Grout problems can ruin the look of beautiful tile work, leaving you with stained, cracked, or discolored lines that make your entire installation look old and worn. Traditional grout requires mixing, careful application, and constant maintenance to keep it looking its best, but even then, it can absorb stains and break down over time.
LATICRETE SPECTRALOCK® 1 is the answer to all your grout headaches. This pre-mixed, ready-to-use professional-grade grout comes in a stunning bright white color and delivers lifetime protection against stains and color loss. Unlike ordinary grout that absorbs liquids and discolors easily, SPECTRALOCK 1 locks in its color while blocking out stains, keeping your tile installations looking freshly done for years to come.
What sets this grout apart is its incredible strength. Testing shows it has a PSI rating 10 times higher than standard pre-mixed grouts, making it the strongest one-step grout available. This means it resists cracking and can handle heavier foot traffic, perfect for busy kitchens, bathrooms, entryways, and commercial spaces. Plus, it meets the strict ANSI A118.3 standards for professional installations that need to last.
Available in all 40 LATICRETE grout colors and 12 SPECTRALOCK DAZZLE additive options, this grout lets you create everything from classic looks to dazzling glitter effects or even glow-in-the-dark designs. The uniform color consistency ensures professional results every time, whether you're working on a small bathroom backsplash or a large commercial installation.
Because it's pre-mixed and ready to use, there's no messy mixing or guesswork involved. Just open the container and apply it like a professional. The specially formulated SPECTRALOCK sand ensures uniform color consistency, so you get the same beautiful result every single time. It's professionally engineered to maintain its appearance year after year, so you never have to worry about regrouting or touch-ups.
Whether you're a professional contractor looking for the best materials or a DIY enthusiast wanting professional-quality results, LATICRETE SPECTRALOCK® 1 delivers the performance and reliability you need to create beautiful, long-lasting tile installations that stay looking perfect for a lifetime.
