Disposable Putty Knife for Sealant Application The HYDRO-BLOK® Putty Knife is a disposable application tool designed for spreading, smoothing, and finishing sealants during waterproofing and tile installation projects. Its rigid ABS plastic construction provides consistent control when working sealant into seams, joints, and transition areas. 3" Blade for Controlled Sealant Distribution The 3" blade width allows sealant to be distributed evenly while helping create smooth, consistent finishes across waterproofing transitions and other sealing applications. The rigid blade maintains its shape during use for improved application control. Compatible with Waterproofing and Tile Installation Commonly used with HYDRO-BLOK® Joint Sealant, this disposable putty knife is also suitable for use with other compatible sealants. It is ideal for waterproofing systems, tile installations, and general sealing applications where clean, controlled sealant application is required.
