Diatomaceous Earth for Paints and Coatings


Diatomaceous earth does so much for our world, including making it more beautiful. It is a common filler in paints and coatings used everywhere, enabling many projects to be completed quickly and economically, with pleasing pigments and finishes. Here’s why it works so well:

What Is Diatomaceous Earth?

Diatomaceous earth, also known as diatomite and DE, is the naturally occurring fossilized remains of diatoms—single-celled aquatic algae. It is a near-pure sedimentary deposit consisting almost entirely of silica. Diatomaceous earth has a small, complex silica framework and is valued for its:

  • Low density
  • High porosity
  • High surface area
  • Abrasiveness
  • Insulating properties
  • Chemically inert
  • Absorptive capacity
  • High brightness
  • Natural silica content

Diatomaceous Earth for Pigmenting

Diatomaceous earth extends primary pigments, adds bulk and strength, and enhances coating adhesion in paints. The uniform particle size of diatomaceous earth ensures perfect batch-to-batch matching of paint color and sheen.  Its advantages include:

  • Extends primary pigments
  • Adds bulk and strength
  • Increases permeability so paint dries quickly and uniformly
  • Enhances coating adhesion and durability
  • Chemically inert and will not react with pigments or binders that are often used is water-based organic coatings.

Diatomaceous Earth for Flattening

Diatomaceous earth fillers are also used as a flattening agent for paint. When parts of the diatoms protrude from the coating surface, they diffract light efficiently and promote a uniform sheen. By mixing different grades and qualities, you can create the finish you’re looking for, whether flat or shiny. Other advantages include:

  • Superior gloss and sheen control
  • Control of solvent release and “open time”
  • Control of polishing or burnish
  • Improved sandability
  • Scrub- and stain-resistance
  • Resistance to cracking
  • Consistent “touch-up” performance
