It can be used in wall coverings, usually cut into tiles. It is not suitable for use on kitchen counters or floor coverings. Tuff stone is generally preferred in masonry and garden arrangements.

The ash is very fine grained, so only the rock fragments and pumice are identifiable. A rock with a pyroclastic texture is termed a tuff if the largest fragments are less than 2.5 inches long, a volcanic breccia if the fragments are larger.

Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass. These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff.

Tuff rock has geotechnical properties such as 18-25 kN/m3 of unit weight, 1.5 - 2.4 gr/cm3 of bulk density, 2.29 - 2.64 gr/cm3 of particle density, highly varied compressive strength depending on the degree of weathering, 0 - 1.45 MPa of cohesion, friction angle = 24° - 45° of friction angle, and 4% - 42% of porosity.
