Water Resistance
Users appreciate its effectiveness but note that even sealed surfaces need immediate water cleanup to prevent absorption and potential stains.
Stain Resistance
Seals counters thoroughly, allowing even enriched dough and laminate croissant dough to be rolled out without grease stains on white stone.
Ease of Application
For small countertops, the application is easy and quick to clean up, but larger countertops pose a challenge due to its runny consistency and quick curing.
Drying Time
After application, the sealer dried evenly with no blemishes or cloudiness, leaving a non-glossy finish that maintained the natural look of the stone.
Durability
Despite needing reapplication every 3 months, especially around sink areas, it remains one of the best stone protectors, outperforming other brands like Sen-guard and Granite Shield.

Buying Guide for the Best Grout Sealers

Choosing the right grout sealer is essential for maintaining the appearance and longevity of your tiled surfaces. Grout sealer helps protect the grout from stains, moisture, and mildew, ensuring that your tiles look great and last longer. When selecting a grout sealer, it's important to consider several key specifications to ensure you pick the best one for your needs. Here are the key specs to look out for and how to navigate them.
Type of SealerGrout sealers come in two main types: penetrating sealers and membrane-forming sealers. Penetrating sealers absorb into the grout and protect it from within, making them ideal for areas exposed to moisture, like bathrooms and kitchens. Membrane-forming sealers create a protective layer on the surface of the grout, which can be effective in areas with less moisture exposure. Choose a penetrating sealer for high-moisture areas and a membrane-forming sealer for low-moisture areas.
Water ResistanceWater resistance is crucial for grout sealers, especially in areas like showers, bathrooms, and kitchens where moisture is prevalent. High water resistance prevents water from seeping into the grout, reducing the risk of mold and mildew growth. Look for sealers that specifically mention high water resistance if you are sealing grout in wet areas. For dry areas, water resistance is less critical, but still beneficial for overall protection.
Stain ResistanceStain resistance is important to keep your grout looking clean and new. A good grout sealer will repel stains from spills, dirt, and other contaminants. Sealers with high stain resistance are ideal for kitchen backsplashes, countertops, and floors where spills are common. If you are sealing grout in a high-traffic area or a place prone to spills, prioritize a sealer with strong stain resistance.
Ease of ApplicationThe ease of application can vary between grout sealers. Some sealers come in spray bottles for easy application, while others require a brush or roller. Consider your comfort level with applying the sealer and the size of the area you need to cover. For small areas or touch-ups, a spray sealer might be more convenient. For larger areas, a brush or roller application might be more efficient.
Drying TimeDrying time is the amount of time it takes for the sealer to cure and be ready for use. Faster drying times are convenient if you need to use the area soon after sealing. However, some sealers with longer drying times may offer more durable protection. Consider your schedule and how quickly you need the area to be functional when choosing a sealer with an appropriate drying time.
DurabilityDurability refers to how long the sealer will last before needing reapplication. High-quality sealers can last several years, while others may need to be reapplied more frequently. If you want a low-maintenance option, look for a sealer with a longer lifespan. For areas with heavy use or exposure to harsh conditions, a more durable sealer is essential to ensure long-lasting protection.
