Fill the travertine to protect it from dirt

Travertine is a popular polishable porous limestone that is applied as a gemstone on both walls and floors. The pores generate sensitivity to dirt infiltrations. In particular, on and for floor coverings, they are closed and sealed in addition to the grouting by a flat spatula.

Porosity is not a defect

The most striking feature of the travertine are its holes. Depending on your personal taste, there are consumers for whom closing the holes is by no means an option. Structurally, nothing speaks against unsealed surfaces. Proper inclination of travertine surfaces outdoors will not cause frost damage.

The decisive argument for filling the holes is the cleanability and the susceptibility to soiling. While dirt can easily be washed out in the outdoor area, deposits in the travertine in the interior are only expensive to remove. Sealing the surfaces by filling the surfaces is common practice.

Just grout or seal

The grouting and filling of travertine is combined in one operation. The putty is spread on the surface. For this, the filler should be mixed slightly more fluid than for pure grouting. As a rule of thumb, about a ten percent higher water or liquid base material component can be calculated.

Many manufacturers and dealers offer pre-filled travertine. For these products, the trowel work is limited to the grouting as with ceramic tiles. If porous surfaces are to be closed or filled, the putty application follows after a first drying the washing of the spatially distributed putty. In a circular motion, the filler is moistened again and spread evenly with a special tool for filling, the wet sponge board.


An important aspect of filling travertine is the color scheme. As a putty always the same product in the joints and on the surface is processed in one operation. In most cases, a spatula color is chosen, which is based on the lighter areas of the travertine. If contrasting dark joints are desired, the surfaces of the travertine darken.

Tips & Tricks

If you appreciate uncoated and untreated travertine, especially as interior flooring, you should always keep some spare plates or tiles in stock. If it comes to damage or extreme contamination, simply replace the plates.
