Benefication techniques of Quartzite Nuage
The Nuage is identified in the reports as ornamental quartzite of metamorphic origin, originating from Paramirim, Bahia, Brazil. The petrographic analysis describes a massive and compact structure, granoblastic texture, medium-fine to fine granularity, and a predominantly quartzous composition (quartz indicated as 100% in the visual assessment). The sample exhibits a white to grayish-white color, as described in the laboratory reports.
IMPORTANT INFORMATION FOR THE MANUFACTURER (MARBLE WORKER)
Processing Data
The provided reports present results of technological and petrographic characterization, but do not establish marks of tools, adhesives, sealants, or specific manufacturing procedures for the Nuage. The guidelines below are general and should be validated by the technical responsible and the manufacturers of the inputs.
Cutting methodology: use diamond tools suitable for quartzite, with adequate cooling and dust control. Adjust speed, feed rate, and finish after testing on representative samples.
Edge protection: after cutting, clean and dry the surfaces before applying any compatible protective product, following the manufacturer's instructions.
Sticking together the pieces: select adhesive suitable for the rock, the application and the conditions of use. Respect the proportions, surface preparation and curing time indicated by the manufacturer.
IMPORTANT INFORMATION FOR THE INSTALLER
Vertical panels and rod-mounted benches: the fixing dimensions must be determined based on the weight, dimensions, substrate and safety conditions of the project. The selection of adhesives and anchors depends on the design.
Interior and exterior floors: assess the base, joints, movements, surface finish and slip resistance. Choose mortar and joint filler compatible with the application.
Cleaning and post-work protection: remove residues with water and a neutral cleaning product compatible. Avoid aggressive agents without prior testing and without the manufacturer's guidance.
IMPORTANT INFORMATION FOR END USERS (Attention: Family Members and Household Staff)
Care and maintenance guidelines for users over time:
- Reapply waterproofing every 12 months. These products are volatile and gradually evaporate over time, so periodic reapplication is necessary.
Recommended products: Rock Protect (Chemistone) / Idea Gold (Bellinzoni) / Nano Effect (AKEMI)
How to apply: Wash the surface thoroughly with water and neutral detergent, then dry with a towel. Spray 70% alcohol over the area and let it evaporate for 30 minutes. Finish drying with a hairdryer. Once the surface is clean and dry, spray the waterproofing product (using a regular spray bottle) evenly over the surface and spread it with a white cloth (to prevent color transfer). Let the product penetrate the stone pores for 12 hours. After that, your countertop or table is ready for use. These products are non-toxic.
This procedure ensures protection for your product and safety for your family.
- Surface protection guidelines:
- Do not use abrasive cleaners, as they can scratch the surface. Use a cloth or sponge with neutral soap.
- Do not cut food directly on the surface. Always use cutting boards.
- Do not place hot objects, such as pans, directly on the countertop. Natural stones are treated with resin, a polymer that can change color when exposed to intense heat, causing stains. Use wooden, rubber, plastic, or fabric trivets.
- Do not drag utensils across the surface. Small imperfections can cause scratches.
- Although the stone is dense, low-porosity, and protected by resin and waterproofing, it can absorb small amounts of liquids if left for long periods. Acidic and alkaline substances such as vinegar, lemon, coffee, wine, ketchup, mustard, mayonnaise, soft drinks, beetroot, and oils can cause stains if not removed promptly.
- Avoid impacts, excessive weight, or shocks on your stone. Despite its apparent robustness, natural stone has low cohesion between minerals and may develop cracks or fissures under physical stress or vibration. Do not use pestles directly on the surface unless protected by an impact absorber.
WITH THE RIGHT CARE, YOUR NATURAL STONE WILL LAST FOR GENERATIONS, PRESERVING THE SAME BEAUTY AND ELEGANCE AS THE DAY IT WAS INSTALLED.
