Not sealing a stone countertop or floor tiles — which get the heaviest traffic and are the most susceptible to wear and tear — leaves the surface vulnerable to absorbing foreign substances, which can weaken the stone and potentially lead to the growth of bacteria.
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.
Because they are porous, natural stone tiles should be sealed with a penetrating sealer. Penetrating sealers, like Miracle Plus 511 Porous Plus, penetrate tiles to repel moisture from within, and prevent staining while still allowing vapors to escape.
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.
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.
First, companies can't seal grout until at least 48 to 72 hours after applying grout. By that time, bathroom remodelers typically have already cleaned up from the job and left your home. Secondly, some contractors use grout with additives that remove the necessity of grout sealer.
Using a sealer on natural stone helps to protect it against stains, while also giving you a little extra time to clean up any spills that may occur on your surface. It's important to note that while sealant does provide an extra barrier for your stone, everyday wear and tear will often still cause it to etch.
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.
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.
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.
If you purchase a high-quality slab countertop , you can feel confident that for potentially 50 years you will not need to replace it if you keep up with basic maintenance. The harder and less porous your natural stone the better the durability and life expectancy.
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.
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.
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.
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.
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.
The weight of the natural stone is heavier than artificial stone, and therefore its use in the building is time-consuming. Climate and environmental changes affect the texture of the rock and cause cracking, mildew, and dandruff on the surface.
When cleaning natural stones like marble, limestone, and onyx, you can't reach for your regular cleaners like white vinegar, lemon juice, bleach, or abrasive cleansers. These cleaners are too acidic for natural stone and can damage or etch the stone (although some can help remove rust from concrete).
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.
Apply a drop of water 1 inch in diameter to the stone surface. Allow the water to stand on the stone for 5-30 minutes. If the surface is unsealed, the water will absorb into the stone and darken the surface (absorption speed will depend on porosity of the stone).
Unfortunately, sealing natural stone is a relatively frequent chore. Depending on the type of stone, it could be required as often as every six months. If an impregnating sealant is used, it may only be required only every one to three years.
Maintenance is the Most Important Factor for Patio Longevity
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.
In conclusion the fading of stone is a real issue – it does happen. It must be remembered that it is mainly a problem in the limestone and marble (sedimentary and metamorphic) families as far as commercial dimensional stone is concerned.
Dry the surface off with a fresh microfiber cloth. This will take care of the bulk water. Depending on how porous the stone is, you'll need to let it dry for 24-72 hours after the deep clean.
Any type of material can be susceptible to cracking if not sealed correctly. This will keep moisture out to keep the grout from deteriorating. Allowing moisture into the grout can also lead to other problems such as mold, mildew or bacteria.
