Materials

Color Layer: Portland cement, micron size marble dust, marble chips (optional), additive, special chemicals, iron oxide color pigments

Back Layer: Gray Portland cement, granular sand, chemicals

Product Components

Color Layer: This layer bonded to the tile body with 1,700 PSI (120 bar) mechanical pressure is 3-4 mm +/- thick. Consists of PC 52,5 white Portland cement, marble dust, and mineral color pigments (iron oxides and organic).

Tile Body: 14 mm thick and consists of following: PC 42,5 R gray Portland cement and granulometric sand

Sizes: 20 cm x 20 cm x 1.80 cm +/- (8 “x 8” x 5,6/8 “)

· 1.5 kg / tile (3.37 lbs) +/-

· 37,5 kg / m2 (7,35 lbs / sqf) +/-

E1.1.3. Friction Coefficient

Dry / Polished:  0.83 Dry / Non-polished: 0.88

Wet / Polished:  0.68 Wet/ Non-polished: 0.92

Scratch Resistance

Scratch Resistance of encaustic tiles of Karo Istanbul collection is approx. 3 – 4 according to MOHS scale. Similar to scratch resistance of black marble.

E1.1.5. Freeze / Thaw resistance

Just as concrete, unprotected encaustic tiles are not resistance to freeze/thaw cycles.  It must be protected with sealants penetrable into tile body or with an acrylic-based second layer. This will be needed more in the outdoors and locations liable to frost risk.

Acid Resistance

Encaustic tiles are not acid-resistant. Therefore they must be cleaned with neutral cleaners with a pH of around 7.

Use in the wet areas

For showers, spa and pools, an effective and high-quality sealant must be used. The water absorption of encaustic tiles is at the level of 9.5% – 10.5%. Therefore, signs of algae growth may be seen on the color layer in time.
