Matthews Paint Substrate Preparation Recommendations

These guidelines are to be used as recommendations only.

Important Notes

Materials described are designed for application by professional, trained personnel using proper equipment and are not intended for sale to the general public.

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.

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.

Products mentioned may be hazardous. Always follow proper safety precautions when using Matthews products. Safe usage requires reading, understanding and following all labels, SDS, and Technical Data Sheets before use.

Procedures for applications mentioned are suggestions only and are not to be construed as representations or warranties as to performance, results, or fitness for any intended use, nor does Matthews Paint warrant freedom from patent infringement in the use of any formula or process set forth herein.

Keys to Success

Statements and methods described are based upon the best information and practices known to Matthews Paint.

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 60ºF/16ºC.

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.

Follow the procedures listed for specific substrate in this guide for cleaning, preparation and primer recommendations.

Follow spray equipment manufacturer’s instructions for gun set-up and proper air pressure recommendations.

We recommend testing the process for any new substrate, product or first time application procedures before permanent production begins. Periodic testing on application and adhesion confirms the product and production performance.

Review Technical Data Sheets or Matthews Reducer Selection Charts for reducer selection guidance. Remember that the change of seasons affect the temperature and humidity during application.

Allow proper flash time between coats. Flash times will vary dependent upon film thickness, temperature, solvent selection, spray gun set-up, application, etc. Additional coats may require extended flash time.
