Mapei Flexcolor 3D Ready To Use Grout

Mapei Flexcolor 3D Ready-to-Use Translucent Grout, 1/2 Gallon

Flexcolor 3D is a professional-grade, ready-to-use translucent grout with an "iridescent effect" finish, offered in 10 designer colors. Unlike a standard opaque grout, it reflects and refracts light, letting the grout transition in color to complement the surrounding tile — the translucent effect is most noticeable in Crystal Moon (#5201), while the other nine colors lean more iridescent.

Formulated for interior commercial and residential installations of porcelain, ceramic, glass, and natural-stone tile — including granite, travertine, slate, marble, and polished marble — plus quarry tile, cement-based terrazzo, and groutable LVT/LVP. Suitable for intermittent wet conditions like shower floors, tub surrounds, and shower walls.

Dense surface structure resists water-based stains and requires no sealing. Recycled glass-bead aggregate delivers color consistency, easy cleanability, and improved workability, curing naturally with no mixing required — about 65% faster to install than traditional powder grout. Green Squared Certified and LBC Red List Free.

Will every color look translucent? Crystal Moon (#5201) shows the clearest translucent effect. The other nine colors lean more iridescent — reflecting light rather than letting it pass through.

Can I use this in a shower? Yes — it's approved for intermittent wet conditions like shower floors, tub surrounds, and shower walls.

Does it need to be sealed? No — its dense surface structure resists water-based stains without sealing.

Why does a milky film sometimes show up after grouting? Under certain conditions a milky film can appear on the surface — it typically dissipates 20–30 minutes after washing during install.
