Técnicas de beneficiamento do Quartzito White Macaubas
The White Macaubas is a quartzite mined in Diamantina, MG, Brazil; predominantly white to slightly cream-colored, with light gray streaks, designed in curved shapes, giving smoothness to its exotic rock characteristics. It has medium to fine grain. This rock can be used in a wide variety of applications, such as gourmet islands, countertops, panels, indoor and outdoor flooring, stairs, bathrooms, and tables, among other uses, being a very versatile material that adapts well to any project. It is composed of 99% quartz and 1% Sericite and opaque minerals. Its grain size ranges from 0.2 to 2.2 mm, which provides low porosity, facilitating specification in all environments.
IMPORTANT INFORMATION FOR THE MANUFACTURER (MARBLE WORKER)
Beneficiation data
The choice of input materials for manufacturing this product directly affects its production cost and the final quality of the manufactured 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 input materials required for successful processing:
Cutting methodology: To ensure the quality of cuts and grinding, we recommend discs, hole saws, and diamond grinding wheels made of soft metal alloy. In Brazil, we recommend Performance Modelo tools. PS32M or Pyramid model PR 30.
Waterproofing in the cutting area: When the cuts are made, the sides are left unprotected, requiring waterproofing before finishing. For this process to be fully effective, the area must be clean (use 70% alcohol) and completely dry (dry with a heat gun or flamethrower). Then, using a brush, apply a layer of waterproofing over the entire length of the cut. It is important to follow the manufacturer's usage recommendations before beginning the gluing and/or finishing process.
Recommended waterproofing agents:
In Brazil = Rock Sheid Nano, by Chemistone / Nano Effect, by AKEMI / or Idea Gold, by Bellinzonni.
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 is important to strictly follow the proportion of glue + catalyst recommended by the manufacturers.
IMPORTANT INFORMATION FOR THE INSTALLER
Laying parts on vertical panels: For installing vertical panels, bench wheels and footrests, we recommend using Polyurethane glue – PU 40.
Important ensure the wall surface is level and free of dust and other dirt. After applying PU 40 and installing the piece on the wall, we recommend waiting the manufacturer's suggested curing time before releasing the area for use.
Suggestions of some PU brands: AK 100 hybrid glue, from AKEMI / TK PU40 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.
For grouting, we recommend a waterproof and flexible product.
Recommendation for laying: Quartzo D mortar, by AKEMI / Flexible white ACIII cement mortar, by Quartzolit / or Votoran white ACIII internal/external Votomassa mortar.
For Grout: Premium Super flexible polymer, from AKEMI or Quartzolit epoxy grout.
Post-construction cleaning and protection: All post-construction cleaning must be carried out using water and neutral detergent to remove residue; NOT the use of acidic detergents, acetone or any polymerase is permitted. These types of products damage 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 cleaning, we recommend drying the entire area and applying a waterproofing layer to all surfaces, including the bonding edges and grout lines. This protects the material from any type of infiltration that may occur during daily use.
Waterproofing recommendations: Rock Protect, by Chemistone / Idea Gold, by 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.
