Introduction Bonding agents are products that help new concrete stick to old surfaces. They improve adhesion when the surface is clean, sound, and properly prepared. If you skip cleaning or misapply them, they can weaken the repair. Before choosing a method, decide whether you should repair or replace based on damage and load. Focus on […]

Introduction Concrete form release is a coating applied to forms to prevent sticking and to help control staining and color issues on the surface. Key takeaways Choose release agents carefully; improper use can stain and dull decorative color. Plan form removal timing with manufacturer instructions and local code guidance. Use recommended tools and materials from

Introduction Workability without extra water means making concrete easier to work with using techniques that don’t add more liquid. You’ll want a cohesive, workable texture that stays in place as you place and finish. Start by checking the mix for uniform consistency and using the right blend of aggregates and cement in your batch. If

Introduction Concrete washout containment is a simple setup that captures concrete slurry so it doesn’t run onto soil or into drains. This article focuses on a practical, hands-on approach you can use at home to protect your lawn and the stormwater system. It also points you toward quick links that help you navigate related notes

Introduction Concrete curing indoors means managing excess moisture so the mix dries evenly and won’t trap water that causes problems. Moisture comes from rain, groundwater, and interior activities, and your curing plan should keep the surface and near-surface air balanced. Keep the space accessible for air, avoid sealing off all drying paths, and use safe

Introduction Concrete set too slow means the concrete is taking longer to gain strength and stiffen than expected. This can happen from cold weather, too much water, high cement paste, or placement delays, and it leaves you with a soft, workable pour longer. For a DIY job, you need to check the mix label, the

Introduction Pouring new concrete next to an existing slab requires careful planning to prevent cracks. You’ll need a clean joint, proper isolation, and a compatible mix to control movement. Inspect the existing slab for movement, moisture, or coating and plan the joint and bonding approach accordingly. Always verify with the product label, manufacturer instructions, or

Introduction Backer rod sizing and proper tooling determine how deep the sealant sits and how well it resists peel-back. For DIY projects, match the rod to the joint width and choose tools that help you shape and cut the sealant cleanly. Check the joint surfaces and the manufacturer’s instructions for any minimums or recommendations. Weather

Introduction Slip resistance on sealed concrete means how much traction you get from a sealed surface to help prevent slips. Sealers are especially important around pool areas where water, soap, and wet feet are common. They also help prevent water damage and wear by sealing the pores, but you still need the right sealer for

Introduction Form leaks and fins are gaps along the slab edge caused when the formwork pulled away during the pour. These gaps can leave a rough edge and may telegraph into the finished slab. For best results, identify the gaps after the concrete cures and plan a seal or cleanup approach that uses standard concrete
