How To Repair Plaster In A Pool Whether Its Empty Or Full

How to repair cracks in concrete pools.

Its time to get plastered! No, not like that. Were talking about pool plaster repair here. No matter how well you care for your concrete pool, it will eventually develop cracks here and there. Or the plaster may become loose in spots and need to be replaced. Or maybe someone was roughhousing in the pool again, and gouged the wall with the lightsaber you told them to leave in the house.

Whatever the cause, you dont want to leave those damaged spots for too long, or theyll only get bigger. Before you know it, you could have a leak on your hands. But dont worry. Repairing the plaster in your pool isnt as difficult as it may sound.

How Often Should I Replaster My Pool

This is entirely up to you and depends on the condition of your pool. All materials, including plaster, will deteriorate and show signs of wear as they age. On average, you should get 15 years usage from a plaster lined pool before you need to renovate it. If you have neglected your pool for a few years and it has had a few algae blooms, unbalanced water chemistry or other issues maybe it needs replastering sooner.

If you are planning to sell your home then replastering an old pool may add extra value to the house or at least make it more presentable for sale.

Do I Have To Acid Wash My Pool Before Painting

Yes. Your pool surfaces must be clean, flat and dry so that pool paint will adhere to the plaster. I highly recommend an acid wash to remove all dust and dirt before painting.

Some people recommend lightly sanding the plaster surface to remove the polished smoothness which gives the paint better adhesion. Make sure you wash the surface afterwards to remove the dust. Please wear a mask when you do this to prevent breathing in the fine plaster dust particles.

Pool Plaster Repair: Patching

It could be more than a crack or small spot that needs to be fixed. Sometimes, plaster will bubble, or become loose. Youll have to empty the pool for this repair.

Follow detailed instructions for how to drain a pool to keep your pool from popping.

  • Put on your safety goggles, ear protection, and heavy-duty work gloves, and be sure to wear long pants, long sleeves, and closed-toe shoes.
  • Use the hammer and masonry chisel to remove spots of obviously loose plaster.
  • Use the wooden pole to tap around the pool floor, and listen for a hollow sound, which indicates more loose plaster. If you find any, chisel them up as well.
  • Clear away the plaster youve removed.
  • Use the chisel to create a few divots in the surface of the area youll be patching. This will help the new plaster adhere to the surface.
  • Apply an acid wash to the surface youll be working on.
  • Measure the surface area youre going to patch so you can prepare enough pool plaster.
  • Mix the plaster to the consistency of peanut butterthick enough to stay in place, but not so thick you cant easily spread it.
  • Add cement dye, if necessary, to match the current plaster color.
  • Dab the surface to be repaired with a wet grouting sponge, or spray the surface with a fine mist of water.
  • Use the pool trowel to apply the plaster, pushing it into the divots you made with the chisel, as well as any corners.
  • Push out any air bubbles and smooth the surface with the trowel, feathering the edges into the surrounding pool surface.
  • What Is Pool Plaster Delamination

    How to fix cracks in pool plaster with concrete plaster ...

    Youve probably seen pool plaster delamination in a pool at some point without knowing what it was. Well talk about the causes in the next section, but first, lets talk about how to identify delamination.

    Once you know what to look for, the outward signs are unmistakable: blisters or bubbles that form on the surface of the swimming pool.

    These blisters or bubbles are calcium nodules or small buildups of calcium carbonate on the pool surface. Theyre easy to recognize because of their strong resemblance to bird droppings.

    Calcium nodules are usually round, and they look somewhat like volcanoes when they form on horizontal surfaces. On vertical surfaces, however, they tend to look more like drips or stalactites.

    Delamination can occur in small areas two to three inches in diameter, or it can form in wide expanses of three to four feet, or even more.

    While delamination formations are generally easy to identify based on the features weve already mentioned, another distinguishing characteristic is the color.

    Delaminated areas are usually white, though they do sometimes become grey over time. If they absorb other elements, they can be different colors as well, but generally, theyre white.

    Homes that still have plaster walls in prime condition are often valued by homeowners and homebuyers alike. They are beautiful, solid, and especially good at soundproofing rooms. But plaster walls respond to inevitable foundation shifts and climatic changes. They can begin to crack. Everyday life, with its bumps and bangs, also takes its toll on plaster walls. And certain key areas, such as above and beside doorways and windows, are classic areas of cracking. Nearly all homes with plaster walls will eventually develop window and door cracks.

    Though they may look scary, your cracked plaster walls are not beyond repair. You do not even need a special plaster repair kit. One way to quickly fix cracked plaster walls involves basic drywall tools and materials that you can buy at any home improvement store.

    Cracking Due To Rebound

    Material that flys off or bounces of the rebar and existing concrete is often called Rebound It has a higher concentration of sand and less cement than the original mix, thus it is weaker than the original material. Contractors will often reuse this rebound material to save material and labor. They may use it on the bottom of the pool, in the step entry areas of the pool, or the seating benches or ledges in the pool thats below water.

    This practice of poor workmanship may result in weakened areas or cracks at times. If you look closely you may see crack evidence in the entry step area of many pools. When the rebound caused cracks are at the entry step area, they do not always go through the entire shell, therefor there is no leak.

    Delamination is another issue with rebound materials, for they do not always bond fully with other gunite or shotcrete that has been shot. The bonding problem relates to the fact that rebound material has less cement and more aggregate and sand.

    The decision to paint or replaster your pool is a personal and financial choice. Painting will be the least expensive option but will last less than a new plaster lining. All pools need maintenance and eventually renovation so if you donât want to have to paint the pool again in the future I recommend replastering it. With paint you will be repainting every 5 to 10 years but with plaster you will replaster every 10 to 20 years depending on how you have looked after your pool.

    Fix Minor Surface Cracks And Punctures In A Vinyl Liner Pool With A Vinyl Patch

    Minor cracks and tears in a vinyl liner pool can easily be repaired with a vinyl patch kit. Since most kits can be repaired underwater, you wont need to drain your pool. To fix punctures in your vinyl liner pool, first cut the vinyl patch in a circle or oval shape. The size of the path should be at least ½ inch bigger than the size of the crack or puncture.

    Next, put some vinyl glue onto the patch and fold it together for about three minutes. After that, unfold the patch and put it on the crack or puncture. Seal it by rubbing out all the air. Let it sit for around 10 minutes and rub again to ensure complete coverage.

    Are Cracks In Pool Plaster Normal

    Owning a pool comes with maintenance and sometimes repairs. When you own an in-ground pool, you need to be aware of the condition of the plaster in your pool. Over time, you may notice some cracks in the plaster leading you to wonder are cracks in pool plaster normal?

    This may especially be the case if youre new to owning a pool or if its the first time youve ever noticed cracks. Lets take a closer look at what causes pools to crack and what you can do to fix them.

    How To Prevent Pool Stains:

    • Keep leaves and debris out of your pool
    • Vacuum the dirt as often as necessary, and dont let it sit on the floor for long periods
    • Brush the plaster surface once a week
    • Acid wash your pool every few years to refresh the plaster and keep the stains to a minimum
    • Regularly test for metals in the water if youve had problems with metal staining in the past

    Plaster is the traditional surface choice for concrete pools, but it can be a lot of work. Aggregate is a little bit more durable, and tile is the most durable option . Keep in mind that these are both more expensive than plaster, and your pool will still need to be resurfaced about every ten years or so no matter which option you choose.

    If youre still shopping around for an inground pool, you might want to consider a high-quality fiberglass pool. The gelcoat surface of a fiberglass pool is smooth to the touch and, if made well, can last the entire lifetime of the pool.

    Polish To Repair Swimming Pool Plaster

    The option which I prefer is to polish the plaster surface instead of painting. If your plaster is still reasonably thick and in good condition but just has some staining, spots, pitting or hairline cracking you can use an angle grinder with a fine fibreglass flap disk to polish the plaster back to new again.

    The grinding disk will remove a fraction of a millimeter of plaster to remove stains, dullness and any other minor imperfections to bring new life back into your pool. Wear a mask and wash down the pool to clean out the dust before refilling. This is the cheapest and easiest option that will give you at least another 5 years of usage before further renovation.

    Adding The Finishing Touches

    After letting your last layer of plaster dry completely, paint over the area with some pool paint to make it blend more evenly with the rest of your pool. We recommend starting with two coats of paint, let it dry, and see if you need more. After the paint is dry, you should be ready to refill your pool. Dont re-enter your pool until the water is balanced and all work areas are clear of plaster dust.

    Gunite Pool Repair: How To Fix Your Pool

    Gunite is a durable and highly adaptable material often used to build swimming pools. While many people believe gunite and shortcrete are different, theyre essentially the same both being a type of sprayed concrete. Because of this, many people also refer to gunite pools as concrete pools. Pool installers make a special mix of cement, sand and water to create gunite. This mixture is then evenly applied to the foundation of the pool to line it. If youve noticed a leak on your pool, it might be time for some gunite pool repair at your property.

    Crack In Pool Plaster

    If you only have some minor chips, cracks or flaking in the plaster nearer the surface of the pool then you may get away with not draining the water.

    You will need a mask and snorkel to see underwater. Chip out the damaged plaster and refill with new plaster. Follow the instructions as for repairing an emptied pool to chip out the damaged plaster. The plaster will fall to the bottom and needs to be vacuumed later.

    There are two options as to what material you use to make the repair.


    Buy the waterproof plaster for use underwater. Mix up a batch following the manufacturerâs instructions on the label and patch the repair sites.

    Please wear protective gloves and glasses.

    The best product comes with two strips of putty-like material that you mix together to form the patching compound. Once mixed it will dry rock hard very quickly so work fast to fill the holes or cracks and smooth it off with a trowel. You normally only have 10 minutes maximum before it begins to set hard. After a few hours it will be rock solid.
