What is the Best Application Equipment?

Wednesday, April 17th, 2013

So now you have the product with which you plan to coat your roof. How should I apply those coatings and what equipment will I need?

In this blog, we will talk about the different equipment you can use, and where they are most applicable.

Brief summary:

  • Brushing is suitable for small areas, edges or corners.
  • Rollers are useful on larger and relatively flat surfaces.
  • Spraying is best for large areas, but also works very well on irregular shapes.

Brushing is slower than other methods of paint or coating application. So you would mainly use brushes for small areas and cutting in corners or edges. Generally you want to use a good synthetic bristle brush.

Rollers are great for use of large and flat areas. They don’t require as much skill as spraying. Rollers are not as effective in applying paint evenly. You have to be careful with application using a roller you can produce unintentional roller marker or a “stipple” effect. Generally for latex paints such as Acrymax you should use synthetic fiber covers.

Airless spray is great for covering large areas but requires more skill to use. When you use airless spray you need to first choose the tip you will be using. For more information on what is required in choosing the spray tip click here. While spraying you typically want to hold the sprayer so the tip is 10-12 inches from the surface. The secret to good spray painting is to apply even coats.

You may need to use more than one method to complete your job. Make sure you use the correct equipment for the best results.

Spring is on the Way: Prepare for Coating

Monday, March 4th, 2013

We’re getting closer; only 17 days now until spring! In our last blog we talked about Roof System Selection. This week we want to focus on preparation. Preparation is one of the most important and critical steps for successful and long lasting roof coating applications.

You must make sure the preparation of the roof is done correctly to get the best results for a long lasting roof. First step in the preparation is removing all the dirt, debris, oils, and contaminants from the roof. This can be done by the following methods:

  • High Pressure washing
  • Vacuuming/Air-blowing
  • Mechanical cleaning

Beyond your standard contaminants (dirt, debris, etc.), your project may have contaminants that require more rigorous methods to remove.  Corrosion needs to be well prepared and may require wire brushing or other aggressive methods. Biological growth may require chemical cleaning additives. Certain surfaces like EPDM are generally wash-primed with products like Acrymax PR-101 in order to accept coatings.

Preparation is a crucial step in any coating system process and should be evaluated. This can be done with a tape test which involves applying masking tape to the surface, and then peeling off the tape. If there are contaminates on the tape that will interfere with adhesion of the coating, further cleaning or use of a primer are necessary. A primer is NOT a substitute for good preparation.

Acrymax Technical Bulletin ATB-103 describes preparation methods and how to evaluate the effectiveness of the preparation method used.
