Weather Sealing for RV Smart Locks: Gaskets, Glands & Sealant

Moisture is the silent killer of electronics. Let's keep your lock bone-dry without over-sealing the door.

1. Understand IP Ratings

Most RV locks hover around IP54 — splash resistant, not waterproof. If you want real weather protection, you'll have to upgrade the housing and sealing yourself.

2. Gaskets & Backing Foam

Use closed-cell EPDM or neoprene gasket material, 1–2 mm thick.
Cut cleanly around the perimeter of the lock body; avoid wrinkles that create leak channels.
Never use open-cell foam — it wicks water.

3. Cable Glands & Drip Loops

Where wires exit into the door cavity, install IP67 cable glands or rubber grommets.
Add a "drip loop" in the cable before the gland so water runs off instead of in.

4. Sealant Discipline

Use neutral-cure silicone (GE SCS2000 or equivalent). Acid-cure types corrode metal.
Apply a thin bead — sealing, not suffocating.
Wipe flush with isopropyl alcohol on your finger for a clean edge.

5. Annual Checkup

Every spring, inspect the gasket compression. Replace if hardened or cracked. Moisture tests? Tape tissue inside the cavity and drive in the rain. If it's dry, you win.

Dry lock = reliable lock. Weather sealing is quiet protection you never see but always feel.
