How do I add color to grout?
PigmentStart with white grout powder so you can add color. Choose your color pigment from a home improvement store. Determine the amount of pigment needed for the area of tile you will lay. Measure the color pigment needed for your tile area, and add it to your white grout powder.MixingAdd just enough water to your dry grout powder and colored pigment to form a mixture that is the consistency of cake batter. Stick a putty knife into the grout. The grout should stick to the knife and look smooth without any lumps.TimingMix only enough grout that you can apply in a half hour. After a half hour the grout will start to harden and loose its spreading properties. Keep extra grout powder and colored pigment on hand if you accidentally add too much water on your first mixing.
