So you can color mortar

For dyeing mortar, color pigments are used. They are meddled. The small proportions which are already sufficient for complete staining do not affect the mechanical properties. The base of the pigments consists of iron oxide. With mixed-in particles, the mortar is colorfast and completely dyed.

When coloring, a few percent are sufficient for color saturation

Color pigments are offered as powders and have to be distributed in the dry mixing of the mortar. The following proportions result in the following optics:

  • to one percent: slight tint, depending on the grain dotted texture possible
  • one to four percent: gradual tinting with decreasing tendency to texture
  • five percent: saturated full color, which can not be increased

The Farbpimente and particles have no own binding force. They must "saddle up" on the binder of the mortar, cement or hydrated lime. Therefore, a very thorough mix is ​​required to avoid creating "dusty" mishaps.

Binders affect the coloring

When making your own plaster pavement mortar and other joint mortar should always be used for dyeing a stirrer. Each remaining lump produces after drying and setting a color spot, which settles.

The color pigments can be mixed to create an individual color. The binder and the mixing ratio affect the resulting color. Lime brightens, cement behaves neutrally. To test the result, a test-lump is recommended, which is produced through-dyed at an early stage, in order to wait for the setting process.

Standard colors

As standard colors in pigment form based on mineral iron oxide are available:

  • Dark chrome green
  • Iron brown bright
  • Iron brown medium
  • Iron brown dark
  • Iron yellow shining
  • Iron yellow matt
  • Iron yellow orange
  • Iron red fireplace red
  • Iron red clinker
  • Iron red brick
  • Iron red dark (Bordeaux)
  • iron black

In order to give the coloring more brilliant results when coloring, a white cement can be used with pure cement mortar. It corresponds in its effect about the color image of lime cement mortar. Pure hydrated lime mortar produces the brightest and most brilliant colors.

Tips & Tricks

Physically speaking, iron oxide is rust. Therefore, you do not have to worry about your mortar rusting or corroding. The iron oxide has already passed this chemical process and is completely insensitive to moisture.
