What happens in this clip
Using a chisel and a hammer, carefully chip away any raised or loose concrete on the steps, especially along the edges. After removing the larger pieces, use a brush to sweep debris from crevices and corners. The most crucial step is to grind the concrete surface. Use an angle grinder equipped with a 4.5-inch grinder wheel or flap disc to remove all remaining loose and peeling paint, as well as to feather any lifting edges. For safety, wear a particulate respirator, safety glasses, and ideally a face shield. The grinder shield was removed to access tight corners, but this should be done with extreme caution. After grinding, sweep up all debris thoroughly with a broom and use a shop vac to remove fine dust from all edges and hard-to-reach areas.
Goal: Remove old paint and loose concrete, and create a smooth, clean surface.

About the full video
This project details the step-by-step process of restoring concrete front steps by cleaning, grinding, patching imperfections, and applying fresh paint to achieve a clean and improved look.
Step 2 of 6: Prepare the Surface
Inspect the steps for any cracks, holes, or loose boards. For concrete steps, fill cracks and holes with a concrete patching compound, following the manufacturer's instructions. For wooden steps, replace any rotten or damaged boards and secure any loose ones. Sand down any rough or splintered areas using medium-grit sandpaper (around 80-grit) to create a smooth surface. If there is old, peeling paint, scrape it away with a paint scraper and sand the edges smooth. For a smoother finish, especially on concrete, consider using a concrete degreaser if there are oil stains, and then rinse thoroughly.

Questions about Anti-Slip Steps
Do I absolutely need a high-powered pressure washer for cleaning, or can I just scrub the steps manually?
While manual scrubbing with the Shurhold 6 in. Marine Mate Stiff Brush and Klean-Strip Liquid Concrete Degreaser is an option, a pressure washer like the Westinghouse WPX 3800 psi significantly enhances cleaning efficiency. It ensures the removal of embedded dirt, loose paint, and grime, creating a superior surface for the DAICH Textured Bonding Primer and BEHR PREMIUM anti-slip paint to adhere to, which is crucial for durability.
What are the most important safety precautions to take when using the pressure washer and chemical degreaser?
Always wear appropriate personal protective equipment (PPE), including safety glasses, chemical-resistant gloves, and closed-toe shoes when operating the Westinghouse pressure washer or handling Klean-Strip Liquid Concrete Degreaser. Ensure adequate ventilation, especially in basement areas, and keep children and pets away from the work zone during chemical application and pressure washing to prevent accidental exposure.
Why does a 'beginner' project like anti-slip steps take two full days, and what factors might extend this timeframe?
The 2-day estimate accounts for crucial drying and curing times for each layer: degreasing, patching (with Quikrete or PC-Lumber Putty), priming, and applying two coats of BEHR PREMIUM anti-slip paint. High humidity, low temperatures, or extensive repairs that require longer setting times for patching compounds can all extend the project duration. Rushing these steps will compromise the final finish and durability.
What's the most common mistake DIYers make when applying anti-slip paint, and how can I avoid it?
The most common mistake is inadequate surface preparation, which leads to poor adhesion and premature peeling of the paint. To avoid this, thoroughly clean the steps with Klean-Strip Degreaser, pressure wash all debris, fill and sand all cracks and imperfections using Quikrete and PC-Lumber Putty, and apply DAICH Bonding Primer as directed. A clean, smooth, and primed surface is key to a long-lasting finish.
Can I use standard outdoor patio paint instead of the specific BEHR PREMIUM anti-slip paint listed?
While you could technically use other outdoor paints, the specified BEHR PREMIUM 1 gal. #420C-2 Textured Low-Lustre Enamel is designed with integrated anti-slip properties, significantly enhancing safety. Standard paints may become slick when wet or icy, defeating the primary purpose of this project. For optimal safety and durability, using the recommended anti-slip product is highly advised.
When should I use Quikrete Concrete Patching Compound versus PC-Lumber Putty Epoxy for repairs?
Use Quikrete 1 Qt. Concrete Patching Compound for larger cracks, spalls, and uneven areas in concrete steps, as it's formulated for robust concrete repair. PC Products 2 oz. PC-Lumber Putty Epoxy is best suited for smaller chips, divots, or repairing wooden step components where strong adhesion and sandability are required. Always ensure patches are fully cured and sanded smooth before priming.
