Bostik Dimension Grout utilizes tiny glass beads and a translucent urethane binder, allowing light to reflect like and enhance the look of your tile. Detracting from the tiles appearance, other grouts often contain light-absorbing materials. Bostiks unique feature allows for unlimited design possibilities by creating a stunning three-dimensional and reflective appearance. Colors shown online are not guaranteed and are for reference only.
