RTC Block Microfiber Pro Sponge

RTC Block Microfiber Pro Sponge: Two Sided Microfiber Finishing Sponge

The RTC Block Microfiber Pro Sponge is a professional-grade dual-sided microfiber finishing sponge designed for final grout cleanup, haze removal, and tile polishing applications. Engineered for tile installers and finishing professionals, this proprietary microfiber sponge delivers efficient cleaning performance while helping maintain full grout joints and clean tile surfaces.

Its innovative two-sided microfiber construction provides double the working surface compared to traditional grout sponges, reducing rinse frequency and increasing productivity on the jobsite. The high-contact microfiber material captures grout haze, residue, and fine particles effectively while polishing tile surfaces for a cleaner final finish.

The sponge’s square-edge design allows installers to glide smoothly across grout joints without pulling material from the joints, helping maintain consistent grout lines and cleaner corners. Its block-style shape provides comfortable handling, improved control, and maximum surface contact during wiping and finishing.

Ideal for use with most cement-based grouts, the Block MF Pro performs exceptionally well on ceramic tile, porcelain tile, natural stone, and other hard surface installations. It is not recommended for use with epoxy grout systems.

In addition to grout cleanup, the RTC Block Microfiber Pro Sponge also functions as an excellent general-purpose cleaning sponge for tile surfaces, countertops, backsplashes, and finishing work.
