The Types of Grout

There are several types of grout frequently used in home renovation projects. The differing compositions of these types of grout make them dry at different rates, some taking longer than others. Knowing what type of grout you're using in your project gives you a much better window of reference for drying time. 


Cementitious Grout 

Cementitious grout is what you'll generally find in use in home renovation projects. In its base form, cementitious grout has a sandy rough texture. It needs to be mixed with water before application, which requires it to be made with a water-retentive additive. This additive prevents it from absorbing too much moisture, but as a result, makes it take longer to dry. It also requires some form of sealant to protect the grout. Cementitious grout, due to these factors, will take upwards of 72 hours to dry completely. 

Epoxy Grout

Epoxy grout is another type of grout found in home renovation projects. A more expensive grout, epoxy grout, is much harder to apply than cementitious grout. In return, you get an incredibly resistant grout that can last through weather changes and stains. Research and potential professional help are likely with this type of grout, but if you're willing to put in the effort, it could be the grout for you. 

Epoxy grout lacks any moisture additive and doesn't require sealing, unlike cementitious grout. As a result, its average drying time is drastically shortened to around 24 hours. 

There are other types of grout like furan grout, but these are generally used in industrial settings and don't serve the purpose of a homeowner. Cementitious and epoxy are the grouts to look out for.

Being somewhat higher in the air than the floor level, wall grout can experience a slight increase in the dry time. But overall, the experience will be much the same, highly dependant on grout type and humidity levels.

It should be obvious by now, but avoiding moisture is the main goal of this grouting stage. Yes, it's inconvenient not to have a bathroom for up to 96 hours, including a sealant application. Wet grout fundamentally loses structural stability, and moisture can even lead to issues such as mold. If you noticed water got on uncured grout, take care of it immediately. Run fans on the compromised area, and make sure no moisture gets sealed onto the grout. 

The best solution to prematurely wet grout is prevention, but accidents do occur. Keep in mind the problems that occur and act accordingly. 

Can you speed up grout drying time?

Generally speaking, the only thing you can do when drying grout is waiting, so be patient. Acting prematurely will only damage the grout and undo the work you put effort into. Because it's based on chemical reactions, there is simply no magic bullet that causes the grout to cure in a couple of hours instead of up to a few days. You can do several things to reduce and keep humidity in your bathroom to a minimum, even if you live in a humid area.

Purchasing and running a dehumidifier will help keep the air in your bathroom as dry as possible. This is a beneficial tool if you live in humid areas where keeping your house free of moisture poses a challenge. If you live in drier climates, it's likely more cost-efficient to skip this purchase, but you can use your own discretion. 

Remove Plants from the Room

Another contributing factor to humidity levels you might not have even thought of is house plants. Plants are constantly releasing moisture into the air, and their removal from your bathroom will help reduce moisture levels down. If your bathroom has a lot of plant life in it, definitely place them elsewhere for the duration of the grouting process. 

These are some easy steps you can take to reducing external factors that compound the drying process and keep problems from arising. Ultimately, however, patience is the key.
