Two-part epoxies are the preferred choice of professional contractors to address the wear and tear of swimming pools caused by continuous exposure to water, chemicals and the elements. These durable coatings form a protective barrier that enhances the longevity of the pool surface. Unlike quick fix DIY pool patches, two component epoxy systems provide exceptional strength, chemical resistance, moisture resistance, durability, versatility and reliability for repairs around the pool.  In this article, we will explore

    • the advantages of using two-part epoxies for professional pool repair, from their remarkable durability to chemical resistance, and
    • how two-part epoxies are used to repair swimming pools.

Advantages of Two-Part Pool Repair Epoxies

Two-part epoxies typically consist of a resin and a hardener that need to be mixed together before use. When these components are mixed, a chemical reaction occurs, leading to the curing or hardening of the epoxy, resulting in a strong and durable material. Two component epoxy systems are thermosetting polymers meaning once reacted and crosslinked the process is irreversible. Once cured and crosslinked these polymers exhibit excellent moisture and chemical resistance.

Two-part epoxies are perfect for professional pool repair due to these advantages:

    • Excellent Bond Strength: Two component epoxy systems provide a true structural material. These materials create a robust bond that can withstand significant stress and load. They can be applied to a wide range of materials including PVC, metal, fiberglass, ceramic, vinyl, concrete and wood.
    • Versatility: Two-part epoxies are versatile and can be used for bonding, sealing, filling, and even structural repairs. Because these are 100% reactive systems there is no solvent to flash off, no VOCs allowing for repair application in a single pass. For pool repair, they can be used to repair light rings, skimmers, main drains and most other fixtures, both above ground and underwater. You can also use them to securely bond PVC fittings to copper, galvanized or existing pipes, or as a patching compound for cracked concrete, pavers and brick constructions.

    • Durability: Once cured, two-part epoxies are highly resistant to chemicals, heat, moisture, and UV exposure. This durability makes them suitable for both indoor, outdoor, above water and underwater pool repair.
    • Curing Time: Two component epoxy based systems allow for ample working time while still providing a full cure after 24 hours at room temperature.
    • Color Options: Many two-part epoxy formulations can be tinted or colored, allowing for customization of the final appearance. This is particularly useful when aesthetics is a consideration. For example, AquaBond UW-5200 which mixes, applies and cures underwater brings all the performance and properties of AquaBond UW-5000 into an “easier to hide” in the pool environment grey color.

Using Two-Part Epoxies to Repair Swimming Pools

Using two-part epoxies for pool repair involves careful surface preparation, mixing the two components, and applying the epoxy to the surface, crack or leak.

Mixing the epoxy can be tricky. You need to understand the mixing ratios and any specific requirements for the product you’re using, then thoroughly mix the two components together until they are homogenous, ensuring there are no streaks or inconsistencies in the mixture. At the same time, you need to pay attention to the epoxy’s “pot life,” which is the working time you have before it starts to harden. It’s important to apply the epoxy within the specified pot life to ensure proper curing.

Fortunately, there is a better way – using a dispensing gun and static mixers. The AquaBond System is a great example. With the AquaBond System, you mix and apply only what you need, only when you need it. Here’s why this method is better:

    • Static mixers ensure a precise and consistent ratio of the two epoxy components. This is crucial for achieving the desired properties of the epoxy, such as bond strength, curing time, and durability.
    • Static mixers are designed to thoroughly combine the two epoxy components as they pass through the mixer’s mixing elements. This results in a homogeneous mixture, without streaks or inconsistencies.
    • The mixing action of a static mixer minimizes the chances of air being entrapped in the epoxy mixture. This is crucial because air bubbles in the epoxy can weaken the bond and reduce its overall effectiveness.

There are more advantages. Using static mixers can significantly reduce the time required for mixing two-part epoxies compared to manual mixing, as well as cleanup time. Contact with resins is eliminated. Used mixers and epoxy cartridges can go into regular trash, without the need for hazardous waste handling.

In conclusion, two-part epoxies are a versatile and reliable choice for professional pool repair. Their exceptional bonding strength, durability, and versatility make them ideal for addressing leaks and cracks in swimming pools. When used in conjunction with static mixers and a dispensing gun, the epoxy application becomes even more precise and efficient. The static mixers ensure a consistent and thorough blending of the epoxy components, leading to a homogeneous mixture that guarantees the integrity of the repair. Furthermore, the dispensing gun allows for accurate and controlled application, reducing waste and ensuring that the epoxy is distributed precisely where it’s needed. The combination of two-part epoxies, static mixers, and a dispensing gun streamlines the pool repair process, making it a preferred choice for professionals seeking high-quality, long-lasting results.
