This is one of … It has no binder, so it must be mixed in with the concrete to "lock in" and bond. The proper product for surface application is a We built a veterans' memorial last year and used a color additive in the concrete. This Here's the bottom line: The location of the sidewalk, the water migration, and the makeup of the concrete are all converging in a perfect storm to cause these problems. On closer inspection, you can see small rocks in the middle of some of these pits, while other pits have nothing in them but are very unsightly. Are the discoloration and pitting problems caused by the sprinklers, or is there something more to it? If you want to darken the concrete color or give it a glossy appearance, apply a low-solids acrylic sealer as a final coat. The sidewalk is tinted a Santa Fe color and is 4 inches thick, with a brushed finish.

If it's applied to the surface, there is no way to get a strong bond between the color and the concrete. How do I remove the sealer and wash off the release to reduce the intensity of the secondary color?When concrete is stamped using colored antiquing release, the stamps actually push some of the colored powder into surface of the concrete. Since a non-reactive stain colors the concrete by filling the concrete’s pores or by creating a film that sits on the concrete’s surface, typical moisture-related problems include … Available at most concrete distributors, these surface evaporative control chemicals are a must for anyone placing any type of decorative concrete.

When color is added to any cement based mix, the smaller pigment particles cover the larger cement particle.

When placing large areas of colored concrete over days, weeks or months, take into consideration the ability to maintain color consistency.Consider breaking up the large areas with bands of different color and or texture. The depth and type of texture on the imprinting tool will determine the amount of secondary color to use. While the technology has changed little in the last 50 years, its uses and popularity continue to grow. By adding this colored powder to traditional gray concrete, it became possible to achieve a wide range of earth tone colors. Integral color should never be used as a surface-applied colorant.

A less-expensive option is to apply a special waterproofing sealer to the concrete. To learn about the differences, see Last week, we poured a band of integrally colored black concrete.

Those natural colors will make the color look faded. The problems noted with the concrete, and the photo showing joint deterioration, have little to do with the lack of surface curing.

The addition of water permanently changes the concrete, typically lightening the final color.

First, a good cleaning will be needed to prepare the concrete to take the sealer. Contact us and view our privacy policy, terms & conditions, and press room for the entire job.

The "discoloration" is actually the base color that should have been visible in the first place, but was covered with too much secondary color.The repair is fairly simple in theory, but more difficult in practice. Test this in an inconspicuous area first to be sure you are getting the results you and the homeowners desire.We applied concrete dyes to the floors in several rooms of this house, but the dyes failed and we are seeing a white powdery residue. I was told by the contractor that it would take awhile to cure and to expect it to do all sorts of "weird stuff" while it was curing. As a result, the sealer lifts up in small circular areas and takes the secondary color with it, since the color is all it had to hold onto. To help avoid this potential problem, the use of a matching colored curing compound or colorwax is always recommended when pouring colored concrete.In fact some manufacturers color cards and colored samples are based on a finish with a colored curing compound. Magnifying the problem is the fact that the concrete sits at the bottom of the hill, where the water concentrates. Depending on type of tinted sealer, typical material cost per square foot runs $0.07 to $0.25.Another proven method for changing color is the use of water-based stains. Courtesy of Lanxes Corp.Adding additional water during brooming creates inconsistent color streaks.Becoming proficient at the basics before moving on to more difficult tasks is important in most everything, especially when it comes to decorative concrete. Are the areas where the white residue is occurring near walls or exterior landscaping that is wet or holds water, such as lots of dirt built up alongside the outside wall?

The sealer has to be chemically stripped, but the process will usually remove most of the secondary color as well. Consider that the color you add to the mix has to overpower the gray base color of the concrete.
Concrete discoloration comes in the form of dark spots, stripes, blotchy areas, and color differences. Instead, use a surface evaporative control agent.
Once again, add color to concrete and you can expect the people writing the check to scrutinize the final product from the day it is poured and for years to come. This is not an issue that we have dealt with before, so I am a little concerned. These highlights make the concrete look like stone, tile or whatever natural material the installer is trying to mimic. The ready-mix supplier claims to have put color in the mix, but the finisher claims to not have seen any color when placing the load. What are my options?

Cracking. First, we need to use the right terms. There are many different products and methods for imparting secondary color, depending on the final look desired and the applicator's preference. This usually requires stripping back down to bare concrete, applying a waterproofing sealer or membrane, and then coming back with a topping that can be dyed or sealed. The most important step with this project is to seal the concrete once the surface is clean and dry. Unfortunately, complaints about how color turns out are an all-too-familiar topic of conversation.
