How to choose barbecue grill covering

The barbecue grill is one of the highlights in external or internal areas of a residence. For being an attractive element while composing as the center piece of decoration, the barbecue grill deserves a special attention from architects.

Granite is an excellent option of barbecue grill covering, it is a material with high resistance to the heat from fire and fat. Even though the material has high resistance, we advise to clean the granite as soon as possible when some kind of product or fat falls on it. In addition to that, this natural stone provides sophistication and elegance to the environment.

Should I use light or dark color in barbecue grill covering? 

Although the granite is a resistant material for the barbecue grill, it is recommended to use dark shades, because they are more efficient against stains from agents like fats and drinks. However, if you want to use light colors of granite, it is indicated to waterproof the stone and do maintenance periodically.


Another advantage of barbecue grill covering with granite is the simplicity of cleaning due to its smooth and uniform surface. Neutral detergent and wet cloth are enough to clean. It’s worth pointing out that abrasive products as steel wool are not recommended because it makes the stone lose its natural shine throughout time.

Granite colors 

It is necessary to choose carefully the color of granite so that there is harmony with the environment. When it comes to barbecue grill covering, the black and brown colors are the most popular. Beyond conveying elegance, these colors match with all colors and forms of other decorations from the environment.

How to preserve marbles and granites?

Marbles and granites are elegant, resistant and timeless in any type of environment. These characteristics make the stone often used in architectural and decoration projects, as facades, columns, stairs, floors, fireplaces and countertops. Due to the broad use, they are exposed to different types of substances, which can compromise the useful life and surface of the stone. Therefore, some cares are necessary for the correct conservation and maintenance of marbles and granites.


In certain cases it is recommended to do the waterproofing of the stones to avoid the absorption by the spill of liquids that can cause stains. This practice should be done annually, prolonging its conservation.


This point deserves attention! The execution and installation of projects with marbles and granites should be done by companies or capable professionals. Installation mistakes can compromise the design and durability of the stones in some cases, requiring replacement of parts due to irreversible damages. Besides knowing to work with each stone and their particularities, these companies can also guide the customer about maintenance and protection for each type of stone. The installation of the stones should be the last step of the project, avoiding people’s movement with residues in shoes that may cause scratches on surfaces.

Stains and scratches

Marbles and granites are porous materials and require special attention with liquids on their surface. Liquids as oil, fat, coffee, wine or even water in abundance can compromise irreversible stains and damage the brightness of the stones. In case of a spill, the surface should be cleaned as soon as possible.

In the case of kitchen countertops, avoid using the stones as a cutting board, because it can cause scratches and cuttings. You should also avoid leaving aluminum objects, iron and steel on the surface, because with the passage of time they can rust and spot the material.

Correct cleaning of marbles and granites

Daily cleaning

The daily cleaning can be done just with clean cloth, water and neutral detergent. Then, finalize the process drying the surface with a soft cloth.

Avoid chemical and abrasive products

NEVER clean marbles and granites with bleach, kerosene, solvent, alkaline detergent or any other abrasive chemical product. These products are highly harmful to the maintenance of the stones, because they can cause stains and scratches.

Following these orientations you can keep the natural and elegant appearance of the stones for more time. Check out the marbles and granites from PR Marble and Granite own quarries.

How the granite and marble extraction is done?

Marbles and granites are stones formed inside the earth through the cooling of the magma. Inside the earth, after the mantle, is located a deep layer of melted stone composed by reactions of radioactive elements, which ends up suffering a process of decomposition. The decaying material releases an intense heat wave that merges the stones around. The geological events, as the movement of plates or pressure, make the stones be pushed to the surface. When the rocks reach the surface occurs a cooling that originates igneous rocks, as granite and marble.

The extraction process of granite and marble starts in quarries. Quarries are natural reserves in rocky mountains, a place where the stones are in their natural aspect. For a successful extraction, a professional team and appropriate equipment are required, because it is a delicate activity and requires safety and preservation of the stones at the time of extraction.

To slice a stone in a smaller size, a variety of tools are used, between them: diamond wire machine, hidrobags, stone crusher, diamond drill, among others. The first piece of the stone is called stand or board, which has an approximate measure of 39″ 4.44′ x 19″ 8.22′ x 5″ 10.86′. After the removal of the stand, it will be analyzed by a trained professional that will delimit this stone in many areas for a new clipping, where it will be produced blocks (small cubes of stones with an approximate measure of 9” 10.1’ x 5” 10,8’ x 5” 10,8’). To move the blocks inside de quarries, from the place of extraction to the storage yard, big tractors as loader machines are used.

After this stage, the materials are stored in big trucks adapted for heavy loads and transported with destination to the industry where the blocks are transformed into sheets.

The sheets can be produced in the following finishes: polished (with brightness), levigate (without brightness) and plastered (without brightness). After the process of extraction and industrialization, the granite and marble will be ready to be market by stores that will execute projects of sinks, stairs, countertops, columns, fireplaces and as far as the creativity goes.

Como conservar mármores e granitos?

Mármores e granitos são materiais requintados, resistentes e atemporais em qualquer tipo de ambiente. Essas características tornam as rochas muito utilizadas em projetos arquitetônicos e de decoração, como fachadas, colunas, escadas, pisos, lareiras e bancadas. Devido a ampla utilização, ficam expostos aos mais diversos tipos de substâncias, o que pode comprometer sua vida útil e estética. Portanto, tornam-se necessários alguns cuidados para a correta conservação e manutenção dos mármores e granitos.


Em certos casos é recomendável realizar a impermeabilização das pedras, evitando a absorção pelo derramamento de líquidos que possam causar manchas. Em média essa prática deve ser feita anualmente, prolongando sua conservação.


Este ponto merece grande atenção! A execução e instalação dos projetos com mármores e granitos devem ser feitas por empresas/profissionais capacitados, pois alguns erros de instalação comprometem o projeto e a durabilidade das pedras, em alguns casos sendo necessária a substituição das peças devido a danos irreversíveis. Além de saberem trabalhar com cada tipo de pedra e suas particularidades, as empresas especializadas também saberão orientar o cliente quanto a manutenção e proteção para cada tipo de pedra.

A instalação das pedras deve ser a última fase do projeto, evitando circulação de pessoas com resíduos nos sapatos que podem causar riscos nas superfícies.

Manchas e riscos

Mármores e granitos são materiais porosos e exigem atenção especial com líquidos em sua superfície. Líquidos como o óleo, gordura, café, vinho ou até mesmo água em abundância podem ocasionar manchas irreversíveis e prejudicar o brilho das pedras. Caso haja um derramamento, a superfície deve ser higienizada o mais rápido possível.

No caso de bancadas para cozinha, evite usar as rochas como tábua para cortar alimentos, pois isso ocasiona riscos e cortes. Evite também deixar objetos de alumínio, ferro ou aço parados na superfície, pois ao longo do tempo eles podem enferrujar e manchar o material.

Limpeza: como conservar mármores e granitos

Limpeza diária

A limpeza diária pode ser realizada apenas com uso de um pano limpo, água e detergente neutro. Em seguida, finalize o processo de limpeza secando a superfície com um pano macio.

Evite produtos químicos abrasivos

Nunca faça a limpeza dos mármores e granitos com água sanitária, querosenes, sapólios, solventes, detergente alcalino ou qualquer outro produto químico abrasivo. Esses produtos são altamente nocivos à manutenção das rochas, pois podem ocasionar manchas e riscos.

Seguindo essas orientações você mantém o aspecto natural e elegante das rochas por muito mais tempo. Conheça os mármores e granitos oriundos de jazidas próprias da PR Grupo Paraná!

Como é feita a extração do granito e mármore?

Os mármores e granitos são rochas formadas dentro da terra por meio do esfriamento do magma. No interior da terra, após uma camada de manto, localiza-se uma profunda camada de rocha derretida formada através de reações dos elementos radioativos, que acaba por sofrer um processo de decomposição. O material em decomposição libera uma intensa onda de calor que funde as rochas ao redor. Os acontecimentos geológicos, como o movimento de placas ou pressão, fazem com que essas rochas sejam empurradas para a superfície. Quando as rochas chegam à superfície da terra ocorre um resfriamento, originando assim rochas ígneas internas, entre elas o granito e mármore.

O processo de extração do granito e mármore tem início nas jazidas. As jazidas são reservas naturais em grandes montanhas rochosas, local onde as pedras estão em seu estado natural. Para o sucesso da extração, são necessários equipamentos apropriados e equipe profissional bem preparada, pois a atividade é delicada e requer segurança de pessoal e preservação das pedras no momento da extração.

Para se “fatiar” a rocha em um tamanho menor, diversas são as ferramentas utilizadas dentre elas: máquinas de fio diamantado, hidrobags, marteletes, brocas diamantadas, dentre outros.

O primeiro pedaço de rocha é chamado de bancada ou prancha, o qual tem uma medida aproximada de 12 metros de comprimento X 6m de altura X 1,80 de largura. Após retirada a bancada, a mesma será analisada por um profissional treinado que irá demarcar essa rocha em várias áreas para um novo recorte, onde desse recorte serão produzidos os blocos (cubos menores de pedras de aproximadamente 3 m x 1,8 m x 1,8 m). Para movimentar os blocos dentro das jazidas, do local da extração até o pátio de armazenagem, grandes tratores como maquinas pá carregadeiras são usadas.

Após essa etapa, os materiais são armazenados em grandes caminhões adaptados para cargas pesadas e transportados com destino a indústria onde lá esses blocos serão transformados em chapas.

As chapas podem ser produzidas nos seguintes acabamentos: Polido (com brilho), levigado (sem brilho) e escovado (sem brilho). Após passado pelo processo de extração e industrialização o granito e mármore estarão prontos para ser comercializado por marmorarias que irão executar os projetos de pias, escadas, balcões, colunas, lareiras e até onde a criatividade permitir.
