Every camp parent knows the sunscreen bottle goes to camp. Most label it. Almost none of them add a clear overlay — and by the third week of a month-long session, the label that was perfectly legible at drop-off has faded to the point where the name is barely readable.
It's not a bad label. It's not a preparation problem. It's a chemistry problem. The active ingredients and carrier oils in sunscreen and bug spray are slow-acting solvents for label ink — and every time your child's sunscreen-covered hands pick up the bottle, they're depositing a tiny amount of product directly onto the label surface. Over weeks of daily use, that accumulation works on the ink and adhesive in ways that become visible mid-session.
Clear overlays exist specifically for this problem. This post explains exactly what they are, which bottles need them, how to apply them correctly, and why they're one of the most underused items in a camp labeling kit despite being one of the most useful.
From the founder of Sticky Monkey Labels
I'm Dodie — founder of Sticky Monkey Labels, boy mom of three sons, and 15 years in business since 2011. Clear overlays are the product parents discover after their first camp session — when they see what happened to the sunscreen label. This post explains it before that happens.
What's in this guide
1. Why Sunscreen and Bug Spray Degrade Labels Over Time
A waterproof label on a standard water bottle or food container survives daily dishwasher use for years. The same label on a sunscreen bottle may start showing wear after two or three weeks at camp. Understanding why explains exactly what clear overlays solve.
Sunscreen and insect repellent contain active ingredients — UV filters, DEET, and various carrier oils and emollients — that are formulated to penetrate surfaces and spread evenly. That penetrating, spreading quality is what makes them effective as products. It's also what makes them slow-acting solvents for everything they touch repeatedly, including label ink and adhesive.
The mechanism at camp
- Sunscreen is applied to hands and arms before outdoor activities — multiple times per day
- Product-covered hands pick up the sunscreen bottle, grip it, and set it down repeatedly throughout the day
- Each contact deposits a microscopic amount of product on the label surface
- Over weeks of daily repetition, the cumulative deposit works on the ink layer, causing it to soften, blur, and eventually become difficult to read
- The adhesive bond at the label edges can also be gradually compromised, causing early lifting
On a water bottle that's only ever touched by clean or wet hands, this mechanism doesn't exist. On a sunscreen bottle handled multiple times daily with product-covered hands throughout a full summer camp session, it's significant and predictable.
2. What Clear Overlays Actually Do
A clear overlay is a transparent protective layer — slightly larger than the name label it covers — that applies directly over the top of an applied label. It's a physical barrier between the label surface and whatever touches it.
What the overlay does
- Creates a sealed barrier over the printed name label surface — sunscreen-covered hands contact the overlay, not the ink
- Protects the ink layer from the solvent action of oils and active ingredients in sunscreen and bug spray
- Seals the edges of the name label underneath, giving the adhesive additional protection from edge-lifting caused by chemical exposure
- Is itself waterproof and designed for the same outdoor, high-contact environments as the labels it protects
What it doesn't do
A clear overlay doesn't make a poorly applied label last longer. If the name label underneath hasn't been applied to a properly alcohol-prepped surface with firm pressure and the 24-hour cure time, the overlay won't compensate for a weak initial bond. The overlay protects a well-applied label from chemical degradation — it doesn't substitute for correct application in the first place.
3. Which Bottles Need a Clear Overlay — and Which Don't
Clear overlays are a targeted solution for a specific problem, not a universal requirement for every label. Applying overlays to items that don't need them adds unnecessary time and expense to the labeling session. Understanding which bottles are actually at risk is what makes the decision clear.
| Item | Overlay Needed? | Reason |
|---|---|---|
| Sunscreen bottle | Yes — essential | Handled with product-covered hands multiple times daily throughout the session. Without an overlay, ink degradation begins in the first week of heavy use. |
| Bug spray / insect repellent | Yes — essential | DEET and similar active ingredients are particularly aggressive on label ink. Of all the toiletry items sent to camp, bug spray has the most damaging effect on labels without overlay protection. |
| Products with chemicals or essential oils | Consider an overlay | Any product containing chemicals or essential oils that gets handled with product-covered hands repeatedly may benefit from an overlay on longer sessions. When in doubt, add one — they take seconds to apply. |
| Water bottle | Not needed | Handled with clean or water-wet hands. No oil or active ingredient contact. Standard waterproof label holds for years without overlay. |
| Shampoo / conditioner / body wash | Not needed | Soap-based products don't have the same solvent action on label ink as oil-based products. Standard waterproof labels hold through a full camp session on these bottles without overlay. |
| Food containers and lunchbox | Not needed | Washed nightly, handled with clean hands. No oil exposure. Standard waterproof label is the right choice. |
| Shoe labels | Yes — included | Every shoe label order includes a clear overlay specifically for the heel friction environment. See Section 4. |
4. Clear Overlays for Shoe Labels
Every shoe label order from Sticky Monkey Labels includes a clear overlay — and for shoe labels, the overlay isn't optional. It's a required part of the application.
The inside heel of a shoe is a friction environment, not a chemical exposure environment. The overlay on a shoe label isn't protecting the ink from sunscreen — it's protecting the print surface from the constant physical friction of the heel rubbing against it with every step. Without the overlay, heel friction gradually wears through the ink layer regardless of how well the adhesive bond holds. With the overlay, the clear protective layer takes the friction while the print underneath stays intact.
5. How to Apply a Clear Overlay Correctly
The overlay application follows the same principles as any label application — clean surface, firm pressure, correct positioning. The difference is that it goes over an existing label rather than directly onto a bare surface, which adds one consideration: alignment.
The correct sequence
- Apply the name label first. Clean the surface with alcohol, dry, apply the name label with firm pressure across every edge. The name label goes down before the overlay — not simultaneously.
- Let the name label set for a minute. Don't apply the overlay immediately after pressing the name label. Give the name label a brief moment so it's positioned and not sliding before you apply something on top of it.
- Position the overlay centered over the name label. The overlay is slightly larger than the name label — it should overlap every edge of the name label by a small margin. Center it by eye before pressing. Once you start pressing, it's difficult to reposition.
- Press firmly from center outward. Same technique as the name label — center to edges, thumbnail along every edge for full contact. The overlay is bonding both to the name label surface and to the bottle surface around the name label's perimeter.
- Check all overlay edges. Every edge of the overlay should be flush against the surface. Any lifting overlay edge at this point needs to be pressed back down immediately before it dries.
- Allow 24 hours before first use. The same cure time applies to the overlay as to any label.
6. Common Mistakes With Clear Overlays
Applying the overlay before the name label is positioned
The overlay locks the name label in place. If the name label isn't positioned correctly before the overlay goes on, you can't adjust it afterward. Position and press the name label first. Confirm it's where you want it before applying the overlay on top.
Centering the overlay incorrectly so it extends past the label edge only on one side
An overlay that's offset to one side doesn't seal all edges of the name label underneath. The unsecured edge is the one that will eventually lift from product exposure. Take a moment to center the overlay properly before pressing — the few seconds of alignment saves the label.
Skipping the overlay on bug spray because it seems less important than sunscreen
Bug spray — particularly DEET-based repellents — has a more aggressive effect on label ink than most sunscreens. If anything, the bug spray bottle needs the overlay more urgently than the sunscreen. Label and overlay both, every time.
Using the overlay without alcohol-prepping the original surface first
The overlay bonds partly to the bottle surface around the name label's perimeter. If the bottle surface was never cleaned with alcohol before the name label was applied, the edges of the overlay that sit on bare bottle surface are bonding to an oil-contaminated surface — and will lift over time regardless of the overlay itself. Surface prep before the name label is the foundation for everything that goes on top of it.
Assuming the overlay makes up for a poorly applied name label
If the name label was applied without alcohol prep, without full cure time, or with lifting edges, the overlay doesn't fix those issues. Start with a correctly applied name label. The overlay's job is to protect a good label from chemical exposure — not to rescue a poorly applied one.

Frequently Asked Questions
Do I need overlays for a one-week camp or only for longer sessions?
For a one-week camp, sunscreen and bug spray labels will likely survive the session without an overlay — the cumulative chemical exposure over five days isn't usually enough to cause significant degradation. For two-week sessions and longer, overlays on sunscreen and bug spray are worth the two minutes they add to the labeling session. For a month-long or full-summer camp, they're essential — labels without overlays on these bottles may be illegible by the end of the session.
Can I add a clear overlay to a label that's already been applied?
Yes — as long as the existing label is clean and firmly bonded. Wipe the label surface with a dry cloth to remove any product residue, then apply the overlay over the top using the same press-from-center technique. If the existing label has lifting edges, press those back down firmly before applying the overlay on top. A late-added overlay on a well-bonded label provides the same protection as one applied at the start — the barrier effect works regardless of when it's added.
My child's sunscreen label faded completely last summer. Can I just put a new label and overlay on for this session?
Yes — clean the bottle surface thoroughly with alcohol to remove any product residue, let dry completely, apply a new name label, press firmly across all edges, then immediately apply the clear overlay on top. Allow 24 hours before the bottle goes to camp. The previous label's degradation happened because of product exposure without overlay protection — the same label with an overlay from the start this year will hold for the full session.
Does the clear overlay work on all bottle types — plastic, metal, squeeze bottles?
Yes — the overlay applies to the same surfaces as the name label: smooth hard plastic, stainless steel, and metal. The overlay bonds both to the name label surface and to the bottle surface around the label perimeter, so the bottle surface type matters the same way it does for the name label. Silicone bottles and textured surfaces have the same limitations for overlays as they do for name labels — find the hard plastic component (nipple ring, cap, smooth neck area) and apply both the name label and overlay there.
Should I use an overlay on my child's water bottle?
Not necessary for standard use. Water bottles are handled with clean or water-wet hands — there's no oil or active ingredient exposure that would degrade the label over time. A correctly applied waterproof label on a clean-prepped water bottle lasts for years without an overlay. Save the overlays for sunscreen, bug spray, and shoe labels where the specific exposure conditions justify them.
How many clear overlays do I need for a camp session?
Count the bottles that need them: one for the sunscreen body, one for the sunscreen lid, one for the bug spray body, one for the bug spray lid, and one or two for any other oil-based product bottles you're sending. Shoe labels — one per shoe, both shoes of every pair going to camp — are included with your shoe label order. A typical camp kit uses 6–10 overlays total across all the items that need them. Order a few extras in case of application errors — overlays that go down crooked can't be repositioned without a fresh one.
