DIY: Marble Tile Grout Lines

For marble tile flooring, there are a number of things that you have to take into consideration. Marble tile material is somewhat delicate and the grout lines that border each tile are also subject to the following:

  • moisture penetration
  • stains
  • growth of mold

Once there is a poor maintenance of the material over time, these lines can become unpleasing to eyes plus unhygienic while resting beneath your feet.

A great way to revive the look of a marble installation is by eliminating and then re-grouting these lines without having to go replacing the entire floor.

Prepare the following materials:

Grout saw, Tile Grout, Grout Float, Sponge, Marble Sealer, Foam Brush

Sealing

Take note: marble is a very porous material and if left unprotected, both dry dust and wet grout can soak into the pores of these tiles that will lead to permanent stains. Application of a coat of a marble surface sealing agent to the entire floor is the first thing that you want to do. This is necessarily important if the last time you applied sealer to it was more than six months.

Remove The Old Grout

Using a grout saw or an electric tool, start removing the grout from between the marble tiles. As you do not want to damage them, be careful to avoid the edges of the tiles. Make sure the area is well-ventilated as this will result in many grouts dust. Wear protective gear like breathing filter.

You can eliminate the grout down just the middle of the joints between the individual pieces of marble if you just want to do a fast job. However, if you want the best look and the most consistent color, strive to remove all the grout as thoroughly as possible.

Sweeping

Sweep or vacuum to remove the excess grout because when you’re done, there will probably be a layer of grout dust lying across the entire floor. Using an equal parts solution of water and vinegar, mop the floor. Before proceeding to the next step, allow this to dry completely.

Regrouting

Follow manufacturer’s instructions when mixing the grout. The color options available are massive for you to choose from. Use the grout float at a 30-degree angle when applying the grout to the joint in the middle of marble tiles, sweeping beyond the floor surface. Making certain not to allow it to dry on the marble, swipe excess grout as you work.

Rinsing the Excess Grout

To wipe the grout clear from the surface of the tiles, use a large and slightly damp sponge. Before it has a chance to set, best to remove the grout quickly. Try to avoid swiping bits of grout out of place with an incautious sweep of the sponge.

 Sealing

To dry completely, give the grout at least one day. Grout is a porous material thus, there is a need to apply another coat of chemical surface sealer to the floor. This will also need protection against moisture penetration and staining agents.
