Marshalltown GB690 Seamless Grout Bag 12x24

Product Description

The MARSHALLTOWN GB690 is a seamless grout bag measuring 12 inches by 24 inches, designed for holding and dispensing grout or mortar during tile, masonry, and stonework applications. The bag features a blue molded tip that can be cut to the desired opening size, giving the installer direct control over flow and bead width. The seamless construction reduces the risk of blowouts under pressure, making it a reliable choice for controlled dispensing in tight joints and grout lines. Tile setters, masons, and masonry contractors reach for this tool when precision placement of grout or mortar is required without the mess of a trowel.

The GB690 is suited for residential and light commercial tile and masonry work. It performs well in applications such as grouting brick joints, filling mortar joints in stonework, and applying grout in decorative tile installations where neatness and control matter. The adjustable tip opening allows the same bag to serve multiple joint widths across a single job, reducing the need to switch tools mid-task.

Key Features

• Seamless bag construction reduces pressure failure points during dispensing
• Blue molded tip can be cut to match the required joint or opening size
• 12-inch by 24-inch body accommodates a working volume of grout or mortar
• Suitable for grout, mortar, and similar cementitious materials
• Reusable design supports repeated use across multiple applications

Compatibility

Designed as a general-purpose grout and mortar dispensing bag compatible with standard cementitious grouts and mortars used in tile, brick, and masonry installations.

Installation Notes

Tile setters and masons should cut the molded tip incrementally, removing small amounts at a time until the desired opening size is achieved — overcutting cannot be reversed. Fill the bag no more than two-thirds full to maintain manageable pressure and reduce hand fatigue during dispensing. Clean the bag thoroughly after each use if it is to be reused, as hardened grout or mortar will compromise the tip and seam areas. No power tools or specialized codes apply to hand-dispensing equipment of this type.
