NOTE: A bonding agent may cause the concrete color to be slightly lighter in shade than you originally planned for. Apply Concrete Mixture It’s no coincidence that both the colour of most standard mortars and cement is a grey’ish colour. This is due to the fact that the grey colour-tones of the cement go a fair way into the overall colour of the mortar.
They are available in a huge range of different shades and colours and can be used to change the colour of a mortar mix to match any given existing mortar or surface.From concrete plastisicers and mortar water proofers to cement accelerators, retarders, dyes and everything in between, we’ve got it at Selco.
Concrete can also be stained after it has been poured. And you can always paint concrete to give it virtually any look you want. Can cement all be colored?This method requires that the concrete has been poured and finished, but should still be "wet." Sprinkle on the Powder Matching mortar colours is often required with older, period properties where repairs that are carried out need to be made invisible.
Now that we have established the probable types of sand and cement or lime that was used for the original mortar mix, all that remains is to match the correct cement content.

Concrete and All Other (General) Uses ASTM C 150 for portland cement is the most common cement spec in North America. Of the five basic types of cement covered under this spec, Types I through V, Types I and III white cement are the most prevalent, but Types II and V are also manufactured. Manufacturers usually control color of white cement by limiting the amount of iron and manganese oxides allowed. why is it used in decorative concrete. If concrete is going to be stained, it's better for the concrete to be completely dry and cured before the stain is applied. Ideally, you'll wait about a month before adding stain to new concrete.Ask if you can have a small sample of each so that you can run some colour matching experiments (more on this later). Its boring and time consuming, but if you do not want your repairs to stand out a mile off, it has to be done!
This may take a day or so but you will need to be patient as each one needs to be fully dried to get an exact colour. In some cases it is possible to take a sample of the original mortar, break it down and separate out the sand. With a sample of the original sand to hand you can then use it to compare against sand from different sources until you find an exact or very close match. Step 1 – Get Samples Once dried, simply hold your sample board up to the existing mortar and look along the line until you spot a close or identical colour match and this will indicate the mix ratio to go for. For a more vibrant look, apply the remaining 2/3 pound of pigment to the concrete and repeat the entire process.Place the sand on an old sheet/cloth and leave it somewhere out of the way to fully dry off. Once dry, pop it into a clear sealed jar or container. Step 7 – Match the Sample This is easy enough to do but does involve a little time and patience as you will need to create a range of different mixes using different ratios of cement to sand.
