What Kind Of Paint Can I Use On Grout?

Grout is a mixture of cement, sand, and water, used to fill gaps between tiles or stones in masonry construction. Over time, grout can wear, discolor, or even crack, making it look aged and unsightly. To rejuvenate your grout, many home renovators may decide to apply a fresh coat of paint. However, with numerous types of paint available on the market, selecting the right one can be confusing and frustrating. This article will guide you through the different types of paint that can be used on grout and help you make an informed decision.

To begin, it’s important to consider the type of surface you’re working with. Grout is porous and absorbs moisture, so using the wrong kind of paint can make the surface peel or flake. Some types of paints are designed to work particularly well for grout, and they include epoxy, acrylic, and latex. Each of these types has their own unique features and advantages, and knowing which one to use can make all the difference in the final result. The following paragraphs will explore the characteristics and benefits of each type of paint that can be used on grout.

Key Takeaway
You can use any kind of acrylic or water-based paint on grout. However, it is recommended to use a paint that is specifically formulated for grout, as it will adhere better and be more durable. It is important to clean and prepare the grout surface thoroughly before painting and to seal the painted grout for maximum longevity and protection.

Understanding Grout and Its Properties

Grout is a material that is used between tiles to fill gaps and ensure they are anchored firmly in place. It is essentially a mixture of sand, cement, and water, which is applied as a paste and left to dry. Grout is available in a variety of colors, with the most popular being white, beige, and gray, and it can be mixed with other additives to increase its durability.

Understanding the properties of grout is essential to selecting the right type of paint for it. Grout is porous, and this means that it can easily absorb liquid. Additionally, being a cement-based material, it can be susceptible to cracking and chipping over time. These properties must be considered when selecting the paint because choosing the wrong type of paint can lead to flaking, peeling, and fading with use. Therefore, it is critical to select the right paint for your grout, to ensure that it lasts longer and looks good over time.

Different Paint Types for Grout

When it comes to painting grout, there are different types of paint that you can use depending on your preferences and needs. One option is acrylic paint which is water-based and dries quickly. This type of paint is perfect for small areas and can be used on either interior or exterior grout. It is also relatively inexpensive and available in a wide range of colors, making it a popular choice for DIY enthusiasts.

Another option you can consider is epoxy paint. Unlike acrylic paint, this type of paint is oil-based and takes longer to dry. It is highly durable and resistant to water, chemicals, and stains. Epoxy paint is ideal for high-traffic areas and can be used on tiles and grout. However, it can be more challenging to apply and requires excellent ventilation. Ultimately, the type of paint you choose to use on your grout will depend on your preferences, budget, and project requirements. Therefore, it is essential to conduct proper research and seek professional advice before making a final decision.

Pros and Cons of Using Regular Paint on Grout

Pros of Using Regular Paint on Grout

Using regular paint on grout can be an easy and low-cost way to change the color of your grout without having to replace it entirely. This can be especially helpful if you are trying to update the look of a room on a budget. Additionally, regular paint can be easily accessible and comes in a variety of color options.

Cons of Using Regular Paint on Grout

However, there are many drawbacks to using regular paint on grout. Firstly, regular paint can quickly peel off or fade due to the high moisture levels in grout. Secondly, regular paint can conceal the natural texture of the grout, making it prone to slipping and causing safety issues. Finally, regular paint may not contain the right ingredients to withstand frequent cleaning or scrubbing of grout, leading to significant damage. Ultimately, while using regular paint on grout may seem like an easy fix, it may cause more harm than good.

Advantages of Epoxy and Acrylic Paint for Grout

Epoxy and acrylic paint are two of the most commonly used types of paint for grout, and with good reason. One of the main advantages of epoxy paint is its durability. It is resistant to water, chemicals, and abrasions, making it ideal for use in high-traffic areas like kitchens and bathrooms. Additionally, it is also resistant to bacteria and mold growth, making it an excellent choice for areas where hygiene is important.

Acrylic paint is also a popular choice for grout painting. It is easy to apply and dries quickly, making it ideal for any DIY project. Unlike epoxy paint, it is not as durable and may need to be reapplied more frequently. However, it is much more cost-effective than epoxy paint and is available in a wide range of colors, making it a flexible option for those who want to experiment with different styles and designs. Overall, both epoxy and acrylic paint are great choices for grout painting, and the choice between the two will largely depend on your individual needs and preferences.

Preparing the Surface Before Painting Grout

Before painting grout, it is important to properly prepare the surface to ensure the paint adheres well and produces a smooth finish. The first step is to clean the grout thoroughly, removing any dirt, grime, or existing paint. Use a grout cleaner or a solution of water and vinegar to scrub the grout lines with a stiff brush. Rinse the area with clean water and let it dry completely.

Next, if necessary, repair any cracks or gaps in the grout lines with a grout repair product or a mixture of grout and water. Smooth the repair with a putty knife and let it dry according to the product instructions. Once the grout is clean and repaired, mask off any adjacent surfaces with painter’s tape to protect them from the paint. Finally, sand the grout lines lightly with fine-grit sandpaper to create a slightly rough surface that will help the paint adhere better. Wipe away any dust with a clean, damp cloth before applying the paint.

Step-by-Step Guide to Painting Grout

Painting grout can be a great way to update the look of your tiled surfaces without having to completely replace them. Before starting, ensure that the grout is completely clean and free of any dirt or debris. It is also important to choose the correct type of paint for the job; epoxy paint works best on grout, as it is resistant to water, mold, and mildew.

To begin painting the grout, use a small brush to apply the epoxy paint to the grout lines. Take care to not get any paint on the tiles themselves. Once the first coat is dry, apply a second coat to ensure complete coverage. Allow the paint to fully dry and cure before using the tiled surface. With these simple steps, you can give your tiled surfaces a fresh new look with painted grout.

Maintaining and Touching Up Painted Grout

Maintaining and touching up painted grout is an essential part of keeping your tiled surfaces looking pristine. One of the primary benefits of painting grout is the durability factor, as it is much less prone to staining and discoloration than regular grout. To keep painted grout looking its best, it is essential to keep it clean using a mild soap and water solution. You should also avoid using harsh chemicals that can damage the painted surface.

When you notice signs of wear and tear on your painted grout, it’s time for touch-ups. Begin by cleaning the area thoroughly, and then apply a fresh coat of paint to the affected area. You should try to match the color of the touch-up paint as closely as possible with the original paint, which may require a bit of color-matching and testing. With proper maintenance and an occasional touch-up, your painted grout can last for years, and your tiled surfaces will look as good as new.


In conclusion, it is essential to choose the right type of paint that adheres well to grout. Before selecting the paint, one should check if it is compatible with the surface and has properties such as waterproofing, durability, and mold resistance. Although some people may prefer using regular wall paint, it is not recommended as it can flake, peel, and fade quickly, making the surface unsightly.

Apart from selecting the right paint, one should prepare the grout surface carefully before painting. This involves cleaning, drying, and priming the surface to enhance adhesion and prevent peeling. By following these painting tips, the newly painted grout can last longer, creating a vibrant and appealing surface in kitchens, bathrooms, hallways, and other areas.
