Técnicas de beneficiamento do Quartzito Perla Venata

The Perla Venata, From the TAJ family, it is a quartzite mined in the Moraújo/Uruoca region - CE, Brazil. Its color is predominantly white to light cream, with veins ranging from light gray to light green, in patterns ranging from rectilinear to cloudy, giving the environment a sense of clarity and sophistication. Above all, it is a material that integrates with any furniture, regardless of color. It can be used in a wide variety of applications, such as gourmet islands, countertops, panels, interior floors, stairs, and tables, among others, demonstrating great versatility and adaptation to any project. Its grain size ranges from fine to coarse. This rock is composed of 100% quartz, which, combined with the geological conditions to which it has been subjected, makes it one of the hardest materials on the natural coverings market. In addition to its high hardness, it has very low porosity, which aids in specifications in high-use areas such as kitchen islands and countertops.

IMPORTANT INFORMATION TO THE MANUFACTURER (marbler)

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 Performance Model PS 5 – 350mm, Rocha Distribuidora model Normal diamond saw for Nano Glass.

Waterproofing in the cutting area: Even though it is a product with very low water absorption and few pores, we recommend waterproofing the cut edges of any piece.

Procedure: dry the edges immediately after cutting with a cloth or burlap and then with a hair dryer, followed by applying waterproofing using a brush.

Recommended waterproofing agents:

In Brazil = Rock Sheid Nano, from Chemistone or Nano Effect, from AKEMI

Abroad: Idea Gold, by Bellinzonni / Stain Proof, by Alicante / Proseal, by Tenax.

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

Brazil and abroad: Platinum, by AKEMI, / Titanium, by Tenax / or Spezial tak, by Bellinzonni

NOTE: It's important to strictly follow the manufacturer's recommended glue-catalyst ratio. Remember that in mild temperatures, the glue requires a little more time to cure. It's important to remove the protective screen at the cutting site to ensure full adhesion of the glue.

Laying parts on vertical panels: For installing vertical panels, bench tops, and baseboards, 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 installing the piece, we recommend waiting the manufacturer's suggested curing time before releasing the area for use. For mortar, always use white ACII, as per the brands suggested in the topics below.

Product recommendation: Hybrid glue AK 100 – AKEMI, TK PU40 white – AKEMI, PU 40 multi gray – Barone, PU 40 – Tekbond

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.

PU adhesive suggestions: AK 100 hybrid adhesive, from AKEMI / TK PU 40 white, from AKEMI / PU 40 multi gray from the manufacturer Barone / or PU 40, from Tekbond

Flooring installation: For laying indoor and outdoor floors, we recommend using mortar with high chemical adhesion and flexible properties.

Recommendation: Quartzo D mortar, from the manufacturer AKEMI / Flexible white ACIII cement mortar, from Quartzolit / or Votoran white ACIII internal/external Votomassa mortar.

For grouting, we recommend a waterproof and flexible product. Suggestions: AKEMI Premium Super Flexible Polymer Grout or Quartzolit epoxy grout.

Post-construction cleaning: 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 damages the waterproofing protection applied to the parts.

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

Post-construction protection: After post-construction cleaning, we recommend drying the entire area and applying a waterproofing layer to all surfaces, including the bonding edges and joints. This protects the material from any type of infiltration that may occur during daily use.

Waterproofing recommendation: Rock Protect, Chemistone / Idea Gold – Bellinzonni / or Nano Effect, by AKEMI,

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.
