How Do You Choose Paver Joint Compound?

Many properties today use polymeric sand as a paver joint compound. Jointing sand can be an option, but this material might be susceptible to insects and weeds. Also, keep in mind that not every polymeric sand option on the market offers similar results.

In this section, you’ll learn what to think about when choosing the right paver joint compound or polymeric sand to get the best value for your investment.

Paver Gap Size

It’s important to note that most polymeric sands are ideal for sealing paver joints no larger than an inch. Although it’s still possible to use these jointing compounds on gaps larger than 1-inch, the outcome might become more vulnerable than usual to cracks.

Instead, property owners may choose to use other joint compound solutions aside from polymeric sand to fill fairly big gaps.


Polymeric sands often contain adhesives or polymers to help the product stick to surfaces with the aid of water. Many variants typically use silica as their bonding agents. With this element, the joint compound will possess a sufficient amount of flexibility to help maintain stability to the pavers.

Take note that some polymeric sand manufacturers may also blend silica with other glues and chemical binders. In turn, certain options might not provide as much flexibility to pavers as compared with other options.


Aside from its functional properties, buyers should also choose between different colored paver joint compounds. The aesthetic qualities of these products typically come from mixing different pigments of polymeric sands.

Interested customers can choose among colors like black, brown, green, and white. It’s ideal to select a color that can go well with the paver’s material. For example, black, cream, or gray-colored joint compounds are good complementary colors that go with red brick pavers.


Cement in a paver joint compound can help enhance the product’s durability. It may also cause hazing around the pavers’ perimeter, creating a unique design. Also called polyhaze, this appearance may or may not be suitable for every paver design.

Therefore, choose joint compounds with cement if you want hazing in your pavers. Otherwise, stay away from products with that component if you're not too keen on polyhaze.

Drying Period

Paver joint compounds are still quite vulnerable within 12 hours after the application. Installers should also consider putting protection over the product within this timeframe to safeguard it from the elements like rain.

Generally, it should also take about 24 hours for a paver joint compound to dry. Some formulations may dry faster or longer than others.

Check the product’s label or online description to know the suitable time for a particular joint compound to dry and cure. Remember, fast-curing paver joint compounds don’t mean they’re better in every aspect than their slow-curing counterparts.

One of the primary determinants that influence whether a buyer will proceed with purchasing a specific paver joint compound is the price. Many brands will price their joint compounds within the $20 to $40 range.

Purchasers should consult their budgets while thinking of the costs of their preferred joint compounds. Additionally, the product should have a fairly long lifespan to prevent property owners from buying and applying these compounds on their pavers frequently.
