Recipes and creating concrete pigment

Modern building technologies allow to avoid the dullness in the architecture by adding pigment for concrete.

Coloured concrete used in construction of various designs.

addition to the impact of the pigment in the appearance of the concrete are improved further and the quality characteristics of the material.

Industrial construction and production are also widely used pigment for coloring various products, but also produced concrete coloring and artificial stone with their hands.

Before staining, it is necessary to know what is a pigment and what properties.

What pigment?

pigment for concrete - is the addition of the ink carrier, which gives color.After drying, the concrete is not capable colorants dissolved no liquid.

If good quality pigment, it is resistant to UV rays and all weather conditions.

By origin pigments are divided into:

• organic: yellow, red, blue, green, brown;
• mineral subdivided into natural (kaolin, chalk, graphite, lime) and artificial (chromium oxide, carbon black paint, blue);
• metal: Golden bronze, aluminum powder.

to create natural dyes destroy dry natural raw materials, and artificial pigment - Mineral materials are heat-treated.

dyes may have the form: powder, emulsion, paste, and microcapsule.

pigments have the following properties:

1. Corrosion resistance;
2. Thermal stability;
3. Lightfastness.Under UV keeps the original color;
4. Spreading.The ability to override the original concrete color (white or gray);
5. dispersion.For very fine grinding the fine particles have a high coloring power;
6. Chemical resistance.The pigment is not destroyed by alkali and cement;
7. Oil absorption.The ability to hold pigment oil (binder composition).The lower the score, the more lasting color.

concrete staining in two ways: staining solution during mixing and dyeing ready-mixed concrete.Staining of ready-mixed concrete is similar to conventional painting of walls.

In this case it is necessary to use a deep penetration of formulations suitable paint over the concrete 2 mm.

designs made of colored concrete solution is more robust, since the material has a long life and does not require touch-up.

Disadvantages include high cost, since quality of color need a large quantity of powder coloring.

Therefore, to reduce the cost often resort to the use of the dye prepared with their own hands.

Production and use of dyes

dyes can be of the following types:

• acid;
• acrylic;
• simple;
• dry;
• color additives.

any sale of pigments is carried out in many specialized stores, but because of the high prices there is a method of preparation of the dye by hand.

consider manufacturing hlorkislogo dye, which would require the following components:

1. 7 liters of clean water;
2. 0,5 kg dry lime paint the desired color;
3. 0,2 l of calcium chloride;
4. 1,5 liters of hydrated lime;
5. soap per 30 g per 10 liters of finished paint.

hydrated lime and lime paint should be mixed thoroughly in water, then add to the mixture of calcium chloride.Soap grated to grind and dissolve in warm water and then added to the solution.

mixture should be stirred and passed through cheesecloth.This way you can get any color:. Brown, green, red, etc.

Painting cooked with his own hands, of course, is very competitive, but industrial pigment still has a higher quality.

Acid Dyes

Acid dyes are the most popular for coloring concrete.The basis is iron oxide pigment.Iron oxide pigments are colorless powder.

powder when added to a concrete solution enters into a chemical reaction and provides the desired color.There are eight shades. Black, red, yellow, green, brown, etc.

To use an acid dye required solvent additives for fastening, adhesive.First it is necessary to mix the dry ingredients, then add liquid.

pigment necessary to put on a clean and dry surface with a sprayer or acid-resistant brush.

adjacent objects to be protected from the effects of acid that destroys the fragile items.A person who makes coloration must be in a special suit and gloves.

After 6 hours the excess paint and acid should be washed off with water, then during the day you need to thoroughly dry the treated surface.

Iron oxide dyes can give concrete form of stone or old product.

production uses iron oxide coloring in coloring concrete for paving slabs, paving stone, artificial stone, roofing tiles.

Iron oxide components are given the color that will be eternal, as it is not washed off and does not burn.

also iron oxide pigments are used in a variety of oil-based paints: epoxy, alkyd, etc.

To prepare 50 kg of colored concrete consumption of dry pigment is 0.5-1 kg, how much pigment to add - it depends on the wishes of the color:. The brighter the color needed, the greater the need to add the pigment, and also depends on the color.

For example, if the color is brown, the amount of dye should be 6% of the amount of cement in a solution.

For kneading colored concrete with their hands need to comply with the following proportions: 1 part cement, 2.5 parts sand, ¼ of the water, 4 parts of gravel and 2% of the dye.We recommend using white cement.

acrylic dyes Acrylic

dyes used where needed durable and bright color.Ideal for walls and floors.There is a wide range of colors.

Acrylic dyes are used to color concrete indoors and outdoors.It can be used for artificial stone.

Benefits include the fact that acrylic paint dries quickly and lasts a long time, but it is very important to choose good quality dye.

suit and a brush and a roller, and a sponge to apply the pigment.However, a low-pressure sprayer allow paint very quickly.

To increase the brightness of the two pigment layers can be applied.

Simple dyes

Simple dyes has a wide range of colors and are the brightest.If you choose a low-quality dye, the color will burn out quickly when exposed to sunlight.

Therefore, these pigments are best to use on the premises.Presented in the form of a powder, diluted with water and the solvent.They can be used for artificial stone.

Dry dyes

Use dry pigment delivers incredible brightness and excellent for outdoor use.Artificial color pigment is resistant to all kinds of weather, light and humidity.

But this dye can be used only for the new concrete has not passed any treatment.Also dry pigment reinforces concrete structure.

When selecting dry dye need to pay attention to the color of the powder was uniform, without lumps.

Dry color pigment does not dissolve in water, and after some time the solvent accumulates on the bottom.These include ocher, white, umber.

Applying the mix dry pigment is carried out with a spatula.When staining solution must be constantly stirring.

Colored supplements

Additives used it to create a colored material.There are powdered or liquid and added to the raw concrete only during preparation of the solution.

Present mainly bright and pastel shades.Since the stain all of the material, the color does not change either under the influence of weather or by mechanical action.

color lasts as long as the entire design.

Colored additives can be used for artificial stone, then the dye is added to plaster solution Mixing.

Modern technology has repeatedly proven that colored concrete with their hands can make each builder.
