PPG Basecoat Blending Waterborne SOP (PD-0706WB)
Вставка
- Опубліковано 12 бер 2020
- This standard operating procedure (SOP) covers the process for successfully blending a basecoat using a waterborne finish. Before beginning any repair, it is important to always wear the recommended safety protection required for the job.
Follow along with the outlined process below for the first steps in achieving a flawless finish.

PD-0706WB: BASECOAT BLENDING - WATERBORNE STANDARD OPERATING PROCEDURE
----------
1. Identify Color Formula
Identifying the correct color formula is the essential first step in achieving a good match with waterborne basecoat. Look up the vehicle color using a color retrieval tool and identify the location of the corresponding chip deck in the waterborne color box.
2. Check for Variant Chip
Check for a variant chip that provides an acceptable, blendable match.
3. Prepare a Sprayout Card
If necessary, prepare a sprayout card, using the correct G-shade card recommended by the formula. Sprayout cards, or a letdown panel, are required for tri-coat, quad coat and translucent colors.
4. Apply an Approved Sealer
After checking to determine that all panels have been prepared properly, apply an approved sealer, using the recommended G-shade for the basecoat color. Apply just enough sealer to cover the primer surfacer area.
5. Blend the Sealer Edges
To create a smoother transition, melt in the sealer edges using a blending solvent. Or, after the sealer has dried thoroughly, lightly scuff the sealer edges with P800 grit sandpaper.
6. Appy a "Wet Bed" to the Repair Area
Applying a color blender to the repair area-extending just beyond the color blend-will create a “wet bed”, which can also assist in blending, especially for metallic and pearl finishes. This process is spelled out in the product information bulletin.
7. Mix the Basecoat
Mix the basecoat following the reduction instructions closely.
8. Check the Viscosity
Once the color is mixed, check the viscosity using a DIN 4 cup. Ideal viscosity should fall between 23 and 28 seconds.
9. Thin Viscosity if Needed
If the viscosity is greater than 28 seconds, it’s too thick. Thinner will need to be added. Start by adding 5% more.
10. Apply the Basecoat
After tacking off the area, apply the basecoat. Keeping the gun 6-8 inches away from the surface, apply medium light coats with a 75% overlap. Keep the gun aimed straight at the repair-no wrist flicking.
11. Applying Additional Coats
Use a handheld blower or similar tool to flash each coat to a matte finish before applying the next coat. Step out each coat further than the previous to create an invisible blend.
12. Apply Control Coats
After checking for coverage and the color coats have dehydrated thoroughly, reduce the gun’s air pressure and apply 1 to 2 light “control” coats to achieve proper orientation of the metallics.
13. Apply the Clearcoat
After flashing for 15 minutes and lightly tacking off the repair area, apply the clearcoat according to product instructions.

I am so glad i use spies hecker. So mutch easyer to work with, and it takes half the time to paint
Good
Anyone else notice how the car come out of the booth already reassembled.
I tell my helpers to put primer according to the color of the car this way I don’t have to put sealer
Ya your prep work needs to be on point then. I had a guy who would do that but he would finish sand with 400grit. Waterbase you cant do that.. after a day or two all those scratches woukd start to show up. Once that clear starts setting up. On silvers i wont put sealer but i finish sand with 800 or 1000. I get what your sayin. It saves alot of time but like i said, you better make sure your prep work is 100%
agreed save consumption cost too
Just be aware that primera won’t give you the exact G shade that you’ll need for specific colors, even if your primer color is close to the desired shade, the sealer would give you a better color!
never thought about that
Wow......how do you make money with this stuff.....Spiesblows this out of the water....wow
Spies is So good that even our PPG reps say so.... Especially for color matching.
people still use viscosity cups?
@Mike G
They are very handy!
Painters that follow the TDS do.
It ensures consistent results.
Its difficult to use a wall paint on cars ?
No.. you buy wall paint and mix with petrol then spray through gun makes nice finish
@@craigyboy4770 that exactly I said ?but explain what kind of petrol, petroleum,or whatever you mean maybe PPG has it already for you inside check out your exterior water based wall paint its a gel coat
I've no idea where Craig boy is coming from? But I have only tested it once from blending through to respray.
I used Craig & rose which was the closest colour to moondust silver "Ford mondeo" I thinned it out with deionized water.
On the blending side it was OK, now when I say OK what I mean is I could see but only one person I asked out of 11 could see it so from a customer view it would almost certainly be a pass and on the respray side it was very good but the drying is well up and is must to tak off between coats as it really does pull in dust so wetting the floor and walls if possible is advisable.
just get yourself some axalta water and save half the time
