Anticorrosive primer to properly prepare paint repairs
The repair of paint usually requires treatment with an Anticorrosive Primer. However, the paint to be treated must be well prepared beforehand. For example, in the case of factory primers, old paintwork and polyester substrates, the substrate must be sanded and cleaned, provided it has hardened and is not bleeding or thermoplastic. Aluminium and galvanised steel sheet, on the other hand, must be cleaned, finely sanded, and then finally cleaned and dried before an Anticorrosive Primer can be applied. Steel sheets must be dry and clean, but most importantly free of rust, release agents and grease. Bare sheet metal should be cleaned, degreased and sanded. Only after such professional preparation does treatment with an anticorrosive agent make sense and only then can a primer effectively protect steel, light metals and other substrates from corrosion.
Notes on the painting process with Caramba Anticorrosive Primer
First, it is important to shake the spray can containing Anticorrosive Primer vigorously. When you hear the mixing balls stop, you should continue shaking for at least two more minutes. Then you can spray on the primer from a distance of 15-20 cm in a circle or in several crosswise passes and then let it dry. After application, the spray head of the can should be sprayed empty overhead. Caramba Anticorrosive Primer Red-Brown can usually be painted over without intermediate sanding. Dust inclusions can be removed with wet sandpaper after about 30 minutes. The primer can also be washed off with white spirit up to about half an hour after application. Incidentally, our Anticorrosive Primer is not sensitive to frost but should be applied at a processing temperature of about 20 degrees.
