There are three different types of power trowel blades.
- Float Blade: Wagman float blades are designed to clip onto a finish blade bar, or a trowel arm. With the blade set in the flat position, high spots are broken down while suction and engine vibration will bring paste to the surface, all producing a uniform and level slab.
- Finish Blade: Wagman finish blades are designed to product a smooth and polished finish on concrete surfaces. They have two usable sides. After a slab has set up, trowel pitch is increased to a greater blade angle resulting in a smooth or polished finish.
- Combination Blade: Wagman combination or “Combo” blades are made from a heavier gauge steel and are designed for those who wish to use one blade for both float and finish operations. The blade has angled sides in the front and sides so that it can be used flat for floating the concrete without digging into the fresh concrete. Once the concrete starts to harden, you can pitch the blade and produce a smooth or polished finish.
