Hydra ™ American Made Grouting Sponges
Hydra Grout Sponge – Professional Hydrophilic Grout Cleaning Sponge
The HYDRA Grout Sponge is made for standard grout cleanup when you want cleaner wipes without pulling grout from joints. Its smaller cell structure helps keep joints full while producing a smoother finish, and the sponge holds up to real jobsite use without collapsing mid-cleanup.
Features & Benefits
-
Smaller cell structure: Helps keep grout joints fuller while still rinsing and releasing residue efficiently for a smoother finish.
-
Resists breakdown and collapse: Built to stay firm through extended wiping so results stay consistent from start to finish.
-
Dense, durable body: Designed for pro crews—holds up better than typical sponges during repeated wringing and wiping.
-
Rounded edges for control: Supports smoother passes and cleaner joints, especially when shaping and final detailing.
-
Two size options: Choose Medium for tighter spaces and detail work, or XL for faster coverage on large floors and walls.
Variants (Size Options)
-
Medium: 4" x 6" x 2"
-
Extra Large (XL): 7.625" x 5.5" x 2"
