Polymeric sand can last up to 10 years before replacement is necessary. However, certain manufacturers claim some products can last up to 15 years.
How long can you keep polymeric sand?
Polymeric sand lasts for 10 years. High-quality polymeric sand can last for 15 years. Installing polymeric sand the right way ensures that it lasts for a decade. Problems during the curing process can decrease its lifespan.
How do you maintain polymeric sand?
Polymeric sand can be kept in its original packaging, in a dry place and away from UV rays. Bags may be stored outside if they are properly protected with an opaque and waterproof tarp.
Can polymeric sand be reapplied?
Unfortunately with polymeric sand replacement, you can’t just uproot any weeds and top it up. You have to completely remove all the pre-existing sand in the joints and start fresh. Secondly, you will have to wait a day while the surface dries before you can reapply your new sand.
Does polymeric sand harden like concrete?
Polymeric sand cures by drying. And in order to fully set, it needs to dry out completely. If your polymeric sand didn’t harden up, it’s pretty much guaranteed there’s a moisture issue. If the joints remain wet after the installation, they will remain soft until they dry.
When should you not use polymeric sand?
#6 – Too Narrow or Too Wide Joints The sand is simply pushed out of the joints. This is why we don’t recommend using polymeric sand on extremely narrow joints. Similarly, too-wide joints can lead to washout, because they allow too much water flow during the activation process.
Can you pressure wash polymeric sand?
Yes, you can use a pressure washer but strictly if necessary. If it’s not possible to remove the hardened polymeric sand after a few days washing the surface, then you can bring on the “big guns.” The essential when using pressure wash is not to remove the polymeric sand between the joints.
Does polymeric sand need to be sealed?
If us- ing polymeric sand, you can install it after the sealer application has properly cured for 24 – 48 hours. If polymeric sand is installed prior to sealing, be sure surface is dry for 24 hours before applying sealer.
How do you compact polymeric sand without a compactor?

Should you seal polymeric sand?
how long after installing polymeric sand can pavers be sealed? Traditionally, concrete paver manufacturers have recommended waiting at least 90 days after polymeric sand installation to apply a protective sealant to a paver surface.
Will water drain through polymeric sand?
Installing polymeric sand involves more than just sweeping and watering. 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.
Can ants get through polymeric sand?
Polymeric sand hardens in place when exposed to moisture so the sand particles bond together and are more resistant to ants mining through it.
What can I use instead of polymeric sand?
Builder’s sand is the most common replacement for polymeric sand, as it is easy to access and not expensive. It is used heavily in construction projects, hence its name. Because this sand is very coarse, you will need to use it regularly. You’ll have to reapply it for years as it settles.
What happens if polymeric sand gets rained on?
After installation, a hard rain on polymeric sand that has not fully set up could result in polymeric sand all over the top of the pavers. However, once water is applied, any remaining polymeric sand particles will harden and remain on the surface resulting in an unhappy customer.
Is there a difference between jointing sand and polymeric sand?
Polymeric sand is a material used to fill paver joints, the empty spaces found between each paver, tile or natural stone. Jointing sand is made up of fine grains, to which manufacturers add a mixture of specific additive particles.
How far does a bag of polymeric sand go?
When filling small gaps, a 50lb bag of polymeric sand will usually cover 75-100 ft2. When filling wide gaps of 1/4″ to 3/8″ a 50lb bag will usually cover 30-60 ft2.
Can grass grow in polymeric sand?
When properly installed polymeric sand is very weed resistant. When you allow organic material like grass clippings, dirt, mulch etc… to sit in the joints that will break down into an ideal place for a weed seed to get caught p and start growing.

Poly Sand Haze Tips If poly sand haze has transpired on the surface, it must be cleaned with an acid-based cleaner. Sometimes vinegar can be used unless the poly sand haze is severe.
Can you powerwash a patio with polymeric sand?
Yes, they can be powerwashed but only if you take the time to do it right and follow the directions to a tee. The joints should be 1/4″ wide and as deep as the pavers. Which means you have to remove all the old sand. After applying the jointing sand, compacting is advised and then adding more sand.
