3M™ Polyurethane Adhesive Sealant 550 Fast Cure is a low viscosity adhesive that has a fast set time and creates a permanently elastic bond. It is ideal for bonding a variety of similar and dissimilar materials. This one-component polyurethane adhesive provides fast cure time.
SS-3006TF is a fast curing, thixotropic adhesive silicone RTV. SS-3006TF is a 2-part RTV that when mixed, applied and cured, results in a clear RTV silicone sealant rubber to be formed within 10 minutes. A dispensing gun is required for the dual syringes on this fast-drying silicone sealant.
Silicone sealant generally cures within 24 hours. If it has been over 24 hours, check the silicone sealant “Use By” date on the package.
It might seem that certain shower sealants or caulks are dry to the touch quickly after application, but they actually take around 24 hours to properly cure fully. The curing process can be sped up or slowed down in accordance with the level of humidity within the shower enclosure, and the home in general.
Warmer temperatures generally lead to faster curing times, partly due to the fact that they usually involve higher humidity. However, regardless of the ambient temperature at the time you undertake your project, it's not a good idea to try to help the silicone cure faster by applying direct heat to it.
When the caulk gets wet, it will not cure properly. The formula that makes up your caulk will not be able to dry and cure or bond to the surface to that you have applied it. Not being able to dry in a timely manner will prevent the caulk from creating a proper seal.
Silicone sealant dries in 30-60 minutes, reducing the risk of smudging or damage to the caulk's surface. However, that is just dry to the touch. You should always wait at least 24 hours before attempting to shower after a caulk installation.
Water is the real threat to your sealant joints
Sealing joints on a damp surface should be strongly avoided, since silicone sealants generally do not adhere as well to moist substrates. If you want durable joints, never apply sealant in rain, freezing rain, snow or heavy fog.
It is fine to put another layer of silicone over an existing bead. The main consideration to remember is if the old bead is not fully cured you do not want to break the skin it has formed. Sometimes it is best to wait 2-3 days before putting any new product on so the old one has enough time to dry.
EVO-STIK Fast Set Sanitary Silicone Sealant is a rapid curing sealant that's ready to use in just 1 hour.
the silicone requires atmospheric moisture to cure. Using a hair dryer will have no effect on the cure time. If anything it would hinder the cureing process. Wet Area Speed Seal requires up to 72 hours to fully cure however it will have skinned over and cured sufficiently after 2 hours for the shower to be used.
Silicone adhesive sealant is versatile, but, unlike other adhesives, it must cure. Curing means letting it dry, and, although it is not necessarily a difficult process, it takes patience. Silicone adhesives can take as little as 24 hours to cure, but it may also take up to several days if the sealant is thick.
Use a fan to dry the adhesive.
Keep the fan by the adhesive for about 1 hour. You can also use a blow dryer to really speed up the process.
Polyurethene sealant can also be used effectively in joinery because the sealant cures quickly and exceptionally hard into wood joints. These joints can then be sanded and painted over for a top quality finish.
If caulking in winter, when the air is often drier, it may take silicone longer to cure—but don't try to speed the process by adding heat (e.g., with a hairdryer), as heat softens and can potentially melt silicone.

Generally speaking, most silicone sealants take about 24 hours to cure completely. After this point they can be safely exposed to water, moisture, and other conditions of normal use.
Let the mold sit for several days until there is no more orange smell and no signs of swelling. If the surface is still tacky, the mold is a lost cause. If this process cleans the surface well, keep in mind that the silicone didn't cure properly, so it may not perform well.
The most common reason caulk doesn't dry properly is because there is too much moisture in the air. Temperature and application thickness can also affect dry times. If after a week the caulk has not dried, remove the caulk and reapply with a new tube.
A silicone or caulk sealant is typically touch dry within an hour. This means that no dust or debris will stick to the sealant after this point. You will be able to brush off dust to keep clean, but it needs to be left longer before water can fall on the sealant.
Silicone coatings are moisture cured, meaning the more moisture in the atmosphere, the faster they cure. Rain doesn't wash the coating off, it actually cures it in place. Now, this doesn't mean you want to apply silicone in the rain. The rain will leave dimples in the coating that are harmless but are unsightly.
