Is there a way to prevent them from sprouting in the first place?

Here at Outback Landscape, we have the skills, tools and knowledge to design and install patios that stand the test of time — and stand up to tenacious weeds.
Step 1: Grab Your Screwdriver
Before applying sealant, you need to re-fill the spaces between pavers with sand.
Keep in mind, sealing your pavers protects them from weather and moisture, preventing mold, mildew, algae, and moss, as well as keeping your pavers from weathering and cracking. While sealing your pavers isn’t necessary to keep weeds out, it is great for the overall look and maintenance of your pavers.
A kettle of boiling water is one of the simplest weed-killing devices there is. Simply pour boiling water on the unwanted plants coming up through your pavers. A few applications should kill them, but similar to vinegar, the roots will most likely remain.
However, sealing your pavers is a multi-step job. If your main goal is to stop weeds from growing between your pavers, you may opt instead to use polymeric joint sand between your pavers and stop there. This joint stabilizer hardens when you add water, and doesn’t require the use of sealant. When you use polymeric sand in the seams between pavers, you will put a stop to those weeds without sealing your pavers.
5 Easy Ways to Prevent Weeds From Growing Between Pavers and Patio Stones
A homemade weed killer made from white vinegar and a quarter-teaspoon of dish soap in a spray bottle will kill weed leaves coming up through pavers. Vinegar destroys the leaf cuticle, killing the plant. The dish soap adds viscosity, which helps the white vinegar cling to leaves and do its work.
When re-sealing, follow the same steps that you would in the initial sealing process. This is the best way to maintain your pavers and make sure weeds don’t invade.
Sweep excess polymeric sand into the seams between the pavers. Joint sand should be ⅛ inch below the level of the pavers. Add or remove joint sand as necessary to achieve this height. Then, using a rubber mallet or tamper, tap the pavers. This will help settle the joint sand into the cracks, creating a more compact and weed-resistant final product.
Follow the directions on your sealant of choice and apply it to your pavers. It’s a good idea to test a small area first, to make sure the sealant doesn’t discolor your pavers.
