BESF Micro Stone

Micro Stone, refers to innovative decorative coatings (like micro-cement) or ultra-thin stone veneers that create natural stone looks on various surfaces, offering seamless, durable, flexible finishes for walls, floors, furniture, even wet areas, with applications ranging from smooth modern to rustic textures, providing a high-end aesthetic with easier application and maintenance than traditional stone. 

Micro Stone offers benefits for plastering by enhancing strength, reducing cracks, improving workability, and lowering costs, acting as a fine aggregate that fills voids, increases density, and improves the bond with cement, making mortar stronger, smoother, and more durable than just using river sand, especially when blended. 

Micro Stone, enhances plastering by improving strength, durability, and finish due to its fine, angular particles that bind well with cement, reducing water needs and preventing cracks; it’s also cost-effective and eco-friendly, acting as a sustainable alternative to river sand, making mortar denser, smoother, and more compact, leading to stronger, longer-lasting walls.

About BESF Micro Stone

Types & Characteristics:

  • Micro-Cement Coatings(e.g. frockcoat Micro Stone, Massif): A two-part mix (polymer + powder) applied as thin layers, creating a seamless, stone-like finish.
  • Stone Veneers(e.g. Smart Stone): Real stone, but incredibly thin (0.7-1mm), flexible, and lightweight, often cut with scissors or knives.
  • Durability:Highly resistant to impacts, abrasion, and cracking, making it suitable for high-traffic floors and wet areas like bathrooms.
  • Versatility:Bonds to concrete, wood, metal, drywall, etc., and can achieve smooth, textured, or exposed stone looks.
  • Maintenance:Easy to clean and maintain, often sealed for protection.

Key Benefits for Plastering:

  • Increased Strength & Durability:Its fine, angular particles fill voids, creating a denser, more compact mortar with higher compressive and tensile bond strength compared to plain sand.
  • Reduces Cracking:By increasing density and reducing water requirement for the same workability, it minimizes drying shrinkage, a major cause of cracks in plaster.
  • Smoother Finish:The fine texture helps achieve a smoother, more uniform surface, improving workability and leveling.
  • Better Bonding:Its particles create a strong bond with cement and sand, enhancing adhesive strength.
  • Cost-Effective:As a byproduct of quarrying, it’s often cheaper and more readily available than natural river sand, reducing overall project costs.
  • Eco-Friendly:Using stone dust (quarry dust) is a sustainable practice, utilizing a waste material from stone crushing .Creates a premium, natural stone aesthetic .Seamless finish with no grout lines .Can be applied over existing surfaces, saving demolition. Lightweight (veneer) or thin (coating) for reduced load. In essence, Micro Stone offers a modern, adaptable way to get the beauty of stone with added performance and ease of use for contemporary design projects.
  • Enhanced Strength & Durability: Its fine, angular shape promotes better interlocking with cement, increasing compressive strength, tensile bond strength, and adhesion compared to natural sand.
  • Smoother Finish: The fine texture helps create denser, more compact mortar, filling gaps and resulting in a smoother surface for plastering.
  • Reduced Cracking: Better binding and reduced water content (for the same workability) minimize drying shrinkage, which helps prevent cracks in the finished plaster.
  • Cost-Effective: Often cheaper and more readily available than river sand, making it a budget-friendly choice for construction.
  • Eco-Friendly: Utilizes a byproduct of stone crushing, reducing quarry waste and lessening the environmental impact of sand mining from rivers.
  • Improved Workability: When mixed correctly, it can reduce water demand while maintaining good workability, improving overall mortar performance
 
 

How to Use It:

  • Mix with Sand:It’s typically blended with building sand (fine aggregate) and cement for wall plastering.
  • Fine Screening:Ensure the dust is fine (0-4mm range) and free of large stones or excessive silt, as high silt content weakens plaster.
  • Improved Mix:Studies show that replacing some sand with stone dust can reduce water demand while boosting mechanical properties, leading to better performance.
 

How it Works in Plaster Mix:

  • Filler & Binder: Acts as a fine filler that reduces air voids and creates a denser matrix with cement and sand, leading to stronger bonding.
  • Particle Shape: The crushed, angular particles provide more surface area for cement to grip onto compared to smooth river sand, enhancing cohesion. 
 

In essence, using stone dust in plaster creates a stronger, smoother, and more durable wall finish at a lower cost, all while being a greener building material.

 

Common Applications:

  • Interiors:Walls, floors, ceilings, kitchen countertops, furniture, bathroom tiles.
  • Exteriors:Walls, potentially pool areas (with proper sealing).
