How to Seal Concrete Waterfall: Sealing Guide
Here are the items that you are going to need:
- A concrete sealer
- A water hose
- A bucket
- A sponge
- A brush
Preparing the Concrete
Before you begin, it is important to make sure that the concrete is clean and free of any dirt or debris. You can do this by power washing the concrete or by scrubbing it with a brush and soapy water. Once the concrete is clean, allow it to dry completely before proceeding to the next step.
Applying the Sealer
Once the concrete is dry, you’re ready to apply the sealer. Begin by mixing the sealer according to the manufacturer’s instructions. Once the sealer is mixed, pour it into a bucket and use a sponge to apply it to the concrete. Work in small sections, and be sure to evenly coat the entire surface.
Letting the Sealer Dry
After you have applied the sealer, you will need to let it dry for at least 24 hours before using the waterfall. During this time, it is important to keep children and pets away from the area as the fumes from the sealer can be harmful.
Once the sealer has dried, you’re ready to add water to your waterfall. Begin by attaching a water hose to a faucet or outdoor spigot. Then, position the hose so that water flows into the top of your waterfall and allow it to flow until the basin is full.
Adjusting the Flow Rate
If you want to adjust the flow rate of your waterfall, you can do so by adjusting the knob on your water hose. If you want a slower flow, turn the knob clockwise; if you want a faster flow, turn it counterclockwise. Experiment until you find a flow rate that you’re happy with.
Enjoying Your Waterfall.
Once your waterfall is flowing at your desired rate, sit back and enjoy. You can use your waterfall as a relaxing backdrop for reading or entertaining guests in your backyard oasis.
Does Concrete Need To Be Sealed?
The answer to this question is twofold. No, you do not need to seal concrete waterfalls. Sealing the concrete can actually trap moisture and lead to problems down the road. Even though a concrete wall can get wet, water is less likely to accumulate on it than it does on a flat surface, so concrete walls do not require sealing as much.
Even though concrete does not necessarily need to be waterproofed, in some cases, it is a substantial benefit and highly advisable. Sealing concrete surfaces like a concrete walkway or patio is a smart idea.

Why Should You Not Seal Concrete Waterfall: Some Reason
Sealing Concrete Waterfall Can Decrease Its Aesthetic Appeal
One of the primary reasons why you should not seal concrete waterfall is because it can impact the aesthetics of the feature. An unsealed concrete waterfall is typically more visually appealing than a sealed concrete waterfall. Sealing concrete waterfall can change its natural look and feel, which may not be what you are looking for.
When concrete is sealed, it changes the appearance of the waterfall, and it takes on a glossy finish that can reflect light in a way that is unnatural and unappealing. Sealed concrete can change the color of the waterfall, making it appear artificial. The sealant will also make the concrete appear dull and lifeless, which can take away from the overall beauty of the waterfall.
Sealing Waterfall Can Increase Maintenance Requirements
Maintenance is another reason not to seal concrete waterfalls. Sealed concrete waterfalls require more maintenance than unsealed waterfalls. In order to keep them looking their best, you will need to regularly clean and reseal the surfaces. This can be a time consuming and expensive process in the long term.
Sealing a concrete waterfall can make it more difficult to clean and can also trap moss and alga. An unsealed concrete waterfall is much easier to maintain and keep clean. You will also need to be careful when cleaning sealed concrete, as using harsh chemicals or cleaners can damage the sealant.
If the sealant begins to wear away, it can be challenging to apply a new coat evenly. A sealant needs to be reapplied every few years in order to maintain its effectiveness, and any cracks or chips in the sealant will be required to be repaired immediately.
When a concrete waterfall is sealed, it is not as durable as an unsealed concrete waterfall. Sealing concrete waterproofs it and makes it more susceptible to cracking and chipping. The unsealed concrete waterfall is much more resistant to damage and will last longer over time. If water gets under the sealant, it can cause cracks and other damage to the concrete. Chemicals such as chlorine can also cause damage to sealed concrete. If sealed concrete becomes damaged, it can be difficult to repair. The sealant will need to be removed before any repairs can be made.
Sealing Concrete Waterfall Can Be Harmful to Your Health
Another reason why it is not a good idea to seal concrete waterfalls is that it may be toxic and risky to your health. There are also health concerns associated with sealing concrete waterfalls. The chemicals in the sealant can cause skin irritation and respiratory problems in some people. These chemicals can off gas into the air, which can have a harmful outcome to your health if you inhale them on a regular basis
When concrete is sealed, it creates a barrier that prevents air and moisture from escaping. This can lead to moss and alga growth, which can cause respiratory problems and other health issues. The chemicals used to seal concrete can be toxic if they are inhaled or come into contact with your skin.
Why Is It Needed to Seal Concrete Waterfall?
The use of applying a sealer helps to preserve and maintain the appearance and durability of the concrete while enhancing its natural color. The sealer will block water from seeping into the concrete by forming beads of it on the surface.
Using this technique helps concrete perform better and last longer, particularly in winter. And a decent and suitable sealer can have nonslip properties, which is ideal for near a pool. This technique even helps fight stains by forming a thin membrane barrier between the stain and concrete.
The use of a sealant is great at protecting against sun damage and discoloration. Once the concrete surfaces have dried and hardened, applying a sealant helps prevent further deterioration, stains, and corrosion.
Due to the porous nature of concrete, it is prone to absorbing water and other substances. When the concrete waterfall is sealed, it closes up the openings and prevents any thaw damage or future freeze to your concrete waterfall, which in the long run can cause cracks.
If you have decided to seal the concrete waterfall, make sure it is a high quality sealer that will not yellow or discolor the concrete. You also want to make sure the sealer is rated for exterior use. If you do decide to seal your concrete waterfall, be sure to follow the instructions on the product label.
