Automotive Refinishes – SUBSTRATE TREATMENT

Substrate Treatment In The Repair Area



A- PAINT REMOVING & CLEANING

  1. Paint Removing:

    Remove flecks of old paint with a scraper, sandpaper, or SIP Paint Remover.

  2. Detergent Wash: 

    Remove dirt and water soluble contaminants by washing with detergent and hot water solution. Rinse well and wipe surface thoroughly with a clean dry cloth.

  3. Solvent Clean

    Remove grease, oil, and other contaminants with thinner S100 or S501, then wipe surface thoroughly with a clean dry cloth.




B- GRINDING AND FEATHEREDGING

Grind and feather the edge of the old paint using 80 grit treated sandpaper.




C- FILLER APPLICATION

  1. Fill imperfections of damaged area using PE Putty.

  2. Shape filler using firm pressure to bond well the filler to the substrate and to prevent entrapment of air bubbles inside the putty.

  3. It is recommended to apply filler in thin coats (< 2 mm) with a total thickness not exceeding 6mm.

  4. Allow filler to dry then sand repaired area using 180, 240 then finish sanding using 320-400 grit treated sandpaper.

  5. Remove sanding residue using air pressure, then clean by thinner S100 or S501.

    Note: For maximum corrosion protection it is recommended to apply a thin coat of epoxy primer EPX02 “White” to bare substrate before filling.





D- PRIMING & SURFACING

  1. Apply 2-3 medium coats of SRT primer / Surfacer (AC2) and allow each coat 5-10 minutes to flash until hand slick. “If needed, for extra flow, an additional amount of thinner S507 (25%) may be added to the primer/surfacer”.

  2. Sand SRT primer / Surfacer (AC2) with 180-240 grit treated sandpaper. Then finish sanding with 320-400 grit treated sandpaper.

  3. Remove sanding residue using air pressure, then clean by thinner S100 or S501.

Notes:

- Before sanding, a special attention should be taken toward dry to sand condition.

- If needed, for best leveling, apply PE putty or AC putty then surfacer again.





E-COATING

" One Component Coating (RNC coat) "

  1. Use conventional sprays gun and adjust air pressure to obtain the best atomization.

  2. Apply several coats of RNC coat to obtain opacity and allow each coat 5-10 minutes to flash until hand slick.

  3. Sand with 1000-2000 grit treated sandpaper to remove dust.

  4. Polish with fine or medium polishing compound for leveling, then finish polishing with ultra fine polishing compound for obtaining gloss.






E-COATING

Two-Component Coating (SRT Coat)

  1. Use conventional sprays gun and adjust air pressure to obtain the best atomization.

  2. Apply several coats of SRT Coat to obtain opacity and allow each coat 5-10 minutes to flash.

  3. Allow SRT Coat to cure according to its curing cycle “drying time”.

Notes:

- Polishing, in general, is not required.

- Use the appropriate thinner according to weather condition and curing method.






E-COATING

Basecoat / Clearcoat System

  1. Use conventional sprays gun and adjust air pressure to obtain the best atomization.

  2. Apply several coats of BAS Basecoat to obtain opacity and allow each coat 5-10 minutes to flash until hand slick.
    After hiding is achieved, it is recommended to apply a low-pressure mist coat in order to prevent marks formation of metallic particles in the paint film.

  3. Allow BAS Basecoat 30 minutes to flash before applying clearcoat.

  4. Apply 2 coats of SRT clearcoat immediately on dry BAS Basecoat and allow the first coat 10-20 minutes to initial dry before applying the second coat.

Note: Polishing is not required.
