How to Repair Exposed Aggregate Concrete How to Repair Exposed Aggregate Concrete
Aggregate concrete is a popular decorative building material used to form driveways, sidewalks or other flat surfaces, and sometimes these wear out and there’s a need to repair the exposed aggregate concrete. Having it exposed is undesirable because it makes your sidewalk or driveway uneven and bumpy. While not as effective as completely putting in a new surface, you can repair the concrete. Just follow the below mentioned guide step by step and you will master the art of repairing. But first of all you need necessary tools for the project.
Step 1 – Preparation
As the saying goes, precaution is better than cure, so take proper precaution while working on the project. Put on work gloves to protect your hands from getting injured while you work on fixing the concrete areas on your sidewalk or driveway. Lay out all the materials you need to do the project and move on to Step 2.
Step 2 – Clean the Area to be Repaired
The exposed aggregate concrete needing repairs must first be cleaned and cleared of any dirt, debris or stray pieces of grass, etc. After sweeping with a broom, you can use the hose and sprayer attachment to wash any remaining dirt off the concrete. This is important because the new concrete won’t go down properly if the area is dirty. Plus, it wouldn’t look very nice to have pieces of grass or dirt hardened into the concrete.
Step 3 – Tape off Decorative Sections
If your driveway or sidewalk has any areas of decoration that you don’t want to get ruined, use tape, such as duct or painters tape to cover it up. Only cover the areas that are absolutely necessary so you won't miss any cracks or open spaces when you are pouring the concrete.
Step 4 – Mixing up the Concrete
Mix the concrete according to the manufacturer's directions. Take your shovel and carefully pour the concrete into the areas where your exposed aggregate concrete needs to be patched. Make sure to get enough concrete into the areas that need to be repaired. After you have patched the areas, be sure to take off any tape you used to protect the decorative areas. If you don’t remember to do this, the tape will harden into the concrete and be trapped inside.
Step 5 – Evening up the Concrete Repaired Areas
Take your trowel and carefully smooth out the areas where you fixed the exposed aggregate concrete. Be sure to do this fairly quickly before the concrete starts to get hard. Only put down as much concrete as needed and do one section at a time if you have multiple sections to repair.
Step 6 – Add Finishing Touches
Wait until the concrete completely sets and is hard to the touch. This will take from several minutes to a couple of hours depending on the type of concrete you used to repair the exposed aggregate concrete areas in your driveway or sidewalk.
