From paste consistency to route planning to maintenance cycles — here is how professional fly posting campaigns run, step by step, from AGM’s field team.
Fly posting is one of those formats that looks simple from the outside and turns out to have significant operational depth once you start executing it at scale. Apply paste, stick poster, walk away. That is the basic sequence. But the gap between that description and a campaign that actually holds up through a two-week run, covers its target area at the right density, generates good documentation, and delivers consistent results across multiple markets is where most campaigns either succeed or fail.
At American Guerrilla Marketing, we have built a field operation across New York, Los Angeles, Chicago, Miami, Austin, and other major US markets over more than ten years. Every campaign we run generates lessons that go back into how we train crews, select surfaces, mix paste, plan routes, and document results. This guide is a distillation of that accumulated operational knowledge: what makes professional fly posting work, step by step, from brief to campaign close.
Every fly posting campaign starts with a brief. The brief is the document that translates a client’s campaign objectives into specific operational instructions. A good brief makes everything downstream faster and more accurate. A vague brief produces a campaign that has to improvise on the ground, which increases the likelihood of problems.
Before any print run is confirmed, we review the artwork for outdoor legibility. This is not an aesthetic review — we are not redesigning the artwork. We are checking whether the design will communicate effectively from a moving distance on a street-level surface in variable lighting conditions. The issues we flag most often are: type too small to read at walking speed, contrast too low against likely background surfaces, and information hierarchy too complex for the format.
If artwork has legibility issues, flagging them before print saves a client from running a campaign on posters that do not communicate as intended. We prefer to have this conversation before print rather than after posters are up and the issue is visible at street level but no longer fixable within the campaign timeline.
Route selection is the single most consequential planning decision in a fly posting campaign. Which surfaces, in which neighborhoods, on which pedestrian routes determines whether the campaign reaches the right audience and whether the posters hold up through the campaign period.
In our primary markets, we maintain managed posting routes — inventories of specific surfaces with established access arrangements. These routes are developed through relationships with property owners who have given us ongoing access to their exterior walls, hoardings, and outdoor surfaces for campaign postings. Using managed routes gives us reliable, consistent access to surfaces we know are productive, rather than having to identify and scout new surfaces for every campaign.
New markets or campaigns that require coverage beyond our standard routes require surface scouting: walking target neighborhoods to identify productive surfaces, assessing surface quality and access, and confirming that the surfaces we plan to use are appropriate for the campaign. Scouting adds time to the pre-campaign process but is essential for any campaign that needs to run in areas we do not already have established routes.
Not all walls that look like good posting surfaces actually are. Surface quality assessment involves checking:
AGM Field Note: We have rejected surfaces that look great in photos because they have one of these problems. A beautifully visible wall that is covered in loose plaster or is chronically wet from a roof drainage issue is worse than a less visible wall that bonds reliably and holds. The poster you cannot see is always better than the poster that falls off on day two.
Paste is the operational foundation of fly posting. Getting paste wrong — wrong consistency, wrong temperature, wrong preparation method — produces poor adhesion, visible bubbling on the poster surface, and campaigns that start falling off within days of installation. Getting it right is the difference between a poster that holds for three weeks and one that peels in the first rain.
Traditional wheat paste is made from flour and water. The standard preparation method is to mix flour into cold water first — this prevents lumping — then heat the mixture while stirring until it thickens into a smooth, consistent paste. The cooking process activates the starches in the flour, which is what produces the adhesive properties of the final paste.
The ratio of flour to water determines the viscosity of the finished paste. A thinner paste is easier to apply but provides less adhesive body. A thicker paste bonds more aggressively but is harder to brush onto the surface evenly. We mix paste to specific viscosity ranges based on the surface type: thicker for porous surfaces, thinner for smooth ones.
Some paste formulations include additives that improve specific performance characteristics:
Paste application is affected by temperature. Below about 40 degrees Fahrenheit, paste thickens significantly and becomes harder to apply evenly. Above 90 degrees Fahrenheit, paste dries very quickly on the surface before the poster can be positioned and pressed, which creates adhesion gaps. Our crews adjust mixing and application technique for temperature conditions at the time of posting, not just for the surface type.
The physical application of a fly-posted piece follows a specific sequence. Deviations from this sequence typically produce visible quality issues: lifting edges, air bubbles under the poster, uneven adhesion at corners, or paste runs on the surface.
AGM Field Note: The top paste coat step is the one most often skipped by inexperienced crews working quickly. It is also the step that most dramatically affects how long a poster holds. A poster applied without a top coat sealing the edges will begin to peel at the corners within 24 to 48 hours in any wind or rain. With a properly applied top coat, the same poster will hold significantly longer on the same surface. Never skip the top coat.
Large-format fly posting requires assembling multiple printed sheets into a continuous image. This is more complex than single-sheet posting and requires crew members who are trained specifically for the additional precision it requires.
Multi-sheet panels are printed with alignment marks or bleed zones that allow each sheet to be positioned relative to its neighbors. The first sheet is placed as the reference; subsequent sheets are aligned to it. Working from top to bottom and left to right (or the reverse, depending on the wall and the working conditions) produces the most controlled alignment results.
The paste sequence for multi-sheet panels is the same as for single sheets, applied section by section as each panel is placed. Working quickly matters for multi-sheet assembly because the first sheets start to bond to the surface while subsequent ones are being positioned, and adjustments become harder as the paste cures.
Sheet seams in a multi-panel installation should be as tight as possible — not overlapped. Overlapping sheets creates a visible ridge at the seam and a difference in texture between the overlapping and non-overlapping areas that is visible from a distance. Properly butted seams create a nearly seamless image across the full panel width when the artwork is designed to account for the seam locations.
Route execution is the process of moving through the planned posting route and placing posters at each designated surface. For a managed campaign with 50 to 150 placements, this typically involves one to three crew members working together, with a vehicle carrying paste, posters, and application equipment.
Standard fly posting crew equipment includes:
For most campaigns, posting is done in the early morning hours before peak pedestrian traffic. This is partly practical — crews can work more efficiently when foot traffic is lower — and partly strategic: posters placed before the morning commute are seen by the full day’s traffic from the moment people start moving through the neighborhood, rather than being visible only to those who pass after mid-morning posting completion.
Some campaigns require specific timing for strategic reasons: posting the day before a release, posting to coincide with a specific event, or posting across multiple markets simultaneously to create a coordinated moment. We schedule crews specifically for the timing requirements of each campaign rather than defaulting to a standard schedule.
Maintenance is what keeps a fly posting campaign alive beyond day one. Without maintenance cycles, a campaign that starts at 100 pieces in good condition will be down to 40 to 60 viable pieces by the end of week two, as posters are covered by subsequent campaigns, damaged by weather, or removed from surfaces. Maintenance visits restore coverage to target levels.
Maintenance frequency depends on the competitive environment of the specific neighborhoods and the campaign duration. In highly active posting areas — neighborhoods like Williamsburg in Brooklyn or the Fairfax corridor in Los Angeles, where multiple campaigns run simultaneously — maintenance every four to seven days is often necessary to maintain coverage. In lower-activity neighborhoods, weekly maintenance may be sufficient for a standard two to three week campaign run.
We include maintenance cycles in all standard campaign packages. The number of maintenance visits is determined at the planning stage based on the campaign duration, the activity level of the target neighborhoods, and the campaign’s volume requirements.
Every fly posting campaign we run generates documentation at every stage. Geo-tagged placement photos from every location, taken at the time of installation and at each maintenance visit, form the primary documentation record. These photos are compiled into a campaign report that gives clients a complete visual and geographic record of the campaign’s execution.
We provide documentation after each posting cycle — initial install and each maintenance visit — with a consolidated final report at campaign close. For multi-market campaigns, documentation from all markets is consolidated into a single report so clients have a complete view of the campaign’s geographic execution without having to compile reports from multiple vendors.
Our installation pricing for professional fly posting campaigns on managed US routes:

Most campaign problems we see come from a short list of recurring issues. Knowing what they are makes them avoidable.
| Mistake | What It Produces | How to Avoid It |
|---|---|---|
| Skipping the top paste coat | Corners peel within 48 hours; campaign looks ragged by day three | Train crews on the full application sequence; inspect work in the field |
| Wrong paste consistency for the surface | Poor adhesion, bubbling, rapid failure on specific surface types | Scout surfaces before the campaign; mix paste to surface-specific specifications |
| Insufficient volume | Campaign feels scattered, not dominant; target audience sees the poster once, not repeatedly | Plan volume in relation to neighborhood size and campaign duration, not just as an absolute number |
| No maintenance cycles | Coverage drops significantly after the first week; campaign fades before the end of its planned run | Include maintenance cycles in the campaign plan from the start, not as an afterthought |
| Artwork not reviewed for outdoor legibility | Posters go up but do not communicate at street level; campaign investment does not produce the intended awareness | Review artwork for outdoor legibility before confirming the print run |
Fly posting involves applying wheat paste or adhesive to an outdoor surface, placing a printed paper poster against the wet paste, then applying a second coat of paste over the top to seal it. Professional campaigns plan routes across specific neighborhoods, execute placement with trained crews, and maintain coverage with scheduled maintenance visits.
Traditional fly posting uses wheat paste, made from flour and water cooked together until smooth. The consistency is adjusted based on the surface type and weather conditions. Modern campaigns sometimes use commercial adhesive compounds for stronger bonds on specific surface types.
Location selection combines foot traffic density, audience demographic alignment, surface quality, and access to the surface. The best fly posting locations are on routes that the target audience walks regularly, not just the highest-traffic spots in the market.
A professional fly posting campaign can typically be set up and posting can begin within 48-72 hours of receiving final artwork, assuming print is available. Lead time for the full campaign including print production is typically one to two weeks for single-market campaigns, four to six weeks for multi-city campaigns.
Construction hoardings, exterior walls of vacant buildings, smooth masonry, and scaffolding panels are among the best fly posting surfaces. Smooth, clean surfaces with good porosity accept paste best. Irregular or highly porous surfaces require paste adjusted for the specific absorption characteristics of that surface.
Poster campaigns are priced by package and market. Standard poster campaigns (24×36) start at $4,500 for 100 posters (two-week run) and $5,500 for 200 posters. Large format (48×72) campaigns start at $10,500 for 100 posters and $13,500 for 200. An optional two-week maintenance extension is $3,500.

A maintenance cycle is a scheduled return visit to the posting route during the campaign period. Crew members replace posters that have been covered by subsequent campaigns, damaged by weather, or removed. Maintenance is essential for sustaining campaign coverage beyond the initial posting day.
Professional fly posting campaigns are documented with geo-tagged placement photos from every location on the route. AGM provides these photos alongside maps of the geographic distribution of placements and a placement summary after each posting cycle.
Fly posting artwork should be high contrast, with the primary message readable at walking speed from at least three to five meters. Type should be set larger than feels comfortable on screen. Minimal color complexity and a single clear visual hierarchy produce the best street legibility.
