How much paint is needed for a q2 wall painting

When planning to paint a wall avoid avoiding having enough paint for a covering coat or too many scraps. The area measure m² is the calculation basis. Since color schemes, intensity, tints, and wall texture are additional variables, other factors must be considered.

Factors influencing consumption

If you buy paint in a bucket, you usually use the manufacturer's information for the m² that can be painted with the content. However, the information usually refers to a single coat on a smooth and moderately absorbent wall. The actual demand is influenced by the following additional factors:

  • Increase the amount by adding tinting ink
  • Intensity and brightness or darkness of the color shade
  • Condition of the wall surface (smooth or rough as in plaster)
  • Absorbency of the substrate and appropriate preparation
  • Color coverage and contrast class Color (1-4)
  • Color with or without solvents, water-based dispersion, lacquer components

Calculation and basic calculation

The general manufacturer's information on the yield in q2 only really helps when a wall is repainted. Prerequisite is an undamaged relatively uniform primer and a color similarity.

After calculating the wall m2, in most cases the result must be multiplied by the number of color layers. If a wall measures twenty square meters and three layers of paint are to be applied, sixty square meters are the measure of orientation.

The orientation measure as a result of the wall measurement is at least a ten percent reserve of color. For each door or Fensterllibibung should be pitched another five percent.

Plaster background and color intensity

Painting plastered exterior walls as on the wall of a house should be covered with a maximum of two new layers of paint. In the quantity calculation, for coarse plaster, up to one-third of the demand should be calculated as the floor area.

Heavily absorbent walls must be properly primed. With the increase in color intensity when painting the wall, it must be assumed that there will be a coat increase of two to five strokes.

Tips & TricksYou can follow the rule of thumb of craftsmen for the q2 requirement. Smooth and low-absorbent surface needs about 100 milliliters, absorbent surfaces such as woodchip or plaster between 150 and 190 milliliters per square meter.
