Polymeric sand cures by drying. 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.
Why is my polymeric sand washing out?
A danger of using too much water too quick creates the possibility of washing away the polymers. Too little water used in the installation process could leave you with a fragile joint. With the first heavy rain-fall, the top layer of hardened sand could break and easily wash out of the joints.
Will water drain through polymeric sand?
It also allows water to permeate through, whereas polymeric sand only lets a small percentage of water to pass through. Since this product allows such a large amount of water to pass through, it is best used in applications where an open graded base is installed that allows water to pass through.
Can you power wash polymeric sand?
You can’t pressure wash and apply polymeric sand on the same day. I should warn you that getting the stain off is a huge problem so it’s best to take the time to avoid it in the first place.
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.
How long should polymeric sand dry before sealing?
If polymeric sand is installed prior to sealing, be sure surface is dry for 24 hours before applying sealer.
Can polymeric sand be reapplied?
Unfortunately with polymeric sand replacement, you can’t just uproot any weeds and top it up. 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!Jul 2, 2019.

Can you use polymeric sand to fill driveway cracks?
Sweep the polymeric joint sand into the cracks between the pavers as you would with other materials. It is recommended that you do this three times to ensure that all of the joints are properly topped off. This will increase weed, insect and water protection.
Does polymeric sand get soft when wet?
Unlike conventional sand it stays in place and remains stable. It softens when wet and firms up when dry to better resist soil movements. Because the sand gets stiff you can expect fewer weeds and less insect damage.
How do you remove hardened polymeric sand?
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.
Will sand under pavers wash away?
Sustaining their beauty requires little work. However, since pavers are exposed to various elements such as rain and wind, the joint sand between pavers may get washed out overtime. Occasional washing can also cause the joint sand to corrode.
Is polymeric sand better than regular sand?
Polymeric sand is also superior to normal sand aside from aesthetics is its longevity. Normal sand will last a while but eventually, it will blow or wash out with the rain and wind, which will leave space for dirt, moss, and weeds to fill in the gaps.
What can I use instead of polymeric sand?
Both white-washed sand and EnviroSAND are excellent alternatives that are cost effective and easy to apply. If you have trouble choosing between polymeric sand alternatives, think about how often you want to touch up your pavers. If you want a bonding that won’t need much for touchups, consider EnviroSAND.
Can I use cement instead of polymeric sand?
Cement is very stable – more stable than most other options. This will not create such a solid surface, so there isn’t as much cement involved. Cement is inexpensive and one of the more prevalent alternatives to polymeric sand. However, it does take a bit more skill to use, as you won’t get a do-over.
Can you use polymeric sand on red brick?
Red clay bricks are a candidate for staining under any conditions, so it’s best to avoid them. Before you apply the sand, you’ll want to make sure the pavers are completely dry most of the way through if you want to avoid staining. It’s important to remove all of the dust created when you put the sand down.
Why is my polymeric sand turning black?
I think the reason this happens is because the sand absorbs water and holds it for too long causing mold and mildew to stain the sand permanently.
How do you remove mold from polymeric sand?
mix a solution of 20-30% bleach in water and add about a tbsp of laundry detergent per gallon of this solution. hose down and/or protect any nearby plant material. spray the solution on the mildewed portion of the patio and let it sit for 5-10 minutes. brush the area with a brush or bristle broom.
Can I use leveling sand between pavers?
You can use All-Purpose/Leveling/Paver sand or Polymeric sand, which permanently adheres the paving stones together. Joint sand can be poured over the pavers, and then swept into the joints.
Does grass grow through 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.
What is the difference between paver sand and leveling sand?
The sand used when building a paver patio or walk is a coarse builder’s sand, with pieces ranging in size from 0.5 mm to 2.0 mm. It may be called C-33, all-purpose or leveling sand. A fine grade of sand, such as joint or play sand, or rock dust is not suitable for laying pavers.
