconceptions with respect to flagstone is that it is porous in nature.

In reality, not all types of flagstone are equally porous. The porosity depends upon the mineral composition. For example, sandstone is more porous as compared to bluestone or slate.

Despite the porosity levels, flagstone works well as an indoor flooring material with proper sealants. Sealing it properly helps minimize water infiltration and adds to the longevity of the stone.

• Ensure to review your budget before making the final choice. While limestone and sandstone are economic picks, travertine and bluestone flagstone flooring indoors are considered premium picks.
• For wet areas, consider the idea of going for denser stones like slate and bluestone rather than limestone or sandstone, which demand regular sealing.
• While flagstone flooring may look irregular, it demands skilled craftsmen for installation. Ensure to hire stone experts for flawless flooring.

How to Install Flagstone Flooring Indoors?

• The installation process begins by laying a proper sub-base. Make sure that the floor is clean and precisely leveled.
• Add a mortar bed on the subfloor to ensure adhesion and better stability of the flooring.
• Before fixing the flagstones, arrange them in a dry run to plan the desired pattern that minimizes the cutting of the stone.
• Start laying the stones on the mortar bed and pressing them firmly. Make sure to maintain consistent joint spacing between each stone piece.
• The spacing between joints will depend on your design preference. Whether it’s a wide traditional joint or modern sleek joints, ensure the seal with grout or mortar.
• After the stones have been laid, apply sealant to protect the flooring from moisture and stains.
• Make sure to follow resealing periodically based on the type of stone and application. 

How to Maintain Flagstone Flooring?

Flagstone flooring indoors demands simple but consistent maintenance efforts. Here’s the stone-care routine: 

Plan Regular Cleaning

Don’t let grit stick to the flagstone surface, as it will end up adding scratches to the surface. The best way to prevent that is by sweeping and vacuuming regularly.

Remove Stains

Stain removal from flagstone flooring doesn’t demand highly acidic solutions. Rather than damaging the natural appearance of stone with harsh solutions, use warm water with a mild dish soap and brush the stains with a soft brush.

Sweep Regularly

Simply dry-sweep the floor daily to keep the dirt away.

Degrease Naturally

Kitchen flooring is prone to grease formation. Degrease the floor by mixing water and baking soda and allowing it to sit on the surface before clearing it. 

Seal Periodically 

While several types of flagstones are porous, make sure to seal them periodically for better durability.
