Mortar, a masonry product consisting of sand and cement, is a binding element used to hold bricks and other similar building materials together. Combining mortar colours can make mortar more aesthetically pleasing and give the surface a fresh, new look. Mixing mortar colours yourself may sound intimidating, but with a little planning and the proper tools, the task should go smoothly. Follow these steps to learn how to mix mortar colours.

Things you need

Remove one-quarter inch of the current mortar using a hammer and chisel, if applying new mortar to a premortared surface. Be sure to aim the chisel carefully when striking it with the hammer so you don't damage the surrounding brick.
Pick out a final pigment colour for your mortar. Use a colour chart, often available on the pigment powder packaging, or ask a home store representative for guidance when choosing the pigment colours to combine to create your final mortar colour.
Mix fresh mortar in a large bucket, according to the manufacturer's instructions. Pour in a powdered pigment. Follow the manufacturer's instructions to ensure the proper ratio of pigment to mortar. Pour in a different-coloured powder pigment in an equal ratio to the first pigment to combine the two pigment colours. Mix the mortar thoroughly to evenly mix the colours.
Scoop out a small sample of mortar with a trowel. Scrape part of the sample onto a mortar board to ensure that you have achieved the desired colour. If not fully satisfied with the colour, add more pigment and combine it with the mortar as needed.
Scoop out the mortar with a trowel and apply it to the spaces, or gaps between the bricks, once the mortar colours are properly mixed. Use the trowel to scrape off any extra mortar. Allow the coloured mortar to dry fully.
