A Reading by CallumOutdoor & Water-Repellent Cushions
A coral striped outdoor bench cushion under the jug
A glass jug, a striped cushion, teak slats. Ten seconds of water tell you more than a page of promises, and so does knowing which parts of a cushion the weather actually reaches.
The quick answer
On an outdoor bench cushion, spend on outdoor-rated fabric for every panel the weather reaches, because indoor fabrics are for indoor use only. Save where a roof protects you: under a fully covered terrace, an indoor fabric can work as trim. Test a sample with a jug of water before ordering; if the water beads and rolls off, the finish is working.

Five places where the water shows you how the cushion is built.

- Water poured from jug
Pouring water straight onto the top is the simplest home test for a repellent fabric.
- Round beaded droplets
Round beads mean the finish is working and the weave is not wetting through.
- Drops running off
Water rolls down the boxing and off the piping instead of soaking the side.
- Stripe matched at corner
The stripe runs cleanly from top to side at the corner, even on a test piece.
- Slatted teak seat
Slats let any water that does get through drain away underneath.

What the jug is telling you
Somebody tipped a glass jug over a coral and white striped cushion on a teak seat. Good. That is the cheapest test there is, and the most honest.
Look at the top. The water sits in round beads instead of spreading into a dark patch. Round beads mean the water-repellent finish is working and the weave is not wetting through. Look at the corner: drops run down the side band and off the piping rather than soaking in. The stripe runs cleanly from top to side there too, matched at the corner even on a test piece.
Under it all, teak slats. Slats let whatever does get through drain away underneath. A solid seat would hold that water against the foam.
The coral stripe is a smart pick for a demonstration: clear water shows against the color and against the white. It is a cheerful pick for a patio or porch, too, and cheerful counts when the sky turns gray.
Now the part people skip, friend. Water-repellent is a promise; waterproof is a contract. A repellent finish beads dew and a passing shower. Steady rain finds the seams and the zipper eventually. Budget for that with a dry place to store your outdoor cushions between storms and over winter. It costs nothing.
