How Long Does Artificial Grass Take To Settle?

Artificial Grass Care Guide

A new artificial lawn does not always look its best the moment it is laid. The grass usually arrives in a tightly packed roll, so the pile may sit flat in places and faint lines can sometimes be seen across the surface. One section may even look slightly lighter or darker than another, simply because the fibres are leaning in different directions.

Most of this improves naturally once the grass has been unrolled, brushed and given time to recover. You should normally see a difference within the first week, with the lawn looking much fuller after around two to four weeks. Dense, longer-pile grass can take closer to six or eight weeks to reach its finished appearance, especially during colder weather.

That does not mean the garden has to stay out of use for two months. Artificial grass can usually be walked on much sooner, once the fitting is complete and any adhesive has properly cured. Settling refers more to the way the lawn looks and sits over time than the point at which it becomes usable.

First Week The pile starts to lift and the surface begins to look more even.
Two To Four Weeks Most lawns look noticeably fuller and more natural.
Up To Eight Weeks Dense or longer-pile grass may need extra time to fully recover.

The Quick Answer

Artificial grass generally takes between two and four weeks to settle. Some dense or longer-pile lawns may take up to eight weeks before the fibres have fully lifted and any marks from being rolled have faded.

Time After Fitting What You Can Expect
First 24 hours The pile may look flat and lines from the roll can still be visible.
First week The fibres begin to lift and the surface starts to look more even.
Weeks 2 to 4 Most lawns look noticeably fuller and more natural.
Weeks 4 to 8 Dense or longer-pile grass should be close to its final appearance.

These timings are only a guide. The type of grass, the weather and the standard of the installation all make a difference.

What Does Settling Mean For Artificial Grass?

When people talk about artificial grass settling, they are usually describing the pile recovering after it has been stored and transported in a roll.

The fibres are pressed closely together while the grass is rolled up. Once it is laid flat, they begin to loosen and stand back up. Brushing the pile in the opposite direction to the way it naturally leans can speed this up and help the lawn look fuller.

The way light catches flattened grass can also make the surface look patchy. It may seem as though one piece is a different shade, even when it came from the same roll. As the fibres lift, these differences often become much less noticeable.

The base underneath the lawn is a separate matter. It should already be firm, level and properly prepared before the grass goes down. Settling will not remove a deep dip, repair a loose join or flatten an area where the base has not been compacted correctly.

Anyone fitting the lawn at home should follow our guide on how to lay artificial grass, as careful preparation has a much greater effect on the final result than simply waiting for the surface to improve.

How Long Does Artificial Grass Take To Fully Settle?

The lawn will change gradually rather than suddenly looking finished one morning. Most of the improvement happens during the first few weeks.

The First 24 Hours

Freshly laid artificial grass often looks quite flat. The fibres have only just been released from the roll and will usually lean in the same direction.

There may also be light creases or pressure lines across the lawn. These are common at this stage and often begin to relax once the grass has been laid out.

Try to keep use light on the first day, particularly where joining tape or artificial grass adhesive has been used. Curing times vary, so always follow the instructions for the product used during installation.

Heavy planters, garden furniture and play equipment should also be left off the lawn until the fitting is secure.

The First Week

You should start to see the pile lifting during the first week. The grass may still look flatter in some places, but the overall surface should begin to feel less uniform and tightly packed.

A stiff broom can be used to brush against the direction of the pile. You do not need to press hard. A steady brush is enough to separate the fibres and help them stand more upright.

Some sections can take longer than others. Grass taken from the centre of a roll may have been under more pressure, while shaded areas can remain cooler and recover more slowly.

Once the adhesive has cured and the edges are secure, normal light foot traffic is usually fine.

Weeks 2 To 4

By the end of the first month, most artificial grass looks much closer to the lawn you expected when you ordered it.

The pile should feel fuller, roll lines should have softened and any apparent changes in colour should be less obvious. Joins can also become harder to notice as the fibres around them lift.

There is no need to keep brushing the entire lawn. Concentrate on any sections that still look pressed down, then allow the grass to recover naturally.

Garden furniture can usually be added once everything is secure, although wide feet or suitable supports will help spread the weight. Leaving a narrow chair or table leg in the same place can create a deeper impression in the pile.

Weeks 4 To 8

Longer and denser lawns sometimes need more time, especially if they were tightly rolled or installed in cool conditions.

By eight weeks, the grass should no longer show obvious signs of compression from the roll. The pile should be more upright and the lawn should sit neatly across the prepared area.

Marks beneath furniture or along a busy route through the garden can still appear later. These are usually caused by pressure and use rather than the original settling period, and gentle brushing will often lift them again.

A visible dip, raised join or loose section that has not changed after several weeks is less likely to be part of normal settling. In those cases, the installation may need to be checked.

What Affects How Quickly Artificial Grass Settles?

No two installations settle at exactly the same pace. One garden may look almost finished after a week, while another continues to improve over the next month. That does not necessarily mean one has been installed better than the other.

A few different factors influence how quickly artificial grass settles.

Pile Height

Longer fibres naturally take longer to recover after being rolled. If you have chosen a luxury artificial grass with a deep, dense pile, do not be surprised if it needs a little longer to stand upright than a shorter landscaping product.

Shorter pile heights tend to recover more quickly because the fibres have less distance to spring back.

Weather Conditions

Warm weather often helps the fibres relax more quickly. During the summer, you may notice the lawn changing over just a few days.

Cooler temperatures do not stop the settling process, but they can slow it down. If your lawn has been installed during the winter, it may take a little longer before it reaches its finished appearance.

Rain will not damage newly installed artificial grass, although it is unlikely to speed up the settling process on its own.

Brushing & General Use

A newly laid lawn does not need constant maintenance, but a gentle brush every so often can help lift fibres that are still lying flat.

Normal foot traffic also plays a part. Walking across the lawn encourages the pile to move naturally, helping it lose the uniform look that often comes from being tightly rolled.

There is no need to overdo it, though. Brushing aggressively every day will not make the grass settle twice as fast.

Installation Quality

Even the highest-quality artificial grass relies on a good installation.

If the base has been properly prepared, the joins have been fitted neatly and the grass has been stretched correctly during installation, the lawn should settle evenly over the following weeks.

Issues such as raised joins, loose edges or noticeable movement beneath the surface are unlikely to improve simply by waiting. Those are usually installation issues rather than part of the natural settling process.

How To Help Artificial Grass Settle Faster

Time is the biggest factor, but there are a few simple things you can do to help your lawn settle naturally.

The first is brushing.

Using a stiff broom to brush against the direction of the pile helps separate compressed fibres and encourages them to stand more upright. This is especially useful during the first few weeks when the grass is still recovering from being rolled.

If you are brushing a larger area, work in sections rather than trying to cover the whole garden in one go. One or two gentle brushes each week is usually enough.

It is also worth giving the lawn a chance to breathe before filling it with furniture. Once the installation is secure and any adhesive has fully cured, introduce heavier items gradually instead of covering large areas straight away.

Keeping the surface clean helps too. Leaves, packaging from the installation or other garden debris can make it harder to see how the lawn is settling, particularly if some fibres are still lying flat.

Most importantly, be patient.

It is easy to compare your lawn with photographs online, but many of those images were taken weeks after installation rather than on the day the grass was fitted. Giving the fibres time to recover naturally often produces the biggest improvement.

What Should You Avoid During The Settling Period?

While artificial grass is hard-wearing, there are a few things worth avoiding during the first few weeks.

  • Placing heavy planters, storage boxes or garden furniture on the lawn before the installation is fully secure
  • Dragging furniture across the surface instead of lifting it into position
  • Walking on joins before the adhesive has reached its recommended curing time
  • Brushing too aggressively or too frequently
  • Assuming every crease or flat area needs immediate repair
  • Covering large sections before the fibres have had a chance to recover

Concentrated weight can hold fibres down before they have had a chance to recover from being rolled. One of the most common mistakes is trying to fix something that would have improved naturally after another week or two. A quick brush is often all that is needed while the lawn continues to settle.

Signs Your Artificial Grass Has Fully Settled

Most lawns do not suddenly reach a point where they are “finished”. The changes become less noticeable over time until the grass simply looks the way you expected it to.

The Fibres Look More NaturalThere are far fewer flattened patches than when the lawn was first installed.
Roll Lines Have FadedPressure marks from storage and transport are no longer obvious.
The Surface Looks More EvenApparent shade differences caused by flattened fibres have reduced.
Joins Are Less NoticeableThe lifted pile helps the sections blend together more naturally.

From this point, looking after the lawn becomes routine maintenance rather than helping it settle. An occasional brush, removing leaves and keeping the surface clean will help it continue looking its best throughout the year.

When Settling Is Not The Problem

It is easy to assume that any issue with a new lawn just needs more time, but that is not always the case.

If you still have raised joins, ripples, loose edges or obvious dips after several weeks, the installation may need to be checked. Those issues are usually linked to the fitting or the base underneath rather than the grass settling naturally.

The same applies if part of the lawn feels uneven underfoot or moves when you walk across it. Artificial grass should feel secure once it has been installed correctly.

If you are unsure whether what you are seeing is normal, compare how the lawn changes over a couple of weeks rather than from one day to the next. Most settling happens gradually. If nothing has improved at all, it is worth speaking to your installer or reviewing the installation if you fitted the lawn yourself.

Does Artificial Grass Settle Differently On Different Surfaces?

The fibres recover in much the same way regardless of what is underneath them, but the installation beneath the grass can influence the finished result.

Prepared Soil

Artificial grass laid on a well-prepared soil base may take a little longer before everything feels completely established, simply because there are more stages involved in preparing the ground before the grass is fitted.

Concrete

Concrete provides a solid, stable base from the start, so the overall appearance is often more consistent straight after installation. The pile will still need time to recover from being stored in a roll.

Decking

Decking also creates a firm surface when it is stable and correctly prepared. As with every installation, the fibres still need time to lift and lose any visible compression marks.

Whichever surface you have chosen, careful preparation will always have more impact on the finished result than waiting for the lawn to settle.

Artificial Grass Settling Times FAQs

Can You Walk On Artificial Grass Straight Away?

It depends on how the lawn has been installed. If adhesive has been used around the edges or joins, it is important to wait until it has fully cured. Once the installation is secure, light foot traffic is usually fine.

Can I Put Furniture On Artificial Grass Immediately?

It is best to wait until the installation is complete and any adhesive has cured. Leaving heavy furniture off the lawn for the first few days also gives the fibres more chance to recover naturally.

Why Does My Artificial Grass Look Flat?

This is one of the most common things people notice after installation. The fibres have been compressed while the grass was rolled for transport and usually begin to lift over the following weeks. Brushing the pile can help speed up the process.

Will Artificial Grass Look More Natural Over Time?

Yes. As the fibres recover and stand more upright, the lawn often looks fuller and more even than it did on the day it was fitted.

Does Brushing Help Artificial Grass Settle?

It can. Brushing against the direction of the pile helps separate flattened fibres and encourages them to stand upright, particularly during the first few weeks.

How Long Before Pets Can Use Artificial Grass?

Once the installation is secure and any adhesive has fully cured, pets can usually use the lawn as normal. If you are choosing a lawn specifically for dogs or other pets, take a look at our range of Pet Artificial Grass.

Why Can I Still See The Joins?

Joins are often more noticeable immediately after installation because the surrounding fibres are still lying flat. As the pile lifts, they usually become much less obvious. If a join remains raised or clearly visible after several weeks, it is worth having it checked.

Does Rain Help Artificial Grass Settle?

Rain will not normally make the grass settle faster, although it will not harm the lawn either. Time and the natural recovery of the fibres are much more important.

How Do I Know If My Artificial Grass Has Been Installed Incorrectly?

Persistent ripples, loose edges, movement beneath the surface or raised joins are all signs that the installation may need attention. These problems are different from the temporary flattening that most new lawns experience.

Can Artificial Grass Settle Unevenly?

Some areas may recover slightly faster than others, particularly if the fibres were compressed differently inside the roll or one part of the garden receives more sunlight. Small differences usually become less noticeable over time.

Give Your New Lawn Time

If your new artificial grass does not look perfect on day one, there is usually no cause for concern. Most lawns continue to improve over the first few weeks as the fibres recover and the surface takes on a more natural appearance.

A little patience, the occasional brush and allowing the installation to cure properly are often all that is needed. Before long, those early signs of being rolled for transport will be forgotten, leaving you with a lawn that is ready to enjoy for years to come.
