How to prep a commercial building

How to Prep a Commercial Building

When painting any surface at Paint Blue we concentrate on the prep as our top priority. When correctly prepared, a paint job in Tampa area can last for many years without issues. Unfortunately, if it is done incorrectly even the best paint can peal right off weeks after the job is completed.  

Thorough Power Washing:


Paint Blue takes pride in power washing by using commercial grade pressure washers, we can run them at their maximum capacity reaching every section thoroughly washing down all surfaces from the top to the bottom. Furthermore, we analyze the surfaces for mold and or mildew. If detected, we will rinse the surface with Simple Green cleaning solution to kill the mildew growth and to deeply remove any dirt left.

Scraping off commercial paint

Aggressive Scraping:


We will look for all loose areas of paint. These are typically old paint bubbles and flacking paint that we were able to further expose with the first step. It is important to manually scrape them back to a sound surface and to a solid edge.

This step is done to prevent “flagging” a trade term we use when a layer of paint is pealed up in the air flapping in the wind like a flag.
  • Sealing/priming: A full body primer is used on new concrete, wood or stucco that has not been previously painted. For typical repaints we use a sealer/surface conditioner. This coat will lock down any chalky surfaces and create a bond between the original paint and the new topcoat.
  • Patching: It is also crucial to review the building for holes, cracks, and failed caulking. We use elastomeric patch on most hairline cracks and small holes. It is important to prime the building first before applying the patching product as this will give it something solid to bond to. At this phase we will review the caulking around windows, doors, and expansion joints. We typically re-caulk as needed all lightly cracked caulking. This depends on the scope of work agreed upon, we can also go a little deeper removing and replacing completely.
  • Painting: Always work with an expert paint manufacturer representative. They will provide a detailed specification report for each building. Typically, the topcoat will be applied with an airless sprayer and then back rolled for optimum penetration and coverage. Depending on the color a second topcoat will be needed for ideal color coverage.
