Pick your caulk, where it is and how thick the bead is. You get when it skins over, when you can paint it, when water can touch it and when it is fully cured, from the maker's own data sheet, as clock times from when you finished.
Your caulk's times
Shower after 30 minutes–24 hoursCaulked at 10:00 AM: shower from 10:00 AM tomorrow · smooth it within 5–10 minutes
Your room and when you finished
GE and DAP time their silicones at 73 °F and 50% humidity.
Quick answer: most caulk can get wet after 30 minutes to 24 hours, depending on the tube, and is fully dry or cured in 24 hours. A 100% silicone such as GE Advanced Silicone 2 is water-ready in 30 minutes, but only with a thin bead (3/16 in or less) in a room of at least 65 °F and 50% humidity; otherwise GE asks 8 hours. DAP’s 100% Silicone asks 12 hours, and an acrylic latex caulk such as DAP ALEX PLUS 24 hours, though you can paint it after 30 minutes.
How to use the caulk dry time calculator
- Pick your caulk. Not on the list, or not sure? “A 100% silicone” or “an acrylic latex caulk” gives the range of those tubes here.
- Where is it? A tub or shower, a sink or counter, trim you will paint, or a window or door: the answer leads with the time that matters there (water, paint, rain).
- How thick is the bead? It changes the answer: GE’s and Gorilla’s 30 minutes holds only for a thin bead, and GE’s paintable silicone cures a few millimeters a day.
- Open “Your room and when you finished” under the answer: the room’s temperature and humidity (it says when yours will be slower, or too cold to caulk at all) and the time you finished. Every time on the list becomes a clock time. Copy link keeps it.
Caulk dry times, from the makers’ data sheets
Each time is the maker’s own, from its technical data sheet (Gorilla’s from its product page). “—” means the sheet does not give that time; the calculator never fills it in from another tube.
| Caulk | Skins over | Paint | Water | Fully dry or cured |
|---|---|---|---|---|
| GE Advanced Silicone 2 Kitchen & Bath | 30 minutes | Not paintable | 30 minutes or 8 hours | 24 hours |
| GE Supreme Silicone Kitchen & Bath | 30 minutes | Not paintable | 30 minutes or 8 hours | 24 hours |
| GE Paintable Silicone Supreme Kitchen & Bath | 15–20 minutes | 1 hour or 2 hours | 30 minutes or 8 hours | 2–3 mm a day |
| DAP SILICONE MAX Kitchen, Bath & Plumbing | 10–25 minutes | Not paintable | 30 minutes | 24 hours |
| DAP 100% Silicone Kitchen, Bath & Plumbing | 10–20 minutes | Not paintable | 12 hours | 24 hours |
| Gorilla 100% Silicone Kitchen & Bath | — | Not paintable | 30 minutes or 24 hours | 24 hours |
| DAP ALEX PLUS | 30 minutes | 30 minutes | 24 hours | 24 hours |
| DAP ALEX FAST DRY | 15 minutes | 20 minutes | 24 hours | 24 hours |
| DAP ALEX Painter’s | 30 minutes | 2 hours | 24 hours | 24 hours |
| DAP KWIK SEAL Kitchen & Bath | 30 minutes | 2 hours | 24 hours | 24 hours |
| DAP DYNAFLEX 230 | 30 minutes | 2–4 hours | 24 hours | 24 hours |
| DAP KWIK SEAL ULTRA | 10 minutes | Not paintable | 4 hours | 24 hours |
“30 minutes or 8 hours”: GE’s footnote reads “Exposure to water possible in 30 minutes with bead size max 3/16” (4.8 mm), temperature min 65°F (18.3°C) and humidity min 50%. Otherwise, sealant should not be exposed to water for 8 hours.” GE’s paintable silicone allows a 1/4 in bead for the same 30 minutes. Gorilla gives its 30 minutes for a 3/16 in bead at 70 °F and 50% humidity, and 24 hours otherwise. DAP’s own silicone makes no such promise: “Allow sealant to cure for at least 12 hours before exposing to water.”
Silicone or latex: what slows each one down
An acrylic latex caulk dries as its water leaves, so damp, cool air slows it. DAP’s latex sheets all say “Cooler temperatures and higher humidity will slow down dry time.” A silicone is the other way round: it cures with the moisture it takes from the air, so a cold, DRY room slows it. GE: “Cure time is significantly increased in cold temperatures and/or low humidity conditions.” DAP’s SILICONE MAX gives its times “At 73°F & 50% relative humidity, sealant is water resistant at 30 minutes & reaches full cure in 24 hours”, and adds that low humidity may slow the cure. None says by how much, so the calculator does not guess: in a room that is slower for your tube, it tells you to expect longer.
A silicone also needs air to cure: DAP warns “Sealant will not cure in totally confined spaces.”
When can you paint caulk?
Only a paintable one, and only after its paint-ready time: 20 minutes for DAP ALEX FAST DRY (with a brush or roller; spray paint right away, DAP says), 30 minutes for ALEX PLUS, 2 hours for ALEX Painter’s and KWIK SEAL, 2 to 4 hours for DYNAFLEX 230. DAP’s sheet for ALEX PLUS: “Allow caulk to dry at least 30 minutes (longer in cool or humid conditions) before painting with latex or oil-based paints.” GE’s Paintable Silicone Supreme takes latex paint after 60 minutes under the same conditions as its water time (“Otherwise, sealant should not be painted for 2 hours”), and oil-based paint after 24 hours over a latex primer. A 100% silicone cannot be painted at all: DAP’s and Gorilla’s sheets say “Not paintable”, GE’s “Non-paintable”.
Five worked examples
A tub in GE Advanced Silicone 2, a thin bead. Shower after 30 minutes, cured in 24 hours: caulked at 10:00 AM, the shower can run at 10:30 AM, but GE asks you not to touch or clean the bead for 24 hours.
The same tub, a 1/4 in bead. Shower after 8 hours, cured in 24 hours: the bead is thicker than GE’s 3/16 in line, so the sheet’s own 8 hours apply.
A shower in DAP 100% Silicone. Shower after 12 hours, cured in 24 hours: caulk it in the morning and shower that night.
Baseboard trim in DAP ALEX PLUS. Paint it after 30 minutes, fully dry in 24 hours: caulked at 10:00 AM, the paint can go on at 10:30 AM.
A kitchen sink in DAP KWIK SEAL ULTRA. Water-ready in 4 hours, fully dry in 24 hours: run the tap from 2:00 PM, and don’t plan to paint it (it is not paintable).
Common mistakes
- Counting on “30 minutes” with a thick bead. GE’s and Gorilla’s 30 minutes are for a 3/16 in bead in a warm, humid enough room; a thicker bead waits 8 hours (GE) or 24 (Gorilla).
- Wiping the new bead clean. Water-ready is not cured: GE and DAP’s 100% Silicone both say “Do not touch or clean sealant for 24 hours”.
- Painting a silicone. It will not take paint. Use a paintable caulk on trim, or GE’s paintable silicone.
- Filling a deep gap with caulk alone. DAP’s latex sheets stop at a 3/8 in or 1/2 in deep joint, GE at 1/2 in: past that, push in a foam backer rod first.
- Caulking outside before rain. DAP: “Do not apply when rain or freezing temperatures are forecasted within 24 hours.”
- Caulking a cold room. DAP’s latex caulks ask at least 40 °F, GE’s paintable silicone 41 °F.
Caulk drying: questions people ask
How long does caulk take to dry?
Skin-over in 10 to 30 minutes, fully dry or cured in 24 hours, for every tube here. When it can get wet depends on the tube: 30 minutes for DAP SILICONE MAX (and GE’s silicones with a thin bead), 4 hours for DAP KWIK SEAL ULTRA, 12 hours for DAP 100% Silicone, 24 hours for DAP’s acrylic latex caulks.
How long does silicone take to dry?
Silicone skins over in 10 to 30 minutes and cures in 24 hours (GE, DAP, Gorilla). GE Advanced Silicone 2 and Supreme are water-ready in 30 minutes with a bead of 3/16 in or less at 65 °F and 50% humidity, otherwise after 8 hours.
How long does caulk need to dry before showering?
From 30 minutes to 24 hours, by the tube: 30 minutes for DAP SILICONE MAX and, with a thin bead, GE Silicone 2 and Gorilla; 4 hours for KWIK SEAL ULTRA; 8 hours for GE with a thicker bead; 12 hours for DAP 100% Silicone; 24 hours for KWIK SEAL and ALEX PLUS.
How long to let caulk dry before painting?
20 minutes for DAP ALEX FAST DRY, 30 minutes for ALEX PLUS, 2 hours for ALEX Painter’s and KWIK SEAL, 2 to 4 hours for DYNAFLEX 230, and 1 to 2 hours for GE Paintable Silicone Supreme (24 hours under an oil-based paint). A 100% silicone cannot be painted.
How long does it take for silicone caulk to cure?
24 hours for GE Advanced Silicone 2, GE Supreme, DAP 100% Silicone, DAP SILICONE MAX and Gorilla. GE Paintable Silicone Supreme cures 2 to 3 mm every 24 hours, so a 1/4 in bead takes two to three days. Cold, dry air makes every one of them slower.
How long before silicone can get wet?
30 minutes for DAP SILICONE MAX; 30 minutes for GE and Gorilla only with a thin bead in a warm room (otherwise 8 hours for GE, 24 hours for Gorilla); 12 hours for DAP 100% Silicone.
How long does caulk take to cure?
DAP’s latex caulks are fully dry through in 24 hours; the silicones here cure in 24 hours, slower in a cold or dry room.
