When you want a quality product that is more cost-effective, powder grout is the best option.

It can be overwhelming to choose a grout style, such as sanded or unsanded, epoxy or latex, colored or neutral. A project’s size and whether or not you need a custom mix make it easier to decide whether to use premixed or powdered grout.



Premixed grout can be installed straight out of the container, saving time and simplifying grouting. Making sure the right amount of water is added or the consistency is achieved need not be a concern. Due to its ability to be purchased in small quantities, when used on smaller jobs, it is less expensive. Some premixed grouts also already contain latex or urethane, which improves adhesion and eliminates the need for sealing.


Premixed grout can be more expensive than purchasing dry grout in bulk and mixing it yourself for large jobs. Also, we can store dry grout for long periods to be used for several jobs over time. Mixing your grout also lets you add the exact ingredients you desire, such as latex or custom color.

Does Grout Go Bad?

Providing a nice finish for many years, good grout holds tiles in place and locks them in place. However, grout that is too old or installed incorrectly will rapidly deteriorate and won’t be able to lock tiles in place.

Bad Grout

If not exposed to freezing temperatures, powdered grouts usually expire after one year, and epoxy grouts can be stored indefinitely if they are sealed. For powdered grout to become firm and stable, it needs to be mixed with water and allowed to cure. The grout powder should not be used if it has clumps or small, hard lumps, which indicate that it has likely been exposed to water or humidity. Mud that is lumpy is either already bad or getting worse.

Bad Installation

When the grout is fine, even grouting jobs can be problematic. Grouting requires that the right amount of water is added to the mix. When grout is too wet, it is runny and does not dry and cure properly. Adding more water to the batter will only result in a thinner paste. Mix the batter to a consistency similar to cake batter. Rather than salvage the dried grout, mix a fresh batch if the grout starts to dry.

Does Premixed Grout Need To Be Sealed?

How to Use Premixed Grout

Tile is usually laid down with grout, which is mixed up to fill in the gaps between the tiles. Once the grout is cured, this provides added stability and waterproofing to protect the material under the tiles. As you might have guessed, Premixed grout skips the entire “mixing” stage and allows you to apply the grout to the tile as soon as the tile adhesive dries.

Step 1

Remove any dirt or grime from the tiles by using a damp sponge, then rinse out the sponge and set it aside.

Step 2

Use a trowel to spread a glob of the premixed grout

onto the tile.

Step 3

To make the grout stick to the seams between the tiles, hold the grout float at a 45-degree angle. When working the float over the tiles, make sure to apply significant pressure. Keep your float perpendicular to the seams to avoid digging out the grout.

Step 4

Once all the seams in the working area have been filled with the premixed grout, continue to apply it over the tiles.

Step 5

With a damp sponge, remove any excess grout. After removing most of the grout with circular motions, wipe parallel to the grout lines one more time. Don’t forget to rinse out the sponge every now and then in the bucket of water. After all the grout has been removed, wipe the grout lines down with a clean sponge one last time.

Step 6

Wipe off the grout and apply it again until all of the seams between the tiles are covered.

Step 7

Let the grout dry, then return to the tiles and use clean rags to wipe off the film that appears around the grout. You may need to dampen the rags to clean off the film thoroughly. Give the grout time to dry following the manufacturer’s instructions.

Step 8

Seal all grout lines with grout sealer.
