Color of the concrete surface, might differ slightly from the color chart presented;
Sometimes we can come across errors in materials (we can’t cover all the costs);
Vegetation, acts of God, weather can’t be controlled by the contractor;
If you decide that you want to request a seal service for your bare concrete(grey, plain that been recently poured or just protect an old one), know: because every slab is unique in its color and texture, the color of the concrete after sealer application is difficult to predict. The mix design, temperature, humidity, use of chemical admixtures, finishing techniques and porosity are just a few factors that will affect the concrete surface color. A sealer will deepen the true color of concrete and will highlight all the differences in the surface texture that result from floating and finishing. If you are looking for a esthetic look I would suggest to apply a solid coat, in this way you wouldn’t see imperfections. If you decide to do it, please Contact Us 239-233-1321;
Concrete sealers have limitations and require some level of maintenance to keep them looking and performing at a high level. Life span will vary by the type and traffic the sealer is subject to;
Resealing will not fix issues with the concrete, such as color failure or efflorescence.
Concrete is made up of multiple materials. The stone, sand, water and cement are used to make concrete. These ingredients are nonidentical from location to location.
If one were to add an exact amount of the same pigment to 2-3 batches of concrete produced on different sites, the final colors would almost certainly not match. Not only would they not be an exact replica, but depending upon how different the color of the raw concrete is, the colored loads could vary by several shades!
There are simply too many variables that affect concrete’s final color.
A few of them are listed below:
Weather and site conditions
Relative humidity, dampness of the substrate, sun or shade, and windy conditions can all influence finishing practices and the final tone.
Moisture on the surface
Both during and soon after finishing, additional moisture on the surface, followed by evaporation, will cause the color to become a lighter shade.
Sealants have a huge effect on final tone. Solvent-based acrylic sealers generally provide a higher gloss and can dramatically darken colors. Water-based, on the other hand, generally look more natural, less glossy and don’t darken the concrete as much. Penetrating sealers typically don’t change the appearance of concrete at all. The sealed surface appears virtually the same as unsealed colored concrete.
Considering these factors and more, it’s impossible for anyone — whether he or she is a manufacturer, concrete producer or contractor — to guarantee that the concrete’s final color will duplicate the color chart and everything will be perfect.
