The two most common methods for mixing Matthews paint products are a Mixing Cup or a Mixing Stick:
Using a Matthews Mixing Cup
Thoroughly agitate the paint or stir the mixed color.
Locate the “3:1:1” measurement ratio grid printed on the cup.
In the “3:1:1” ratio grid, choose the number that represents the volume of paint you need. We will use “4” in our example. (See Figure 1)
Pour the paint into the cup up to the “4” in the left column.
Pour the catalyst into the cup up to the “4” in the middle column.
Pour the reducer into the cup up to the “4” in the right column.
Optional: Add accelerator (using separate accelerator cup) to the specific volume indicated on the product’s Technical Data Sheet (TDS).
Stir the properly measured mixture for 60 seconds or until you can visually see that all ingredients are thoroughly mixed.
Figure 1
Left column (yellow) = Paint
Middle column (red) = Catalyst
Right column (blue) = Reducer
Using a Matthews Mixing Stick
Important!
A mixing stick is designed to be used in a straight-sided container.
Never measure paint with a mixing stick in a tapered mixing cup.
Thoroughly agitate the paint or stir the mixed color.
Place a Matthews mixing stick into a straight-sided container so that it stands vertically.
Choose one of the four columns (on either side) based on the total ready to spray quantity desired. In this example we are using the left column with the largest increments. (See Figure 2) Note: When using a Mixing Stick, all ingredients are measured in one vertical column.
Pour the paint into the cup up to the “3” in the left column.
Pour the catalyst into the cup up to the “4” in the same column.
Pour the reducer into the cup up to the “5” in the same column.
Optional: Add accelerator (using separate accelerator cup) to the specific volume indicated on the corresponding product’s Technical Data Sheet (TDS).
Stir the properly measured mixture for 60 seconds or until you can visually see that all ingredients are thoroughly mixed.

Theming
Let’s Make Rust
Important!
To make rust you have to know what it looks like.
Steel: Dark Brown/Brown/Red
Iron: Dark Orange/Orange/Brown
Aluminum/Oxidation: White/Yellow
Tools Needed:
Multiple Sponges/Sizes
Rags
Stiff Acid Brushes
Soft China Bristle Brush
First, decide what type of rust you want to emulate.
Paint your base color. For best results, let it set overnight.
Always scuff before you start the theming process with a Scotch-Brite pad for good adhesion.
Clean with 6410SP/01 Low VOC PreCleaner.
Pick your first color to make your rust. It is usually the darkest color.
Let the first color of rust dry, then add clearcoat to ensure next colors don’t smudge.
If clearcoat has sat longer than 24 hours, scuff between coats. Then clean. Pick your second color to make your rust. It is usually the medium color.
Let the second color of rust dry, then add clearcoat to ensure next color doesn’t smudge.
If clearcoat has sat longer than 24 hours, scuff between coats. Then clean.
Pick your third color to make your rust. It is usually the lightest color, and is used minimally.
When painting the final clearcoat, you can use multiple gloss levels to imply the aging process.
Always refer back to substrate guide for additional information.
Aging
Let’s Make It Look Old
Important!
To show more age, you can add mold and mildew by sponging on different shades of green, or you can add dirt and grime.
To make the aging look more realistic, have the areas that are in the sun faded more, and the areas that are in the shade not as faded and glossier.
Let’s Do a Paint Fade to Show Age
Clean with 6410SP/01 Low VOC PreCleaner.
Prime bare areas if needed.
Paint base color selected.
After base color has been painted and flashed, add a small amount of white or another color such as a light yellow to base to start fade. (Do not add color to already mixed paint in spray cup. That will change the mix ratio).
Add color in original base, then mix 3-1-1.
Start fade from bottom up for a better blend line.
As soon as second color has been blended, spray a coat of clear to burn in fade line. This will keep paint edge smooth.
If third color is desired, add more color to your base, then spray from bottom up as before and re-clear complete area.
To show additional age, you can clear first base color in a semi-gloss, then fade to a satin, and then to a matte finish.
Always refer back to substrate guide for additional information.
Should be urethane-compatible foam, velour, woven polyester, mohair, or lambs wool.
Other rollers may swell or dissolve.
Examples:
4” Whizz rollers: #34011 (yellow), #54011 (white with yellow/black stripe), #54060 (black), or #74011 (white with blue stripe)
4-1/2” Wooster rollers: #RR304 (white), #RR310 (green), or #RR311 (red)
Brushes:
Use a china bristle or fine bristle nylon/polyester brush.
Cleaning and Preparation
Cleaning:
Apply a generous amount of cleaner on the surface with a clean cloth or a hand held spray bottle and wipe the surface.
The initial application will float contaminants to the surface, and the second wipe using a separate clean dry cloth, will remove contaminants.
Wipe the surface dry while it is still wet, using a clean white cloth in one direction. This will eliminate the smearing of contaminants. Be sure to change rags frequently.
Never let the cleaner dry on the surface.
For best results, clean surface before and after sanding.
Sanding:
Abrade as necessary with 180-320 grit, finishing sanding with the finest grit possible.
Be sure to featheredge the original finish surrounding the repair area.
Priming Bare Metal or Repaired Areas
Primer Product Selection
Select an MPC Primer that will provide the fill characteristics, dry times and VOC level desired and meet all state and local regulations. Always refer to MPC Technical Data Sheets for all performance data and VOC.
Notes:
Avoid overloading the roller or brush.
Apply coats as evenly as possible. Heavy coats will increase flash times and dry times.
Even coats will provide better coverage and uniformity than heavy coats.
Use appropriate reducer for product being used. Refer to the Matthews Product Data Sheet for mix recommendations for optimal performance.
Maintain 50% overlap to avoid lap marks.
Primer Rolling Process (spot repair):
Roll 1st Coat:
Start from the center of the repair and roll the primer over the entire repair area using a “flicking” or lifting technique to create a soft edge all around the repair area. This technique will ensure a thin, smooth edge and make sanding easier.
Allow the 1st coat to flash off until it is dry to touch.
Roll 2nd Coat:
Using the same application technique apply the 2nd coat just beyond the 1st coat to ensure a soft edge.
Primer Rolling Process (full panel):
Roll 1st coat edge to edge.
Allow to flash until surface is dry to touch.
Roll 2nd coat edge to edge.
Allow to flash until surface is dry to touch.
Important: If primer is left to dry longer than 24 hours, surface must be lightly sanded with 320 grit or red scuff pad before applying topcoat.
Topcoat Rolling Process (solid colors only):
Mix topcoat being used according to recommendations on TDS.
Roll 1st coat.
Allow to flash until surface is dry to touch.
Roll 2nd coat.
Refer to product TDS for dry time recommendations.
