The Miracle Sealants 511 Impregnator is a versatile grout sealer designed for both indoor and outdoor use on various surfaces like grout, ceramic, stone, and tile. One of its strong points is its broad water and stain resistance, thanks to an oil and water-resistant formula that creates an invisible barrier to protect surfaces from moisture and stains. This makes it a good choice for areas prone to spills or dampness, such as kitchens and bathrooms. It covers a large area—up to 4,000 square feet per gallon—so it’s economical if you have a big project.

Application is straightforward and user-friendly, with the added benefit that it won’t yellow over time or affect food prep areas, which is a plus for safety and appearance. The product is also UV transparent and weather-resistant, so it holds up well outdoors and in sunlight. However, while it is water-resistant, it may not be fully waterproof, so for areas with heavy water exposure, you might want to consider a stronger option.

Because it’s solvent-based, the product may have a stronger odor and require careful ventilation during use compared to water-based sealers.
