How do I clean a pool that has a lot of cracks in the concrete?

Jun 27, 2025

Hey there! I'm from a cleaning pool supplier, and today I'm gonna share with you how to clean a pool that has a lot of cracks in the concrete. It can be a real headache, but with the right approach, you can get your pool back in tip - top shape.

Assessing the Damage

First things first, you gotta take a good look at those cracks. Walk around the pool and check out their size, depth, and location. Small hair - line cracks might not be a huge deal, but larger, deeper ones could be a sign of more serious structural issues. You don't want to just start cleaning without knowing what you're dealing with. If the cracks are really bad, it might be a good idea to call in a professional to assess the structural integrity of the pool.

Draining the Pool

Once you've sized up the cracks, it's time to drain the pool. You can use a sub - pump to get the water out. Make sure to drain it slowly to avoid putting too much stress on the already cracked concrete. As the water level goes down, you'll be able to see more of the cracks and any dirt or debris that's stuck in them.

Removing Loose Debris

After the pool is drained, grab a broom and start sweeping out all the loose leaves, twigs, and dirt. You can also use a leaf blower to get into those hard - to - reach corners. This is an important step because if you leave the loose debris in the pool, it can get in the way when you're trying to clean the cracks.

Cleaning the Cracks

Now, this is where the real work begins. For smaller cracks, you can use a wire brush to scrub out the dirt and grime. Make sure to get deep into the crack to remove any built - up sediment. If the cracks are really dirty, you might want to use a pressure washer on a low setting. But be careful not to use too much pressure, or you could make the cracks worse.

For more stubborn dirt in the cracks, you can try using a Bubble Cleaning Machine. This machine uses a stream of bubbles to dislodge dirt and debris from hard - to - reach places. It's a great tool for getting into those narrow cracks and cleaning them thoroughly.

Disinfecting the Pool

Once you've cleaned out all the dirt and debris, it's time to disinfect the pool. You can use a commercial pool disinfectant, but if you're looking for a more natural option, you might want to check out the Garlic Disinfection Tank. Garlic has natural antibacterial and antifungal properties, which can help keep your pool clean and healthy.

Fill a bucket with water and add the recommended amount of disinfectant or garlic solution. Then, use a sponge or a sprayer to apply the solution to the entire surface of the pool, including the cracks. Let it sit for a while to kill any bacteria or algae that might be lurking.

Filling the Cracks

After disinfecting, you need to fill the cracks. You can use a pool crack filler, which is specially designed to withstand the water and chemicals in a pool. Follow the instructions on the filler package carefully. Usually, you'll need to mix the filler, apply it to the crack with a putty knife, and then smooth it out. Make sure to fill the crack completely to prevent water from seeping in and causing further damage.

Refilling the Pool

Once the crack filler has dried, it's time to refill the pool. You can use a garden hose to fill it up. As the water fills the pool, keep an eye on the cracks to make sure the filler is holding up. If you notice any leaks or problems, you might need to go back and re - fill the cracks.

Maintaining the Pool

After you've cleaned and repaired the pool, it's important to keep up with regular maintenance. Test the water chemistry regularly to make sure the pH and chlorine levels are balanced. Skim the surface of the pool daily to remove any leaves or debris. And don't forget to clean the pool filter regularly to keep the water flowing smoothly.
