This is a set of 3. It is being sold with various spare backer rods. The advantage of having spare backer rods is significant, as you can instantly replace a backer rod that becomes unusable and immediately resume work. ✅ We also have many other easy-to-use, immediately useful spatulas for sale, so please take a look! ✅ ↓↓↓ #TommyCaulkingSpatula These are spatulas used frequently in construction. Please use them appropriately for different situations. These spatulas are great for exterior walls, window frames, siding, ALC, RC, various joint seals, and all types of sealing work in new construction and renovations. Of course, they are also suitable for interior work. They can be used anywhere. The spatulas in this set can be used for the entire process, so I think they can handle a wide range of applications. See images 6-9 for examples of how to use the belly and tip of the spatula. The round spatula has an orange finish backer rod (5mm) attached. It is durable because it is scratch-resistant, and the medium hardness makes it easy to finish. It is moderately soft, so it conforms to uneven surfaces and spreads the sealant. The finish backer rod is tapered, so there is no dragging of the sealant at the beginning of the application, and the caulking is exceptionally clean. Because the backer rod is free of splinters, no lines appear in the sealant during finishing, resulting in a beautiful finish. The square spatula has an orange 7mm backer rod. Tapered on the top and sides. ✅ #TommyCaulkingSpatula ✅ ← This is a list of my immediately useful spatula products. This is a highly recommended item. Thank you.
