Grout is a vital part of tiled surfaces, but over time, it can become discolored and dull. One quick solution many homeowners turn to is a grout pen, which refreshes the appearance of grout lines without the need for deep cleaning or re-grouting. However, one common question arises: after using a grout pen, do you need to seal it? This article explores what grout pens really do and whether applying a sealant afterward is necessary for long-lasting results.
Understanding What Grout Pens Actually Do
Grout pens are designed primarily for cosmetic improvement. They contain a pigmented ink or paint that sits on the surface of grout lines, essentially "whitewashing" or recoloring them. This makes old or stained grout look new without the effort of removing and replacing it. But it’s important to note that grout pens don’t physically change or repair the grout beneath—they’re more of a cover-up layer than a structural fix.
The application process is relatively simple. By running the pen tip along the grout lines, you deposit a thin layer of colorant that adheres to the existing surface. Depending on the brand and the condition of your grout, this layer may last for several months to a couple of years. However, since grout is porous, some pens also claim to provide a degree of sealing within the ink formula itself, which can be misleading.
Ultimately, grout pens should be thought of as a cosmetic tool rather than a protective barrier. They refresh the look of tiles quickly and affordably, but they don’t have the durability or water resistance that traditional grout sealers provide. This brings us to the question of whether sealing afterward is necessary—and in many cases, the answer leans toward yes.
Why Sealing May Be Necessary After Using One
Grout, by nature, is porous and absorbs moisture, dirt, and bacteria. This is particularly true in areas like kitchens, bathrooms, and laundry rooms where humidity and water exposure are high. While grout pens improve the look of grout, they don’t necessarily prevent water penetration, and over time, the ink layer can wear off. Sealing acts as an added line of defense to preserve both the appearance of the grout pen and the grout underneath.
Applying a sealer on top of a grout pen not only extends the life of the cosmetic coloring but also reduces staining and discoloration. A quality sealer fills the pores and forms a protective layer that keeps moisture out. This is especially important for shower floors, backsplashes near sinks, and tiled countertops where splashes and spills are common. Without sealing, the pen work may fade faster and require more frequent touch-ups.
In short, while it’s possible to use grout pens on their own, sealing afterward is often the best way to protect your investment of time and effort. For long-lasting results, a dedicated grout sealer ensures your refreshed grout stays cleaner, holds its color, and resists moisture damage better than relying solely on the pen’s coating.
Grout pens are an excellent way to give tiled surfaces an instant facelift, but it’s important to understand their purpose. They’re designed more for looks than durability. Sealing after using a grout pen provides that extra layer of protection that helps prevent fading, staining, and water damage. If you want your grout refresh to last longer and look its best, applying a sealer afterward is a practical and worthwhile step.
