How to use: Always use these Ninja Joint Cleaning Blades in pairs. This will ensure they work effectively to remove sealants and compressibles from control joints and create a smooth surface for resealing. Note that you need to use spacers between the blades. These spacers are made for your specific machine and application. You can buy them separately, and if you need customized ones, just call the factory. Maintenance: Keep the blades clean after each use. Check the diamond depth regularly. If it gets too shallow, it might be time to replace the blades. Also, store the blades in a dry place to prevent any damage.
