How long does polymeric sand need to dry before sealing?
If us- ing polymeric sand, you caninstall it after the sealerapplication has properly cured for 24 - 48 hours. If polymeric sandis installed prior to sealing, be sure surface is dry for 24 hours before applying sealer. Does polymeric sand soften wet?
Is polymeric sand easy to install?
The installation of polymeric sand may not get the attention it deserves because it is thought of as being a simple process that can be handed off to anyone. Unfortunately, that is not the case.
Can I use polymeric sand instead of paver sealer?
In some applications where the joints between the pavers are rather large (1/4″ or larger) we suggest using the polymeric sand over the joint stabilizing paver sealer because the polymeric sand tends to hold up better in larger joints. Here is a picture of pavers that have been sealed vs pavers that have not.
What happens if polymeric sand is under water?
UNDER-WATERING causes the polymeric sand to simply form a "crust" on the top. If you only have a crust, you don't have a proper bond in the joints. Eventually, the crust will break away, eroding the joint. It also causes cracks and gaps, because the sand hasn't fully bonded the entire depth of the joint.
Do you need to seal polymeric sand?
Without any kind of sealer, the sand in your joints will blow and wash away. Fortunately, if you use one of Seal \'n Lock's paver sealers, you won't have to worry one bit about purchasing or installing polymer sand.
How do you keep polymeric sand from washing out?
You can protect the joint sand from washing out by sealing the paver surface. Sealing restores the beauty of your pavers. The paver sealer also serves as glue between the joint sand particles hence holding them together, and preventing the sand from being washed away when it rains or during pressure washing.
How soon can you seal polymeric sand?
Traditionally, concrete paver manufacturers have recommended waiting at least 90 days after polymeric sand installation to apply a protective sealant to a paver surface. Nowadays, a 30 day delay is sufficient to allow the evaporation of any remaining natural efflorescence contained in the pavers.
Can polymeric sand be reapplied?
Secondly, you will have to wait a day while the surface dries before you can reapply your new sand. Remember polymeric sand and moisture don't mix until after it's in the joints!

Here is a picture of pavers that have been sealed vs pavers that have not.
What does it mean when sand is polymeric?
If there is a crust forming on the surface of the sand, typically this means that the sand was filled too high or the sand was not watered enough. If the sand was filled too high in the initial installation, the sand will continuously be worn and eroded away.
What is polymeric sand?
Polymeric sand is a sand formula that is swept into the joints of pavers and natural stone to lock in the product, prevent weed growth and insects, and to provide the final touches of any hardscaping job.
Why is it important to familiarize yourself with polymeric sand?
There are universal steps to the process of installing polymeric sand, failure signs, and ways in which you can ensure that your polymeric sand installation will run smoothly.
Why is my sand not setting?
Typically this occurs because there was a rainfall shortly after the installation which caused the sand not to set, the sand was watered for too long, or there is not proper drainage in the base. If the problem is caused by the base, then there is a bigger problem at hand.
How far should you sweep polymeric sand?
Most manufacturers recommend not to sweep the sand more than 10 feet in any direction to avoid separating the delicate formula.
What should not be installed on pavers?
What should not be installed is stone dust or chip dust. That is because this will harden and not allow water to drain through, keeping the water below the pavers and saturating the joints, not allowing the polymeric sand to properly dry and never set.
Why do we put sand in joints?
The reason why we do this step is to ensure that the sand has made its way to the bottom of the joint. The large grains of the sand will lodge themselves part of the way down the joint and will trap the smaller particles near the top making it look like the joint is filled .
How far should I leave sand on pavers?
In fact, it is important to make sure you leave about 1/8" from the top of your pavers. This is critical to help you avoid spill-over once you start watering your joints to activate the sand. Further, overfilled joints will break down over time with traffic on the surface. This will not look good on your project.
Why does sand crack when under-wating?
Eventually, the crust will break away, eroding the joint. It also causes cracks and gaps, because the sand hasn't fully bonded the entire depth of the joint.
What is dominator sand?

How to get the best bonding performance from the top of the joint to the very bottom?
In order to get the best bonding performance from the top of the joint to the very bottom, it is important to make sure you water your joints the correct amount of time using the "shower" setting on your hose attachment.
Can you use polymeric sand on pavers?
Polymeric Sand is great for stabilizing your pavers because it bonds so well. This becomes a problem though, if it is activated and then allowed to dry ON TOP OF instead of between pavers. This problem can be made even worse and harder to fix if you then apply sealer on top of the sand-crusted pavers, enhancing the rough texture and haze. Of course, when applied properly though, sealer can create a beautiful finish to your polymeric sand project.
Do pavers need a natural border?
Make sure your pavers have a natural or artificial border. If your pavers are set level with the ground, this provides you with a natural border and drainage. If you don't have this, you should install a concrete border or edging to prevent washout at the edges.
Can you put pavers over concrete?
Pavers or stone should be set on crushed concrete, limestone, aggregate, etc, with bedding sand in between. In some cases, thin pavers can be installed over concrete, typically with bedding sand in between to provide a cushion effect and drainage. Installation guidelines vary throughout the country to account for varying soil limitations and climate conditions, as well as usage requirements (vehicular versus pedestrian). If polymeric sand is used in areas without proper drainage, then the water will expose the sand to prolonged periods of wetness and moisture, making it vulnerable to washout. In order for the polymers to harden, the water has to be able to escape.
How to remove polymeric sand from pavers?
How do you remove polymeric sand haze from pavers? The best way to remove polymeric sand from a paver surface is to use a hot water pressure washer at 180°F. The heat will reactivate the polymers in the product and allow the sand to be stripped away. If it is a smaller area use boiling water.
How do I fill cracks in pavers?
Apply Polymeric Sand Over the Pavers. Pour several small heaps of polymeric sand over the patio or walkway. Do not over-apply the sand, because the excess will be hard to remove. You can always add more sand, as needed. The goal is to completely fill the cracks between pavers, without leaving excess sand on the surface. Click to see full answer.
Does polymeric sand work?
Polymeric sand works best when used at full depth. Likewise, does water drain through polymeric sand? Polymeric sand, if installed properly, will harden to lock you pavers in place and create a more effective weed and insect deterent while still allowing water to drain freely.
How to get polymeric sand out of pavers?
Using a broom, begin sweeping the sand into the pavers. Make sure you cover all the empty spaces amongst the pavers. Start from one side and keep doing it until you sweep the sand to the other side of the paver. After you are done with this process, the polymeric sand should be tightly packed between the pavers.
What type of sand is used to seal pavers?
Sand used as a base when laying out the pavers is not the same as the sand used to seal them. Polymeric sand is a special type of sand that is placed between the cracks of the pavers. Once it meets water, the polymers activate and begin to harden, thus sealing off the polymers.
How long does it take for a paver patio to dry?
For most paver patios, sealers are only applied once the surface is completely dry. After that, the sealer takes about 24 hours to settle in and make it appropriate for parking use and so on. Therefore, it is necessary to confirm that there won’t be any rain for the next 24 hours before beginning the process of sealing the pavers. As far as temperature goes, 60-80 Fahrenheit is perfect.
Can you reseal pavers with polymeric sand?
If you are resealing your pavers, it would be best to remove any contaminated sand before putting in new polymeric sand. Contaminated sand can form clumps that may make it difficult for new sand to settle, so it is vital to remove previously applied sand before putting in new sand.
