Applying grout stain to the grout lines in a tile floor.

Most grout used in tile floors is porous and can become dirty over time. Applying grout stain, such as Polyblend Grout Renew, which is available in a range of colors, to the grout lines can give the floor a clean, new look.

Before applying grout stain, clean the grout thoroughly and allow it to dry. Next, apply the grout stain to the grout lines using a special applicator bottle, a small brush, or a soft toothbrush.

Before the stain dries, wipe any excess stain off the tile with a clean cloth. Watch this video to find out more.

Before you stain the grout in a tile floor, it’s important to clean it so the stain will stick properly. After the floor dries you can begin applying the stain to the grout joints.

Some products include an applicator to do this, or you can use an old toothbrush to rub in the stain. Before the stain dries completely, wipe off any excess from the surface of the floor tiles with a clean cloth.

Once you’re done your tile floor will look like new.

    I have old (50 years) saltillo tile floors in a large living, kitchen, dining area hall and bathroom. The grout everywhere is gray and only in the kitchen is the grout especially stained. I tried to strip and refinish it, but some tiles lack finish. What do I do first? Paint the grout or refinish the tiles (and because it’s there, the grout)?

    I have a kitchen floor with dirty grout and some random cracks in the grout. I would like to freshen up the grout and fill the grout cracks. I don’t want a method, however, that will require restaing the grout every year or 2.

    Can you offer any solutions to my problem?

    Also, what is a good product for cleaning and protecting my Living room laminated floor that looks like wood.

    Sincerely, Tony
