CGN ホワイトグラウトペン、タイルグラウトペン、美白剤

Did the work.

Easy to use BUT the pen tip wears out fast

Before using make sure to follow instructions. Initially nib would be dry, you need to press against a hard surface, so that the nib goes in breaking the seal and the white paint fills up the nib and then you can start using it. Everytime you feel the nib is dry you need to repeat this step. 7ml is less and costly. Maybe better to buy a white paint and a small brush and repaint the Grout.

I went over some grout lines which now look so much better.

Great for making a tired rental bathroom into something worth bathing in! You don’t get a lot of paint in one pen, so had to buy three to do a whole bathroom which isn’t massive. Left hand side of the picture is touched up, right hand side is without the application. Noticeable difference so am satisfied.
