Water-based stains usually take less time to dry compared to oil-based stains. It can take 24 to 72 hours to dry before adding the polyurethane layer. Usually, water-based stains dry completely in about 24 hours, while oil-based stains take up to 48 hours to completely dry. You should wait longer, at least 3 days after applying the stain, before you can seal it with a top coat or sealant.
This is because the dye layer has to cure before the sealant can be applied. You can use these tips on how to tell if water damage is new or old to get important information. The last signal you can use to estimate the length is found by touching the point damaged by water. New water damage won't have had time to weaken the drywall or other material, so even if it feels damp, it will still feel hard.
The source of a water stain is usually something simple: a leak from a heating appliance, a leak from pipes or water that has entered through the ceiling. If you start to notice water damage in your home, it's best to act quickly, but it can sometimes be difficult to detect it right away. If a leak has left water stains on the carpet, Davies recommends absorbing as much water as possible as soon as possible. On the other hand, older water-damaged spots will feel soft and you can move them without much pressure or force.
