Crumbling concrete can be such a frustration—especially when it is your own driveway! Not only is it unsightly but it also jeopardizes the longevity of the remaining concrete area. Many people will offer their advice on some quick, cheap fixes but when it comes to cement work it is important to be cautious and plan ahead. Having the proper tools and products will make or break your project experience and outcome.
What You Will Need
Each concrete repair is different depending on its location. Recommended products are based on whether the area is vertical or horizontal and what kind of repair is needed. Because driveways are typically horizontal, certain products excel for these types of flat surfaces. Our favorite repair mortars provide amazing results for driveway repair work:
* Lyons Patchcrete * WR Meadows Spectrum Rekote * Mapei Quickpatch
Primers or bonding agents are not necessary for every circumstance, but they are certainly recommended in order to successfully adhere the new repair mortar to the effected area. Our list of favorites include:
* Lyons P100 Primer * BASF A660 * Grace Daraweld C
An effective method to clean the crumbling area ahead of time is essential, so be sure to plan for that in advance. A nice power sprayer is a good recommendation, but not a deal-breaker.
Adequate preparation to the area is the essential first step when you begin any type of concrete repair. The products you use will only be as good as the conditions beneath them. Removing any crumbling debris is key, and while there is more than one way to do this, using a power sprayer can be a great help. Another important step is to eliminate anything that may hinder the adherence process of the mortar, such as grease, paint or oil that has previously been in contact with the area.
If you are using water to clean the area it is important to allow plenty of drying time before you apply the primer or bonding agent. If moisture is present, the primer cannot properly adhere to the surface. Be certain to follow the instructions for each chosen product, as they may vary slightly depending on brand.
To apply the primer or bonding agent, make sure to keep it well stirred. Preference in application techniques can range from brushes and brooms to rollers. The key factor is making sure you effectively work the product into the surface. Allow for the recommended drying time as provided in the product instructions; 2-3 hours is usually adequate but not all products are exactly the same so be diligent in reading and understanding the directions. It is worth noting that some products, such as Lyons P100 Primer, change opacity as the drying process is under way. Application often appears milky, but the end result will be a more clear-like coating.
Applying the repair mortar comes next and the goal is for a nice, smooth finish. It really is as simple as reading the product’s directions for correct water/mortar mixture ratio and using the recommended tools.

Why This Matters
Fixing a crumbling driveway is actually pretty simple with great products and a solid understanding of the process. Taking special care to prepare the area and using appropriate tools is the best advice anyone can offer for this type of cement work. In the end it really pays off to make these repairs in a timely manner after crumbling has started. Diligence in maintaining or replacing worn areas in concrete is crucial for overall strength and longevity of the overall cemented area.
