Obtain the perfect medium to aggressive texture with the KiwiGrip proprietary textured roller (Note: Purchase of 1L and 4L of KiwiGrip will include one 4" roller). Rollers can be rinsed, and re-used. If, during application, KiwiGrip on the roller starts to cure, rinse with water. Both 4" (recommended for most applications) and 9" (larger projects), fit standard roller handles.
