How To Prevent Grass From Growing Between Pavers – 6 Ways

Cut The Grass

When it comes to how to prevent grass from growing between brick pavers, the first thing to do is to remove the grass. You can choose to pick up the weed by hand, which is more flexible and inexpensive. But this method is also time-consuming and exhaustive, especially when your slabs are too large. 

Before removing the grass, put on garden gloves to protect your hands from sharp branches and soil. The glove will also keep your hand dry and safe from the small insects living inside the bushes. Wear a garden boot to protect your leg as the garden is wet and dirty.

Remember to prepare a troller or wastebasket to contain the grass. Doing this helps you save a lot of time collecting the removed weeds on your slabs. If the cracks are too narrow, you can use a small knife to remove the grass.

Using Natural Remedies

This is the best way to keep grass from growing between paver stones. If you don’t have time to spend hours picking up the grass, consider using natural remedies to kill the weed. This method is safe and doesn’t affect the environment compared to chemical treatments. 

One honorable natural remedy we recommend is baking soda. Baking soda is very effective in absorbing moisture. When applying this powder to weed, it will soak up all the moisture and fluid in the grass. Also, the salt in baking soda will slowly kill the unwelcome guests. 

This ingredient is a popular product sold in virtually every grocery store at cheap prices. If you can’t put your hands on baking soda, try using the natural eating salt in your kitchen. Mix the salt with water in the ratio of 1:3 and apply the substance to the grass. 

Some other effective natural remedies are boiling water and white vinegar. They are all inexpensive and easy to find.

Pressure Wash

Pressure wash your slabs after picking up the growing weed in the cracks. Pressure washing will remove the excessive dead weeds and clean the compacted soil deep in the cracks between brick pavers. Your yard will be clean of grass roots and have a more beautiful lawn at the same time. 

It is best to use a surface cleaner with low water pressure to clean the pavers. A strong pressure washer can ruin your soil and damage your paver structure, notably brick pavers. 

After washing, the water will remove all the weed seeds lying deeply in the soil. You no longer have to worry about the weed growing back after a long time. 

Seal The Paver

The last step to prevent the grass from growing between pavers is to seal the patio stones. 

The seal layer will cover all the land of the paver, so grass between pavers and nearby plants won’t have space to grow. You can purchase high-quality sealers in a convenient store or online shopping at affordable prices.

Apply Polymeric Sand

The latest polymeric sand is a combination of sand and binding compounds. Polymeric sand protects the slabs against erosion and insect infestation with polymeric sand. The joints between the slabs will become more flexible and solid by applying the sand layer. 

First, fill the cracks with polymeric sand by spreading the sand equally in every little space. Then use a hose to spray water on the polymeric sand. After a short period, the sand will become hard like cement.

Wear safety glass in the process of sweeping the sand. It is very dangerous if the sand dust reaches your eyes and nose. Ensure that the surface of the slabs is dry and clean before applying the polymeric sand.  


A clean paver will make your home more welcoming and neat. And keeping it free of nasty weeds is of great help.
