Things to consider before painting grout

Choose the right paint for grout

Grout paint is one of the most important aspects of choosing the right paint for your home. When it comes to grout, there are two main types: porcelain and cement.

Porcelain grout is much denser than cement grout, making it more durable and less likely to chip or crack. It’s also less likely to absorb stains, so it’s a good choice for high-traffic areas like kitchens and bathrooms.

Cement grout is more porous than porcelain, so it’s more likely to absorb stains and dirt. It’s also more likely to crack and chip, so it’s not as durable. However, it’s much easier to work with and can be less expensive.

Prepare the surface

Before you start painting, it’s important to make sure the grout is clean and free of any dirt or debris. You’ll also need to rough up the surface of the grout so that the paint will adhere properly.

What Type of paint can be used on grout?

Paint can definitely be used on grout, but you need to make sure that you use the right type of paint. You don’t want to use regular paint because it will just chip and flake off. You want to use waterproof paint that is made specifically for grout. This way, your grout will be protected from moisture and stains.
