How long does it take for latex paint to dry out?

Open cans air dry in 2-7 days depending on humidity. For faster results, mix in kitty litter or commercial paint hardener — it solidifies in 15-30 minutes. Layer in a cardboard box if you have multiple cans.

Latex Paint Disposal in Seattle

Q: Where can Seattle residents drop off latex paint disposal?

King County / Seattle HHW — North & South Facilities accepts most household items. Free for all King County residents.

PaintCare Washington accepts latex paint at ~100+ Seattle-area drop-off sites for free. Containers up to 5 gallons.

Latex paint may NOT go in curbside garbage (not classified as hazardous in WA, but King County recommends PaintCare or HHW). For small amounts, dry out and dispose with lids off.

What to know in Seattle

Local rules and laws

Washington Electronic Product Recycling Law (RCW 70A.500, 2006): created E-Cycle Washington — one of the first state-level producer-funded e-waste programs in the US. Covers TVs, computers, monitors, laptops, tablets, e-readers, and portable DVD players. Manufacturers fund collection and recycling.
Seattle Director's Rule SW-404: bans batteries and covered electronics from municipal solid waste in Seattle (garbage, recycling carts, transfer stations). Violations result in a tag on the cart asking the resident to remove the items — no fines. Effective January 1, 2025 for batteries.
WA Battery EPR Law (SB 5144, signed May 11, 2023): producer-funded statewide battery collection program. Bans portable batteries (rechargeable and primary single-use) from the trash. Program implementation was still rolling out as of 2026; the law was driven partly by battery-caused fires at Seattle transfer stations and MRFs.
RCW 70A.205 — general solid waste management: electronics in the trash must be separated for recycling; disposal bans for lead-acid batteries, mercury-containing lights, and other universal wastes also apply. King County has additional local requirements.
PaintCare Washington launched based on the state's Paint Stewardship Law: PaintCare operates drop-off sites across the state funded by a per-container fee at purchase — covers architectural paints, primers, stains, varnishes, and sealers up to 5 gallons.

Useful local details

Seattle's two permanent HHW facilities (North and South) run completely different schedules: North is Sun-Mon-Tue, South is Thu-Fri-Sat. They're closed Wednesday and Sunday — exactly the days people try to go. The North facility was originally described as having a different address (12550 Stone Ave N at the Seattle.gov page lists Sunday/Monday/Tuesday).
King County HHW accepts waste from ALL King County residents, not just Seattle residents — the North and South Seattle facilities plus the Factoria (Bellevue) site and traveling Wastemobile. This is unusually generous compared to city-only programs in other metros.
Seattle's Special Item Curbside Pickup includes one FREE battery pickup per year, a free small electronics box per year, free curbside motor oil/used cooking oil, and free styrofoam pickup — a genuinely useful program many Seattleites don't know they have.
E-Cycle Washington does NOT cover computer peripherals (keyboards, mice, printers), contrary to what many Seattle residents assume. Those go to Best Buy/Staples or the HHW facilities instead.
The Wastemobile has been running since 1989 — one of the longest-running mobile HHW collection programs in the US. It visits ~20 locations/year across King County from February through October.
Battery-caused fires at Seattle transfer stations and in collection trucks have been a major safety driver behind both the Seattle SW-404 ban and the state battery EPR law. Seattle's South Transfer Station had multiple battery fires in 2024-2025.
PaintCare Washington accepts latex AND oil-based paint at the same drop-off sites — unlike some states where HHW handles the oil-based stuff. Sherwin-Williams, Miller Paint, and Rodda Paint are the most common Seattle-area PaintCare sites.
King County's Haz Waste Help Line (206-296-4692) also gives advice on safer alternatives to hazardous household products — a free consultation service.
