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 ‘Cool Deck’ Coatings: Heat Reduction Claims and What Prep Actually Controls Delamination

Introduction Cool deck coatings are heat-reflective surface finishes applied to concrete to reduce surface temperatures and glare. But whether they last depends mainly on how the base concrete is prepared and bonded. This article cuts through the hype and tells you what prep actually controls delamination. Delamination happens when the coating separates from the concrete […]

Stamped Concrete at DIY Scale: Release Agents, Joint Planning, and Sealing Without Slippery Film

Introduction Stamped concrete at a DIY scale is about using release agents, planning joints, and sealing so the finish isn’t slick. Keep expectations simple: choose a release agent you can apply evenly, map where joints go before stamping, and select a sealer that reduces glare without creating a slippery film. Start with a clear plan,

Preventing Cracks Around Slab Penetrations: Pipe Sleeves, Bond Breakers, and Joint Layout

Introduction Cracks around slab penetrations happen when the concrete around pipes or openings isn’t managed during pour. Key takeaways Use pipe sleeves fully encased in concrete, with proper clearance for movement. Apply bond breakers on form faces and sleeves to minimize three-sided adhesion. Plan joint layout early to align joints with penetrations and expected movement.

Salt-and-Pepper Polished Concrete: Achieving a Consistent Exposure Without Over-Grinding Edges

Introduction Salt-and-pepper polished concrete is a finish created by exposing a small, random mix of aggregate to produce a speckled, even look. The goal is to achieve a consistent exposure across the slab without carving too deep at edges. This approach keeps the surface looking uniform and practical for DIY applications. Edge finishing matters because
