Frequently asked questions
1. What’s the difference between a grout colorant and a regular cleaner or sealer?
A grout colorant not only refreshes the color of dull or stained grout but also acts as a protective sealer that prevents future staining. Unlike standard cleaners that remove surface dirt, colorants penetrate the grout and create a durable coating that restores uniform colour and extends surface life.
2. Can I apply grout colorant over existing sealed grout lines?
Yes, but only after proper preparation. The surface must be thoroughly cleaned and free from existing sealers, residue, or oils to ensure proper adhesion. We recommend using a grout pre-cleaner or neutralizing solution before applying the colorant for long-lasting results.
3. How long does grout colorant last, and is it durable in high-traffic areas?
Our professional-grade colorants are engineered for maximum durability, typically lasting 5–10 years depending on foot traffic and maintenance. Once cured, they resist moisture, mould, and daily wear, making them ideal for commercial, industrial, and residential settings alike.
4. Can I match or customize the grout color to existing tiles?
Absolutely. We offer a variety of color options designed to complement popular tile tones. If you’re managing a large-scale or custom project, our team can recommend shades that best match your client’s existing surfaces for a seamless finish.
5. How easy is it to apply the grout colorant? Do I need special tools or training?
The application is straightforward and does not require specialized training. Using a small brush or applicator bottle, simply apply the colorant evenly along grout lines, allow it to set, then wipe away any excess from tile surfaces. For professionals handling multiple projects, ASE also provides training and demonstrations on product use for faster, more efficient application.
