Sepp - Pumice Powder

Pumice Powder

Blend custom sanding compounds from soft volcanic stone chunks

Italian volcanic pumice ground to a fine, uniform powder that lets you control abrasive strength precisely. Mix this soft gray powder with water or oil to create custom polishing compounds matched to your specific needs, from aggressive sanding pastes for leveling rough surfaces to gentle buffing slurries for final finishing work. The volcanic structure creates consistent cutting action without the harsh scratches that harder abrasives leave behind.

Professional restorers and furniture makers rely on pumice powder for traditional French polishing techniques, where you build successive layers of shellac and carefully level between coats. The powder works equally well for preparing wood surfaces before finishing, smoothing dried paint films, or creating tooth on slick surfaces that need better adhesion. Mix thick for aggressive cutting or thin for delicate buffing, you determine the working properties.

Sepp sources authentic Italian volcanic pumice, the same material craftspeople have used for centuries of fine finishing work. Each batch maintains uniform particle size for predictable results. The powder stores indefinitely when kept dry, so you can mix fresh compounds as projects demand rather than watching premade pastes harden in their containers.
