How can I avoid liability problems with my painting?

  • Lack zieht aufTo avoid adhesion problems, the area to be painted should always be dry, clean and free of grease.
  • For problematic substrates, such as plastics and polystyrene, the appropriate primer should always be used.

How can I avoid runners?

Autolack läuft abRunners in the paint job can be caused by several causes:

  • To avoid this, always make sure that your spray distance to the object is never too low. It should always be at least 15 – 25 cm maintained.
  • Furthermore, the paint should not be applied too thick in a job. Spray several thin layers in the cloister. This refers to the application first of a horizontal, then a vertical layer. The turning points should be executed outside the object.
  • In addition, care must be taken to ensure that all working materials, such as the paint spray can, the object to be painted and the room temperature, have an ideal processing temperature. This is between 20 and 25 ° C.

How do I remove the "white-painted" paint?

  • Lackoberfläche wird weissThe “blushing” of the paint is formed when painted at too high humidity. The gray veil can be polished out after good drying of the paint layer.
  • The optimum processing temperature is between 20 and 25 ° C with low humidity.

My paint peels off and has cracks

  • Autolack blättert abIf no primer is used in the coating of plastics, the paint peels off after the first exposure.
    The paint has no liability on most plastics, so a plastic primer should be used.
  • Furthermore, cracks can occur in a coating if a highly pigmented paint, for example a primer, is painted on a slightly pigmented paint, for example a top coat.

Your paint job should therefore always look like this:

  • Primer – basecoat – clearcoat.
  • Furthermore, cracks form in the paint when the paint buildup is done with different paint types. For the complete painting setup, a product line from the same manufacturer should always be used to avoid incompatibilities.Lack bildet Risse

Why is my painting result rough and does not shine?

  • Lackoberfläche ist rauhDue to a too large spraying distance, the paint no longer runs on the surface. It already dries in the air and settles on the surface as a “spray mist”. This is to be avoided with a constant painting distance of approx. 15 – 25 cm.
  • Another reason for this is the coating of a too hot object or the painting in the blazing sun. If the heat is too high, the solvent on the surface can no longer escape and “bubbles” are created which make the surface no longer shine. This should be avoided by always looking for a sun-protected place with the ideal processing temperature of about 20 to 25 ° C, at a low humidity, for painting.
  • In addition, the gloss of the paint can be reduced by the dust contained in the air and whirled up – always paint in a protected place.

On my paint form wrinkles / my paint swells up

The formation of wrinkles is the so-called “pulling up” of the paintLack zieht auf

  • If a synthetic resin varnish is varnished with another type of varnish or with itself after it has dried out, it will pull up or form a wrinkle. Synthetic resin paints are oxidatively drying paints, i. drying takes place under the influence of atmospheric oxygen. It takes about 6 hours for the top layer of varnish to dry. After this time, the paint should no longer be painted over, as in a renewed paint application and thus by renewed supply of solvents swell the lower layers of paint.

How are the color deviations in my paint?

There are several causes for this:Lackton weicht ab

  • On the one hand it may be because the paint spray can was not shaken up long enough. Before painting, the paint spray can should be shaken for at least 2 minutes, calculated from the audible stop of the mixing balls. This is necessary because the pigments settled on the bottom of the can through storage.
  • On the other hand, it may be because the color used does not cover well and thus the lacquer is applied too low, the primer still shines through and falsifies the color tone.
  • It may also be the painting itself. For metallic paints, the painting result depends on the spray distance. If the spraying distance is too low, the color will be too dark. If the spray distance is too long, the final result is too light. To avoid this, you should first spray dry and compare the color. The ideal spray distance should be maintained at approx. 15 – 25 cm.

Why is my paint sticky and does not dry out?

  • The coating and storage of the fresh paint job takes place at too low temperatures. At temperatures below 20 ° C, the paint dries more slowly because the drying at e.g. NC / AC paints by evaporation of the solvent. The drying is temperature dependent. The colder the slower the solvent evaporates.
  • Also, this may be a silicone resin paint – mostly used in heat-resistant paints. This must be heated slowly so that it dries.

What is a 1-coat paint?

These are all paint systems that do not require overcoating with clearcoat.

What is a 2-coat paint?

The 2-coat paint system is increasingly being used in the automotive industry for metallic shades. In order to be able to repair these finishes in exact shade, a 2-coat paint system is used – as the coloring component, a base coat is used, which must be overcoated with a 2-coat clear coat. The topcoats are characterized by good opacity. However, they are matt without weathering with the 2-layer clearcoat and are not weatherproof.

What is 1C (or 1K) ?

(= 1 component) These are basically all products that are processed without the use of a hardener.

What is 2C (or 2K)?

(= 2 components) These are all products that cure / dry by adding a hardener. In paint spray can technology, this means that the paint and hardener are combined in one paint spray can. The hardener is in a separate container, which is released at the touch of a button and mixes with the paint. The 2-component system is particularly robust and resistant to scratches and weathering, ensuring the highest product quality.

What is oxidative drying paint?

Curing of the paint under the influence of atmospheric oxygen. After curing, it is no longer possible to dissolve with solvents.

What is chemically drying paint (2C)?

The drying takes place by a chemical reaction with the hardener. Once these paints have dried through, they are particularly robust and weather-resistant.

What is physically drying paint?

Physically drying paints are paints in which the drying process is based on the evaporation of the solvents. The paint can be dissolved again with solvents.

Why is the intermediate flash-off time necessary for the coating?

Between each application of varnish, an intermediate flash-off time of approx. 5-10 minutes must be carried out so that no overcoating takes place and no runners form.

What does grip-proof / when is the paint grip-proof?

The top layer of paint has dried, but the surface is still not loadable – after about 3-4 hours

When is a coating loadable?

When the paint has dried completely – drying overnight is optimal, at least 12 hours. The surface is only loadable now.

Why is my used can no longer spraying?

The valve of the can is clogged. It was not empty sprayed after the last use. It is always important to turn it over after the last use of the can and empty the valve.

How should I store my cans?

Optimum storage of paint spray cans is in cool, dry rooms, but never above 50 ° C.

How / Where do I dispose of my empty sprayed cans?

Completely empty cans may be disposed of (household waste, site disposal, etc.).
