Read on to find out why AquaBond’s permanent waterproof gap and seam filler is a better alternative to traditional waterproof silicone sealants.

Disadvantages of Waterproof Silicone Sealants for Pool Repair

When it comes to sealing gaps and seams in swimming pools, pool contractors have often used silicone sealants due to their water resistance and flexibility. These adhesive sealants are hydrophobic (resist water), flexible, and readily available. However, waterproof silicone caulk and sealants have many disadvantages when it comes to pool repair applications.

  1. Limited Adhesion: The subpar adhesion of silicones, combined with their elastic nature, make silicones very easy to peel up from a substrate.
  2. Preparation Requirements:Proper surface preparation is crucial for silicone sealants to adhere effectively. This may involve cleaning, drying, and possibly priming the substrate before application. Failure to adequately prepare the surface can compromise the sealant’s performance.
  3. Curing Time: Silicone sealants typically have a longer curing time compared to other types of sealants. In pool repair scenarios where rapid sealing is necessary to prevent water loss or damage, the extended curing time may be a drawback.
  4. Susceptibility to Pool Chemicals: While silicone sealants exhibit good resistance to water, they may be susceptible to degradation or discoloration when exposed to common pool chemicals over time. This can affect the longevity and appearance of the repair.
  5. Limited Strength: While silicone sealants are suitable for sealing joints and small cracks, they may not provide sufficient structural support for larger repairs or areas with significant movement.
  6. Incompatibility with other materials: Silicones are excellent mold release agents. Once silicone is applied to a surface, it is very difficult to remove it completely, therefore degrading the performance and aesthetics of other grouts, adhesives, and paints.

AquaBond Permanent Waterproof Gap and Seam Filler is Better Than Waterproof Silicone Sealants for Pool Repair Applications

The AquaBond ABC-9100-300 Waterproof Permanent Seam and Gap Filler is designed with the needs of professional pool contractors in mind. Here’s why they are superior to traditional waterproof silicone sealants:

  • Adhesion: AquaBond ABC-9100-300 was custom-formulated for the pool and spa market with additional adhesion promoters for common substrates such as glass, ceramic, PVC, ABS, nylon, and stainless steel.
  • Preparation Requirements: Although it is always best to prepare and clean a surface to be bonded, AquaBond ABC-9100-300 is formulated with a surfactant package to bond through those less-than-perfect substrates.
  • Permanent Flexibility: AquaBond ABC-9100-300 is formulated with a permanent flexibility that allows them to move with the pool’s substrate, preventing cracking and separation over time. This flexibility ensures that repairs withstand the natural movement of the pool structure over time, providing peace of mind for contractors and pool owners alike.
  • Strength: Aquabond ABC-9100-300 easily outperforms silicones in tensile strength and adhesion.
  • Non-Sag: AquaBond ABC-9100-300 features rheology, meaning it will maintain its shape and consistency even when applied to vertical surfaces or overhead while still only requiring the dispense force of a flowable product. This property makes it ideal for filling gaps and seams in any part of the pool, including walls, floors, and joints, without dripping or running.
  • Wide Temperature Range: AquaBond ABC-9100-300 can be applied at temperatures as low as 32 degrees Fahrenheit, making it suitable for use in various climate conditions. Pool contractors can confidently undertake repair projects year-round, regardless of weather conditions.
  • Chemical Resistance: AquaBond Waterproof Permanent Seam and Gap Filler boasts excellent chemical resistance, ensuring it will maintain its integrity when exposed to pool chemicals and other harsh substances. This resistance enhances the longevity of repairs, providing added value to contractors and pool owners alike.
  • UV Inhibitors: For above-water applications, AquaBond Waterproof Permanent Seam and Gap Filler is formulated for UV resistance, not only to form the backbone of the material but also with the addition of UV inhibitors that protect against sun damage and degradation. This feature extends the lifespan of repairs exposed to sunlight, maintaining their appearance and performance over time.
  • Quick Skinning Time: AquaBond Waterproof Permanent Seam and Gap Filler skins over in under 5 minutes, allowing for efficient application and faster project completion.
  • Compatibility with other materials: Unlike silicone-based sealants, Aquabond ABC-9100-300 leaves no residue.
  • Can be Painted Over: Additionally, they can be painted in just 24 hours, minimizing downtime and inconvenience for pool owners.
  • Convenient Packaging: Packaged in a standard caulking-gun-sized tube, AquaBond ABC-9100-300 is easy to handle and dispense. While the AquaBond DM-250 High Thrust Dispensing Gun is recommended for optimal results, you can dispense ABC-9100-300 using any heavy-duty caulking gun.

How long does silicone waterproofing last?

A silicone sealant can last 10 to 20 years, depending on the quality of the sealant and whether the caulking is exposed to the sun, chemicals, and other elements. AquaBond’s professional-grade Waterproof Permanent Seam and Gap Filler offers a more durable waterproof sealant than most common silicone sealants and is best suited for water environments like swimming pools and spas.

How long does waterproof silicone sealant take to dry?

Silicone sealants can dry to the touch in 30 minutes to an hour, but they are only waterproof after they cure completely, which can take anywhere from a few hours to days. AquaBond’s professional-grade Waterproof Permanent Seam and Gap Filler skins over in 5 minutes and can be painted over in 24 hours. This makes it a convenient and time-saving alternative to traditional waterproof silicone sealants.
