Paramount Quartzite Beneficiation Techniques

The Paramount Quartzite is a exotic metamorphic quartzite, with a generally gray background light  and linear and wavy veins in shades of gold, brown, gray and rust, creating a sophisticated effect that is highly valued in the international market. It is considered a premium material, comparable to quartzites such as Perla Venata and Taj Mahal, but with its own identity due to its remarkable movement.

Average Mineralogical Composition

• Quartz: 80–90%
• Feldspar: 5–10%
• Accessory minerals (micas, iron oxides, tourmaline, garnet): up to 10%

Properties

• Hardness: 7–7.5 Mohs → extremely scratch resistant.
• Water absorption: 0.2% – 0.4% → low.
• Compressive strength: 180–220 MPa.
• Chemical resistance: high, not attacked by household acids.

Paramount combines high-standard durability and aesthetics, being ideal for luxury and heavy-use environments.

 INFORMATION TO THE MANUFACTURER (Marbler)

Recommended finishes

• Polish: highlights the shine of the golden veins and the contrast of the light background.
• Brushed (Leather): satin finish, widely used in kitchens and gourmet areas.
• Levigated: elegant matte, excellent for modern interior floors.
• Flamed + Brushed: ideal for outdoor floors and non-slip areas.

Processing and Cutting

• Because it is a high-hardness quartzite, it requires high-performance diamond tools (e.g.: Diapar DP-Quartz discs or similar).
• The movement of the veins can create areas of greater weakness → it is recommended to reinforce sheets with epoxy resin before polishing.
• Accepts straight cuts and special moldings without additional technical difficulty.

Waterproofing

Despite low absorption, preventive waterproofing is recommended on countertops and high-use areas.

Recommended products:

• Brazil: Rock Protect – Chemistone / Nano Effect – AKEMI / Idea Gold – Bellinzoni
• Abroad: Proseal – Tenax / Stain Proof – Dry Treat / Idea Gold – Bellinzoni

Procedure:

• Apply to a clean, dry surface with a brush or roller.
• Waterproof edges and cuts before installation.
• Reapply every 2–3 years in high-use areas.

Gluing the Parts

• Use high-adhesion epoxy/polyester glues (Tenax Fix Top, Bellinzoni Blitz Mastique, Argacon Marmofix).
• Pigment glues in light or beige/gold tones depending on the batch.

Settlement

• Benches: support every 60 cm on metal corners, gluing with white PU40.
• Indoor/outdoor floors: white ACIII adhesive mortar.
• Flexible grout and final application of water repellent after the mortar has cured.
