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.

How to Patch an Over-Drilled Anchor Hole in Concrete Without Losing Strength

Introduction Patching an over-drilled anchor hole in concrete without losing strength means cleaning the hole, choosing a compatible filler or epoxy, and installing the repaired anchor so the load transfers into sound material. This is a hands-on fix: identify whether the hole is shallow, deep, or into cracked concrete and pick a material rated for […]

Edge Distance Rules for Concrete Anchors: Practical Layout to Avoid Blowouts

Introduction Edge distance rules for concrete anchors mean keeping anchors far enough from slab edges, joints, and other anchors so the concrete can carry the load without cracking or breaking out. In practice that means planning layout with the anchor type, concrete strength, edge quality, and load direction in mind. Check the anchor manufacturer instructions

Setting Epoxy Anchors in Damp Concrete: When It Works and When It’s a Hard No

Introduction Epoxy anchors can work in damp concrete, but whether they do depends on the product and the site conditions. Some epoxies tolerate dampness or damp-to-wet surfaces, while others require dry holes—check the manufacturer instructions and product label before you start. On the jobsite that means choosing the right epoxy cartridge for moisture, cleaning and

Vapor Barriers Under Slabs: Thickness, Seams, and How to Patch After Plumbing Cuts

Introduction A vapor barrier under a slab is a continuous layer of material placed on the subbase to limit moisture movement into the concrete. For DIY installs that means picking a durable sheet, checking the manufacturer label for thickness and puncture resistance, and planning how seams and penetrations will be sealed. Think practical: roll it

Concrete Moisture Meter vs Plastic Sheet Test: What Each Tells You Before Coating

Introduction Concrete moisture meters and the plastic sheet test are two different ways to check slab moisture before you coat it; a meter gives a readout from the surface or near-surface while the plastic sheet looks for moisture vapor trapped under a taped film. Think of the meter as a quick diagnostic and the plastic

Concrete Etch Alternatives: When Degreasing and Profiling Beat Acid Washing

Introduction Concrete etch alternatives are practical cleaning and mechanical methods—like degreasing and surface profiling—that replace acid washing when you need safer, more controlled prep. As a DIYer, think of degreasing to remove oils and contaminants and of profiling (grinding, shot blasting, or scarifying) to roughen the slab so coatings will stick; check product labels and

Concrete Dyes vs Stains: UV Fade Reality and Best Uses Indoors vs Out

Introduction Concrete dyes are colorants that penetrate or bind to the surface for vivid, often translucent color, while stains are chemical or pigment treatments that change color through a reaction or surface coating; pick the product by reading the label and manufacturer instructions for your exact material. In plain jobsite terms: dyes usually give brighter,

Concrete Stain Blotchiness: Why Porosity Changes and How to Even It Out

Introduction Concrete stain blotchiness is when the color looks uneven because the slab soaks up stain at different rates. It happens because porosity varies across the surface from finishing, curing, contaminants, or patchwork. You can reduce it by cleaning, profiling, and using appropriate primers or application methods—check product labels and manufacturer instructions for compatibility. For

Self-Leveling Overlay Over Concrete: Primer Steps That Stop Debonding

Introduction Self-leveling overlay over concrete is a pourable cement-based or polymer-modified material that evens a slab, and the right primer and prep are what stop it from debonding. Before you mix anything, clean and mechanically profile the slab, repair cracks and holes, and read the overlay and primer instructions for recommended substrates and pot life.
