Colored cement, dye (paint, pigment) for cement, mortar and concrete at home

There are endless ways to improve the appearance of your concrete projects with colored cement. Whether you’re working on a driveway, patio, or interior design elements, adding color can turn boring, gray concrete into something colorful and distinctive.

It’s not as hard as you might think to add colors, paints, or pigments to your cement, mortar, or concrete mix. These color-changing additives can be added directly to the concrete before it is poured, providing an evenly distributed color throughout. They are available in a range of hues. Any concrete project can benefit from the creativity and customization that this technique offers.

The durability of colored concrete is one of its main advantages. Pigments mixed into the concrete are an intrinsic part of the material, in contrast to surface paints that can fade or chip. This indicates that the color will withstand weather, wear, and time just as long as the concrete does.

Start small at home with do-it-yourself projects like custom-colored concrete countertops, colorful stepping stones, or garden borders. These projects improve your area while also being enjoyable and fulfilling. With the correct supplies and a little imagination, you can produce results that look professional.

Types of dyes

The purpose of cement paint is to alter the solution’s natural gray color to any desired shade. These days, you can completely change the color of gray structures and products to a fairly bright one, or you can just give them a light tint thanks to the wide range of coloring options available.

• Substance in powder form
• Special pastes with rich color in high concentration
• Emulsions
• Small capsules with dye

Paint comes in two varieties: natural, which is made from materials found in nature, and synthetic, which is made by processing specific chemicals. It is imperative that you thoroughly research the painting technology, features, allowable operating conditions of the painted surface/product, and other significant attributes and properties before selecting a cement dye.

Pigment

Pigments are a type of filler used in concrete that alter the material’s characteristics—in this case, color—during mixing or after it has solidified.

Cement pigments are unique additives made from natural or synthetic raw materials that come in liquid, powder, or emulsion form. They are used to color concrete, either while it is being mixed or when it is applied to a monolith that has already been completed. Concrete can have a desired color that ranges from a light shade to one that is highly saturated and bright thanks to pigment.

Any pigment or additive to the solution must be mixed with fixatives, solvents, and other unique materials to speed up the composition’s drying process and increase its resistance to outside influences.

• Water – for acrylic compositions
• White spirit – for dissolving alkyd resins
• Drying oil – for oil pigments
• Acetone – interacts well with nitro paints

What is it

It is essential to thoroughly research all current compositions, their characteristics, and operating environments prior to painting cement. The majority of compounds on the market can be broadly categorized into two groups: those that are used to color concrete while it is being prepared and those that are used to add color to surfaces that have already hardened.

Experts contend that incorporating pigment into the mixture at different phases ensures a more consistent and intense hue. Furthermore, this type of dye prolongs the operational surface duration, the color itself endures for an extended period, and it nearly remains unaffected by adverse external influences.

Cement Caemen may be synthetic or natural. The chemical formula of the material directly affects how saturated the shade is. However, the amount of pigment added has less of an impact on the shade’s brightness.

Furthermore, it is important to remember that using more pigment per cubic meter than is allowed can seriously impair the concrete’s ability to function as intended.

When considering how to paint concrete, consider the color. The material of the composition affects the shade as well. Thus, red iron oxide is used to produce red, and titanium dioxide is used to produce white. In industry, manganese, iron oxide, and chromium oxide are also widely utilized.

Types of pigments

A color pigment can be liquid, powdered, encapsulated, or any other consistency. Here, each master selects the technology and application that best suits him.

Mineral and organic dyes can be distinguished from one another based on their origin and heat resistance. However, the primary distinction is made based on the mode of production, which dictates the properties and applications of the pigment.

• Natural – produced by crushing ocher, kaolin, lime, manganese peroxide and other substances.
• Artificial – obtained by processing stones and minerals with temperature. Chromium oxide, azure, painter"s black, titanium white, burnt umber, etc. are used.d.
• Acidic – is produced on the basis of different acids: in this way they get brown and black, green and blue colors.
• Metallic – using metals (zinc dust, golden bronze, iron oxide powder, titanium oxide, aluminum powder).

Properties

Every pigment has specifications that must be met; if they are not met, the dye cannot be applied to the solution or the final surface. Although there are several general requirements, properties are defined by the painted surface’s operating characteristics.

• Overall coverage – the ability to cover the gray-white tone of the material.
• Dispersion – high-quality distribution over the finished mixture or monolith.
• Low oil absorption – maximum 40-100 units, which indicates the duration of retention of the shade by the finished solution.
• Good resistance to corrosion, ultraviolet radiation, alkalis, sudden temperature changes and other external factors.
• Long service life – so that the concrete does not lose its color after a year.

Production methods

You can make cement pigments at home with your hands or in a factory. In the manufacturing process, certain synthetic additives are added to organic and mineral materials to create dyes. These materials are usually characterized by superior qualities, resilience, luminosity, and proper usage as directed.

Although they don’t always produce the desired result, self-made dyes can also be used for painting, but use extreme caution when using them.

Characteristics and properties of pigments

You must carefully consider all the features and parameters before deciding which paint to use on a finished surface or to add to the cement mortar.

Required qualities

The paint needs to fulfill specific requirements in order to guarantee its durability, give the desired color, and be evenly distributed over the surface or solution.

• Fraction – relevant for powder dyes and other types. The smaller the particles in the pigment, the more reliable and uniform the color will be, and the painted surface will be well covered.
• Sensitivity to light – the ability to maintain the saturation of the shade without changes, not to fade. Especially important for paints used outside buildings.
• Oil absorption – the ability of the composition to retain the volume of oil.
• Resistance to alkali – determines the features of contact of the pigment with cement.
• Resistance to corrosion.
• Comfort in work – the fewer products you need to use and manipulations to perform, the easier the paint will be to use.
• Guarantee of obtaining the desired color – also very important. The shade may vary within small limits depending on the color of the cement and other parameters, but in the end it should be as specified by the manufacturer.

Primary dye colors

The pigment’s shade and the properties of how the constituent materials interact with one another determine the color of the painted or concrete surface. The color of the cement has a big impact on this parameter, so white is the brightest and most accurate shade; gray is also a good option for muted colors.

When painting during the mixing stage, it is crucial to accurately observe the proportions and make sure to test before creating a large volume of solution.

The majority of pigment manufacturers only offer the standard hues of blue, red, green, black, and yellow. You can get secondary shades like orange and purple by mixing them in the proper ratios. White Portland cement is mixed with an equal-colored filler to produce a white solution. Gray cement can be made lighter by adding titanium dioxide.

• The shade of sand, other fillers – the darker the color, the more saturated and less bright the result will be. Bright colors can be achieved using transparent quartz sand, light crushed stone, white cement.
• Water-cement ratio – the more water, the lighter the solution and the brighter the color.
• Concrete hardening temperature – at high temperatures, the crystals formed during the hardening of the mixture are smaller, the light is scattered better through them and the shade seems lighter.
• Percentage of pigment in the total mass – before painting the cement mortar, you need to study the instructions for the dye. The colorant is added to the solution in a volume of 8-10%, no more. Actively coloring compounds are introduced in a volume of 5%. Then the difference in shade will not be very noticeable, but the characteristics of the concrete may deteriorate. Usually pastel colors require the addition of 1-3% of the total mass, medium in intensity – about 3-4%, the brightest and most saturated – 4-6% or more.
• Manufacturer – the production method, the accuracy of compliance with the technology, the raw materials used can give different results for the same color of pigments from different manufacturers.
• Time – the service life is determined by the composition and method of painting: oxide dyes retain their shade for a very long time, for example. Over time, lime stains (efflorescence) may appear on painted surfaces.

• Green – from chromium oxide
• White – from titanium dioxide
• Yellow – from iron oxide of the corresponding color
• Red – from iron oxide of this shade
• Black – from black iron oxide

The variety of colors and shades offered by manufacturers is always growing, so picking the appropriate paint composition to get the desired effect won’t be hard.

How to choose the right cement

The type of binder used has a significant impact on how paint behaves on surfaces and cement mortar. Any brand of cement can be used thanks to technology, but the final shade will vary depending on the powder’s color.

• Gray Portland cement after hardening becomes dark gray, with a dirty undertone, muting bright shades.
• White cement has almost no effect on color change and is most relevant for obtaining a bright and juicy, light shade.

The coloring composition has an impact on the outcome as well; the type of pigment used determines the shade’s saturation and depth. Doing a test, or trial batch, is preferable to speculative analysis to determine final outcomes under particular circumstances and materials. You cannot, in any case, exceed the pigment concentration in concrete since doing so will have a detrimental effect on the strength and quality of the solution, possibly leading to cracks and disrupting the hydration process.

Types of dyes

You can use a range of coloring solutions to color cement or concrete. A lot of the decision-making process is influenced by the object to be painted and the intended use (sculpture or garden path, concrete blind area or basement of a house, etc.). d.).

Acid dyes

When acid dye is added to concrete that has already hardened, it reacts and leaves behind insoluble deposits of the original color in the pores. In order to strengthen and bind the surface and increase wear resistance and service life, the pigment penetrates the monolith to a depth of approximately 1 millimeter without forming a film.

An acid dyed concrete exhibits a relatively high level of fading resistance. Ideal for paving slabs, plaster, concrete floors, ornamental brick, artificial stone, etc.

Acrylic dyes

The human safest type of dye that can be used both indoors and outdoors. Paints quickly and can be applied multiple times to achieve the desired color. This is the least expensive and most economical wall painting option that ensures long-lasting, high-quality color saturation.

Dry dyes

Using a trowel, dry dye is applied thickly to freshly mixed concrete. This process calls for specific expertise or at the very least practice on a trial surface. provides a large selection of shades that are resistant to a variety of unfavorable elements (weather, temperature changes, and ultraviolet light).

The powder’s color pretty much matches the hue that the painted concrete will take on. Only recently laid concrete surfaces—ideally untreated and unpainted beforehand—are suitable for the application of the dye. The monolith is strengthened by the dye.

Since the material cannot be dissolved in water, uniform coloring and homogeneity of composition are important considerations when selecting a dry pigment. Using a spatula or trowel, apply the material in an opaque, thick layer.

Simple dye

You can even make simple dyes with your hands. They typically come in a variety of shades and are produced in powder form. When making a decision, one must consider the substance’s quality because inferior dyes fade quickly in the sun, are not as resilient to weather, and need to be colored constantly.

Simple dyes are typically utilized to decorate rooms. Mix the powder with a solvent (usually water) to create the final composition, then apply and let it dry completely.

Color additives

These kinds of dyes let you paint concrete while it’s still being mixed. Powdered or liquid additives are added to the mixture; pastel colors and light shades are the most common types. The color is permanent, lasting just as long as a concrete building. There is a wide range of options, and the operating technology is straightforward.

Methods for coloring cement mortar

You can achieve the longest-lasting color that doesn’t need to be updated frequently by coloring concrete during the preparation process.

• When mixing concrete, add one pigment of the desired color in the volume specified in the instructions.
• A mixture of different shades is poured into the form, creating original decorative effects (single production).
• Several additives are added to the mixture in small concentrations with shades of one color, creating an original texture of natural stone with veins.
• The mold for pouring concrete is coated with pigment inside, and then the solution is poured.

Mixing the dye with cement

The first step is to choose an appropriate pigment in the desired color. Typically, the packaging specifies the outcome based on the amount of pigment added to the blend. After thoroughly mixing all the ingredients of the solution, the pigment is added (preferably in a concrete mixer).

Coloring compositions for the solution are typically utilized in situations where it is required to guarantee the highest level of resistance to mechanical loads, atmospheric influences, and abrasion. As such, selecting a pigment needs to be done with extreme caution.

• Resistance to ultraviolet radiation, acting over a long period of time.
• Water resistance – the pigment should not dissolve, blur, or be washed off with water.
• Alkali resistance.
• Keeping the color unchanged for a long time.

Testing before work

You must test before beginning work to ensure that the final product will be of the highest caliber and that the color will match the intended one.

• Make a trial mix (with an exact measurement of the components, in the same conditions where the main material will be prepared).
• Add the pigment to the solution, which is supposed to be used, in the required volume.
• Pour concrete and look at the result.
• If the solution is too light, and the optimal amount of color is used, choose another pigment, and do not increase the volume of the existing one, since exceeding the volume of dye will cause rapid evaporation of moisture from the monolith and the appearance of cracks, deformations.
• If you still need to introduce a lot of pigment into the solution, it is advisable to combine it with the addition of a plasticizer that can retain moisture and ensure normal hydration.
• To avoid the appearance of gray spots and dark spots in concrete, you need to mix it very well and for a long time.

Applying paint to the finished surface

This technique is comparable to standard painting on various surfaces. Concrete, on the other hand, is different in that moisture can seep into the surface’s uppermost layer, which is used to fortify and shield the monolith during painting. Painters typically use deeply penetrating compounds (up to 5 millimeters) that change color over nearly the whole structure/surface life of the concrete.

Different components (usually not water) can be used to create the composition colors and impregnates. When making your selection, consider the extent to which the composition has permeated the concrete, the degree of leaching, and the shift in shade caused by the weather. Painting surfaces that don’t endure a lot of mechanical stress or constant negative impact is appropriate for this technique.

Advantages and disadvantages of colored cement composition

The best outcome in terms of coating resistance to different impacts is colored concrete; this type of concrete doesn’t wear off or require frequent touch-up painting because the internal color is retained even after the top layer is removed because the painting was done on the entire monolith rather than just the surface.

• The ability to get any color and shade by mixing pigments.
• A chance to create pigments with your own hands, saving significantly.
• Economical consumption of dyes – a small amount of pigment is enough to get a saturated color.
• Safety of substances for human health and life.

Among the drawbacks, the possibility of the concrete surface turning yellow, the emergence of dirt, and erosion are noteworthy. Purchasing a pigment can be costly if painting a significant amount of the solution. Furthermore, autonomous dye production doesn’t always produce the desired outcome.

However, contemporary producers provide a sizable assortment of superior goods that essentially do away with all the drawbacks and hazards. Any composition can be purchased in Moscow as well as the surrounding areas.

For DIY projects, colored cement and dyes can turn plain cement, mortar, and concrete into colorful, customized surfaces. You can achieve a range of colors by combining pigments, which improves the visual appeal of indoor floors, patios, and driveways. Homeowners can add a distinctive touch to their spaces without requiring professional expertise thanks to this easy-to-use process.

Independent preparation of dye

Accurate ratios and technology are necessary when making a dye by hand. Getting the right color and keeping air permeability while stopping moisture from seeping into the concrete are the two most important painting tasks.

• 7 liters of industrial water
• 500 grams of dry pigment based on lime
• 5 liters of hydrated lime
• 250 grams of calcium chloride
• 03 kilograms of ordinary laundry soap

To make the pigment, slake the lime in half a bucket of water, then take a liter of the mixture and dilute the dye. Make a laundry soap solution with the remaining liter of slaked lime. Next, combine all ingredients in a shared container and strain. If you paint vertical structures, you can add an acid-based gel-like substance to stop the dye from flowing.

• Mix the adhesive base, solvent and additional compounds (to fix the result) until a homogeneous consistency is obtained. Add a special coloring additive.
• Work with the substance only with the use of personal protective equipment – rubber gloves, work clothes, glasses.
