CALCIUM CARBONATE BLASTING MEDIA

Calcium Carbonate

Gentle, Salt-Free & Architect-Approved Blasting Media

We offer Calcium Carbonate abrasive blasting media in two forms: Ground Calcium Carbonate & Pearl Blast, (or Oolitic Calcium Carbonate). This versatile, soft media is ideal for cleaning and restoring stone & masonry. Its odorless, safe nature ensures it won’t trigger efflorescence or harm delicate surfaces, making it perfect for removing carbon deposits, atmospheric pollution and soot from materials like granite, marble, masonry, brick & limestone.

Our Calcium Carbonate abrasive blasting media is landscape and operator-friendly, rinsing quickly while proving effective without damaging the surface. Its chemical compatibility with building materials earns it the distinction of being “architect-approved,” making it a top choice for restoration and surface prep.

LEARN THE DIFFERENCE!

Oolitic Calcium Carbonate is one of the world’s purest forms of the ocean’s naturally precipitated calcium carbonate. It is renewable, biogenic, sustainably sourced, and has a different morphological structure than traditional ground calcium carbonate.

It has egg-shaped crystals which form during natural precipitation events called ‘whitings.’  It is tasteless, odorless, and most importantly non-polluting.
