Product Overview
Terrazo Gris® Arterra® Series 13" x 24" x 2cm Matte Porcelain Pool Coping & Step Tread delivers modern terrazzo aesthetics, cool industrial-gray sophistication, and commercial-grade 2cm outdoor porcelain performance to pool perimeters, step treads, and outdoor coping caps. Part of MSI's Arterra® Premium Paver Collection, this specialized coping unit features a thick 20mm (2cm) solid porcelain body engineered specifically for exterior hardscaping.
The Terrazo Gris® colorway interprets classic Italian terrazzo stone with a neutral mid-gray field speckled with subtle, multi-tonal aggregate chips in white, light gray, and dark charcoal. Finished with a safety-first matte texture and a smooth finished coping edge, it provides exceptional underfoot slip resistance when wet, stays comfortably cool under direct sunlight, and eliminates the heavy maintenance required by traditional cementitious terrazzo.

Installation & Handling Guidelines
⚠️ IMPORTANT: 2CM EXTERIOR PORCELAIN COPING INSTALLATION PROTOCOL
-
Setting Mortar Selection: For pool bond beam installation, set coping units using a high-performance, polymer-modified Large & Heavy Tile (LFT) thin-set mortar specifically rated for continuous water immersion and exterior freeze-thaw cycles (ANSI A118.4 / ANSI A118.15).
-
100% Mortar Bed Coverage: Back-butter the rear of each 2cm coping piece to guarantee 100% mortar coverage without air pockets, preventing water from pooling underneath during freezing weather.
-
Pool Chemical & Salt Resistance: Because 2cm porcelain is non-porous, it is naturally impervious to salt-chlorine generator damage, chlorine bleaching, and calcium efflorescence.
-
Grout Selection: Fill joints using a high-performance exterior-grade flexible grout or epoxy grout designed to handle thermal expansion around pool perimeters.
Care & Maintenance
-
Routine Cleaning: Hose down or pressure wash periodically using fresh water or neutral pH outdoor cleaners.
-
Zero Sealing Required: Unlike natural stone or cement terrazzo, glazed 2cm porcelain repels liquids, oils, pool chemicals, and moss without needing sealers.
-
Stain & Algae Defense: Resistant to algae growth, leaf staining, and barbecue grease drips.
Design Profile
-
Aesthetic Inspiration: European Urban Resort, Modern Industrial, Retro Terrazzo, Coastal Contemporary.
-
Visual Advantage: Aggregated terrazzo flecks mask light outdoor dust and water spotting while adding energetic graphic movement to pool perimeters.
-
Complementary Finishes: Matches Terrazo Gris 24x24 or 24x48 2cm outdoor pavers; pairs seamlessly with matte black fixtures, natural teak outdoor furniture, and clean white plaster or dark blue pool finishes.
Frequently Asked Questions
Does Terrazo Gris® 2cm porcelain coping get hot in direct sunlight?
No. Porcelain pavers naturally absorb and retain significantly less heat than dark granite, dark concrete, or bluestone, making them comfortable for barefoot poolside walking.
Is 2cm porcelain coping safe for saltwater pools?
Yes! Impervious porcelain ($\le 0.5\%$ water absorption) is completely resistant to salt-chlorine generators, salt crystallization damage, and acidic pool chemicals.
Do I need to seal Terrazo Gris® Arterra® porcelain coping?
No. Arterra® 2cm porcelain is completely non-porous and never requires impregnating sealers or topical coatings.
