For commercial property owners in Papillion, NE, protecting a flat roof is a major investment in building longevity and energy efficiency. One of the fastest-growing solutions in the roofing industry is liquid applied roofing, a system praised for its seamless waterproofing and cost-effectiveness. However, many do not realize that the true success of a liquid applied project depends less on the coating itself and more on the surface preparation that comes before application. Without proper preparation, even the best product will fail. To ensure your building’s roof is managed correctly, reach out to A.G. Roof Coatings at 402-578-4408.
Liquid Applied Roofing Fundamentals
Surface Preparation Matters
Liquid applied roofing is designed to bond directly to the roof substrate, forming a seamless protective barrier. However, adhesion is only possible when the surface is clean, dry, and properly primed. Skipping or rushing preparation leads to poor bonding, blistering, peeling, and premature coating failure.
Key preparation steps include:
Cleaning the surface – removing dirt, dust, oil, and loose debris.
Repairing damaged areas – addressing cracks, splits, or saturated insulation before coating.
Drying the substrate – ensuring no moisture is trapped, which could cause bubbling later.
Priming – using manufacturer-approved primers to create an adhesive-friendly surface.
When done correctly, preparation ensures the coating performs to its full potential and extends the life of the roof system.
Common Preparation Mistakes
While surface prep sounds straightforward, many issues arise when it is not done thoroughly. Commercial building owners should be aware of these common mistakes:
Incomplete cleaning – Residual grease, dust, or organic growth like algae prevents adhesion.
Skipping moisture checks – Trapped water in the substrate leads to bubbling or coating delamination.
Ignoring minor repairs – Small cracks or punctures left untreated can worsen under the coating.
Improper primer use – Each substrate (metal, concrete, single-ply membrane) requires the right primer for optimal bonding.
Each mistake reduces the coating’s ability to provide watertight protection, often resulting in premature failure.
Benefits of Proper Preparation
When preparation is done right, facility managers enjoy several key advantages:
Extended roof lifespan – Well-prepared surfaces allow coatings to last their full service life, sometimes 10–20 years.
Improved energy performance – Seamless coatings reflect UV rays better when applied over smooth, primed substrates.
Reduced maintenance costs – A strong bond means fewer repairs down the road.
Warranty protection – Manufacturers often require documented preparation steps for warranties to remain valid.
Essentially, investing in professional preparation pays off in long-term savings and peace of mind.
Professional vs. DIY Preparation
Some building owners may consider surface prep as a task maintenance staff can handle. While basic cleaning may be possible in-house, full preparation should be left to professionals. Experienced contractors like A.G. Roof Coatings understand manufacturer specifications, moisture testing, and primer selection, all critical to successful adhesion.
DIY attempts often overlook hidden damage or moisture issues, which compromise the entire project. For commercial roofs, where square footage is large and investments are high, professional expertise ensures maximum protection and ROI.

FAQ
How long does surface preparation usually take for a commercial roof?
The timeline depends on roof size and condition, but preparation can take anywhere from one day to several days before coating begins.
What tools are used to prepare a roof for liquid applied coatings?
Common tools include pressure washers, grinders, brooms, moisture meters, and manufacturer-specific primers.
Can liquid applied coatings be installed without primer?
In most cases, primers are essential for adhesion, though some systems are designed as primerless depending on the substrate.
Does preparation add to the project cost?
Yes, but it is a small fraction of the overall cost and ensures the coating performs correctly saving money long term.
