Sounds about right? Let’s jump into the main part then!

Why Do We Mix Sanded And Unsanded Grout?

Unsanded grout is used in a joint that has a width of less than ⅛ inches. The texture of this grout is smooth and this makes it hold to vertical surfaces really well. This is why unsanded grout is good for wall tiles that are made of ceramic. 

Sanded grout, on the other hand, is a bit different. It is used for wall and floor tiles joints that have a width of more than ⅛ inches. This grout is useful for resisting shrinkage and cracking. 

Both types of grout are good in their own ways. But when you mix them things get even better. 

How? Let’s be more specific-

Sanded grout is thicker than grout that has not been sanded. It’s also more long-lasting and more durable. 

For that reason, you don’t have to worry about your grout going bad. When unsanded cement grout cures, it shrinks and pulls away from the tiles. 

The material will not shrink as much if sand is included in the grouting mix. This is because of the significantly higher aggregate material to cement ratio. Thus, mixing sanded and unsanded grout is helpful.

3 Simple Directions To Mix Sanded And Unsanded Grout

We already know that we can mix them together. In fact, combining them would be remarkable at times. 

Curious about the mixing process?

Just follow the directions provided below-

Direction 1: Processing The Sanded Grout

First of all, determine the precise amount of powder you’ll need to get started. Check out your product’s instructions for this information. 

When you’re mixing the sanded grout, make sure to use small batches. Because this would let the grout not dry out too quickly. But don’t forget to clean your grout if it’s unsealed.

This would also help you to seal the grout for later use. This is applicable if you have any leftovers as well. 

Now, add ¾ of the total water given in the product’s instructions and start mixing. You can do it with a trowel. You may also do it using a drill. In case you use a drill, go slow. Because if you don’t go slow, it’d create excessive air bubbles weakening the mix.

For more control, soak a sponge in clean water and squeeze it over the mixture. You should now see your grout clinging to the trowel like smooth butter. By the way, you can use this mixture to fix blotchy grout too.

Direction 3: Slackening The Grout Mixture

Let the grout sit undisturbed for 5 to 10 minutes. This would help the grout to strengthen or slake. Then stir the grout again to loosen it up before using.

Question: Can I consider mixing grout with two different brands?
