Where to take leftover paint in Howard County, MD (HHW Saturdays Apr–Nov)

Unofficial. Not Howard County. Not a hauler. One campus, three clocks: convenience center vs transfer station vs HHW Saturdays only, April–November. Maryland has PaintCare — link the locator, no store list. Last checked 15 Sep 2026

Hours and seasons change. Confirm on the official HHW page the morning you go. This page is unofficial and not the county. Not a hauler. Winter HHW alternatives beyond “typically three special Saturday collections”: not fully listed on the HHW page fetched — confirm before you drive Dec–Mar.

Which kind is it?

  1. Wet paint (latex or oil) on a Saturday, April–November?

    Alpha Ridge HHW · 8 a.m.–4 p.m.

    Residents’ Convenience Center, 2350 Marriottsville Rd. HHW accepts paint and paint thinners. Proof of Howard County residency (driver’s license). Residential only. Chemists at the analyzing tables.

  2. Latex you can dry at home?

    Solidify · then trash

    County landfill guide tip (research brief): air-dry or solidify latex with kitty litter, shredded newspaper, or paint hardener, then regular trash. Guide PDF fetch redirected/blocked today — treat as guide-sourced; confirm on Know Before You Throw / guide before relying on it.

  3. Architectural leftover paint any day of the week?

    PaintCare Maryland · locator

    Statewide program began April 2026. Free drop-off of PaintCare products (house paint, primer, stain, sealer, varnish that carried the fee). Typical site cap 5 gal/visit — call the site. Locator only — this page does not list stores. Aerosols / unlabeled / leaking: not PaintCare.

  4. Thinking weekday HHW because the dump is open?

    Wrong clock

    Convenience center: Mon–Sat 8 a.m.–4 p.m. (no trailers/box trucks per guide). Transfer station: Mon–Sat 8 a.m.–3 p.m. HHW is Saturdays only, Apr–Nov. Dump open ≠ HHW open.

  5. December–March?

    HHW seasonal off · PaintCare / dry latex

    HHW page: Saturdays April–November; “typically three special Saturday collections during the winter off-season” — dates: not stated on the page fetched. Prefer PaintCare locator or dry latex for trash until you confirm a winter Saturday.
