What are common paint defects? How do you minimize them?

ILRegatta_MagellanSelecting the proper architectural paint for a project’s architectural aluminum products can ensure a visually pleasing result for years to come. Even when the correct painted coating is chosen, other factors can cause unforeseen defects to the aluminum product’s surface. Here are some common flaws that may occur, and how to correct or avoid them.

Pretreat the Metal, Dry Thoroughly

The condition of the surface to be coated plays a big role in the final product. The presence of oil, grease or other contaminants can cause adhesion failure in the paint. This could result in the topcoat peeling or flaking off. The rolling process of tubes and extrusions also can leave such a residue. For architectural finishes applied at a paint facility, baking of the paint after application is required, any reside not removed prior to painting, may run, or leach out, from beneath the coating, damaging both the paint and metal.

Your finishing applicator can avoid these flaws by pretreating the metal before paint ever touches it. Using a combination of high-power water rinses, high-temperature acid clean, etch and desmut and a chromium phosphate coating will remove most contaminants and increase the corrosion-resistance of the aluminum. A thorough drying process afterward will ensure that any remaining moisture is evaporated and that the finishers have an ideal surface on which to work.

Know Your Oil

Non-water soluble oils can lead to “fisheye” problems. Fisheye is a defect where circular depressions or “craters” appears in the finish. Most pretreatment systems are not equipped to remove these oils in advance, so if you suspect them to be present on your surface, be sure to discuss this with your finisher.

Watch for Corrosion

If the metal was stored outside before painting, it may suffer from corrosion in spots, which will stain in areas after being finished. Corrosion can be minimized or removed entirely by sanding the affected areas of the metal prior to finishing.

The process of paint application also can cause defects to appear later. Blisters or “pops” can appear beneath the surface of the finish after the curing process is complete, if there wasn’t enough flash off time before baking. Inconsistent coloring can occur in the paint if its application was inconsistent or the thickness of the finish varies across the surface. This will result in a coat that has color variation throughout, particularly if viewed from different angles.

These flaws can be avoided by quality-controlled, standard operating procedures for paint application on the part of the finishers. By applying the coating consistently throughout the process, the finishers can ensure less variation in the end product. A combination of automated spray equipment and painting specialists, helps to ensures an even, gradual coating application to prevent film build-up.

Send a Sample

If you are still concerned about the opportunity for defects in your architectural paint, consider sending a sample sheet of the metal that will be used to your finisher, as a mock-up, in advance. By applying the exact process that would be use for your actual project, any potential flaws can be identified and corrected in advance.

Building Enclosure features “Preventing coating failures”

Helping ensure the best finish for architectural aluminum products, Linetec’s Tammy Schroeder recently authored “Preventing coating failures.” Published in the July issue of Building Enclosure magazine, the article addresses the benefits and cautions of selecting paint and anodize finishes.

5-webWith proper consideration and application, finished architectural aluminum will retain its intended look and long life with minimal maintenance. A durable finish helps provide the desired performance in the harshest environments, including the highly corrosive seacoast. These qualities reduce the need to replace materials and components, conserve resources, optimize labor and save money.

Anodize Nickel Test

Nickel Test

When extreme hardness is required for aluminum building components, such as in high-traffic areas, like entranceways and railings, an AAMA 611-14 anodized aluminum finish should be specified.

The hardness of anodized aluminum rivals that of the diamond.

This “Nickel Test” demonstrates why a Class I high-performance anodize coating is the perfect choice for exterior architectural applications.

Each year brings new firsts, this year we had a First Time Golfer! Fabio from PPG (originally from Brazil) had never been on a golf course before. Their team didn’t win, but they assured us they had a great time.

 

Not only do our guests get to golf at our outing, but they also have the chance to answer trivia questions, find hidden items throughout the course, try for the best poker hand and play crazy games! Two of the games this year were Birdie Bounce…..

Linetec People to Know: Cara Bahlow

CaraB-(2)-webQ:  Tell me about your job

A:  I am the Quality Engineer for the paint facility. This year, I will celebrate my 10-year anniversary with Linetec.  My responsibilities include supervising the Quality Assurance department, reviewing customer specifications and working with customers to understand their quality expectations, managing customer concerns and returns, corrective actions, maintaining certifications, and providing requests for documentation such as test reports and certificates of analysis.  I relay customers’ needs internally to ensure that we are providing the quality finish that our customers are expecting.

Q: What did you do prior to Linetec?

A: Prior to Linetec I worked in Milwaukee, Wisconsin, for a global adhesive corporation specializing in the distribution of specialty chemicals and equipment. I spent eight years as the Quality Manager for two divisions that offered custom packaging for a variety of materials and developed custom-formulated products.  I enjoyed my job thoroughly, but was excited for the opportunity to return to Wausau with my young family so we could spend a lot of time with our extended family. Linetec was the perfect fit!  Often people tease me that I went from watching glue dry to watching paint dry!

Q: What is your favorite part of your job?

A:  My favorite part of my job, as well as the biggest challenge of my job, is the fast paced nature of the production environment.  In quality you can never have a plan for the day because you do not know what challenges the day will bring.  I really like visiting customers and working through customer audits to understand how they use our services and what end application their product has.  I also like helping and watching employees grow into experienced, confident employees who are proud of their work and what Linetec has to offer.

Q: What is the biggest change you’ve seen over the years of doing your job?

A:  The biggest change I’ve seen in my job is the evolvement of Linetec’s quality program and that of our customers.  Many of our customers use instrumentation in their receiving and quality inspection.  Our employees, the data we maintain, and the testing and procedures that we have in place have advanced significantly over the years.  Customer requests that once seemed an impossibility have now become standard procedure.  I am proud of what we’ve accomplished; the Linetec team has never been stronger!

Q:  What is something you are looking forward to?

A:  At Linetec I look forward to the growth our new product offerings.  There are some very exciting finishes I can’t wait to see more of on our paint line!  Personally, I look forward to family vacations and every moment spent together making memories as a family.

CaraB-(3)-webQ:  What do you enjoy doing outside of work?

A:  Outside of work, my husband and I enjoy cheering our 14-year-old son and 11-year-old daughter on in their activities – whether it is on a football field, dance studio or one of their many Scouting adventures.  I’ve been a Girl Scout leader and a Sunday School teacher for many years. I love seeing that look on a child’s face when they’ve learned something new or mastered a new skill.  I hope I’ve influenced them positively and someday they’ll remember these moments with a smile.  I love singing for our church and participating in the church choir.  I enjoy swimming, figure skating and playing tennis.  My favorite place to be is our family cabin in Tomahawk, Wisconsin – boating, fishing, swimming, campfires and ice cream.  It has been a very special part of my life since I was a young child.  There is no place that I would rather be!
