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.

Can you put sealer over polymeric sand?

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 long do you have to wait to 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.

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 long does polymeric sand last?

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 To Use Polymeric Sand for Pavers

Should I seal the pavers around my pool?

“Do I need to seal my pavers?” The short answer is Yes. Paver sealant is an important maintenance tool to keep paver patios, walkways, driveways and pool decks looking as beautiful as they day they were installed.

Can you apply polymeric sand twice?

First, you run the danger of disturbing your base/shifting your pavers. 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!

Why you should not seal pavers?

Pavers that aren't sealed will be more likely to grow weeds in the joints, they will fade and loose their color from wear and UV breakdown, and because most newer paver sealers include an additive that will harden the joint sand it is less likely that you will have settling or shifting caused by joint sand loss.

Can you pressure 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.

Should I wait to seal pavers?

How long should I wait before sealing my new pavers? Typically 60-90 days. The main reason to wait is so that efflorescence can work its way to the surface and be cleaned off. The more the pavers get wet, the quicker this happens.

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 polymeric sand ruin pavers?

Polymeric sand hardens quickly

Rain activates the polymers before the sand is in the joints which will ruin your hardscape by producing a haze and adhering sand grains to the surface of the pavers.

How often should you water polymeric sand?

Wait about 5 to 10 minutes allowing the water to soak in. It may take 3-4 proper waterings in order to fully activate the polymeric sand. Test for water depth by digging out some sand to make sure it is wet throughout most of the joint. Replace sand.

Why is my polymeric sand not hardening?

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.

Why does polymeric sand fail?

Epic Fail #1: Too much or too little watering.

A polymeric sand installation requires the use of a controlled and methodical watering technique. Using too much water can cause the sand to wash out of the joints. On the contrary, using too little can result in the product not setting up properly.

Do I have to remove old polymeric sand?

But unlike normal sand, the compound hardens very quickly when you expose it to moisture or water. Thus, you must remove polymeric sand from pavers' surface before you finish your project. Still, the polymeric sand usage in paving projects is probably one of the best choices when it comes to sand types for joints.

Does pool coping need to be sealed?

Many types of stone are also subject to staining and/or sun damage, but proper sealing around the pool coping area can minimize or prevent these undesirable results.

Does sealing pavers make them slippery?

Paver sealer products can be slippery if applied too thick, leaving behind a slick film on the surface. Avoid this situation by using thin mil sealers that penetrate deep into the surface and leave a very thin film on the surface. You can also use additives in the sealer itself to increase the friction on the surface.

How long does it take for polymeric sand to harden?

A minimum of 24 hours drying time is required prior to allowing significant foot traffic and 48 hours for vehicular traffic on the paver surface. Polymeric sands are designed to soften and re-heal.

Does polymeric sand erode?

While some formulas for jointing sand have been updated, polymeric sand problems are fast to erode. With over 10 years of studies by Envirobond, we have found that in as little as 120 minutes of rainfall polymeric sand begins to erode. This means you will need to re-do the entire pathway again.
