When you are laying flagstones for a walkway, you may want to use a product called “mulch” as a filler. Mulch is lightweight and can be used to cover the spaces between flagstones. Wood bark is another option, but it can shift during high winds.
Cocoa shell mulch can be used as well, but you should know that the hulls of cocoa are toxic to dogs.
Sand is a popular product for putting between flagstone. It will fill in the gaps between the stones and can be brushed in using a push broom. Smaller granules of sand will work better for gaps between stones close together.
If you have a large gap, you may want to use 1/4-inch gravel.
Flagstone is available in a variety of colors, shapes, and textures. This diversity allows you to create a hardscape that is uniquely yours. There are also different textures, thicknesses, and levels of permeability, so it’s important to choose the right material for your project.
Depending on your budget, the type of flagstone you choose will determine the cost of the project. Some stones are rarer and more expensive than others, and they may require a larger budget than more common types.

What do you fill flagstone joints with?
Flagstone joints can be filled with a variety of materials such as sand, gravel, crushed stone, mortar mix and caulk. The material choice you make should match the style of the flagstone and should be something that allows for adequate drainage, as any water that is not able to properly drain can adversely affect the stability of the flagstone.
Sand or gravel are the most common materials used to fill flagstone joints, as they are easy to work with and can be filled in quickly. As opposed to mortar mix, sand or gravel can be made level and compacted in order to keep the flagstone stable and looking its best.
Caulk can also be used, although it is not as professional looking and usually is not recommended since it can crack due to drainage or temperature changes.
For a more professional, long-lasting look, mortar mix should be used. While it may take more time and effort to prepare, it is an ideal choice for spaces with heavy foot traffic, as it will not be affected by the elements or foot traffic like caulk and sand or gravel.
In addition, if the flagstone is for an outdoor space, the mortar mix can come with waterproofing ingredients that are beneficial for protecting from freezing and thawing that can occur due to extreme temperatures.
No matter the joint material you choose, be sure to prepare the area correctly before laying the flagstone and filling in the joints. Make certain the flagstone base is level, clean, and dry. This will ensure that the flagstone will stay looking its best for years to come.
Can I use paver sand with flagstone?
Yes, you can use paver sand with flagstone. Paver sand is made up of a combination of finely crushed stone, sand, and dust particles, making it an ideal material for filling joints between pavers and other hardscapes.
When used with flagstone, the paver sand will act similarly to mortar, filling the joints between stones and helping to prevent weeds, insects, and water from penetrating beneath the flagstone and damaging it.
To ensure the best results, use a stiff broom to sweep the sand into the joints and wet the area or mist the sand lightly after application to help the sand settle into place. Once the paver sand is completely dry, the joints should be completely filled and solid.
When should you not use polymeric sand?
Polymeric sand should not be used in any ground area that is subject to standing water, such as areas that are prone to flooding. Additionally, it should not be used in areas with large amounts of tree roots or organic matter that could destabilize the sand.
It is not recommended for chill-set flagstone or for patios where furniture is moved regularly as the movement can scrape and disturb the sand. Furthermore, Polymeric sand should not be used with cobblestones or other stones that feature irregular, pitted or chiseled edges as the sand will not effectively fill in the joints.
Lastly, never use it in cold weather, as the sand will not harden as it would in optimal temperatures.
What are the problems with polymeric sand?
The main problem with polymeric sand is that it can harden up and become difficult to work with. This can cause problems when setting pavers, walkways, and patios as the installation process can become difficult and time consuming.
Additionally, polymeric sand can shrink and become loose which can lead to weeds and grass growing between the paver joints. This can be unsightly and also weaken the stability of the structure as the weeds will push against the pavers and can eventually cause damage.
Its also important to note that polymeric sand can be significantly more expensive than traditional sand, so it may not be the best financial decision for every project. Lastly, some brands of polymeric sand can be susceptible to water damage and can not be used in certain climates or locations.
Therefore, it’s important to do your research and make sure the polymeric sand is a suitable option for your area.
Is there a difference between paver sand and polymeric sand?
Yes, there is a difference between paver sand and polymeric sand. Paver sand, also known as joint sand, is a coarse form of natural sand or crushed stones. It is used to fill in the joints or seams between pavers and provide structural support to the pavers.
It is easier to install than polymeric sand and is great for stabilizing pavers.
Polymeric sand is a specially formulated mixture of sand and binder that is designed to lock pavers into place. It is an advanced form of sand that sets and hardens when water is added. It also provides greater flexibility between the pavers, resisting contamination from weeds and insects, and filling in gaps between the pavers.
Polymeric sand is more expensive than traditional paver sand, but it is more durable and provides a longer-lasting finish to your patio or walkway.
Is polymeric sand necessary?
The short answer is “no,” polymeric sand is not necessarily necessary for all residential landscaping and hardscaping projects. However, there are some tangible benefits to using it in certain situations.
Polymeric sand is a binding agent that is specially designed to fill the joints between pavers. When used correctly, it helps to prevent the growth of weeds, ants, and other unwanted pests while helping to lock pavers into place and reduce the likelihood of shifting and settling.
It can also help to improve the overall look of the project by creating a neat, uniformed surface. For these reasons, many homeowners and landscapers choose to use polymeric sand when installing pavers in areas around the home, such as driveways, patios, and walkways.
How long does polymeric sand last?
Polymeric sand has an incredibly long lifespan when applied and maintained properly. Most manufacturers claim that it can last as long as 10-20 years, although in certain climates it may have to be replaced or reset more often.
The sand is made up of a combination of fine aggregates and sand, along with a binder that creates a durable and flexible material that can withstand changes in temperature and humidity. When applied correctly, the sand is designed to bind together the paver joints and form a stronger, more durable joint than regular sand.
The sand also helps to inhibit weed growth and keep out unwanted insects. Regular maintenance, including edging and re-sanding, will help make sure the sand stays intact and the paver joints are secure.
Will water drain through polymeric sand?
Yes, polymeric sand is designed so that water can pass through it, while still providing strong a strong and stable bed for pavers. The polymers used prevent the sand from washing away or becoming muddy.
As opposed to regular sand, polymeric sand hardens when water is added, filling in gaps and locking the pavers in place. Additionally, polymeric sand contains polymers that swell when they come into contact with moisture, providing a firm and secure bond.
The sand also trap soil particles, preventing them from washing away with water. As a result, the sand will allow water to pass through, while still retaining its structural integrity.
Does polymeric sand harden like concrete?
No, polymeric sand does not harden like concrete. Polymeric sand is a mixture of sand and polymer binders which harden after being activated with water. The binders allow the sand to harden like a rigid, solid mass.
It does not, however, harden to a level like concrete, which is a combination of cement, an aggregate such as sand or gravel, and water that hardens as it cures. As a result, polymeric sand is not a substitute for concrete.
It is typically used to fill the gaps and spaces between stone pavers and hardscapes such as concrete and asphalt to add stability, minimize shifting, control weeds, and prevent the growth of moss and other plants.
How do you fill space between patio stones?
When filling in the space between patio stones, the most important thing is to use a material that will not settle or erode over time. One good option is to use potting soil or sand, as they are relatively inexpensive and will stay in place.
Before filling, you should lay a layer of landscape fabric or plastic sheeting over the area to help keep the soil or sand from shifting during heavy rain. After that, simply fill in the space with the chosen material.
If you are using sand, it should be dampened with a bit of water to keep it from shifting as well. Once the material is in place, you can use a broom to level it out and make sure all the gaps are filled.
Be sure to attach any stones that may have shifted during the process. Finally, for a more finished look, you can add a layer of attractive gravel on the surface to complete the patio stone installation.
What to use to fill in gaps between paving slabs?
One of the best materials to use to fill in gaps between paving slabs is polymeric sand. Polymeric sand is sand that has an added polymer (a type of plastic) which helps to bind together the sand granules and fill in the cracks between paving stones.
It helps to prevent weeds, insects, and other animals from getting between the slabs while also reducing the amount of dust and dirt that might otherwise build up in the gaps. It is also easy to apply and sets quickly.
Moreover, polymeric sand won’t wash away with rain or water runoff, and it can withstand harsh weather conditions. It is usually available in a variety of colors, allowing you to match the existing bricks or paving stones.
Other materials used to fill in paving gaps include epoxy and acrylic sealers, gravel, and coarse sand. However, polymeric sand typically provides the most durable and low-maintenance solution.
What is the mortar for flagstone?
The mortar for flagstone typically consists of Portland cement, hydrated lime, and masonry sand. It creates a strong bond with the stones and helps moisturize the joint. The mortar should be a dry mix of three parts masonry sand and one part Portland cement, plus enough hydrated lime to make a creamy, variety, and easy to spread mortar.
The lime helps with adhesion and flexibility as well as acting as a waterproofing agent. It also helps prevent cracking in the mortar with frost heave and thermal cycling. The final mixture should have a consistency similar to peanut butter and have a fine texture, which allows it to be troweled into a tight joint.
When applying the mortar, it is important that the flagstone sits level, is firmly tapped into the mortar, and that all gaps between the flagstone pieces and the wall are filled. When the mortar is dry and hardened, it should create a strong, durable bond that lasts for many years.
What kind of sand do you put under flagstone?
The type of sand you use beneath flagstone will depend on the application. If you are laying flagstone in a walkway, then you can use coarse sand, such as builder’s sand or patio paving sand. This type of sand has larger grains than most other sands, which will help provide enough stability for the flagstone and help prevent the flagstone from sinking into the ground.
If you are laying flagstone in an area with better drainage, such as for a patio or pathways, then you can use fine sand, such as masonry sand or quartz sand. This type of sand has smaller, finer grains that help to promote water movement and better drainage, allowing excess water to enter the surrounding soil around the flagstone.
No matter what type of sand you decide to use beneath your flagstone, be sure to compact it in place with a compactor or tamper before laying the flagstone. This will help ensure that your flagstone is installed correctly and will provide a stable, level base.
How can I use polymeric sand without a compactor?
Polymeric sand is a type of sand that is often used in construction and landscaping projects. It is made of a type of plastic that is combined with sand particles. This type of sand is used to fill joints between pavers, bricks, and stones.
It is also used to create a level surface for pavers, bricks, and stones. Polymeric sand is a type of sand that is often used in construction and landscaping projects. It is made of a type of plastic that is combined with sand particles.

One way is to simply spread the sand over the area where you will be placing the pavers, bricks, or stones. Another way is to pour the sand into the joints between the pavers, bricks, or stones. You can also use a tool to help spread the sand into the joints.
Can you hand tamp polymeric sand?
Yes, you can hand tamp polymeric sand. This type of sand is used in various applications, including paving stone and flagstone patios, as well as between brick and block retaining walls. Hand tamping is the process of pressing the sand down into the joints of pavers and walls to create a stable and solid base.
When tamping polymeric sand, you will need to use a specially designed rubber mallet. This type of mallet is designed to prevent the sand particles from compressing too tightly, which can result in a weaker bond.
Additionally, it’s important to ensure that the sand is evenly spread before you begin tamping. Once the sand has been tamped in place, you will also want to make sure to activate it with water according to the manufacturer’s instructions.
This will ensure that the sand sets properly and creates a solid foundation.
