Methods and means determine whether the covering is successful. Both the substrate and the paint must be prepared according to the preconditions. The right choice of brushing tool, how to use it and the speed of the application also help the opacity. External conditions must also be observed.
The amount of color pigments determines the opacity
As general and frequent tips, anyone who wants to paint will be told that they shouldn't skimp on the quality of the paint or varnish. To put it somewhat simply, manufacturers of cheaper and cheaper products save on adding color pigments. This automatically leads to a loss of opacity. The supposed savings effect is often lost due to the higher amount that has to be applied in several layers.

In almost all cases, a primer helps to achieve the opacity of the upper layer of paint more quickly. In addition to the lower quantity required, the primer also compensates for uneven suction. Normally, almost all painting tasks should be calculated with one application of primer and two coats of paint. A top coat is often sufficient on well-preserved old paintwork.
Uniformity in all work and execution steps
The following factors should be carried out in the greatest possible uniformity to achieve maximum coverage:
- Quantity of the paint applied
- Suction behavior of the subsoil
- Continuous wet-in-wet painting
- Color length receptacle of the string tool
- Matching string tool for the texture of the coating area
- Grinding state on the entire area
- Well-converted color with homogeneously distributed color pigments
- No draft and constant temperature between ten and 25 degrees Celsius
Special features of different substrates
On wood, tanic acid and lignin can penetrate when the color application is too thin or without primer or possibly depth reason (€ 4.81 at Amazon *). In particular, oak wood is prone and must be well pretreated.
When painting bare precast concrete elements on ceilings, in some cases gluing on a piece of waste and then painting can be less work than painting directly.
If the painted woodchip wallpaper becomes stained, it is often due to the different degrees of intensity of the paste. Here, too, a primer can compensate. When wallpapering, it is important to ensure that the paste is applied evenly.Tips & Tricks Colors are available in four opacity classes, with one having the best opacity and the four producing the weakest opacity. This class deteriorates significantly when diluted with water. ",
