Finishing the Concrete: Screeding, Floating, Jointing, Troweling, Broom Finishing, and the Slump Test

In this episode I walk you through everything the CSLB B General exam expects you to know about finishing concrete — one of the most detail-heavy and frequently tested topics in the entire exam. This is not surface-level stuff. I go deep on every step of the finishing process, the exact code numbers you need to memorize, and most importantly the WHY behind every rule so the information actually sticks when you sit down to test.

I cover the complete concrete finishing sequence from start to finish: screeding, bull floating, edging, jointing, troweling, and broom finishing. I explain the joint spacing formula, the joint depth rule, the three types of joints, when to cut joints in hot weather, and the difference between control joints, isolation joints, and construction joints. I also break down the slump test in full — the Abrams cone, the three types of slump results, and what each result tells you about your concrete batch. Every number, every code requirement, and every rule is explained with the real-world context and history that makes it memorable.
