Aprende a pintar colores plata y esfumarlos con blender sistema bicapa base color Pintura Automotriz

Summary

The video demonstrates repairing and repainting part of a truck using metallic silver basecoat and blending techniques. The goal is to match the new paint to the original finish without creating a visible difference in tone at the panel edges.

Preparation

• The damaged area has already been repaired and prepared with a 2K polyurethane filler primer.
• The presenter says the primer resists solvents well, helping prevent the basecoat from soaking in and causing a loss of gloss or other finish problems.
• The primer is described as light gray, which can help with coverage. For darker colors, the presenter suggests adjusting the primer shade with a universal primer.
• Sand the filler primer after it dries, even if it looks smooth, so the next coating has a surface to adhere to.
• The sanding sequence used is:
  • 400- and 600-grit for leveling the primer.
  • 800-grit on the existing painted area.
  • A coarser grit where the clearcoat blend will be made.

Preparing and Applying the Metallic Basecoat

• The presenter uses an HVLP spray gun with a 1.3 mm nozzle.
• The suggested starting setup is about 1 bar of pressure, with the material flow and fan adjusted and checked by spraying a test pattern. The presenter fine-tunes the settings during the demonstration.
• Mix and thoroughly homogenize the metallic basecoat before use so the pigments and aluminum flakes are evenly distributed.
• The basecoat is mixed 1:1 with basecoat reducer. The presenter warns against using an unsuitable general-purpose thinner: it may weaken adhesion and flexibility, make the coating brittle, and prevent the metallic flakes from settling evenly.
• Apply the basecoat in stages:
  1. Paint the repair area from the outside inward.
  2. Apply two semi-wet coats to cover the repaired spots, allowing about five minutes between coats.
  3. Apply a third coat to begin arranging the metallic flakes. A fourth coat may be used as a control coat if needed.
• To reduce the chance of a visible color mismatch, blend the color outward rather than painting a hard edge at the panel boundary:
  • Use sweeping, often diagonal passes that gradually fade into the original paint.
  • Avoid extending the color to a sharp cutoff where it can be compared directly with the original finish.
  • Use judgment about which parts of the panel need full coverage and which should be feathered out.
• For the control coat, the presenter moves the gun farther away and applies a light, broader pass over the wet basecoat to help even out the metallic flakes.

Applying Clearcoat and Blending the Edge

• The presenter prepares a polyurethane clearcoat called Clara Plus. The transcript’s stated mixing ratio and spoken measuring example are unclear, so check the product’s technical instructions for the correct proportions.
• The clearcoat is applied with a 1.4 mm nozzle, about 1.5 bar of pressure, the fan fully open, and roughly three turns of material flow; the settings are then adjusted as needed.
• Apply three coats:
  1. A semi-wet first coat over the area to be cleared.
  2. A medium second coat after the first has flashed off. The presenter checks readiness by ensuring the clear is no longer tacky or stringing.
  3. A third finishing coat for gloss and film build.
• Stop the clearcoat short of the blend boundary rather than carrying it to a hard edge.
• Use Tecnoblender to soften the clearcoat transition. Apply only a light mist at low pressure over the blend edge; too much blender can cause runs or other defects.
• The presenter says this clearcoat has a relatively slow evaporation time and recommends allowing ample time before polishing. The video mentions polishing after roughly 24–76 hours, but the presenter personally prefers waiting 25–30 days for curing.

Main Lessons

• Careful surface preparation and sanding are essential for adhesion.
• Use the reducer intended for the basecoat, especially with metallic colors.
• Metallic color matching depends not only on the formula but also on how the flakes are distributed, so gun setup, spray technique, and a control coat matter.
• Gradual color and clearcoat blending helps disguise small differences between the new paint and the original finish.
• Use the blender sparingly and allow adequate flash and curing time; the presenter prioritizes finish quality over fast turnaround.
