How to Choose the Right Tarp for Holiday Inflatables

Holiday inflatables bring joy — but their blowers, cords and fabric are vulnerable to water and UV exposure. When shopping for a tarp to protect electric inflatables, focus on material thickness (measured in mils), reinforcement and grommet placement, waterproofing vs water resistance, and size/fit. Polyethylene (PE) tarps are the most common choice because they’re lightweight, waterproof when well made, and often UV-treated. For occasional rain protection around cords and blowers, a 5-mil tarp can be adequate and is easy to handle. For windy locations, heavy snow, or abrasive contact (stakes, rough siding), step up to a 12-mil tarp — it resists punctures and stretches far less under load.

Look for reinforced hems with sewn-in poly rope and aluminum grommets; these features make secure anchoring possible and reduce tear risk at attachment points. Grommet spacing matters: 18" spacing (common on heavy-duty models) lets you tie down multiple points around odd-shaped displays; 3-foot spacing (seen on lighter tarps) is fine for simpler covers. UV treatment helps prevent brittle breakdown over repeated seasonal use. Beware of inconsistent thickness or weak seams — customer feedback often flags these as failure points. Finally, choose a finished size that covers the inflatable plus a few feet of ground perimeter to keep cords elevated and prevent splash back.

Protecting Electric Cords

Keeping cords dry is as important as covering the inflatable. Elevate cords on small blocks or a PVC conduit to keep plugs off wet ground. Run exterior cords through a short section of hose or use weatherproof cord covers and waterproof junction boxes if you must expose connections. Don’t seal inflatables airtight under a tarp; provide airflow near the blower to prevent overheating. When using a tarp, drape it so water sheds away from the plug end and avoid pooling; consider adding a simple canopy or angled support to force runoff.

Budget Tiers

Budget (5-mil): Light, affordable, easy to store — good for short-term seasonal use in mild conditions. Mid-range (5-mil larger sizes or reinforced hems): Better finishes and sewn reinforcement for frequent use. Premium (12-mil): Heavier, more puncture- and snow-resistant — recommended where abrasion, wind, or wet snow are likely. Match tier to local weather and how often you’ll set up displays.
