F.A.Q.
We understand that purchasing a pool cover naturally raises many questions. That’s why we’ve gathered here the answers to the most frequently asked questions about the Coverseal, its installation, maintenance, and much more.
You’ll find them below, organised by theme or accessible through the quick search feature.
General information
No. All Coverseal models offer the same level of excellence in terms of safety, protection and reliability. The difference lies in the way they are used and the options that distinguish them, in order to meet the expectations and lifestyle of each owner. Our Automatic model is easily controlled from a smartphone for maximum comfort and quick opening/closing. Our Semi-Automatic model, meanwhile, is equipped with a portable control unit that can be recharged from an electrical outlet, offering up to fifteen cycles of use before recharging.
Coverseal pool covers fit almost any pool model, regardless of shape or size. However, some parameters may prevent the installation of a Coverseal pool guard.
– A concave support
– A slope towards the inside of the pool
– Certain supports (hollow composite, slope > 4%, etc.)
Our technical department will be happy to assist you and answer your questions.
Yes, a Coverseal can be installed on most surfaces, including concrete, provided that it is in good condition and stable enough to ensure long-lasting anchoring. We offer two types of rail to guarantee optimal installation: the standard rail and the all-surface rail. Depending on the levelness of your concrete surface, our technical team will determine the most suitable option to maximise the strength and performance of your installation over time.
Yes, a Coverseal can be installed on most supports, including wood, provided that it is sufficiently durable and solidly anchored so as not to deform or move over time. We offer two types of rails to ensure perfect fastening: the standard rail and the all-surface rail. Depending on the nature and density of your anchoring surface, our technical team will select the most suitable solution to ensure the longevity and performance of your installation.
Yes, it is entirely possible to install a Coverseal on clinkers, provided that they are properly laid, stable and show no signs of movement or subsidence. To ensure safe and long-lasting anchoring, we offer two rail systems: the standard rail and the all-surface rail. The latter has been specifically designed for irregular or uneven surfaces such as clinkers, ensuring both the performance and durability of your installation.
Yes, it is possible to install a Coverseal on coping stones, provided that they are securely fixed and offer a stable, even surface. This ensures a solid and lasting hold for the fixings over time. In such cases, when fitted on coping stones, the all-surface rail is recommended to guarantee a safe and durable installation.
Yes, installing a Coverseal on a natural stone surface is perfectly feasible, provided that the slabs are securely fixed and stable. This ensures firm anchoring and prevents any movement that could affect the fixings over time. We offer two types of rail to suit your decking surface: the standard rail, ideal for flat areas, and the all-surface rail, recommended for uneven finishes. Our technical teams will determine the most appropriate solution to ensure the robustness and longevity of your installation.
Yes, a Coverseal can be installed on solid composite decking, provided that the structure is stable and securely fixed to prevent any deformation over time. We offer two rail options, standard and all-surface, to suit the characteristics of your installation. In the specific case of a solid composite deck, the all-surface rail is recommended to ensure optimal and long-lasting attachment.
Yes, installing a Coverseal on stoneware is perfectly possible, provided that the surface is stable and laid in such a way as to prevent any movement or detachment over time. We offer two rail systems, standard and all-surface, to ensure secure and long-lasting anchoring. Depending on the levelness of your tiling, our technical team will select the most appropriate solution to guarantee the strength and durability of your cover.
Yes, our product is designed and manufactured to the highest safety standards. However, it is a safety cover, not a play area. We therefore strongly advise against allowing children, adults or pets to walk on the membrane, use it as a trampoline, or treat the trim as a diving board, as this could cause damage.
Like any material exposed to UV, the membrane may undergo slight discolouration over time. This phenomenon, although natural, will be more pronounced on dark membranes.
The trim of the cover, meanwhile, is powder-coated. The paint is, therefore, very resistant over the long term and suited to the environment of the pool. However, just like a car body, there can be slight discolouration with sun exposure. It is also possible to find trims with more specific finishes, namely a “mirror effect” or “metal effect”. In this case, the trim is made using composite panels. It is also a product that will go through the years without losing its quality.
Unlike other protection products, the Coverseal pool cover does not require any special intervention as winter approaches. Once installed, it remains fully functional without the addition of specific equipment for wintering. The only precaution: maintain the usual water level, so that it supports the membrane in case of heavy snowfall. This principle preserves the cover from any excessive stress. A true 4-season product, Coverseal retains its elegance throughout the year and effectively protects your pool. In the spring, you enjoy preserved water: no clumps of leaves and limited photosynthesis!
Coverseal effectively limits photosynthesis, thus preserving the purity and balance of the water. By reducing the pool’s exposure to sunlight and impurities, it maintains more stable water indices, for water that is more pleasant to the touch and visually flawless. This optimal protection also allows you to reduce the use of treatment products, which are often expensive, not very ecological and irritating to the skin, while prolonging the pleasure of healthy and comfortable swimming.
To the eye, the membrane presents impeccable tension, with only a slight technical bend of about 1 cm per meter of width. This tension, combined with centrally located drain holes, prevents any water stagnation, thus limiting the accumulation of dirt. Leaves deposited on the membrane are easily swept away by the wind.
Over time, the membrane retains its perfect hold, the initial bend does not increase. In areas with extreme weather conditions, it is even more important to maintain a normal water level so that the water supports the membrane during heavy snowfall and preserves its aesthetics.
Yes, your pool stays clean once protected with a Coverseal cover. Unlike submerged or above-ground shutters, our cover does not plunge into the water: its stretched membrane acts as a barrier against external dirt. Leaves, dust or other impurities do not stagnate on the surface, they are naturally swept away by the wind, avoiding the formation of dirty puddles as is often the case with a conventional tarpaulin. Result: cleaner water, longer, with less maintenance.

- If the update freezes: If the step “Installing firmware” or “Checking cover” loops for more than two minutes, follow these steps:
-
Close the app completely.
-
Unplug the two black power cables.
-
Wait 5 seconds.
-
Plug the cables back in firmly.
-
Relaunch the app and repeat step 2.
-
The “Checking cover” phase may no longer appear, this is normal and indicates that the control board has restarted correctly.
If the update still fails or the issue persists, please contact our technical support team.
No. Each Coverseal cover is completely custom-designed, according to the specifics of your pool, your environment, and your aesthetic preferences. No predefined format: each configuration is customized in every detail, to guarantee perfect integration and optimal protection without compromise. This approach not only optimizes the safety and performance of the system, but also preserves the visual harmony of your exterior. The Coverseal adapts to your space without being imposing.
- Check the power supply :Open the side panel and make sure that the power connectors (the black cables) for both the solar panel (lower cable) and the battery (upper cable) are firmly plugged in. If the cover still cannot be found in the app, or if it does not move, proceed to the next step.
- Reinstall the mobile app : Delete the app and reinstall it. Click here for iPhone or here for Android. When opening the app for the first time, remember to allow Bluetooth access. Ensure that only one phone is connected to the cover, and log in while standing close to it. If your cover requires an update, a banner will appear directly within the app. To start the update, simply unplug and reconnect the power cables. Refer to the accompanying vidéo if needed. If the issue persists, move on to the next step.
- Test without solar power : Unplug the solar panel cable (the lower black cable). Then test the system using the wired control or the Open/Close buttons.
-
If the buzzer remains silent, the issue is most likely the fuse (go to Step 4).
-
If the buzzer sounds but the cover does not move, or moves in short bursts, the issue is probably the battery.
Whether the problem is related to the battery or a fuse, please contact our technical support team. This allows us to assist you effectively while continuing to improve the reliability and performance of your Coverseal.
-
- Replace the fuse :
- Version with 1 fuse : Disconnect both black cables, open the electronic box with a small screwdriver, and replace the fuse with the supplied 20A fuse (included in the box). Reconnect and test the cover over 1 metre using the buttons or the wired control. If everything works, reconnect via the app. If the issue persists after completing all these steps, please contact our technical support team.
- Version with 2 fuses : Open the side panel and disconnect both black power cables. First, check the battery fuse (lower position) and replace it if damaged. Reconnect and test. If the problem remains, check the motor fuse (upper position), replace it if necessary, then reconnect the cables and restart the app.
There are 2 types of rails, namely standard rails and all-surface rails. In most cases, the standard rails are installed. Their 36 mm wide by 10 mm high profile has been specially designed to remain discreet and integrate harmoniously with the pool environment. However, there is another type of rail, namely the all-terrain rail, that can be adapted to supports that lack density or flatness. In addition, the rails are never empty: the belt is always integrated, guaranteeing maximum safety and avoiding any risk of unpleasant contact.
The photovoltaic panel(s) remain efficient regardless of weather conditions. However, in countries where the brightness is particularly low or limited during the day, especially on short days in Scandinavia, it is possible to install an additional panel to guarantee perfect autonomy. At Coverseal, we are convinced that the climate must never compromise the use, safety or protection of your pool.
Coverseal is a bespoke 4-season pool cover, designed to provide optimal and long-lasting protection for your pool. Combining technology, design and ease of use, it guarantees clean and preserved water throughout the year, while enhancing your outdoor space. A high-end product that combines safety, aesthetics and everyday comfort.
The expected life of the batteries on the Automatic and Semi-Automatic models is about 4 to 6 years under normal conditions of use. However, during exceptional weather conditions (very high or very low temperatures), the service life of these batteries may be degraded. For Automatic models equipped with a winterization switch (previous version to 2025), it is important not to forget to set it to “off” from 1 September to 1 May. During this period, as there is insufficient sunlight, the batteries could then fall into deep discharge and they would have to be replaced.
Unfortunately, too many factors are taken into account to establish an accurate theoretical calculation of the insulation value of the Coverseal (delta T°, air mass trapped under the membrane, wind, rain, etc.). Therefore, it is not possible to quantify it, but the Coverseal ensures an almost perfect seal, blocking almost all evaporation. This significantly reduces heat loss, which leads to real energy savings and limits the need for water filling, for more sustainable and economical management of your pool.
Lifts are an option available on the Automatic model, the primary purpose of which is to allow the Coverseal to overcome larger obstacles effortlessly, while optimising the tightness of the cover. Lifts help preserve water quality by limiting the intrusion of impurities and conserving heat. Beyond their technical function, they also offer an elegant finish: the cover is delicately placed on the ground in a fluid and discreet gesture that demonstrates the high-end quality of your installation. Distinctive detail: an Automatic model equipped with lifts can be recognized by its square box, as opposed to a rectangular shape for the version without lifts.
Coverseal pool covers are designed with premium materials. The wear of the membrane depends mainly on climatic conditions, the maintenance provided and the daily use. It can therefore be estimated that a membrane replacement will be necessary after 10 to 12 years, depending on the environment and climate of the country where the Coverseal is installed (frost, snow, extreme heat, sand-laden wind, etc.). An essential point, however, is regular cleaning of the rails. Indeed, the presence of sand or abrasive particles in the rails can accelerate the wear of the mechanical parts and, ultimately, the membrane.
Coverseal pool covers have been manufactured in Belgium for more than 15 years and have globally recognized patents. They are commercialised by many Partners in different European countries (Belgium, Netherlands, Luxembourg, France, Spain, Italy, Switzerland, Germany, Austria, Norway,etc.) as well as in the Middle East and the United States.
When manufacturing your pool cover, the climatic conditions of the pool cover installation will be taken into account. High or low temperatures, frost or heavy snowfall are all factors that Coverseal has taken into account when designing its Product. Thus, your pool is protected throughout the year and regardless of its location.
A traditional winter cover protects your pool during the colder months, but it remains a seasonal solution, designed primarily to stop pool use. Coverseal, on the other hand, is a four-season system offering optimal protection all year round. Thanks to its membrane, perfectly tensioned across the water’s surface, it prevents leaves, dust and debris from contaminating the pool, reduces photosynthesis and helps to maintain excellent water quality. It also retains stored heat and significantly improves the safety of your swimming area.In short, while a winter tarpaulin serves a limited purpose, Coverseal combines aesthetics, performance and durability, throughout every season.
Unlike a submerged or above-ground pool shutter, the Coverseal is a true 4-season product. It provides optimal protection all year round, offering more cleanliness, safety and insulation than any shutter on the market. While a shutter floats directly on the water, inevitably letting leaves and debris fall back into the pool when it opens, the Coverseal, stretched over the edges, protects your pool from impurities. Compared to a shutter with solar blades, the difference is in the insulation: while the blades can significantly increase the temperature of the water, the Coverseal traps the accumulated heat without requiring additional protection. Finally, its design severely limits photosynthesis, thus preserving water quality and reducing the use of treatment products that are often expensive, unfriendly to the environment and irritating to the skin.
Choosing a Coverseal means offering yourself high-end protection that combines safety, performance and elegance. Its innovative design effectively protects water from dirt and temperature variations, while reducing the consumption of water, energy and cleaning products. Easy to use and perfectly integrated into your environment, it ensures optimal comfort throughout the year, for a pool that is always clean and ready to use at any time. Opting for a Coverseal also means choosing a Belgian company that places innovation at the heart of its know-how and favours the short circuit by collaborating with trusted local Partners.
Unlike a swimming pool enclosure, a Coverseal offers real comfort in everyday use. Certainly, some shelters allow you to swim underneath them, but their handling is much less practical. In addition, a shelter is often voluminous and imposes its presence, while a Coverseal, thanks to its minimalist and 100% customizable design, blends harmoniously into your environment. It also limits photosynthesis, which preserves water quality, significantly reduces the use of chemicals, and allows you to enjoy healthier water.
Practical questions
Yes, by reducing the intensity of the spray and using a neutral pH soap. Special attention should be paid to rails where regular cleaning is essential to ensure the performance and longevity of your cover. For the trim, we recommend using a microfiber cloth to preserve its appearance and durability.
The membrane that strongly limits photosynthesis and prevents leaves from falling into your pool should keep you from having to resort to shock treatments to purify your pool water. Nevertheless, under exceptional circumstances, this type of treatment may be considered. However, it is strongly recommended to keep the Coverseal open for 24 to 48 hours, to avoid any excessive concentration of chemicals that could damage the membrane.
No. Repeated shocks or excessive pressure may cause deformation of the trim or damage to the mechanics. Such damage is not covered by the warranty.
Yes, on the latest versions of the Automatic model, it is now possible to control your Coverseal from a smartphone while keeping a direct view of the cover when handling it, for safety reasons. The dedicated application also allows you to consult technical parameters such as:
– the charge level of the batteries,
– the number of opening/closing cycles performed,
– the history and details of alarms in the event of malfunction.
For previous versions, an upgrade is possible in order to activate the opening and closing control via your smartphone. We recommend that you contact your Partner directly for more information.
It is not necessary to walk on it to clean the membrane: a low-pressure cleaner (set to moderate power) or a telescopic handle is more than enough. However, you can walk on top of them barefoot or with flat-soled shoes, without any risk. A quick reminder: the Coverseal provides effective protection in the event of an accidental fall, but it is not designed to be used as a playground.
Our covers do not require any special technical maintenance. However, it is strongly recommended to carry out regular cleaning of the rails and mechanism to remove any accumulation of sand, soil, leaves, branches or other dirt that may affect proper functioning and life of the cover. In addition, it is necessary to respect the rules stated in the user manual, such as maintaining the appropriate water level in your pool, in order to preserve the safety of the cover.
Regardless of the model, your pool cover can always be opened or closed manually. Even in the event of a battery failure, there is always a solution! However, the manual manoeuvre should only be used in the event of a power failure and should not be used to loosen your cover.
1. Remove the 2 flaps (one on each side of the trim). For modules without cylinders, go directly to point 3.
2. Lift the trim on each side until you hear the click.
3. Identify the red motor cable and disconnect it.
4. Identify the manual manoeuvring flange and insert the extension provided during installation.
5. Place the racagnac (ratchet wrench) at the end of the extension, and adjust the knob to the desired position.
You can now operate the system to open or close the cover. To put your cover back in place, reverse the steps from 5 to 1. To lower the trim (only on models equipped with cylinders), actuate the two levers inside it by lifting it slightly before lowering it again.

On previous generations of Automatic models, the winterization switch allowed you to disable the remote control receiver to preserve the batteries during the low season, when the sunshine is lower. It is recommended to place it in the OFF position from 1 September to 1 May. Otherwise, the batteries could fall into deep discharge and require replacement. Note: on the latest versions of this model, this switch is no longer present, because energy management has been optimized.
All you need to do is:
– close the cover completely
– maintain the water level of your pool according to the instructions in the user manual;
– clear the solar panel(s) of the Automatic model in case of heavy snowfall to maintain a good charge of the batteries
– set the winterization switch to off in order to preserve the batteries (previous versions of the Automatic model)
Thanks to the membrane, photosynthesis is strongly limited: no noticeable dirt is found in the spring. For optimal results, it is advisable to run the filtration only a few hours a day during wintering.
