Should I grout or caulk kitchen backsplash?

So you’re renovating your kitchen and have decided to add a backsplash. You’ve measured and cut the tile, but now you’re faced with a question – should you grout or caulk it?

Both options have their pros and cons, so how do you know which is right for you? In this blog post, we’ll break down the differences between grouting and caulking a backsplash, so you can make the best decision for your home.

So, Should you grout or caulk kitchen backsplash? If you are looking for the best long-term results with your backsplash, caulking might be a better choice than grout. However, if you need immediate results or prefer visible joints in your backsplash (for example because of design preferences), then grouting will probably be more suitable for you.

For a more detailed insight into this subject, let’s scroll through the rest of the post.

What is the difference between grout and caulk?

Grout is a cement-like material used to fill gaps between tiles, while the caulk is a sealant designed to stop the passage of air and water.

In general, grout does not have much flexibility or elasticity, making it likely that grouted joints will start to fail over time. This is especially problematic in high-moisture applications such as kitchens underneath a countertop backsplash.

A quick tip: To make your tiling project a success, it is critical to have a good knowledge of tile sealants, low-temperature adhesive, use of adhesive as grout, and the use of Quartz backsplash.

In what cases should I prefer caulking over grouting?

Caulking has many advantages over grouting when it to kitchen backsplashes. Caulking is more flexible and elastic than grout which makes caulking joints less likely to fracture over time.

Caulking can be easily removed and re-applied when needed; caulking also insulates against air leakage, helping prevent mold growth.

In what cases should I prefer grouting?

Grouting is useful for larger areas in which you do not want visible gaps in the finished surface and caulk has a shorter open time than grout (grout may be applied within 20 minutes while caulk requires at least 45 minutes before it begins to dry).

However, even though compressing the joint between tiles will sometimes make the installation of grout easier (but not always), both grout and caulking require professional installation.

What takes more time to do, caulking or grouting?

Grouting takes longer than caulking to do properly. Proper grouting may take up to 10 hours if the tiles are very large, while caulking is usually done in less than four hours.

Is grout or caulk more durable?

Caulk is more durable than grout because it has elastic properties that help it expand and contract with movement, helping prevent joint failure over time.

Grout expands when exposed to moisture, but does not have the flexibility needed to compensate for this expansion – this can lead to cracks along the joints of your tile backsplash.

What are the elements which determine how much time I will spend on tiling my kitchen yourself?

Generally, tiling a kitchen takes between 3-7 days. This time will be determined by the size of your kitchen, whether you are using patterned tile, the materials you use, and whether or not you have professional help.

Here is a great video tutorial on installing caulk on a kitchen backsplash.

What is more expensive, grouting or caulking?

Caulking is usually more expensive than grouting because caulking does not require tile or professional installation, whereas grout requires both.

Due to the fact that caulking joints are easier to remove and re-apply if necessary, you may even save money by using caulk over grout in the long term.

Does grouting make a stronger seal?

Grouting a tile backsplash does not form watertight seal-like caulking – this means that your kitchen sinks could be at risk of getting leaks from behind the tiles.

In addition, grout has been known to absorb stains from dampened foods such as tomato sauce and tea. This can create unsightly marks on your finished backsplash surface.


To conclude this blog post, grouting is most useful for larger tiles, whereas caulking is more flexible and easier to remove if necessary. Caulking joints are less likely to fail over time, while grout expands when exposed to moisture.

Finally, caulking is usually cheaper than grouting because it does not require tile or professional installation.


What is epoxy grout?

Epoxy grout is a type of cement-based mortar (similar to regular grouts) that can be used as a sealant between tiles and has similar characteristics as caulking.

Epoxy grouts resist deterioration from moisture and high temperatures and will not mildew or support mold growth. However, they may crack more easily than traditional grouting compounds under excess stress (such as heavy objects resting on them).   

Do I need to wait for epoxy grout before setting my countertop backsplash?

No, you should not need to wait. Epoxy grout is a better choice for your countertop backsplash than caulking because it provides a lasting sealant between the walls and tiles.

If you do decide to use epoxy grout, be sure that the tiles are set before the epoxy starts to dry, or else your tiles may fall off of their backing. In general, though, caulk is a more attractive and versatile option for countertops because it can also be used in many other areas around the kitchen (such as inside cabinets) and comes in different colors.

Should I opt for custom tile backsplashes or pre-fabricated ones?

If you want versatility and variety in terms of designs and patterns, you will want to choose custom tiles. If you want a simpler, more uniform look, pre-fab tiles are better for you.    

What is the difference between white grout and gray grout?

White grout is usually made with light or bright pigments to provide a clean, spa-like ambiance in kitchens.

Gray grout is often used when there are contrasting tiles because it goes well with both dark and light shades of marble, glass tile, ceramic tile, granite, slate, and porcelain. It also works well when the space around your backsplash is to be kept clean (such as at the kitchen sink).

It’s best to caulk if you want the joints between tiles to remain hidden behind your backsplash for a clean, sleek look and grout if you want your tile backsplash to be durable and elastic.
