What Ardex grout is and how it compares to generic grout
Ardex grout is a brand of tile joint filler designed for residential and commercial tiling projects. It is sold in cementitious and epoxy formulations, each with distinct performance profiles. Cementitious Ardex grouts mix with water and a polymer additive to form a flexible, easy to work with joint filler that cures to a durable finish. Epoxy Ardex grouts mix with resin-based components and curing agents, producing a non porous, highly chemical resistant joint. In many bathrooms and kitchens, grout integrity is critical for resisting moisture, staining, and mold growth. Ardex products emphasize color consistency, uniform texture, and long term stain resistance, which helps DIYers achieve professional looking results.
When you compare Ardex grout to generic grout, a few differences stand out: Ardex cementitious grouts often offer a broad color palette and simpler maintenance, while Ardex epoxy options provide superior chemical resistance and moisture control. The price point typically reflects these performance aspects, with epoxy options generally costing more per square foot. For most standard indoor residential tiling, a cementitious Ardex grout is a solid choice, especially when paired with proper sealing and maintenance. For showers or heavy use areas, epoxy Ardex grout offers enhanced durability in the face of water exposure. In all cases, following manufacturer instructions for mixing, curing, and sealing yields the best long term results. According to Grout Maintenance, Ardex grout products deliver reliable performance across a range of tile installations, with emphasis on color stability and ease of maintenance.
