✨ Transform Your Tiles in Minutes

Tired of scrubbing stubborn mold, dirty grout lines, and unsightly stains? Old, discolored grout can make even the cleanest bathroom look terribly dated.

Don't spend a fortune on professional regrouting! Our Pro-Grade Grout Pen instantly revives your tile lines and restores your home to a pristine condition in just one stroke.

Transform Tiles Instantly
💧 100% Waterproof & Easy to Use

Simply draw over the existing grout! It applies smoothly, touch-dries quickly, and creates a long-lasting waterproof barrier.

Instead of just painting over the dirt, it effectively seals the gaps around toilets, bathtubs, and sinks to keep moisture and daily grime out.

100% Waterproof Seal
🛡️ Ultimate Durability (Wash & Go)

Unlike standard paints that wash away, our upgraded formula creates a heavy-duty, moisture-resistant shield.

Once cured, water and soap simply bead up and rinse right off! It withstands daily showers and routine cleaning without peeling or fading.

Frequently Asked Questions
How long does one pen last? +
One pen typically covers 150–200 linear feet of grout lines — enough for most standard bathroom floors or a kitchen backsplash. Coverage can vary depending on grout width and how heavily you apply it.
Is it waterproof for showers? +
After application, let it cure for a full 24 hours. Once cured, it forms a water-resistant seal that holds up well under regular shower use. For best results, avoid heavy scrubbing during the first few days.
What if I accidentally draw outside the lines? +
If the product is still wet, you can usually wipe excess off smooth tile surfaces with a damp cloth or paper towel. Once it dries, it becomes much harder to remove.
Is it safe to use around pets and kids? +
The formula is water-based, non-toxic, and low-odor. Many customers use it in homes with children and pets. As with any product, we recommend good ventilation during application and keeping the area clear until fully dry.
How fast is shipping? +
Orders are typically processed within 1 business day. Standard delivery to most U.S. addresses takes 5–8 business days, and you’ll receive tracking information by email once it ships.

Bathroom Grout Repair
★★★★★

Saved me $1,500 on regrouting

Moving out of my rental house and the bathroom tiles looked nasty. Took 20 mins to whiten everything. Got my full deposit back!

Kitchen Backsplash Before After

Kitchen looks brand new

Years of grease turned my white kitchen grout yellow. Look at the photo! It completely restored the original clean white look.

Grout pen application
★★★★☆

Good product, tip wears a bit

Covers deep stains instantly! Just a tip: if your tile lines are rough cement, don't press too hard or the felt tip gets fuzzy.

Get the 3-pack! One isn't enough

Thought 1 pen would do my entire bath floor, but ran out. Glad I bought the Buy 2 Get 1 Free deal. Matched my floor perfectly.

Precise tile pen
★★★★★

No messy cleanup!

Better than using liquid grout or silicone tubes. Flows smoothly like a marker and wipes off tiles easily if you make a mistake.

Arrived in 5 days, works like magic

Package came faster than expected. I used it along my shower base where mold keeps coming back. Make sure to wipe the area dry first! Covered the black lines easily. Ordering another 3-pack for my kitchen.

No chemical smell at all!

I have asthma so I can't use heavy bleach cleaners. This pen has practically no chemical smell. Dried touch-dry in a few mins. Showered 24 hours later and it stayed solid without washing off.

Waterproof seal actually works

Tested it around my bathtub where water collects all the time. After a month of daily showers, no peeling, no cracking, and no black spots coming through. Great quality!

Safe around pets and toddlers

We have two curious indoor cats and a toddler. Loved that this is water-based and non-toxic. It dried super fast and made our entryway tile floor look like new without dangerous chemical fumes.

★★★★☆ Reviewed in the US · application

Pro tip: Shake it well before use!

It works really well, but you need to follow the instructions: shake it with the cap on and press the nib down on paper to get the ink flowing. Once it starts, it glides super smoothly over tiles.

Best $35 spent on my home this year

I was quoted $800 to regrout my master bathroom shower. Used 3 pens from the bundle offer and did it myself in under an hour. The contrast against dark gray tiles is stunning!
