Steps to Success

Matthews Paint Substrate Preparation Recommendations

Step #1 — Matthews is for Professional Use Only.

Step #2 — Always follow proper safety precautions when using Matthews products.
Safe usage requires reading, understanding and following all labels, SDS, and other product literature before use.

Step #3 — The spray area and substrate must be warm and have adequate airflow.
Application of primers, topcoats, and clearcoats should never take place in temperatures under 60°F/16°C. Substrates should also be brought to or above this temperature guideline before applying any primer or topcoat.

Step #4 — Properly clean substrate.
Professionals don’t even think about priming or painting over any substrate that hasn’t been properly cleaned and prepared. Use proper cleaning products and procedures.

Step #5 — Knock down sharp edges whether routed or cut. Round any dramatic sharp edges on substrate. Primer and paint topcoat films are weakest on sharp 90 degree edges.

Step #6 — Use the right primer for every specific substrate.
Always use the appropriate primer and application techniques suggested from the Matthews substrate guide.

Step #7 — “When in doubt, test it out.”
We recommend testing the process for any new product, primer, or first time application procedures before permanent production begins. Remember that the change of seasons affect the temperature and humidity during application, so periodic testing on application and adhesion confirms the product and production performance.

Step #8 — Choose the proper reducer for each application.
Review product data sheet for reducer temperature guidance.

Step #9 — Allow specified times between coats. For both primers, topcoats, and clears, extend flash times between each coat application.

Step #10 — Contact Matthews Paint with any questions. Matthews’ customer service and technical assistance are both available for any color formula match, specification, or technical question that may arise.

Important Notes

Before any spray applications, consult your local city, local air quality districts, or government office to determine what regulations you must follow to be compliant with VOC regulations in your community. 45 330SP Speed Prep Cleaner may not be used in certain areas of the country!

Investigate or consult with the substrate manufacturer for information regarding proper cleaning and preparation for specialty coatings. If you cannot find your substrate in this guide, contact the substrate manufacturer.

We recommend to periodically test adhesion on a sample of the substrate you are utilizing to ensure application process in your environment. Perform this test after a full cure of product has been applied (72 hours or more). A Cross-Hatch Adhesion test is the most common system utilized for this process.

Before opening the products listed, be sure you understand the warning messages on the labels of all components, since the mixture will have the hazards of all its parts. Use product technical data sheets for guidance.

Follow spray equipment manufacturer’s instructions to prevent personal injury or fire.

Always adhere to directions for proper respirator fit, use, and maintenance.

Wear eye and skin protection at all times when working in the spray area.

Observe all application precautions.

EZ Spray

Process for Field Repair
Preparation, Priming and Painting

This is a suggested sample process only. As every field repair will be different, it is up to the technician to determine the correct process for each repair. This sample is designed for panel repair painting only. SPOT REPAIRS ARE NOT RECOMMENDED. Please refer to the Matthews Paint Substrate Preparation Guide for the proper undercoat selection. All flash, tack, dry and cure times will be greatly affected by increases and decreases in temperature and humidity. Always refer to the correct MPC Technical Data Sheet for each product being used in your process.

EZ Spray is For Professional Use Only. It is not for household use.

This product is not intended for use within the state of California under CARB’s Regulation for Reducing Volatile Organic Compound Emissions from Aerosol Coating Products.

Safety

Always protect yourself and the environment

  1. Wear proper protective gloves, clothing, eye and respiratory protection while filling, activating and applying any EZ Spray products.
  2. Follow all federal, state and local laws for personal protection and environmental regulations.
  3. Refer to Matthews Paint Technical Data Sheets and Safety Data Sheets.

Cleaning and Preparation

Wipe repair with 6405SP LOW VOC Cleaner. Refer to MPC Products sheet MPC172.

  1. Repair area should be free of moisture, dirt, grease, wax and other contaminants.
  2. 6405SP Cleaner should be applied with the ‘two rag’ system. One cloth should be saturated with cleaner and wipe a small section at a time. The second cloth to wipe away the cleaner while it is still wet on the surface.
  3. 6405SP Cleaner may also be applied using a SureShot or small handheld sprayer then wipe with clean cloth until dry.
  4. Do not allow 6405SP cleaner to dry on surface.
  5. Repeat this process until the area is clean after wiping the surface.
  6. The use of lacquer thinners, enamel reducers or other solvents as cleaners is not recommended.

Sand repair area to be painted

  1. Prep all areas to be painted as necessary.
  2. Scuff sand with as fine a grit sandpaper as possible.
  3. Fine sandpaper, Scotch Brite or the like may be used.

Final wipe

  1. Remove sanding dust with compressed air if available or tack cloth.
  2. Clean again with 6405SP LOW VOC Cleaner as described above.

Priming (Epoxy Primers Recommended)

Refer to the Matthews Paint Substrate Preparation Guide for selection of the proper undercoat for your particular repair. Always read the Technical Data Sheet for the undercoat being used.

  1. Mix primer by volume.
  2. Use MPC mixing sticks or MPC mixing cups for proper ratios.
  3. No induction time required.
  4. Use either the 3.5 VOC White or Black Epoxy Primer, 3.5 VOC Gray Epoxy Primer, 2.1 VOC Gray Epoxy Primer or LVU 100 Ultra Low VOC Primer.

Roll primer on using a smooth foam roller. Apply 1st coat.

  1. Foam or velour rollers must be approved for urethane finishes.
  2. Apply coat as evenly as possible.
  3. Even coats will give better coverage than heavy coats.

Let flash between coats. Apply the last coat.

  1. Allow 10-15 minutes.
  2. Finish will become more ‘tacky’ during flash time.
  3. Apply 2nd coat as evenly as possible.

Once the Epoxy Primer and the hardener are mixed together, the pot life will vary by product and temperature.

  1. Pot Life. The amount of time the mixed components are usable.
  2. When nearing the end of a product’s pot life, product will become thicker than normal.

Dry Time

  1. Allow Epoxy Primer dry for a minimum of 1 hour at 70 degrees before applying topcoat color.
    An overnight dry is recommended before sanding if required. After 24 hours sanding is required before applying topcoat.

Sand primed repair area to be painted (if required)

  1. Sandpaper, Scotch Brite or the like may be used. 320 or finer.
  2. Areas surrounding the primer should be scuffed in order to taper the repair.
  3. Pay particular attention to small crevasses and edges.
