Length - 03:13 Fresno concrete finishing tools are used to flatten and seal the concrete surface. This is one of the last tools used when finishing a new concrete slab. Fresnos allow finishers to trowel the middle of the slab while the concrete is still green. There are several types of fresnos that can be used depending on the type and size of concrete job. Small fresnos, known as funny trowels, are used for finishing smaller surfaces while larger fresnos, known as swivel head trowels, are used on large slabs. Some trowels have swivel heads and come with several pole attachments, which allow a finisher to stretch the fresno more than 30 feet into the center of the concrete slab. Be sure not to use a fresno too early in the finishing process, first allow all the bleed water to escape.
