Some prep work is required to achieve good adhesion, and you can use the Aqua Mix Grout Colorant Pre-Treatment Cleaner to prepare your tiles for application. Each grout colorant kit comes with everything you need to change grout color or clean grout, including the pre-treatment as well as a small brush. For the best results, do your best to keep the colorant in the grout lines, covering the existing grout with the new "paint-on" color. If colorant gets on adjacent tiles, don't worry, just wipe it off with a dampened cloth or use a white scrub pad and water to remove colorant from the tiles. Always follow instructions included with the kit and reference the Aqua Mix grout colorant chart for a successful application.
Fully cured grout colorant is permanent and will withstand routine use in your home's bathroom or kitchen when it's applied correctly and cared for with routine cleaners. Never use a solvent-based cleaner on recolored grout joints. Previously applied sealants will need to be removed before colorant can be applied or it will not bond well. There are limitations and some special instructions for specific types of tile, so make sure to read the full label and instructions prior to use. Some porous stone tiles may need to be sealed before grout joints can be colored. As always, we recommend that you test for compatibility before full application. Questions?
