Grout Pen White Tile Grout Paint Marker Replacement Tips: 5 Pack of Narrow 5mm - Waterproof Grout Paint Pen, Grout Colorant and Sealer Pen to Renew, Restore and Refresh Tile Grout

Very easy to use and very easy to replace at a very good price.

Works great

I'm trying to renew the grout on my kitchen floor without having it regrouted. I bought the winter gray grout pen and tried it on a small area. The pen works well; it is fairly easy to use, it covers well, and if you use a wet rag and clean up your mess as you go along, it is a rather quick job. However, the winter gray is actually white. I'm keeping it and might use it in another area of the house; I'm also buying a light gray pen and crossing my fingers. I don't know about its longevity since I have used only a small amount. It seems easy enough to clean off the tile, but I haven't cleaned the floor since I used the white (winter gray) pen last night. Overall, I'm looking forward to having renewed-looking grout at a good price with not a lot of work.

If going to use the pens, these tips are a must!

The replacement tips are good particularly if doing a large area. It takes a lot of force sometimes to get the colorant into the grout lines and the tips wear out fast.

This product is too narrow and requires multiple swipes to fill the grout line. Also it is too thin and doesn't really brighten the color well.

They work but don’t hold up to sandy grout and require replacement after 20 ft. of use.

Following directions closely they worked perfectly. My grout lines make the kitchen floor brand new again. Will definitely buy more to do my entrance and small hall way.
