Remove Calcium Deposits From Tiles & Plaster

Calcium scale can ruin the aesthetic of the pool and it can be very unsightly. The white to gray stain can form when the calcium or pH levels are imbalanced. Although it’s very difficult to remove, you can get rid of them.

In general, it’s good to know that the scale can form mostly during summer. This is because of evaporation increases during this season. The crystals will form on the surface of plaster and tiles and they can look like crusty deposits. Nobody wants to enter a pool where there crusty deposits on the sides of the pool.

In addition to this, it’s good to know that there can be two types of calcium buildup. There are calcium carbonate and calcium silicate. In order to find out what scale you have, you need to place few drops of Muriatic acid on the deposit. Calcium carbonate will form foam and calcium silicate will not react at all.

Prevention

It’s fairly easy to ensure that you do not develop calcium deposit if you care about your pool. Maintenance is key. You have to ensure that the alkalinity and pH levels are constant throughout the season and the temperature of the water doesn’t exceed the limit. It’s easier to maintain them to normal levels than to deal with them whenever they go over the top. There are some additional things you can also do:

  • Use a sequestering agent. This formula will work by keeping it locked. It will not be able to react with the other agents in the water. It will not form scaling because it’s kept away.
  • Avoid using calcium hypochlorite shock. You will make the situation far worse. In fact, you will only raise the levels of it in the pool. The more you add to this chemical, the harder it will be to remove it.
  • Use the Langelier Saturation Index. All you will need to do is take 5 water tests, and then the LSI will do the maths for you. It will calculate the pool’s propensity of scale. Therefore, whatever results you get, you need to balance them.

How to Remove Scale

If the scale isn’t big and doesn’t take up a lot of surfaces, you can use a sponge and a lot of hands work to take it off. A pumice stone will help you as it makes scrubbing much easier. In order to prevent the surface from getting scratched, you need to ensure the area is soaking wet and that you apply a lot of elbow grease.

In addition to this, you can also purchase a stain eraser from many stores. Attach it to a telepole in order to position it into a specific area and allow some time for it to react with the formula. After that, you can usually wipe it off with a sponge.

Nonetheless, for tiles and plaster, there are two different methods. Follow the instructions accordingly and you will be able to enjoy a stress-free summer.

Remove From Pool Tile

  • Step 1. Reduce the water level below the tile.
  • Step 2. Prepare the acid solution. In this situation, it all depends on what you prefer to use. We advise you that you spend a little more money on a good solution as the formula is the key part to remove the scale forever.
  • Step 3. Apply the solution with a sponge or a brush. Please remember that a thick brush is much more helpful than a sponge. However, don’t despair if you haven’t got one. A sponge will get you the same results as a brush or putty knife, it will just take more effort to get there.
  • Step 4. Wait for 1 minute, then rinse with water. If you are not happy with the results, repeat the process until you get the results you want.

If you have tiles, it’s very important that you have patience. Do not over-scrub or risk getting them scratch as you do not want to deal with that either. It’s best that you try out different solutions until you get to the one that meets your standards.

Remove From Pool Plaster

  • Step 1. Drain the entire pool.
  • Step 2. Acid washes the whole pool with a pressure wash. This is to ensure that the whole surface is clean. The reason being that pool plaster tend to have calcium deposits everywhere, it’s just harder to spot as everything is white.
  • Step 3. In case the deposits have lowered in size, you can use a pumice stone or pool stone. Be aware that it requires a lot of scrubbing and hard work to get it off. You may need few hours.

In this situation, you are best advised to hire a professional. The company will use a pressure washer and the scale will be blasted off. Nonetheless, if you want the cheaper version of this solution, you can do it yourself. Ensure that the formula you are using on the scale is of high-quality and the washer is on full blast. It may take you the whole day to get the pool looking like normal again.
