Outdoor: Mod Podge decoupage glue and sealer that takes weather

Mod Podge decoupage glue and sealer for projects that live outside — pots, signs, planters and anything that meets rain.

Planters, garden markers, porch signs and anything else that takes weather. These formulas are highly water resistant once cured — rain runs off rather than soaking in — and they hold their colour through a season of sun.

Water resistant is not waterproof and we will not pretend otherwise. For something that actually sits in water, finish over the top with a clear acrylic sealer.

Mod Podge decoupage glue and sealer for outdoor projects

Planters, garden markers, porch signs, mailboxes and anything else that takes weather. These formulas cure into a highly water resistant film: rain beads and runs off rather than soaking into the paper underneath, and the colour holds through a season of direct sun instead of fading to pastel.

We say water resistant and not waterproof on purpose. Nothing we bottle is waterproof. A sealed terra cotta pot will take rain on the outside for years; the same pot filled with wet soil and watered from the top every day is a different test, and for that we seal the inside with a clear acrylic spray as well.

Prepare the surface before you start. Terra cotta needs to be clean and bone dry, bare wood wants a light sanding, and painted furniture should be dust free. Outdoor pieces fail at the join between the surface and the first coat far more often than they fail in the weather.

Outdoor projects we make with these:

  • terra cotta and ceramic planters, inside and out
  • painted garden markers and plant labels
  • wooden porch signs and house numbers
  • upcycling old furniture for a covered patio
  • decorated watering cans and galvanised buckets

Questions we get about this shelf

Will rain wash this off?

No. Once cured it is highly water resistant and rain runs off it. Standing water is the thing to avoid: do not leave a decoupaged piece sitting in a puddle or a saucer.

Do I need a spray sealer over the top?

For anything that holds water, yes. We finish the inside of planters and the underside of anything that sits on wet ground with a clear acrylic spray.

How long before I can put it outside?

Let it dry indoors for at least 72 hours, and longer if the room is cool or damp. Putting a piece out into weather before the film has hardened is the quickest way to lose it.
