Grout Pen White Tile Grout Paint: Waterproof Grout Paint Pen, Whitener and Grout Sealer Marker for Cleaner Looking Grout Lines - White, Narrow 5mm Tip (7mL) - 3 Pack

It worked perfect. Look like new. Love how easy it was to use.

I must say that I was skeptical based on other reviews but I am VERY happy with these grout pens. Very easy to use. Great results. Only downside is that 3 pens did not cover the entire bathroom. Plus I think it will require 2 coats. So I'm guessing I will need 9 pens in total. The other option was buying a can of the same material, which might have been cheaper in the long run. However the pen application is so easy to use that I will just stick to them. The photo shows the 1st application and the flooring closest to the door having no application at all. I will update with more photos when I am completely done.EDIT: First application was the most time consuming. I did a total of 3 applications with a total of 5 pens. The last 2 applications were super easy. HIGHLY recommend! Did NOT need 9 pens but will save the extras for touch up applications.

This stuff truly works! I had brown grout and two coats covered that ugly color. Love it!

Worked as I expected. Easy application and it enhances the tiles. My problem is that amount in the pen is smaller than I thought.

This pen is perfect for whitening/painting old grout to look new.

Really worked great on old discolored kitchen grout. Not everyone can afford to remodel. It made a huge difference! Wish daughter and son-in-law knew about this product 2 years ago.

These were awesome! 👏 easy to use and made my grout bright white!

Not impressed with these. The result looks great at the start but the tip degrades within a couple of minutes & makes precise application almost impossible. A better more durable application tip needs to be invented.
