Stone processing technology - Stone sealing technology

Shanghai Jiani Material Technology Co., Ltd. is a professional company specializing in the production of stone tiles.

All natural stone contains microscopic pores, which necessitates stone sealing treatment. Granite boasts the densest structure among stone varieties and requires re-sealing every 2 to 4 years. It is recommended to use non-acidic cleaners. Although ammonia and bleach do not harm granite, they accelerate the deterioration of sealers. pH-neutral stone cleaners available at grocery and home improvement stores deliver optimal cleaning results.

Calcium-based stones, including marble, travertine and onyx, feature less compact structures and demand specialized maintenance. Due to their chemical composition, acidic cleaners, food and beverages will corrode their surfaces, causing etching marks that dull the original glossy finish. Fortunately, nearly all natural stone can be professionally restored to its original condition. Natural stone surfaces should be sealed with stone sealer on a regular basis.

How to Check If Resealing Is Needed

A simple water bead test can tell you the condition of the sealer. Place a glass of ice water on the stone countertop and wait for condensation to form on the glass exterior. Wipe the countertop dry with a cloth afterward. If no dark ring remains on the stone surface, the sealer is still intact. If a dull dark ring is left where the glass sat, the sealer has worn off and re-sealing is required. This test is quick and straightforward.

Natural stone and engineered stone are premium countertop materials widely used on the market. Always keep stone countertops free of dust and sand. Sand grains are essentially tiny granite particles that scratch stone surfaces through friction. Avoid placing heavy crates on countertops or dragging heavy objects across them. Sand trapped underneath dragged boxes will leave permanent scratches, whose repair comes with high costs and great inconvenience.

Granite and engineered stone feature excellent heat resistance. Hot cookware can be placed directly on their surfaces without scalding or discoloration — an advantage unmatched by other solid surface materials.
