PUMICE APPLICATIONS AT A GLANCE
(CLICKABLE MENU)

Concrete

Concrete: Lightweight Pumice Aggregate and Sand

Lightweight Concrete Aggregate: Lightweight pumice aggregate for craft-type precast concrete projects—including statuary, containers, pavers—where a smaller aggregate size (3/8 to 1/8-inch stones with some fines/sand) is desirable.

Lightweight Pumice Sand: Pumice sand + (includes) tiny 1/8-inch stones. Use in lighweight mortars and as an additive to the craft aggregate when more sand content is desired. Also used for lightweight insulative plasters.

Concrete Canoe: National Concrete Canoe Competition (NCCC) Teams: We field scores of inquiries each NCCC season about sourcing our lightweight pumice aggregate and natural pozzolans. Here’s what you need.

Concrete: Performance-Enhancing Pumice Pozzolan

Densifier325™ Standard Pozz: A highly-effective natural pozzolan for precast concrete products as well as formed-and-cast concrete construction like walls, piers and foundations. Used in shotcretes, cementitious grouts, plasters, mortars. Densifier325™ is a must in regions with reactive aggregates that cause ASR and in locations with high-sulfate soils or in applications subject to sulfate and/or chloride attacks. Also effective in high abrasive and freeze-thaw environments.

UltraPozz: An ultrafine (3 micron) pozzolan for high-performance precast concrete products, especially glass fiber reinforced concrete (GFRC) panels and other architectural accent pieces. Also used in ultrafine cementitious grout formulations.

Abrasives

Abrasives: Sand Blast Media

Sand Blast Grit: Available in four grades from our standard Sand Blast Heavies to fine. Pumice sand provides a less aggressive, low-etch bite to clean and prepare surfaces of all types, especially softer surfaces and those with cast, carved or sculpted details. Also great for small, detailed parts.

Exfoliant

Exfoliant: Exfoliating Powder for Scrubs, Soaps, Creams

Magma™ is a fine pumice powder that pairs with your favorite beauty product, giving you full control over the exfoliating effect—just add less or more depending on skin type and the task at hand.

Horticulture

Soil Amendment and Conditioner: SoilRox™

Amend the physical profile of poorly-structured native soils—especially heavy clay soils—opening up pore spaces to greatly improve drainage and aeration (gas exchange) in the root zone. Condition and enhance soil function by improving the capture, hold and time-release curve of moisture and nutrients back to the roots.

Soilless Grow Media: Ponics Stone™

Ultra-efficiency soilless grow systems demand high-performance grow media. Ponics Stone™ delivers in the key areas of stability, nutrient holding capacity, gas exchange, drainage, weight, media particle size, crop balance and media life.

Livestock and Pets

Livestock and Pets: Dust Bathing Critters

ChillDust™ is a pure and natural bathing dust that provides your chinchillas and degus with both the means to keep that lush fur coat in primo condition and the flipping, spinning, effusive joy that comes with it.

Livestock and Pets: Chew Stones

Chewlas™ are natural pumice stones that provide your Rodentia-order (gnawing) pet with the ideal abrading surface to keep claws and teeth naturally worn down to a healthy length. Chewlas also make great in-cage play toys to push around, and providing a chew stone can save the gnawing wear and tear on other parts of the habitat.

Texturizer

Texturizer: for Primers and Paints and Non-Skid Coatings

Dimension Grit™ Baby Bite is an in-suspension grip agent for giving tooth to primers that prepare gypsum wall board surfaces to take fine interior plasters. Also for paints where a subtle texture is desired while also serving as a functional filler/extender.

Dimension Grit™ Rough Bite is an in-suspension grip agent for primers that prepare gypsum wall board surfaces to take thicker interior plasters. Also for paints and floor coatings where a roughened, traction-worthy texture is desired.

Dimension Grit™ Monster Bite is an in-suspension grip agent for floor and deck coatings.

Functional Filler and Extender

Functional Filler: Non-Crystalline Silica (NCS)

Hess NCS: Micronized pumice (amorphous aluminum silicate) grades that are non-hazardous (crystalline silica free to the detectable limit of .05%), inert, near white, with a pH of 7.2. Hess NCS grades work as performance functional fillers and extenders for architectural paints and stains, industrial coatings, rubber compounds, plastics/fiberglass compounds, expoxies, and caulks. Available in five grades ranging from 3 microns to 12 microns (average particle size).

Attenuator

Attenuator: Explosive Blast Mitigating Material

Blast Mitigator™ is a lightweight, non-reactive, non-crystalline energy-attenuating natural material for a variety of blast mitigation applications. last Mitigator™ can be used as a loose fill in a double-walled space or combined with a resin binder for shaped applications.
