Concrete pavers are a popular choice for patios, walkways, and driveways due to their durability and low maintenance. However, over time and under poor maintenance, they can be susceptible to the growth of moss, which can make the surface slippery and unsightly. While there are chemical moss killers available on the market, many people prefer to use natural methods to clean their concrete pavers. What is the best natural moss killer for concrete pavers, though?

In this article, we will discuss some effective housemade killers you can be applying to your concrete pavers without further damage.

White Vinegar

Vinegar is a natural and inexpensive way to kill moss on concrete pavers. The acetic acid in white vinegar is a natural weed killer and can also kill moss. Beware, though: don’t overuse it, because it’s also abrasive and can make your pavers fade out!

To use vinegar as a moss killer, mix equal parts of water and vinegar in a spray bottle. Spray the solution on the affected areas and let it sit for 30 minutes to an hour. Then, scrub the moss off the pavers with a stiff-bristled brush. Rinse the area with water to remove any remaining vinegar solution.

Baking Soda

Baking soda is another natural moss killer that can be used on concrete pavers. It is effective in killing moss – as it creates an alkaline environment in which moss cannot survive. To use baking soda as a moss killer, mix it with water to make a paste. Apply the paste on the affected areas and let it sit for a few hours or overnight. Then, scrub the moss off the pavers with a stiff-bristled brush. Rinse the area with water to remove any remaining baking soda paste.

Salt

Salt is a natural substance that can be used to kill moss on concrete pavers. It works by drawing moisture out of the moss and killing it. To use salt as a moss killer, mix it with water to make a solution. Spray the solution on the affected areas and let it sit for a few hours. Then, scrub the moss off the pavers with a stiff-bristled brush. Rinse the area with water to remove any remaining salt solution.

Boiling Water

Boiling water is a natural and easy way to kill moss on concrete pavers. The high temperature of the water can kill the moss without harming the pavers. To use boiling water as a moss killer, simply pour boiling water over the affected areas. Let the water cool for a few minutes, then scrub the moss off the pavers with a stiff-bristled brush. Rinse the area with water to remove any remaining moss.

Sunlight

Sunlight is a natural way to kill moss on concrete pavers. Moss thrives in damp and shady areas, so exposing the pavers to sunlight can help dry out the moss and kill it. To use sunlight as a moss killer, remove any debris or leaves from the pavers to allow more sunlight to reach the surface. You can also trim any nearby trees or shrubs that are casting shade on the pavers.

Substances and Damaging Chemicals to Avoid

While there are several natural and effective ways to kill moss on concrete pavers, it is important to avoid using substances or chemicals that can damage the pavers or harm the environment. Here are some substances and damaging chemicals that you should avoid when trying to kill moss on concrete pavers:

Bleach

Bleach is a commonly used product for killing moss, but it should not be used on concrete pavers – or on any other hardscape material, for that matter. Bleach can damage the surface of the pavers and cause them to become discolored or pitted. Additionally, bleach is harmful to the environment and can harm surrounding plants and wildlife.

Copper Sulfate

Copper sulfate is another chemical that is sometimes used to kill moss, but it should not be used on concrete pavers. This substance can cause damage to the surface of the pavers and can also leach into the soil, harming nature.

Glyphosate

Glyphosate is a herbicide that should never be used to kill weeds and moss. It can damage the surface of the pavers and can also leach into the soil, much like copper sulfate.
