Custom Polyblend Non-Sanded Grout 10 lb. Natural Gray

Custom Building Products’ Polyblend Non-Sanded Grout in Natural Gray delivers a durable, polymer-modified cement formula designed for a flawless finish and consistent color. Ideal for both professionals and DIYers, this grout resists cracking, shrinking and wear, ensuring your tile joints stay pristine over time. Its non-sanded composition is gentle on highly glazed or polished tile, marble and natural stone, preventing the surface abrasion that sanded grouts can cause.

Whether you’re renovating a bathroom, updating a kitchen backsplash or tackling a commercial installation, this versatile grout accommodates joints up to 1/8 in (3 mm) and can be used indoors or out. Simply mix with water for an easy-to-apply, smooth paste that cures in 72 hours to a durable, stain-resistant finish.
