How to Mix Grout

Action 1

Before selecting the accurate grout for your tiles have a quick view of grout types.

What is Sanded Grout?

Sanded grout is a combination of filler particles, cement, pigment, and sand in a dry state. It is advised to use sanded grout for margins wider than ⅛ inch for the fact of the sand works better at remaining in the joints. There are fewer chances of its breakage as it cures.

It presents a coarser, grainy surface to touch and display because of the amount of sand available in this type of grout.

It is considered safe for delicate flooring such as marble, polished or honed tile they may get scratches with sanded grout.

Any type of tiling you are wearing in your room you must want to clean off the grouting mess as soon as possible before it gets stubbornly hard. After cleaning off the excess grout give sanded grout a good 72 hours to settle the seal to avoid spotting and discoloration.

A variety of colors are available in sanded grout. Pick the color by following your tiling aesthetic theme.

What is Unsanded Grout?

Unsanded grout particles formula is as same as sanded grout, the difference is only the absence of sand of course.

This type of grout without the bulk of sand works better for narrow joints and is good for a silky smooth finish. But of course, it has less power to bind objects than sanded grout.

Such as marble tile and most mosaics works best, as it is designed for scratch-prone tile material according to Austin, Texas-based tile setter Sean Chavoustie.

While it needed more effort to reach it into the margins between tiles, unsanded grout worked as stickier. To avoid the collapsing of un-sanded grout you must need to ensure that each margin is completely filled.

Action 2

Select a grout additive as per the requirement

Sealant Additives

Sealant is a premade- solution, easy-to-use formulated with the combination of grout powder in lieu of water.

Sealant is created with the idea of making grout joints less solvent for water absorption, keeping the grout safe against stains, mildew, and is taking the place of secondary sealants and is generally applied after installation.

Sealants enhance the quality of grout’s color. It is also known for maintaining the shade of color. Some sealant additives creators claim that it empowers the grout.

Before picking up a sealant, have a compatibility match with your grout and sealant.

Some sealants are particularly designed for sanded grout and some of them are designed for unsanded grout. Pick wisely by having the correct knowledge about your grot type.

According to Chavoustie, some products’ chemistry formulated together are not matched well. They are generally considered durable in chilling/fussing conditions.

Colorant Additives

If ready-made grout colors in the market are not your cup of tea. You can make your grout tea as per your taste by personalizing the white grout with grout colorants in the flooring industry.

You can easily and simply add these powdered pigments into your grout to clarify your tiling space. You can customize the pigment level by adjusting the amount to get your favorite shade.

Having the knowledge into your account that when the grout is wet it’ll look darker but after drying it will be a bit lighter than what you saw already. To get a more exact match, follow the manufacturer’s set of instructions for adjusting ratios of pigment.

To add ambiance to the margins between tiles you are refilling, consider putting glitters in any type r color of shiny textures to your grout solution. The pigment can also do the job by sparkling in the dark.

Latex Additives

To enhance adhesion, workability, durability, strong impression and freeze-thaw resistance latex additives are added to grout.

Latex additives can maximize the bond power and turn the grout a tougher cure. The potential advantage of this additive is making the tile joints less affected by water digestion.

Action 3

Add water to grouting powder per manufacturer’s instructions.

Chavoustie recommends that Before adding the grouting powder, pouring the proper amount of water in the mixing bucket will make the task easier to mix because if you first put the water in,” he says, that to get the correct consistency you can pour more water as per requirement.

Add approximately a quarter or half of the grouted powder into the bucket. In case you get a blunder adjust the water-to-powder ratio in the mixing procedure.

Follow the manufacturer’s mixing instructions for mixing grout ratio with water. Always start putting less water than recommended you always have the chance to add more water later.


Never use well water or hard water for mixing grout. Minerals from the water can result in untidy white residue, as moisture digested into the grout. Always use distilled water.

Action 4

Slope mixing vessel and blend with a grout-mixing knife.

Position the bucket to about a 45-degree angle it will make you able to see the substance and make you able to mix it perfectly with the help of a grout mixing knife.

Mix, mix, mix until all the lumps vanished and it comes in the form of a well-blended paste.


Avoid using a corded drill with a paddle attachment to mix grout. Machine mixing can cause air bubbles, may weaken the grout, and has potential discoloration hazards.

Action 5

Have slime feel by maintaining the grout thickness measure by putting powder or water.

The peanut butter you must have tasted and felt its texture, it is creamy smooth, and heavily thick. The consistency of grout should exactly match the thickness and fluent nature of peanut butter.

Grout for walls should be slightly thicker than the consistency of peanut butter.

If the peanut butter is not your cup of tea you don’t get the point here is another measuring tool that’ll help you to meet the exact consistency scale of your grout.

Bread dough is soft, you can grab how much you want it will not change its shape, and by squeezing it doesn’t leak water. Check the grout’s consistency.

Chavoustie says grout mixed for floors should be “smooth peanut butter consistency” while grout for walls should be a bit thicker.

Other tiling pros describe the perfect consistency as being akin to soft bread dough, where you can grab a handful and it maintains its shape, and, if squeezed slightly, doesn’t leak water.

Thin consistency will leave cracks. The right consistency grout will required elbow grease to reach into the tiles. If it’s extra hard to apply adjust it by adding water with the help of a sponge moisten the sponge and squeeze a little amount of water into the grout mixture.

Adjust the consistency by repeating this process in a gradual motion to reach the right level of grout consistency as mentioned before.

Step 6

leave the grout for more than 10 minutes to bond

Letting the grout stay for 10 minutes will allow it to chemically bond well. Maybe during the grout slaking, moisture fully sucks all the powder, so you need to add more water as per requirement.

This will make the grout stronger and have fewer chances of cracking the solution and losing the margins. The grout should be thicker so add the water carefully.

Action 7

Mix it again thoroughly by using a grout knife

Mix enough of your solution or paste of grout, and feel satisfaction to achieve your DIY tile aim.
