CGN White Grout Pen, Tile Grout Pen, Whitening Agent

Para cubrir juntas muy oscuras hay que dar varas pasadas pero va muy bien lo unico que no es muy duradero..osea que da para pocos metros

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.
