Remove Efflorescence On Pool Tile And Stone:

how to clean mineral \ calcium deposits on pool tile

Similar to calcium scale which comes from the pool water, efflorescence is calcium lime scale that comes from the grout between tiles or stones placed into a wall or water feature.

To remove tile scale on pools, first scrape off the heavy deposits with a small putty knife, then use a flower watering can to pour of Acid Magic or Instant Liquid Acid, full strength on the front lip of the coping, to run over the tile. Scrub the tile with a stiff brush if possible, then rinse off with a hose within 60 seconds. Repeat if needed, then raise the pool water pH and Alkalinity, now lower from the acid.

What causes this is moisture coming out from behind the tile or stone through the grout or mortar joints and bringing calcium with it. The same process that creates stalagmites.

Sometimes the moisture comes from the pool as shown below. Sealers can be used on the tile to provide an invisible barrier. For larger stone or brick walls above the water, preventing efflorescence may require sealing or redirecting the source of water behind the wall.

You could probably suffer through the summer, for example, and then have them cleaned off when youre not going to use the pool quite so much.

    Unfortunately, that isnt wise.

    Problems With Pool Water Hardness

    In many parts of the country, tap water with hardness levels of 400-800 ppm is not uncommon. High calcium levels can lead to scaling, especially if pH levels are allowed to rise, which produces whitish scale or crystalline deposits, at the water line, inside pipes or all over the pool.

    Excessive water hardness can also come out of solution, precipitating into repeated bouts with cloudy water, or calcium stains as hard minerals mix with dirt and oils.

    Understanding Why And How To Remove Calcium Deposits

    How to Remove Calcium From Pool Tile

    Howand whydoes a pool develop calcium deposits?

    There are a few reasons you may start to notice these stains around your waterline.

    The first is hard water, which can leave behind a calcium residue over time. If you live in a part of the country with hard water, youve probably already noticed this buildup on your faucets, sinks and maybe even tubs.

    The second culprit is heat, which the southern half of the U.S. has in abundance. Not only do high summer temperatures cause pool water to evaporate more, but also they raise the temperature of the water itself.

    When combined with the third culpritthe chemical makeup of your poolthese conditions can lead to calcium deposits. Specifically, if your pool has high pH, high alkalinity and warmer water, calcium scale will begin to form.

    The reason this situation so often happens at the water line is because of evaporation.

    These crystals of calcium may appear as nodules that dot metal and plaster, or they might become crusty deposits that live in the corners of your pool.

    Technically, these are two distinct things. Calcium carbonate, which tends to manifest as a flaky substance on the surface of the pool, and calcium silicate, which is grayish white and harder.

    Either way, theyre not exactly aesthetically pleasing.

    But thats not the worst part. To protect your pool, you need to remove calcium buildup altogether.

    Cleaning Pool Tiles Calcium Deposits With A Pressure Washer

    A great addition to your pool service routine is a pressure washer, which uses intense force to spray water at a fast rate, breaking through calcium hardness that is often difficult to remove.

    An alternative to pressure washing is bead blasting, which applies glass beads at high pressure and does not cause damage.

    If you do not have a pressure washer in your garage, do not worry. Pressure washers are commonly found at your local home improvement store to rent.

    Aim the nozzle at areas with calcium deposits and just above the water level to clear away deposits. Do not wash any tiles that are loose or cracked, as pressure washing may cause more damage.

    Learning how to remove calcium deposits from swimming pool tiles is easier with a pressure washer.

    Faucets And Shower Heads

    When cleaning faucets and showerheads, you can ties a bag of vinegar over the fixture, which helps break down the outside exterior buildup. However, if youre looking to do a more thorough deep clean, then it is advised to remove the faucet aerator or showerhead from its base. Once youve detached it, place the pieces in a bowl with your acid of choice, being mindful of how long you have it sitting and the amount of dilution needed. While this is happening, you can wrap a bag of acid around the rest. After they are done soaking, you can wipe down the area with a cloth.

    Its important to note, that even though vinegar is not as dangerous as other options if you do choose to use it, make sure that you do it at a time where you know your children will not be present. Its better to be safe than sorry!

    Hire A Professional Bead Blaster

    If removing the pool scale doesn’t work with the methods we’ve already listed, you probably have a severe case of pool scaling that needs professional attention.

    You can hire a professional pool company to come to your pool to remove the calcium. This process is called bead blasting and is sometimes called pressure washing.

    This service is different than how you would use a pressure washer to wash your car. Professional companies use a compressor to blast sand, beads or other materials at the pool tile at high speed.

    This scrapes away the buildup quickly. And you don’t have to spend time scrubbing the tile yourself.

    Most companies use magnesium sulfate to blast the calcium off your pool tiles.

    Note, this option can be very expensive. Ideally, you want to remove calcium buildup on your own. And practice good pool maintenance to prevent pool scaling in the future.

    Protecting Your Pool Tile From Calcium Buildup

    by LVad41 | Jul 28, 2019 | Helpful Articles |

    A sparkling clean pool with beautiful, glistening tile can be a refreshing sight to see on a hot day. However, if you dont stay on top of things, youll quickly see that great-looking tile become dull and develop an unsightly white coating.

    This coating is caused by calcium deposits and if neglected, it will continue to get thicker. Eventually, it can become so thick that you wont be able to see the tile underneath it any longer. Learn what causes calcium growth on your pool tile and how to prevent and/or remove it.

    What Causes Calcium to Build-up on Pool Tile?

    Hard water causes the presence of calcium in the pool water to the degree that it can negatively affect the look of the tile. Hard water is water that contains an excessive amount of calcium and magnesium.

    If you have spotted drinking glasses, white film on your faucets, and hard rings around your toilet bowls, then these are other signs you have hard water coming from your taps.

    When the water in your pool touches the tile, the calcium clings to the tiles surface. Faster water evaporation, such as what happens on hotter days, causes the calcium to affect the tile more noticeably.

    What Can You Do to Prevent Calcium Growth on Tile?

    Cloudy water is a sign the water may be too hard. If you look at your pool and notice the water suddenly looks cloudier than normal, test the chemicals even if youve done so recently.
