Application Basics: Use a drop spreader, apply in layers, and brush thoroughly.
Maintenance: Regular brushing and occasional top-ups keep turf looking and performing its best.

For best results, prepare the turf, calculate infill needs, and apply it evenly. Professional installation ensures precision and long-term quality, especially for high-use areas like sports fields or playgrounds.

How to Install Sand Infill for Artificial Grass

Types of Turf Infill Materials

Choosing the right infill can make a big difference in how your synthetic turf performs. Here’s a closer look at some of the most common options and their key benefits.

Popular Infill Material Options

Silica Sand
Silica sand is a go-to choice for residential turf installations. It provides stability and weight to keep turf fibers upright, while also allowing for proper drainage. A 50-pound bag typically covers 25–35 square feet. On the downside, it offers limited odor control and can retain heat during the summer months.
Rubber Crumb
Rubber crumb is often used in athletic fields and playgrounds because it absorbs shock effectively. Made from recycled tires, it cushions impacts and provides consistent performance. However, it tends to retain odors and doesn’t drain as efficiently as sand-based options.
Zeolite
Zeolite is a standout choice for areas with pets. This volcanic mineral naturally absorbs odors, making it ideal for dog runs and pet-friendly lawns. While it’s more expensive than silica sand, its odor-controlling properties are a major advantage.
Acrylic-Coated Sand
Acrylic-coated sand, like Envirofill, is a premium option. It resists compaction, has excellent durability, and often includes antimicrobial properties. Available in various grades (12–20, 16–30, and 30–50), it works well in high-traffic areas and specialized applications.
Specialized Blends
Specialized blends are tailored to specific needs, such as reducing heat or enhancing pet safety. For example, TºCool infill helps lower surface temperatures in hot climates, while pet-specific blends combine odor control with antimicrobial features.

Understanding these materials helps you choose the best infill based on your climate, intended use, and budget.

How to Choose the Right Infill

If you live in a hot area, cooling infills like TºCool can help keep turf temperatures down. For regions with heavy rain, materials like silica sand or zeolite, which offer excellent drainage, are better suited. Areas with freeze-thaw cycles require infills that resist compaction and maintain consistent performance year-round.

Your turf’s purpose also matters. Pet areas benefit from infills with strong odor control, such as zeolite or pet-specific blends. Athletic fields and playgrounds need materials like rubber crumb or acrylic-coated sand for their shock absorption and durability. For general landscaping, silica sand is a cost-effective and reliable choice.

Budget is another factor. Silica sand is one of the most affordable options, typically applied at a rate of 1.5 to 2 pounds per square foot. Although premium options like Envirofill cost more upfront, they often pay off in the long run with lower maintenance needs and better durability.

Infill Material Comparison

Here’s a quick comparison of how each infill type performs across key factors:

Infill Type	Durability	Drainage	Odor Control	Recommended Applications
Silica Sand	Moderate	Good	Low	Landscaping, putting greens
Rubber Crumb	High	Moderate	Low	Sports fields, playgrounds
Zeolite	Moderate	Good	High	Pet turf, residential lawns
Acrylic-Coated Sand	High	Good	Moderate	High-traffic areas, sports fields
Pet/High-Traffic Blends	High	Good	High	Pet areas, commercial installations

For sports fields, infill amounts range from 2 to 2.5 pounds per square foot, depending on pile height and usage. As mentioned earlier, a 50-pound bag typically covers 25 to 35 square feet.

Different grades of infill serve specific purposes. For general applications, 16–30 grade works well, while 30–50 grade is better for short-pile systems. On putting greens, contractors often use a combination approach: 5–6 pounds per square foot of base sand, plus an extra pound of specialized top-dress infill to enhance ball roll and surface performance.

Rubber crumb handles temperature fluctuations well, acrylic-coated sand maintains its properties longer, and zeolite effectively manages freeze-thaw cycles while controlling odors.

Preparing for Infill Application

Getting your site ready is key to achieving a polished look and ensuring the turf performs as it should.

Site Preparation Steps

Before you start applying infill, make sure your artificial turf is properly prepped:

Brush the grass fibers upright using a power broom or a stiff-bristled broom. This helps the infill granules settle evenly between the fibers.
Address any flat or matted areas by thoroughly brushing them, as uneven fibers can disrupt the infill distribution.
Clear away all debris to create a clean surface.
Inspect the area for low spots or uneven patches and fix them. Also, ensure the weed barrier and edging are secure to prevent movement during the infill process.

Once the site is ready, gather the tools you’ll need for the application.

Required Tools and Supplies

Using the right tools makes the infill process smoother and more efficient. Here’s what you’ll need:

A drop spreader for evenly distributing infill across the turf.
A power broom or stiff-bristled broom to work the infill into the grass base.
A utility knife for cleanly opening infill bags.
Safety gear like gloves and goggles to protect your hands and eyes.
A rake for leveling and clearing the area before and after application.
For dense turf, such as putting greens, a plate compactor can help settle the infill more effectively.

Calculating Infill Quantities

Accurate calculations are essential to avoid running out of infill or having too much leftover. Here’s how to estimate your needs:

For instance, if your turf area is 500 square feet and requires 2 pounds of infill per square foot, you’ll need around 1,000 pounds of infill. That’s about 20 bags of 50 pounds each.
Adjust quantities based on specific applications, as some installations may have different requirements.
Check your spreader’s weight capacity to ensure it’s manageable during application.
Follow the manufacturer’s recommendations and consider external factors like weather. Avoid applying infill on rainy or wet days, as moisture can cause clumping and make distribution uneven.

Proper preparation and planning set the stage for a successful infill application.

How to Apply Turf Infill

Once you’ve prepared the groundwork, it’s time to apply the turf infill. Achieving a professional finish depends on a systematic process that ensures the infill is evenly distributed and properly settled.

Preparing Turf Fibers

Start by getting the turf fibers ready for infill. Use a power broom or a stiff rake to brush the synthetic fibers into an upright position. This step is crucial because it allows the infill to penetrate more easily, rather than just sitting on top of the blades.

When the fibers are standing upright, the infill can settle correctly into the turf’s backing, ensuring an even spread. This process also helps break in the texture of new turf.

Work methodically across the entire area, giving extra attention to any flattened or matted sections. A power broom works particularly well here, as it not only lifts the fibers but also gives the turf a more polished look. Once this step is complete, you’re ready to start spreading the infill.

Spreading Infill Evenly

For the best results, use a drop spreader to apply the infill in parallel rows, moving side-to-side across the turf. This technique ensures consistent coverage and avoids the unevenness that can happen with manual spreading.

Apply the infill in 1/4-inch layers to keep the distribution even. Adding all the infill at once can lead to poor settling and uneven coverage, so layering is key. This approach also gives you better control over the final depth and ensures the infill is spread evenly throughout the turf system.

The amount of infill needed depends on the type of turf. For shorter, textured systems, aim for 2 to 2.5 pounds per square foot, depending on the pile height. For putting greens, you’ll need roughly 5 to 6 pounds per square foot of base sand.

A helpful rule of thumb is to use 3/8 inch to 1/2 inch of infill for every 1 inch of pile height. For example, if your turf has a pile height of 1.5 inches, you’ll need around 3 to 5.25 pounds of infill per square foot. Once you’ve applied the first layer, it’s time to secure and settle the infill.

Finishing the Application

After each layer of infill is spread, use a broom to work the material into the turf until no granules are left sitting on top. This step is essential for supporting the fibers properly.

Repeat the process of applying and brooming until you’ve reached the desired depth. The infill should be fully worked into the backing, leaving no granules visible on the surface. For putting greens, a walk-behind plate compactor is recommended to compact the sand into the base, as brooming alone may not be sufficient for dense pile turf.

Once all layers are applied, use a depth gauge to confirm that the infill has reached the proper depth. This final check ensures the infill is evenly distributed throughout the turf.

To finish, trim any excess turf for a clean edge. Avoid using metal tools to work the infill, as these can damage the synthetic fibers. Stick to tools like a power broom, stiff brush, or turf rake for all final touches.

When you’re done, the turf should have no visible infill granules on the surface. The fibers should stand upright, fully supported by the infill beneath, giving the installation a polished and professional appearance.

Maintaining and Fixing Turf Infill

Once your turf is installed, regular upkeep is the key to keeping it looking great and functioning well. Routine care helps extend its lifespan and maintain its appearance.

Regular Maintenance Tasks

One of the most important things you can do is brush your turf at least once a month. Using a power broom or a stiff-bristled push broom, you can lift the turf fibers and evenly spread the infill. This prevents matting and compaction, keeping the surface looking and feeling its best.

Every three to six months – or more often if the turf sees heavy use or extreme weather – check the infill levels. Signs that you might need to add more infill include flattened or matted fibers, an uneven surface, or visible turf backing. If the turf feels hard underfoot or the fibers don’t bounce back after brushing, it’s time to top up the infill.

To make these tasks easier, tools like a power broom, drop spreader, turf rake, and measuring tool can come in handy.

High-traffic areas and pet zones require extra attention. In these spots, brushing every two weeks and checking infill levels more frequently can help keep the turf in good shape. For pet areas, consider using infill with antimicrobial or odor-controlling properties, and clean up waste promptly to maintain a clean and fresh surface.

Staying consistent with these maintenance tasks can prevent bigger issues that might require more extensive fixes.

Fixing Common Problems

If the turf starts showing problems like uneven or compacted infill, here’s how to address them:

Uneven Infill: Heavy foot traffic, weather, or an improper initial application can cause uneven infill distribution. Start by brushing the infill with a power broom or turf rake in multiple directions. If that doesn’t solve the issue, add infill in thin layers and brush thoroughly between applications.
Clumping: Moisture, pet waste, or debris can cause infill particles to clump together. Remove visible debris first, then use firm brushing to break up the clumps. For persistent clumping, you might need to remove the affected infill entirely and replace it with fresh, dry material.
Compacted Infill: Infill that becomes compacted can make the turf feel hard and less cushioned. To fix this, loosen the infill by brushing against the grain with a rake or power broom. Then, add fresh infill in thin layers to restore the proper depth and resilience.

Different infill types require slightly different care. Organic options like cork or coconut may need more frequent replacement due to decomposition, while rubber infill can shift more easily in hot conditions. Even coated or antimicrobial infills benefit from regular checks to ensure they remain evenly distributed.

Weather and Climate Effects

The warm, dry climate of Orange County presents unique challenges for turf infill maintenance. High temperatures can cause the infill to expand, raising the surface temperature and potentially making the turf uncomfortable during summer. Dry conditions can also make the infill shift around, leading to uneven distribution.

Winter rains bring their own challenges. Heavy rainfall can wash infill away from sloped areas or cause it to pool in low spots. After a storm, inspect the turf carefully, redistribute the infill with a power broom, and add fresh material as needed.

Regular inspections, especially after heatwaves or heavy rains, are essential to keeping your turf in top shape.
