There may be a situation that requires your sealant to dry quickly.

Sealant is a key part of any do-it-yourself effort to fix cracks or gaps in your home. Such leaks have been in the spotlight since the world woke up to how much energy -- thus, money -- the average household loses because of heat escaping through these holes. A good sealant product should be able to fill these gaps, cure and dry in a reasonably short space of time -- but there are a few steps one can take to expedite the process a little.


Step 1

Scrape off any excess sealant with a putty knife to aid the drying process. If a layer is too thick, it will take longer to dry, so scraping off any additional sealant will allow the air to get to the sealant and cut the drying time.

Step 2

Allow ample air into the room. There is a misconception that the hotter a room is, the quicker something will dry. However, this is not necessarily the case because humidity will curb the curing and drying process. You want the area to be a normal room temperature with plenty of ventilation.


Step 3

Ensure the sealant remains dry. This is particularly pertinent if you are sealing a crack or hole in a bathroom, as this will severely affect the drying time.

Step 4

Purchase a sealant that is advertised as "Quick Drying" if you are concerned about drying times. You will find most brands have a quick-drying version of their product as well as the regular version.


Do not use a hair dryer or any other type of accelerated drying process. This could case the sealant to crack and not do the job properly.
