Video: Dispersion Varnish For Airless Spraying. Everything Is Gone With One Swipe
The airless spraying process saves time on large areas. So that masking work and cleaning measures do not destroy them, the coating material must be matched to the application process. A universal single-layer dispersion paint promises a quick-drying spray mist that can be simply swept away, vacuumed or wiped away.

Even though more and more research is being done to make spray application rational and therefore attractive for small areas, it is currently primarily used on large areas, such as in commercial halls.
The spray mist repeatedly causes problems with this undoubtedly extremely economical application process. Because this not only contaminates the floor surfaces in the room where spraying takes place. By sticking the wet coating material to the soles of the shoes, it is also carried into adjacent - often unprotected - areas.
Coating materials that are equipped with the so-called dry fall effect significantly reduce this problem.
Drying when falling
Coating materials with a dry-fall effect are formulated in such a way that the spray particles dry as they fall. Because they arrive on the ground so dry, they can simply be swept away, vacuumed or wiped off the surface without causing any damage. CD-Color has developed a single-layer dispersion paint that meets the criteria of rating class 3 for airless spray application according to the American standard test ASTM D7868–13 (2017). The test setup simulates an overspray that falls from a height of approximately 5.50 meters (if you think of ceiling coatings in large commercial halls, this height should be realistic). The test result certifies that the dispersion varnish has reduced adhesive behavior on horizontal surfaces that are not to be coated. The falling spray mist can be removed almost without residue. The transfer of wet build-up to the soles of shoes in unprotected areas is also significantly reduced. Nevertheless, covering neighboring areas is of course recommended. The set and powdered spray mist can later be easily disposed of together with the cover.
Dispersion varnish for many substrates
Mixed substrates repeatedly cause difficulties with hall constructions. In addition to concrete, sand-lime brick or plaster, it is not uncommon to find wood, non-ferrous metal or plastic. A coating that adheres securely to all of these substrates offers decisive advantages here. "By using adhesion promoters, the single-layer special coating based on pure acrylate adheres directly to almost all load-bearing substrates, such as concrete, aerated concrete, sand-lime brick, plasters and fillers or plasterboard. But it can also be used to rework glass fiber, plastic, wood, galvanized steel, non-ferrous metals, profiled sheets and old coatings.”This is how CD-Color describes the adhesive properties of its innovative coating. This has proven to be very advantageous, for example, when spray-painting ceiling structures with various components: trapezoidal sheets, concrete lintels, galvanized steel beams or ventilation pipes made of aluminum could be coated in the same operation. This simplifies the processes and shortens the processing time, the paint and varnish manufacturer from Herdecke describes the advantages of his coating.
Although the material was primarily developed for use on large areas, it is suitable for all uses in the private or commercial sector, where maximum efficiency is required and odor nuisance is undesirable because the rooms have to be moved into again quickly. Schools and administrations, waiting halls and terminals, production and storage halls, stairwells and foyers can usually be used again on the same day, because the water-based coating can not only be applied quickly, but is already dry after one to two hours with maximum coverage.
CD-Color also emphasizes that the material in accordance with the "Testing Institute for Paints and Paints" fulfills the requirements of the Food Hygiene Ordinance with regard to disinfectability, water resistance and cleaning options. Because of this, it is also suitable for use in food processing companies such as butchers and bakeries, but also in canteen kitchens or food markets. According to the manufacturer, a fire protection report also certifies that the coating has no influence on the fire behavior.
Three different degrees of gloss
In order to meet the different optical requirements, the dispersion varnish is available in three gloss levels. In addition to a noble matt finish, a silk matt quality is available, which is characterized by its robust suitability for everyday use and high cleaning ability. And wherever a scratch-resistant and highly cleanable surface is desired - as an alternative to latex paints or wall lacquers - the silky gloss quality is the first choice. Since the dispersion varnish can be tinted in over 470 color collections and in around 180,000 colors using mixing technology, no wishes should be left unanswered with regard to the color design.

The dispersion varnish described is offered by CD-Color under the name Lucite All-In in the three gloss levels Edelmatt (Lucite All-In 5 Matt), silk matt (Lucite All-In 10 Velours) and satin gloss (Lucite All-In 15 Satin).
