The sparkling tiles of your swimming pool are the star of the show, but the grout you choose is the unsung hero that holds it all together. The right grout not only enhances the beauty of your tiles but also protects your investment from the harsh realities of pool chemicals, constant water exposure, and UV rays. At AquaBlu Mosaics, we understand that selecting the perfect grout can be a daunting task. This guide will walk you through everything you need to know to make an informed decision, featuring some of our top-rated grout products. 

The Great Grout Debate: Epoxy vs. Cementitious

The first and most crucial decision you'll make is the type of grout to use. For swimming pools, the choice primarily comes down to two options: epoxy and cementitious grout. 

Epoxy Grout: The Durable Defender

Epoxy grout is a combination of resins and a hardener, creating a durable, waterproof, and stain-resistant finish. It's the top choice for swimming pools for several reasons: 

  • Superior Durability: Epoxy grout is incredibly strong and resistant to cracking, shrinking, and wear. It can withstand the constant pressure and movement that a swimming pool endures. 
  • Waterproof and Chemical-Resistant: Unlike its cementitious counterpart, epoxy grout is non-porous, meaning it won't absorb water or be broken down by pool chemicals. This prevents the growth of mold and mildew, keeping your pool looking pristine. 
  • Vibrant, Long-Lasting Color: Epoxy grout colors are fade-resistant, so they will maintain their brilliance even with constant exposure to sunlight and chlorine.

For a top-of-the-line epoxy grout, we recommend the Starlike EVO Epoxy Grout series. Available in a stunning array of colors like the deep and enchanting Zaffiro C-260 (Sapphire Blue) and the serene Verde Salvia EVO 400 (Sage Green), this grout is a two-component, acid-resistant formula that is both beautiful and easy to maintain. 

Cementitious Grout: The Traditional Choice

Cementitious grout is a mixture of cement, sand, and water. While it has been the traditional choice for years, it has some drawbacks for pool applications. However, modern advancements have led to high-performance cementitious grouts that are suitable for pools. 

  • Cost-Effective: Cementitious grout is generally less expensive than epoxy grout, making it a budget-friendly option. 
  • Easy to Work With: It has a longer setting time than epoxy, making it more forgiving for DIY installations.

If you opt for cementitious grout, it is crucial to choose a high-quality, polymer-modified product designed for submerged applications. We recommend the Stylegrout Tech line, which is a flexible, water-repellent, and anti-efflorescence cementitious grout. It comes in a variety of colors, including a sleek Black and a warm Brown, and is formulated to resist fading and staining. 

Specialty Grouts for a Touch of Luxury

For those with glass tile or looking to add a unique flair to their pool, there are specialty grouts and additives that can elevate your design. 

For the Love of Glass Tiles: Translucent Grout

Glass tiles require a special kind of grout that won't detract from their beauty. The Starlike Crystal Glass Grout is a translucent epoxy grout that is a game-changer for glass mosaics. Its unique formula allows it to take on the color of the surrounding tiles, creating a "chameleon effect" that enhances the tile's natural beauty without the distraction of traditional grout lines.

Add a Little Sparkle: Grout Color Packs

Why settle for a plain grout color when you can have a shimmering, jewel-toned finish? With our grout color packs, you can add a touch of sparkle and personality to your pool. The Gold Color Pack and the Black Pearl Color Pack can be mixed with the Starlike EVO Epoxy Grout to create a stunning, glittery effect that will make your pool truly one-of-a-kind. 

Making the Right Choice for Your Pool

Choosing the right grout is a critical step in creating a beautiful and long-lasting swimming pool. Consider your tile type, budget, and desired aesthetic when making your decision. For the ultimate in durability and low maintenance, epoxy grout is the clear winner. However, high-quality cementitious grout can still be a viable and cost-effective option.  No matter which type of grout you choose, proper installation is key. Always follow the manufacturer's instructions and consider hiring a professional for the best results.  Ready to find the perfect grout for your pool?
