Grout lines narrower than 1/8 inch demand a formula without sand particles that could jam between closely-spaced tiles. This non-sanded grout flows smoothly into tight gaps, settling completely without creating voids or air pockets that compromise durability. The water-based, non-cement formula eliminates the dust and caustic handling concerns of traditional grout while maintaining the structural integrity your mosaic needs.

White base accepts standard acrylic paints or colorants, letting you match grout precisely to your tile palette or create intentional contrast. Mix small batches to test colors before committing to larger areas. The formula stays workable long enough to spread and tool properly without racing against flash-drying, yet firms up reliably once applied.

Each 8-ounce jar covers approximately 4-6 square feet depending on tile thickness and spacing, enough for substantial tabletops or multiple smaller pieces. Clean tools and surfaces with water while the grout remains wet; once cured, this formula resists moisture and normal household cleaning. Jewelry makers working with micro mosaics and artists creating fine-detailed murals both rely on this grout when precision placement demands a filler that won't fight against tight tolerances.
