For stamped concrete, there are 2 different ways to apply the base color of the concrete. One way is to mix the color directly into the concrete, ie at the plant or in the truck on site. This technique is referred to as “Integral Color” or “Integral Pigment”, or “Through-and-Through color”.
The other technique is where a special powder color pigment is applied and absorbed into the surface of the concrete when the concrete is first placed (still wet). This technique is referred to as “Surface Color Hardener”, also called “Shake-On color”, “Toss-On color”, or “Broadcast color”.
NOTE: Traditional stamped concrete always has 2 colors, a base color and a “marbled in” highlight color. This discussion is only about the base color. The highlight color is most always applied as a powder just before the concrete is stamped. So again, this discussion of integral vs. Surface Color refers only to the application of the base color.
Both Integral Color and Surface Color Hardener are acceptable coloring solutions. They’re both strong, durable, and long-lasting. They both have the same maintenance. They both come with the 2-tone color, ie base color and highlight color application.
NOTE: Integral Color can be mixed into the concrete either at the plant or onsite directly into the truck. Most would argue that having the color mixed at the plant is the better approach for an Integrally Colored concrete project. Ready-Mix concrete companies have “million dollar” process, research, and modern equipment to measure and weigh the coloring chemicals to produce the most accurate color. However, some contractors prefer to mix the color onsite directly into the truck. With this process, the contractor will bring their own color in a bucket or other container to the jobsite and when the concrete mixer / truck arrives, the contractor will climb up onto the back of the truck and dump the color into the drum to mix the color into the concrete. Adding the color this way requires more skill by the contractor to understand the timing and mixing chemistry to achieve a similar accurate mixture as would be achieved by having the color done at the concrete plant. Mixing the color onsite by the contractor, for many contractors is more convenient and those feel as though they have more control over the situation and get the color mixture that they want.
As you research this topic of coloring techniques, be sure you have a good understanding of both techniques. On the surface (no pun intended …. ) most customers inherently and immediately want the Integral Color, the one that’s mixed through and through … everyone says the same thing:
What if I get a chip?
Most all customers perceive Integral Color to solve this problem. If a chip occurs, since the concrete is colored through and through, I’m “good to go”. The fact is, that concrete on the inside looks nothing like the decorative stamped surface on the outside. So yes, you will see the color, but you will also see stone, sand, fine aggregates, etc. The fact is, concrete is pretty ugly on the inside, and you may want a repair anyway.
Most all customers perceive the other coloring technique, Surface Color Hardener to be “cheap” or “chinsie” as to say we’re trying to “pull a fast one” on them … Customers always ask about surface color:
What happens when I wear through it?
What happens when it chips off?
Do I have to reapply it when it fades away?
If I get a chip, I don’t want to see the white bare concrete underneath.
……….. therefore, I think I want the through-and-through color ……….
Most customers don’t want the Surface Color Hardener, we believe, because they simply don’t understand what it is. Most think it’s some sort of spray, or stain, or paint. Most customers think we are trying to cheat them out of something by mentioning or recommending the Surface Color Hardener. The fact is that many experts in the business believe that Surface Color Hardener is the better approach, ie pros far outweigh cons … see lists below.
But again, the decision is yours. We have experience with both and we are happy to apply your color either way. Let’s talk about this more when we meet. Here is a run-down of some pros and cons of both techniques:
NOTE: For this list below, we do our best to leave out our opinions and emotion, and simply state these pros and cons as factually as possible.
