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.

Tapcon Screws in Concrete: When They Strip and How to Get Real Holding Power

Introduction Tapcon screws are concrete screws designed to bite into hardened concrete. They tend to strip when the hole is too large or when the screw is driven without a clean, bored hole and straight alignment. That makes it hard to hold heavy fixtures and requires careful installation. To get real holding power, start with […]

Fiber + Wire Mesh Together: When It’s Redundant and When It Helps

Introduction Fiber + wire mesh together is a reinforced concrete setup where fibers help control cracking and mesh provides added structural distribution. Redundancy can mean extra fibers or extra mesh ends up overlapping; watch for overcomplicating the pour. Combining fiber with mesh can help in slabs with control joints or poor soil, but it can

Coating Over Damp Wood Near Concrete: Why Blisters Form and Better Breathable Systems

Introduction Blisters form when moisture underneath the coating pushes through and splits the film over damp wood near concrete. You’ll see raised bubbles or pockets as the coating tries to cure in a wet, alkaline environment. Work is risky if you skip drying and proper surface prep. Look for breathable coating options and follow proper

How to Tell If Concrete Is Too Smooth to Coat: Simple Adhesion Checks Before You Prime

Introduction Too smooth concrete resists adhesion and can fail after priming. This article shows simple checks to decide if the surface needs profiling. Roughening helps primers bite into the surface and create a lasting bond. Start with cleaning, then roughen the area using a grinder, wire brush, or sanding pad and clean away dust. Do

Concrete Surface Prep for Coatings: How to Hit the Right Profile Without Over-Grinding

Introduction A proper surface profile is the texture and cleanliness of concrete that coatings need to bond. Before applying anything, clean the floor thoroughly to remove oils, dust, and contaminants. Profiling options like shot blasting or diamond grinding are used to create the key texture; choose based on the concrete and the coating. After blasting
