Concrete goes from a dull, rough surface to a shiny, smooth, polished surface through a series of grinding steps. This grinding is done with a series of diamond impregnated floor pads. These pads contain millions of microscopic diamonds that are used to grind the concrete and make it smoother.
How do you clean concrete to make it look new?
Steps to recolor faded stamped concrete:
Apply additional coats of stain without waiting for the first coat to dry. Allow the final coat of antiquing stain to dry for at least 8 hours. Once the stain has fully dried, apply a solvent-based acrylic concrete sealer to protect the color from fading in the future.

Once you have a fairly smooth concrete surface, and after the concrete is dry, you can employ either chemical or mechanical polishing techniques to get the desired glossy, smooth finish.
How do you make fresh concrete white?
Some contractors use one or more muriatic acid washes to artificially weather concrete. Others suggest first etching the surface, then washing it with a mixture of carbon black and water. A third alternate is using a diluted black or brown concrete stain to darken the color.

Concrete defects are cracks, chips, spalls, holes, and other imperfections that can appear in the concrete. These defects can occur during the mixing, placement, or curing process and after construction.
What makes concrete look wet?
However, calcium chloride and (to a lesser extent) sodium chloride have been shown to leach calcium hydroxide and cause chemical changes in Portland cement, leading to loss of strength, as well as attacking the steel reinforcement present in most concrete.
What brightens concrete?
Bleach is commonly used to whiten concrete and is very effective at doing so if the initial stain is removed beforehand. Bleaching stained concrete white prepares it for any additional coloring treatments that you may wish to apply in the future.

White vinegar and a little scrubbing with a brush is a very effective, eco-friendly way to remove rust stains from concrete—even those that are decades old. Pour the white vinegar directly onto the stain, allow the liquid to penetrate the area for 20 minutes, and scrub with a stiff-bristled brush.
Can you darken new concrete?
No single factor is responsible for all discoloration. The discoloration factors are calcium chloride mixtures, cement alkalis, hard surfaces, inadequate or insufficient curing, wet subsurface, varying proportions of aqueous cement on the surface, and changes in the concrete mixture.
How do you darken old concrete?
A frequent reason behind a darkened-concrete appearance is the addition of calcium chloride to accelerate the setting time of concrete (see Photo 1), especially when calcium chloride dosages approach 2% by weight of cement.
What does bad concrete look like?
Blackening of the surface is common when the concrete is “burned by late and vigorous troweling”. The more the troweling effort, the more compacted and dense the concrete surface becomes. The result is a reduction in the moisture content (water cement ratio) at the surface.
What is the best repair for concrete?
Some contractors use at least a little degreaser for most jobs, even to remove dirt, which can be somewhat oily. According to Hinckley, alkaline cleaners are also the preferred chemical for cleaning soot from concrete.

Let it sit for a while, then mop the patio and rinse it with fresh water. Repeat the process as many times as needed.
Will bleach turn concrete white?
You may think that power washing concrete surfaces can't possibly cause any damage because the material is so strong — you'd be wrong. In fact, you can easily spot damages from power washing concrete by looking for lines, pitting, and overall surface deterioration. So, can power washing damage concrete? In a word, yes.
Does white vinegar clean concrete?
In addition to its chemical complexity, concrete is intricately spongy and thus really hard to clean up. It may not look like it from the outside, but concrete is full of microscopic pores that allow a concrete structure to grab onto chemicals and sometimes “breathe” them back out.
Why is my new concrete dark grey?
Concrete will continue to lighten until it is fully cured. Allow the concrete to cure at least 30 days before inspecting it for color match or appearance.
What turns concrete brown?
Although the bulk of the hydration process takes place in the hours and days immediately after the pour, concrete needs 28 days to fully dry. While the slab will harden and lighten in color before 28 days, don't be fooled into thinking it's done hydrating.

This White Concrete Stain is a water-based stain that offers a decorative natural appearance for concrete floors, brick, plaster, and natural stone. White Concrete Stain Features: Low Odor.
What is the best natural cleaner for concrete?
As moisture rises to the surface of the concrete, it carries with it the calcium salts from within the concrete. These react with CO2 at the surface, forming that white powdery dust. It can be worsened by exposure to moisture, such as rain. With no moisture movement, there is no efflorescence.
How do you remove ingrained dirt from concrete?
Concrete goes from a dull, rough surface to a shiny, smooth, polished surface through a series of grinding steps. This grinding is done with a series of diamond impregnated floor pads. These pads contain millions of microscopic diamonds that are used to grind the concrete and make it smoother.
Does power washing damage concrete?
Tree root growth and seismic soil movement can contribute to water-related damage in concrete structures. Settlement cracks can lead to water entering the dense material, affecting its integrity and causing it to degrade over time. Plumbing leaks can also cause major damage to a concrete foundation.
Why is concrete so hard to clean?
Discoloration. Another sign of water damage is discoloration. Because of the presence of water, one area of the concrete will be darker than another. As a result, if you notice darkened and discolored areas in your concrete, there's a good chance moisture is causing damage.

There are several ways you can enhance the appearance of your concrete surface, such as staining, scoring and additional paving. For example, if you want to modify its color and texture appearance, just stain the surface and seal it to prevent future degradation.
How long does it take for new concrete to turn white?
HYDROCHLORIC ACID - also known as muriatic acid or spirits of salts - is a concentrated, fuming acid suitable for all technical grade applications. It is most commonly used for brick cleaning or concrete etching because of it's ability to dissolve hardened cement quickly without attacking hard stones or brick.
What does white vinegar do to concrete?
Basically what you need to do is to sprinkle glow in the dark powder on wet cement or concrete. If it is not wet, you should spray a layer of clear paint to make the surface sticky. Once this is done, sprinkle the glow powder over the concrete or cement surface.

The polishing process begins with a 50-grit diamond resin pad instead of a metal segment. When using the resin pads the steps may be 100, then 200, 400, 800, 1600 and finally 3000+ grit. Throughout the process, a densifier is used to harden the concrete surface, which allows the concrete to be polished.
Can I stain my concrete white?
Allow new concrete to cure for at least a month before applying stain. Use a plastic airless sprayer for acid staining. Metal parts are prone to damage and corrosion. For water-based stains, spray the area in circular motions to avoid pooling on concrete flooring.

Using a concrete stain is a much better method to color a concrete patio. Stain actually penetrates the surface of the concrete instead of just coating the surface as paint does. There are many tinting colors available. Greens and browns are also commonly used to accent or blend with landscaping.
What makes concrete look shiny?
The resulting low water-cement ratio affects the hydration of the cement ferrites, which contributes to a darker color. Concrete surfaces that are troweled too early will increase the water-cement ratio at the surface and lighten the color. Concrete which is not properly or uniformly cured may develop discoloration.

Crushed and sorted
“When you demolish a building made of bricks or concrete, you crush the demolition waste and sort the rock from the sand in order to reuse the materials to make new concrete. These recycled construction aggregates all have potential applications where you might otherwise use natural raw materials.
How do you make concrete shine again?
The exact proportions of water, cement, sand, and rocks (as well as other ingredients you can add) gives the properties of the resulting concrete. But once the chemical reaction is done, you can't get the original ingredients back. Fun Fact: The chemical reaction is exothermic - it creates its own heat.
