Many homeowners and businesses choose to install artificial grass on top of concrete to improve their outdoor areas.
Installation of this type of grass provides a low-maintenance alternative to natural grass, making it suitable for patios, decks, and balconies alike. Artificial turf is typically used to replace a lawn that already exists.
However, it can be a convenient method of resurfacing old and worn concrete pathways. The advantages of artificial grass include its low maintenance, the absence of dirt, and its safety for children and pets.
To help you get started, this article will provide you with the information you need and most importantly will also explain how to install artificial grass on concrete.

Tips to Consider Before Installing Artificial Grass Onto Concrete
To prepare the floor and the materials for the installation of artificial grass, the following tips can be helpful:
- Preparation of the surface: Ensure that the surface on which the artificial grass is about to be installed is clean, flat, and free of debris before you begin the installation process.
- Measure the area: To determine how much artificial grass is required, you need to measure the area where the artificial grass is planned to be installed and use this measurement to determine how much artificial grass will be required.
- Lay a weed barrier: Make sure that the area you are going to plant artificial grass on is covered with a weed barrier to prevent weeds from growing through the artificial grass.
- Install a drainage layer: To ensure proper drainage, it is important to install a drainage layer (such as crushed stone or gravel) over the weed barrier to ensure proper drainage.
- Install a shock pad: For areas of high traffic, installing a shock pad can provide extra cushioning and support.
- Rake and brush the artificial grass: Rake and brush the artificial grass: Use a stiff-bristled rake or a power broom to evenly distribute the infill and to make the artificial grass stand up.
How to Install Artificial Grass on Concrete?
Step 1: Supplies Needed
The first step in the installation process is to gather the tools that are required for the job.
- Artificial grass
- Artificial grass underlay
- Stanley knife
- Stiff brush
- Tape measure
- Artificial grass glue
Step 2: Take measurements
When you plan to lay artificial grass on the concrete surface yourself, it is important that you first determine how much grass you will need to cover the area adequately. It is necessary so that artificial grass can be laid properly. It is therefore crucial that you measure the area that will be filled with artificial grass before you start installing it.
Step 3: Preparation of the surface
Get rid of any debris or dirt that has accumulated on the concrete surface. To keep the surface of the concrete weed free, a weed barrier needs to be installed.
If artificial grass is not designed to have an effective drainage system, it will end up being a large sponge that drips on everything it touches. To allow water to reach the permeable layers below the concrete, use a masonry drill bit to drill holes into the concrete surface and fill them with large pebbles to fill the holes.
A layer of crushed stone or gravel should be spread over the weed barrier to keep it in place. By doing this, you will be helping with drainage and providing a stable base for artificial grass as well.
Step 4: Lay the artificial grass foam underlayment
Underlay is always recommended when installing artificial grass on concrete. However, depending on what you want to use it for, it may be an unnecessary expense.
Surfaces with slight imperfections will be leveled with a foam underlay. Whether you are going to use the area for children or play sports on it, an underlay is a must. The corner farthest from your finished position should always be the starting point.
Make sure the foam is in place before gluing. A common mistake is to glue the underlay to the surface and then realize it is wrong. Make sure everything is laid out before cutting and gluing in place or you may have to make costly changes.
Cut the foam flush with the inside and outside edges of the area using scissors or a Stanley knife. You can use duct tape to hold the pieces together if they move.
Strong adhesives are needed to bond the foam to the ground. As a result, plenty of drainage space was provided.
Step 5: Install artificial grass on the concrete surface
Roll out the artificial grass over the underlay until it is completely covered. To adjust the artificial grass for the space, you will need to trim the edges with a utility knife. By using landscaping adhesive, you will be able to secure the artificial grass to the concrete surface.
To prevent the edges from being cut, it is recommended that they be glued instead. As a general rule, if your fake grass is going to fit flush with an edge, it is advisable to glue this area first. Then, it is advisable to move forward from there.
As for the rest, you can cut it into shapes as you wish. In the end, after you are sure that everything fits together, it is time for you to cut it out.
Step 6: Brush and sand the surface
Lastly, you should brush the artificial grass to make sure the fibers stand up and give the lawn a more natural appearance. You can add a layer of infill (usually sand) over the artificial grass to help keep the fibers upright and make the lawn look and feel more natural.
Why is it Difficult to Install Artificial Grass onto Existing Concrete?
It can be difficult to install artificial grass over existing concrete for a variety of reasons:
- The unevenness of the surface: In many cases, the concrete surface will have cracks, chips, or other imperfections that can make it difficult for artificial grass to achieve a smooth even surface.
- Insufficiencies in adhesion: Even though concrete is a smooth, non-porous surface, it can be difficult for artificial grass to achieve a secure bond on top of it since concrete is a smooth, non-porous surface. Eventually, this can cause artificial grass to shift or become loose as a result of these factors.
- The issue of weight: It is a fact that concrete is a heavy material. Therefore, putting artificial grass on top of concrete could put a great deal of strain on the concrete structure that already exists.
To overcome these difficulties, it is important to use an installation method that is designed specifically for use on concrete, such as using an adhesive designed to be used on concrete, or a self-leveling compound that can be used to create an even surface for artificial grass.
Additionally, artificial grass may need to be installed with a drainage layer under it if drainage is a problem. Consult a professional if you are installing artificial grass on existing concrete.
What Glue to Use for Artificial Grass on Concrete?
Installation of artificial grass on concrete can be done using several types of adhesives. Construction adhesive, double-sided tape, and turf adhesive are some of the most popular options that are available to you.
To bond artificial grass to concrete, you can use a construction adhesive that is strong, heavy-duty, and can be used to bind artificial grass to concrete.
It is also possible to attach the grass using double-sided tape, which is a more temporary solution but can also be successful at holding it in place.
Turf adhesive is a special adhesive that is designed specifically for artificial turf. It can provide a strong bond between grass and concrete surfaces by providing a high level of adhesion.
Ultimately, your decision on which adhesive to use will be based on the specific needs of your project. Several factors need to be considered here, such as the weight of the artificial grass, the predicted foot traffic, and the desired durability.
Pros and Cons of Putting Artificial Grass on a Concrete Floor
- Artificial grass requires very little maintenance in contrast to natural grass, which must be watered, mowed, and fertilized regularly.
- Heavy traffic and frequent use do not adversely affect the durability of artificial grass.
- Dirt and debris can be easily removed by sweeping or hosing off artificial grass.
- Artificial grass is versatile enough to be used both indoors and outdoors, such as on patios, decks, and in indoor sports facilities.
- Artificial grass can help reduce noise on concrete surfaces, but if the surface is not prepared properly, it can amplify it.
- It can be expensive to install artificial grass on a floor, especially if it needs to be prepared or leveled beforehand.
- The drainage capabilities of artificial grass are limited, which can lead to standing water and other drainage problems.
- During hot weather, artificial grass can retain heat and make walking and playing uncomfortable.
- Artificial grass lacks the same feeling as natural grass, making it less comfortable to walk on or play on.
- The lifespan of artificial grass is limited, and it needs to be replaced after a certain period.
How to Clean the Concrete Floor Before Starting Installation?
Before installing artificial grass, clean a concrete floor by removing debris and loose material. Clean it with a pressure washer in a low-pressure setting. Allow it to dry completely. Then, use a degreaser or concrete cleaner to remove any stains, oil, or residues.
Apply a concrete primer or adhesive before laying the artificial grass to repair any cracks or holes. Before installing artificial grass, ensure the floor is level, clean, and dry, and follow instructions. If you are unsure, consult a professional.
Can I Just Lay Artificial Grass on Concrete?
Yes, it is possible, but there are a few things to keep in mind before taking the plunge.
First, the concrete surface must be level, clean, and dry. Before installing artificial grass, repair any cracks, holes, or uneven surfaces.
Secondly, a concrete primer or adhesive should be used to keep artificial grass in the place.
Thirdly, if you are installing artificial grass in an area where there will be a lot of foot traffic or regular use, consider choosing higher-quality artificial grass. Choosing higher-quality artificial grass or adding padding underneath may be needed to protect the concrete surface.
Finally, make sure you follow the manufacturer’s instructions and recommendations when installing artificial grass.
Do you Need Underlay for Artificial Grass on Concrete?
Underlays aren’t strictly necessary when installing artificial grass on concrete, but they can have several benefits. An underlay can give artificial grass a softer surface to sit on, making it more comfortable to walk and play on.
Additionally, an underlay can increase the lifespan of artificial grass by providing a barrier between the grass fibers and concrete. Over time, this can prevent fibers from flattening or becoming damaged.
Can I Lay Artificial Grass on Uneven Concrete?
Yes, you can lay artificial grass on uneven concrete, but it may require some additional preparation work. The concrete surface must be leveled before artificial grass can be installed.
In addition, if the concrete surface has large cracks or holes, these should be repaired before installing artificial grass. Concrete patching compound can be used to fill cracks and holes.
