Washrooms are always wet. No matter how hard you try to keep them dry or wipe them. That makes it quite a humid place. Grout takes a longer time to dry in humid areas such as bathrooms, kitchens, etc. 

Also, during the monsoons, when the humidity is usually higher than the usual days, grout takes longer to dry.

2. Indoor vs. Outdoor

Indoors it takes around 3-4 days on average to dry grout.

What type of grout you are using also affects the drying time of grout. Here are the different types of grouts and their usual drying times. Have a look:

  1. Cementitious Grout: This type of grout is usually used for residential projects. It’s a dry, sandy textured grout which when mixed with water makes a fine paste. 

It takes around 3-4 normal days for cementitious grout to dry. Cementitious grout has water retentive properties that slow down the drying of grout. Some common examples of cementitious grout are Starlike Crystal grout and Polyblend plus.

  1. Epoxy Grout: It’s the fastest drying grout. Epoxy grout is usually considered ideal for tiles as it contains a hardener. Epoxy is durable for harsh weather conditions and cracks and stains. 

It is slightly more expensive than other grouts and has a quick-dry formula. It’s long-lasting. It dries within 24 hours which gives you all the reasons to use this one. Some common examples of Epoxy grout are Starlike Crystal and classic.

  1. Sanded and Unsanded grout: It’s a type of cementitious grout. This comes in two forms, one is sanded grout which is drier and may shrink or crack easily. The other one is unsanded grout which is easier to use and has a smooth texture than the sanded one. 

You can use the unsanded grout both for dry and wet places. The dry time of both sanded and unsanded is the same. It takes around 3-4 days to dry this grout.

  1. Furan Grout: Just like epoxy grout, Furan grout also has quick-drying properties. This type of grout is mostly used for quarry tile, in industrial setups, for brick pavers, in commercial kitchens, labs, and more.

It takes one or two days to dry furan grout. It’s good to bear harsh weather conditions.

If it doesn’t dry properly then there can be risks that your ceiling, or tiling may develop cracks within time. Here’s what happens if grout doesn’t dry properly.

  1. Weak joints, holes, cracks, peels and flakes, and gaps in the grout. If the grout hasn’t dried properly, these are the few things your walls might face. This weakens the hold of tiles on the surface and sometimes they might fall off or get cracks. 
  2. Cracks and crumbles. When the grout doesn’t dry properly, the group layering might develop cracks over time due to the moisture trapped in the cracks. 
  3. Discoloration. This is a commonly noted problem if grout doesn’t dry properly. You might have noticed that sometimes your tiles might look discolored or fainted at some parts. That’s because the grout didn’t dry properly.
  4. The least you want for your home or office tiles is to catch fungus or mold. But if the grout doesn’t dry properly, you are going to face this problem too. Due to cracked, flaked, and crumbled grout layering, the moisture locks in. When the surface remains wet for a longer time, it catches mold and mildew. Although there are many techniques to remove the mold from the surface without harming the tiles.
