Grout Pen Grey Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Grey, Narrow 5mm Tip (7mL)

worked great very easy to use

Something so simple made such a difference. The grout pen covered and hid the damage in the grout of my kitchen tile floor. Would recommend for an easy fix.

Not sure about longevity but I opted to try this on my traffic master peel and stick floor tile. I installed it after purchasing at Home Depot and my only mistake was using white grout. Even w sealing precautions, the white grout just looked dirty. This pen alleviates that for which I am grateful but it’s a trade off for the imperfect lines.I applied the pen, waited overnight and mopped to remove the excess hoping it would come off the tile and remain only in the grout lines. It seemed to come off the peel and stick tile which was a relief but still the lines look like someone took a marker over them and some of the color came up with it.I am hoping that applying a second coat will keep it dark for at-least a while but only time will tell.Overall I think it does its job. It looks better than the yellow white grout, just obviously not a high end grout job and again not sure how long it will last.

My small bath has gray grouts that looked faded. I tried this grout pen at obscure area first and found the actual color to be a lot darker than the color shown on the cap of the pen. A very dark dull gray, charcoal would have been better. However the pen is very easy to use, clean application. I’d like to exchange for a lighter gray but there was no such choice.

This is pure gold! Amazing and fast. Suggest getting extra tips for the pen

Used it to add dimension to a large kitchen with white subway tile backsplash. Fast and easy to apply, just wipe off excess with a wet napkin or scrape off (smooth) tile after it dries. Held up amazingly well and easy to touch up.

This is a very large tip. I have a 1950s old fashioned ceramic floor and the tip on this marker is huge so the pen is much wider than the grout and the paint comes out very fast. The result is awful and cartoon like. The grey is a very dark grey. Thank goodness I just did a corner I can cover with a paper can. Awful product but might work for a really wide grout and for someone who is very fast in applying it!

Works well
