Matarazzo processing techniques

Matarazzo is a rock mined in Paraná, near Curitiba, Brazil. It is a carbonate metamorphic rock composed of 95% dolomite, 5% quartz, and traces of talc, muscovite, chlorite, and magnesite, with fine-grained crystals. Its intense metamorphism resulted in significant compaction and, consequently, low porosity. Carbonate rocks are characterized by low porosity, a hardness of between 3 and 3.5 on the Mohs scale, and low resistance to chemical attack by acids such as citric acid. Aesthetically, they blend well with any environment, including bathrooms, countertops, interior stairs, niches, and more. For installation in high-use areas, we recommend installing the product with a brushed finish to avoid loss of shine.

INFORMATION TO THE MANUFACTURER (marbler)

Note: Although this material has metamorphic rock characteristics, it cannot be compared to quartzite in the specifications due to its lower hardness. However, when preparing the cut, we must use the same tools as for cutting quartzite. This material has small veins in the slab that can open when subjected to force during the cutting process in the marble shop.

Beneficiation data

The correct selection of inputs for manufacturing this product directly impacts production costs and the final quality of the finished part. Assuming the equipment used is in good condition, the cooling system water is clean, and there is no solid waste circulating through it, the following are recommendations for the inputs required for successful processing:

Cutting methodology: to ensure the quality of cuts and grinding, we recommend diamond discs, saws, cups and grinding wheels made of soft metal alloy. In Brazil, we recommend tools from Pyramid model PR30 (same used in Dekton), Performance Model PS 32 – 350mm,

Waterproofing After gluing and finishing the pieces, we recommend applying a water-repellent film to protect the surface from stains such as juices, oils, ketchup, and others. We perform waterproofing as follows: With the surface clean and dry, and using a brush, apply a layer of waterproofing to all surfaces (tops, skirts, wheels, countertops, sills, and windowsills).

It is important to follow the manufacturer's usage recommendations before starting the gluing and/or finishing process.

Recommended products:

In Brazil = Rock Shield Nano – Chemistone, Nano Effect – AKEMI, Idea Gold – Bellinzonni.

Abroad: Idea Gold – Bellinzoni, Stain Proof – Alicante, Proseal – Tenax.

Gluing the pieces: To ensure the quality of the gluing of the pieces, we recommend the following glues:

Brazil and abroad: Platinum – AKEMI, Titanium – Tenax, Spezial tak – BellinzonniI

NOTE: It is important to strictly follow the proportion of glue + catalyst recommended by the manufacturers. In this case, we recommend using a pigment to match the color pattern of the material.

IMPORTANT INFORMATION FOR THE INSTALLER

Laying parts on vertical panels: For installing vertical panels, bench tops, and skirting boards, we recommend using PU 40 polyurethane adhesive. Remember that the wall surface must be level and free of dust and other dirt. After applying PU 40 and gluing the pieces, we recommend waiting the manufacturer's suggested curing time before releasing the area for use.

Product recommendation: Hybrid adhesive AK 100 – AKEMI / TK PU40 gray or black – AKEMI / PU 40 multi gray – Barone / PU 40 – Tekbond

Installation on sink countertops: Given this material's low flexural strength, we recommend using support points every 60 cm on countertops. For cantilevered countertops, we recommend supporting the piece on a metal support and securing it with black or gray PU 40 polyurethane glue.

Post-construction cleaning and protection: All post-construction cleaning must be carried out using water and neutral detergent to remove residue; the use of acidic detergents is not permitted, as this type of detergent damages the waterproofing protection applied to the parts.

Recommendation: Quartzolit post-construction cleaner / Post-construction floor cleaner detergent, by Bellinzonni / PCS Alcalino, by the manufacturer Piso Clean / or Basic Cleaner detergent – AKEMI brand

IMPORTANT INFORMATION TO THE END USER (Attention family and domestic workers).

Precautions to be taken by users over time:

Reapply waterproofing every 12 months. Waterproofing agents are volatile substances and evaporate over time. Therefore, temporary reapplications of the product are recommended.

Recommended products: Rock Protect, by Chemistone / Idea Gold, by Bellinzonni / or Nano Effect, by Akemi.

How to apply: Wash the surface thoroughly with water and detergent and dry with a towel. Spray and spread 70% alcohol over the area, letting it evaporate for half an hour. Finish drying with a hairdryer. Once the surface is clean and dry, spray the waterproofing agent (using a standard spray bottle used for water or alcohol) over the entire surface, then spread it with a white cloth (to prevent the dye from coming off the fabric) and wait 12 hours for the waterproofing agent to fully penetrate the stone's pores. It's ready, and you can now use your table or countertop. Waterproofing products are non-toxic.

This procedure guarantees protection for your product and safety for your family's health.

Protection against surface damage:
Don't use abrasive products to clean your countertop. This can scratch the surface. Use a cloth or sponge with mild soap.
Do not cut products with a knife directly on the surface – use cutting boards for this.
Avoid placing hot objects, such as pans, on the countertop – the processing of natural stone uses resin on the surface. Resin is a polymer that alters with intense heat and can change color, causing unwanted stains. Use a wood, rubber, plastic, or fabric protector to prevent direct contact between the hot pan and the surface of your countertop or table.
Don't drag utensils across the surface. They may have grooves, imperfections that can scratch your countertop.
Even though it's a dense product with little porosity and protected by resin and waterproofing, natural stone can absorb small amounts of liquids that remain on its surface for a long time. Some of these liquids, especially acids and alkalines, can cause stains when absorbed. Among these, we highlight: vinegar, lemon, coffee, wine, ketchup, mustard, mayonnaise, soda, beetroot, and oils. It's okay if any of these products are spilled or exposed on your countertop or table, but we recommend not waiting too long to remove them.
Avoid blows, knocks, excessive weight, or impacts on your natural stone. Despite its apparent robustness, rocks have little bonding between their elements and can crack or fissure if subjected to physical shock or vibration. Avoid using spice grinders directly on the surface, unless it is well protected by an impact absorber.

With the right care, your natural stone will last for generations, maintaining the same beauty and exuberance as when it was installed.
