How Do You Know When to Add Additional Infill to Artificial Grass?
Artificial grass is designed to be durable, attractive, and low-maintenance, but the turf system still needs occasional maintenance to perform its best. One of the most important—and often overlooked—parts of artificial turf maintenance is infill.
Infill helps support the turf blades, improve stability, provide cushioning, and keep synthetic grass looking full and natural. Over time, however, infill can become compacted, displaced, or washed away. High-use areas and homes with pets may require additional infill more frequently than lightly used lawns.
So, how do you know when your artificial grass needs more infill?
At Synthetic Turf Refresh, we help homeowners maintain their synthetic grass through professional cleaning, deodorizing, grooming, and turf maintenance. Here are some of the most common signs that your artificial grass may benefit from additional infill.
What Is Artificial Turf Infill?
Infill is the material placed between the synthetic turf blades. It sits on top of the turf backing and helps support the blades so they remain upright.
Depending on the turf system and the homeowner’s needs, different types of infill can provide different benefits.
Infill can help:
Support and lift turf blades
Improve the appearance of synthetic grass
Add weight and stability to the turf
Provide cushioning underfoot
Protect the turf backing
Improve drainage characteristics
Help control pet odors
Reduce surface temperatures with certain specialized products
Not every artificial grass installation uses the same type of infill, so it’s important to know what is already installed before adding more.
Signs You May Need Additional Infill in Your Artificial Grass
You don’t necessarily need to add infill simply because your turf has been installed for several years. Instead, look for signs that the existing infill has become depleted or uneven.
1. Turf Blades Are Laying Flat
One of the most noticeable signs is turf that doesn’t stand upright like it used to.
Flattened grass can be caused by foot traffic, pets, furniture, weather, and compacted or insufficient infill.
Before automatically adding more infill, the turf should generally be groomed to determine whether the blades can be restored to an upright position.
If grooming doesn’t restore the appearance, the turf may need additional infill or other maintenance.
2. You Can See the Turf Backing
If you can easily see the backing material between the turf blades in areas where you shouldn’t, it could indicate that the turf doesn’t have enough infill.
This can be particularly noticeable in high-use areas.
3. High-Traffic Areas Look Different
Walkways, entrances, play areas, patios, and areas where people frequently gather tend to experience more wear than the rest of the lawn.
Over time, infill can shift or become compacted in these areas.
If one section of your artificial grass looks significantly flatter or thinner than the surrounding turf, it may need to be groomed and evaluated for additional infill.
4. Infill Has Become Uneven
Heavy rain, cleaning, foot traffic, pets, and normal use can cause infill to migrate.
You may notice areas with too much infill and other areas where the turf appears under-filled.
Redistributing the existing infill may solve the problem in some situations. In other cases, additional material may be necessary.
How Does Infill Help With Pet Odor?
For homeowners with dogs, infill can play an important role in artificial turf odor control.
Pet urine passes through the turf and into the drainage system. However, urine and organic contaminants can remain within the turf system if the area isn’t properly maintained.
Certain infill products are specifically designed to help manage pet odors.
Zeolite Infill
Zeolite is a naturally occurring mineral commonly used in pet turf systems because of its ability to help absorb and manage ammonia-related odors.
This makes zeolite-based infill a popular option for homeowners with dogs.
However, infill alone isn’t a substitute for cleaning. If urine, pet hair, dirt, and organic debris have accumulated in the turf, simply adding more infill won’t solve the underlying odor problem.
Cleaning, rinsing, deodorizing, and proper drainage should all be part of a pet turf maintenance program.
Antimicrobial or Odor-Control Infill
Some manufacturers offer specially treated infill designed to provide additional odor-control or antimicrobial properties.
These products can be useful in heavily used pet areas, but homeowners should always verify compatibility with their specific turf system.
Can Infill Help Control Artificial Turf Heat?
Yes—but not all infill provides the same heat-control benefits.
Artificial grass can become hot in direct sunlight, particularly during the summer. Standard silica sand infill doesn’t eliminate this issue, but some specialized infill products are designed to help reduce surface temperatures.
Cooling infills may use specialized materials or technology designed to retain moisture and provide evaporative cooling when wet.
Some products are also designed to reflect more solar energy or reduce the amount of heat absorbed by the turf system.
For homeowners concerned about hot artificial grass, it’s important to choose a product specifically designed for cooling rather than assuming that adding more standard infill will make the turf cooler.
Proper watering, shade, turf selection, and specialized cooling products can all play a role in managing artificial turf temperatures.
Different Types of Infill for Residential Artificial Grass
There are several types of infill available for residential applications. The best choice depends on how the turf is being used, whether pets are present, the climate, and the existing turf manufacturer’s recommendations.
1. Silica Sand
Silica sand is one of the most common types of artificial turf infill.
It is generally affordable and helps support turf blades while adding weight and stability.
Best for:
General residential lawns
Low to moderate traffic
Homeowners looking for an economical infill option
Silica sand is not specifically an odor-control product, so pet owners may want to consider additional odor-management solutions.
2. Coated Sand
Coated sand infill is typically sand that has been treated with a coating designed to provide additional performance characteristics.
Depending on the product, coatings may help with antimicrobial performance, odor management, or other turf-system benefits.
Best for:
Residential lawns
Pet areas
Homeowners looking for enhanced performance compared with standard sand
Product specifications vary, so always check the manufacturer’s claims and compatibility.
3. Zeolite
Zeolite is particularly popular for pet-friendly artificial turf.
Its ability to help manage ammonia-related odors makes it a common choice for homes where dogs frequently use the synthetic grass.
Best for:
Dog owners
Pet potty areas
Odor-control applications
Zeolite can be especially useful when incorporated into a larger pet-turf cleaning and maintenance program.
4. Cooling Infill
Cooling infills are designed specifically to help address the heat associated with artificial grass.
Different products use different technologies, so performance varies.
Best for:
Sunny backyards
Play areas
Pool decks
Hot climates
Homeowners concerned about turf surface temperatures
Cooling infill is generally a specialty product rather than a universal replacement for standard infill.
5. Crumb Rubber and Specialty Performance Infills
Rubber-based and other specialty infills are used in certain turf applications because of their shock absorption and performance characteristics.
However, they aren’t necessarily the first choice for every residential lawn, particularly when homeowners prioritize a natural feel, odor control, or specific environmental considerations.
The right infill should always be selected based on the turf manufacturer’s recommendations and the intended use of the area.
What About High-Use Areas?
High-use areas deserve special attention when it comes to infill maintenance.
If your artificial grass is frequently used for:
Dogs running and playing
Children’s play areas
Outdoor entertaining
Sports and recreation
Poolside activity
Walkways
Commercial or community spaces
the infill may become compacted or displaced faster than it would in an area that receives little traffic.
Rather than automatically adding infill across the entire lawn, a professional can evaluate the high-use areas and determine whether the existing infill simply needs to be redistributed or whether additional material is necessary.
Should You Add Infill Before or After Cleaning?
In many cases, cleaning and grooming should happen before adding additional infill.
Why?
Because dirt, organic debris, pet hair, and contaminants can become trapped between turf blades. Adding fresh infill on top of a dirty turf system can make the maintenance problem more difficult to address.
A professional maintenance process may include:
Removing surface debris
Deep cleaning the turf
Rinsing the turf
Deodorizing when necessary
Grooming or power brushing
Evaluating the existing infill
Redistributing or adding infill as needed
This approach allows the turf to be evaluated before new material is installed.
How Often Should Artificial Turf Get Additional Infill?
There isn’t a universal schedule.
Some artificial turf installations may go years without needing additional infill, while high-use pet areas may require more frequent evaluation.
Instead of relying solely on a calendar, look for the warning signs:
Is the turf flattening? Is the infill level noticeably low? Are high-use areas looking different? Are the turf blades difficult to stand back up? Is odor becoming an issue?
These are better indicators that your turf may need maintenance.
Don’t Just Add More Infill—Maintain the Entire Turf System
Additional infill can be an important part of artificial turf maintenance, but it isn’t a cure-all.
If your artificial grass has a persistent urine odor, adding infill without cleaning the turf first may not solve the problem.
Likewise, if turf blades are laying flat, adding more infill without properly grooming the turf may not produce the results you’re looking for.
A professional evaluation can determine whether your turf needs cleaning, deodorizing, grooming, infill redistribution, additional infill, or a combination of these services.
