How to Waterproof Your Camping Gear (Tents, Boots, Jackets)

Waterproofing isn’t a one-time feature — it’s a coating that wears off with use, washing, and UV exposure, and needs periodic renewal. This guide covers the three gear categories where waterproofing failure causes the most trip-ruining problems.

How waterproofing actually works

Most “waterproof” outdoor gear relies on two separate things: a waterproof membrane or coating (which blocks water entirely) and a Durable Water Repellent (DWR) treatment on the outer fabric (which makes water bead and roll off instead of soaking into the fabric surface). DWR wears off well before the underlying membrane fails — that’s why a jacket can “leak” even though the membrane itself is intact; the outer fabric has just stopped repelling water and become saturated.

Waterproofing a tent

1. Clean the tent. Pitch it and wipe down the rainfly and floor with a damp cloth — dirt and tree sap interfere with new coating adhesion.
2. Inspect seams. Check factory-taped seams for peeling tape, and the floor/rainfly fabric for any pinholes.
3. Reapply seam sealer to any peeling or exposed seams, following the product’s cure time exactly — rushing this step is the most common reason for seam sealer failure.
4. Apply a DWR spray to the rainfly and floor, focusing on high-wear areas like the floor corners and rainfly ridge.
5. Let it cure fully (typically 24 hours) before packing the tent away.

Do this at the start of each camping season, or sooner if you notice water no longer beading on the rainfly. See our camping tents review for tents that held up well in our rain testing without needing immediate re-treatment.

Waterproofing hiking boots

1. Clean off dirt and debris with a soft brush — built-up dirt blocks the treatment from reaching the leather or fabric.
2. Let boots dry fully before treating (never apply waterproofing to wet boots).
3. Apply a treatment matched to your boot material: wax-based for full-grain leather, spray-on silicone or fluoropolymer treatments for fabric/mesh uppers.
4. Apply in thin, even coats — two thin coats outperform one thick coat, which can clog breathable membranes.
5. Pay extra attention to the seam where the upper meets the sole, a common leak point.

Waterproofing a rain jacket

1. Wash the jacket using a technical cleaner (not regular detergent, which leaves residue that blocks DWR).
2. Check if water beads on the dry fabric. If it doesn’t, the DWR coating needs renewal.
3. Apply a DWR treatment — either a spray-on (better for high-wear areas) or wash-in (better for even full-garment coverage) product.
4. Tumble dry on low heat if the garment allows it — heat reactivates and helps bond the DWR coating. Check the care label first.

Maintenance schedule

Gear	Re-treat frequency
Tent rainfly/floor	Once per season, or when water stops beading
Hiking boots	Every 2-3 months of regular use
Rain jacket	When water stops beading, typically 1-2x per season with regular use

Frequently asked questions

How do I know when my gear needs to be re-waterproofed? Water should bead and roll off. If it soaks in or spreads flat, the DWR coating has worn off.

Does washing a rain jacket remove its waterproofing? Washing doesn’t remove the membrane, but residue can mask DWR performance — use a technical cleaner and re-apply DWR if needed.
