Natural stone tiles should be sealed regularly. They should be cleaned with products specifically formulated for cleaning natural stone. Never use bleach products on natural stone as they can discolor lighter stones. And when cleaning marble, never use a citrus-based product as it may etch the surface of the stone.
Because these stones have a high porosity, it's important to seal them about every six months and clean them with solutions specially designed for natural stone. This upkeep is essential to making sure your floors and countertops remain beautiful and functional for decades to come.
Quartz countertops are the easiest natural stone to take care of. They are engineered using ground stone and resin, so they don't require regular sealing they way most granite and marble countertops do. This stone is non-porous, so it does not easily stain or etch.
Water Will Discolor Them
Even something as simple as leaving a cold glass with condensation on your unsealed counters can change them. That's because water can penetrate the stone and leave behind water marks, permanently altering the appearance of your counters and potentially making them look dirty.
Over time, the water can weaken the stone, which can lead to fissures or cracks in the tile. Eventually, the water can penetrate to the subfloor, and once it does that, it can spread to other parts of your home. Water can trap bacteria in the tile, and it can contribute to the growth of mold and mildew in the subfloor.
Each type of stone is different, and they each need to be treated as such, but because all natural stone is porous, a penetrating and non-film forming sealer should be used so that it can penetrate deep within the stone and repel water from more than just the surface layer.
For lower traffic areas, like a kitchen backsplash or bathtub surround, you should re-seal your natural stone tiles every few years. Depending on the amount of traffic, some installers choose to re-seal their natural stone tiles every 18 months, while others choose to re-seal their tiles every 4 to 5 years.
A simple Water Drop Test is one of the easiest ways to examine whether or not your natural stone needs sealing! First, sprinkle a tablespoon of water on your stone. Leave the water on the surface for about 15 minutes. If the stone darkens or if the water is absorbed in less than 4 minutes, then resealing is needed.
Impregnating sealers (also known as penetrating sealers) are designed to penetrate below the surface and protect from within the stone while still allowing the miniscule pores of the stone to allow moisture vapor to escape.
Natural Stone, which includes marble, travertine, limestone, granite, onyx, quartzite, and is even part of some terrazzo contains pores. These pores are the openings in the stone that allow it to “breathe” and release moisture and gas. If your natural stone does not breathe it will eventually deteriorate and stain.
To keep it simple though, in areas with average wear, it's a good idea to reseal your tiles every 3 or 4 years. So to answer the question, you should seal your stone every 3-4 years.
Quartz is non-porous and therefore resistant to stains. Granite has low porosity and permeability. It is durable, but not as durable as quartz. Marble has higher porosity than granite and is particularly susceptible to damage from acidic substances such as vinegar.
Apply a thin coat of the appropriate sealer (there are different ones for polished natural stone tiles and for honed (matt) natural stone tiles) using a lint free cloth. Make sure the coat is even and all tiles are covered.
Natural stone, as beautiful and tough as it may be, is also somewhat fragile. While it defies the barriers of time and is extraordinarily durable, it requires a certain level of TLC to ensure it retains its original splendour.
Myth: Sealing will change the color of my stone.
Typically, impregnator sealers neither change the color of natural stone nor add shine. If you are sealing a polished limestone, travertine, marble, or granite, the impregnator will not change the color and will not add shine.
All natural stone tiles, whether polished, honed, or tumbled, are porous and require sealing before grouting. This essential step fills the pores with a protective sealer, preventing grout particles from causing a hazy surface appearance on your tiles.
A – On average, a stone sealer will last between 3-5 years before it will need to be reapplied. The quality of the sealer used and the porosity of the stone will all have an effect on just how long your sealer will last.
A matt stone sealer will not change the colour or appearance of a stone floor. A polished stone sealer will add a slight sheen to the surface of most stone tiles.
To protect a natural stone patio from harsh elements and chemicals, it's important that the patio is sealed as soon as possible. Once a patio has been sealed, other types of maintenance, such as regular cleanings, are very easy.
The first step is to check for any inclusion on the stone with your bare eyes. If you're unable to see any inclusions with your bare eyes, then use a magnifying glass of at least 10X magnification to find out if the gemstone contains any inclusions. If you found any, then they are real gemstones.
On average, the lifespan of natural stones, like marble and granite, can be well over 100 years. That's compared to ceramic tile with a life expectancy of 75 years.
The Difference Between Manufactured Stone and Natural Stone
Natural stone is heavier in weight, making it difficult to transport. Manufactured stone requires less installation time while also being cost-effective. Manufactured stone creates less waste than natural stone. Manufactured stone adheres to multiple surfaces.
Yes, your natural stone shower should always be sealed! To keep your shower in great shape – and keep mold and mildew at bay – we recommend having your shower sealed at least once a year. Instead of a topical sealant that may flake off or discolor the stone, choose a penetrating sealant.
Clean stone surfaces with a neutral cleaner, stone soap, or a mild liquid dishwashing detergent and warm water. Similar to any item cleaned in your home, an excessive concentration of cleaner or soap may leave a film and cause streaks.
ROUTINE CARE
Natural stone countertops and floors should be cleaned with neutral cleaners specifically designed for stone. These cleaners are concentrated pH neutral cleaners that will not affect existing sealers or other types of coatings. Stone cleaners should never contain acid or bleach.
