Grout secures tiles to a number of hard surface, ranging from entire kitchen floors to smaller mosaic art projects. It's a versatile material that's easy to work with. Despite its usefulness, though, grout clashes with many interior designs. Your grout colour choices are often limited at the hardware store to whites and pallid greys. Fortunately, you can dye white grout with a number of colourants. If you apply colourants properly during the grout mixing process, your grout aesthetic options are limitless.
Pour the grout powder into a bucket or bowl.
Add dry colourants to the bowl as desired. Grout can be dyed with a wide variety of substances, ranging from coloured powders to liquids. Herbs, glitter, spices and other powdery, brightly-coloured items are useful for dying grout, according to "Mosaics in an Afternoon." Add powdery colourants until the white powder turns the desired colour, or skip this step if you are using a liquid colourant.
Measure water for your grout mixture. Depending on the brand of grout you're using and how thick you want your grout, the water content varies. Consult the grout powder's packaging for the manufacturer's recommendation.
Mix liquid colourants directly into the water. Acrylic paint and food colouring work well as liquid colourants. If you used a dry colourant, skip this step.
Pour the water into the mixing bowl.
Mix the water and powder together with a stir stick, or use an electric drill mixing paddle for larger jobs. Once mixed together, the grout is dyed and ready to use.
