Concrete is a highly durable and widely used building material. Despite its exceptional reputation in many regards, it has its unique set of limitations. Concrete can deteriorate over time, especially when exposed to harsh conditions, frequent freeze-thaw cycles, heavy equipment traffic, and chemicals used to melt ice. Not every type of damage requires complete removal and replacement. Concrete surfaces can also be fixed with resurfacing, saving you valuable time and money.
Concrete resurfacing offers many benefits. However, it needs to be done properly and professionally to make the most of the process. Explore 5 mistakes that need to be avoided when resurfacing concrete.
Common Concrete Resurfacing Mistakes
Before you learn about the mistakes to avoid, it is important to realize why concrete resurfacing is so beneficial. Some of its key benefits are as follows:
- Application is simple and quick
- Improved value of your property
- Affordable way to restore the looks and structure
- High level of durability
The common mistakes that occur with many concrete resurfacing projects include:
1. Using Improper Tools
Many people attempt concrete resurfacing on their own and end up using the wrong tools. For one, improper tools can make it difficult to handle the task. This mostly leads to people calling on professional help to finish or rework the task.
When it comes to drilling concrete surfaces, not only will you need the right tools, but proper techniques as well. Any deviation means the tools and the concrete surfaces are likely to be damaged. The use of proper tools has a big role to play in concrete resurfacing.
Professionals will ensure that the job is completed skillfully. They will assess the surface before determining the perfect tools for the job. For example, when the surface is old and/or dense, it will require an electric hammer drill for effective and efficient results.
2. Using Improper Techniques
As mentioned above, it is common to use improper techniques along with incorrect tools for concrete resurfacing. The task requirements determine the technique to be used. Professional concrete resurfacing experts will cut the surface to the right depth. Besides, the surface will be cut at the right speed.
3. Improper Site Preparation
Concrete resurfacing requires adequate site preparation.
- The soil must have proper drainage
- The site must be stable
- Topsoil or other foreign objects need to be removed
- Multiple layers of gravel will have to be laid over the topsoil
The old concrete surface must be properly cleaned and scrubbed to remove all cement particles and dust. Make sure all liquid or oil spills are removed. The surface should be pressure washed before allowing it to dry. Before resurfacing, it is recommended to apply a concrete bonding paste.
4. Improper Curing
It is also common for people to rush with the curing process during resurfacing. This is because there is a misconception that concrete can be set within a couple of days. The fact is proper curing can take up to four weeks to complete.
Improper curing can increase the risk of cracks and make the surface unstable. If you want to paint the surface, the painting process cannot begin until the concrete has properly cured. This is even more important when the surface will be used to handle heavy traffic or heavy activities.
5. Resurfacing in Unsuitable Conditions
It is another common mistake that the resurfacing process is attempted in unsuitable conditions. It must be performed only when the temperatures are between 50°F and 60°F. Concrete resurfacing shouldn’t be done when the conditions are:
- Cold
- Hot
- Wet or humid
- Window
So, these are some of the most common mistakes to be avoided when resurfacing concrete. It is best to hire professional concrete resurfacing services to ensure the outcome is proper and your concrete surface lasts for decades.
