Concrete

Concrete is where I keep my step-by-step guides for planning, pouring, and finishing concrete projects.

Topics include base prep, forms, reinforcement, thickness, mixing and placing, finishing, curing, sealing, and long-term durability. I also cover troubleshooting—what to do when concrete cracks, scales, dusts, or cures unevenly.

If you’re new to concrete, start with the planning and prep articles. They prevent most of the expensive mistakes.

Concrete Bleeding vs Segregation: How to Spot Each and What to Do

Introduction Concrete bleeding is water rising to the surface of fresh concrete as the mix sets. Segregation is when heavier components separate, causing uneven texture or coverage. Both can affect finish and long‑term durability if not spotted and managed early. Bleeding shows as a wet sheen on the surface and may leave a thin film […]

GFRC Countertops: Face Coat vs Backer Coat (and How to Avoid Pinholes)

Introduction GFRC countertops use a thin face coat over a cement-rich backer to give the look of stone while keeping strength and cost in check. The face coat forms the visible surface and texture, while the backer provides depth and rigidity. In DIY practice, you’ll mix, pour, and cure them in layers, paying attention to

Concrete Maturity Method for DIY Pours: Estimate Strength by Tracking Temperature

Introduction The concrete maturity method is a practical way to estimate concrete strength by tracking temperature over time. In DIY pours, you monitor concrete temperature as it cures and use that data to infer when it reaches sufficient strength. Always follow product labels and local rules, and understand that this method is a guide, not

Concrete That Turns Dark When Wet: Diagnosing porosity and finishing issues

Introduction Concrete that turns dark when wet indicates moisture affecting the surface, usually tied to porosity and finishing issues. In plain DIY terms, that color change is your cue that water is soaking in or being held near the finish. It’s a practical clue to start diagnosing what went wrong during pour, finishing, or sealing.

Lime Leaching on Concrete Features: Why it happens and how to reduce it

Introduction Lime leaching on concrete features is the migration of lime compounds to the surface, leaving white deposits. This happens when water moves through the concrete and dissolves soluble lime, then brings it up as it evaporates. For DIY work, you can slow it by careful curing, avoiding long wet periods, and following manufacturer guidance
