If grout is too slack or liquid-y,, add more powder and mix well. Left too thin, it’ll shrink and crack. Good grout will need a little elbow grease to push into the tiles. If the grout is too dry and clumpy, moisten the sponge with water and squeeze just a dribble of water into the grout mix.
Can you add more grout after it dries?

Mix 1 cup of white granulated sugar into a gallon of hot water. Stir until the sugar fully dissolves. Pour the solution over the grout, or apply it to vertical surfaces with a sponge. Leave the sugar water to soak into the grout for about two hours.
What happens if grout is too thick?
When it’s exposed to water, it will disintegrate and fall out of the crevices between the tiles. Grout that is too thick won’t fully seal the tile because it’ll be too thick to reach the bottom of the cracks. Overly thick grout can also stick to the surface of the tiles and is difficult to remove when the job is done.

How long leave grout before wiping?
Let the grout set for 15 to 30 minutes, and wipe up the excess grout with a dense grout sponge soaked in water. (If you think it’s going to take you longer than 30 minutes to grout all of the tiles and be ready to move onto cleanup, you may have to work in smaller sections.).
Why is my grout not hardening?

This method churns the grout and introduces air into the mix.
Does grout get hard like cement?
The most common reason grout crumbles and disintegrates with minimal force is water – too much water. Virtually all powdered wall and sanded floor grouts are made from Portland cement. The presence of small, hard lumps or clumping means the grout may have started to mix with water vapor.
Can you put a thin layer of grout over grout?
ANSWER – It is possible to grout over existing grout if there is enough depth to do so. 1/8 inch depth may or may not be adequate depending on the type of grout used. A latex modified grout may work, but you have to properly clean the existing grout to ensure the new grout adequately bonds.
Can you add grout on top of new grout?
You can apply new grout right over the top of the old grout. To do this, all you need is a grout removal tool. Once you’ve removed the old grout, make sure to clean the area so there is no grout dust or debris that will get in the way of the new grout.
