SANDSTONE CLEANER: A cleaning agent for all types of sandstone, limestone, granite, river rock, and slate. It is specifically designed for use on fences, patios, sidewalks, driveways, and parking lots. It effectively removes dark deposits and dirt accumulated during everyday use. It refreshes the appearance of stone surfaces. Suitable for hand washing, high-pressure cleaners, and cleaning machines. Unlike acidic cleaners, it is safe for stone and vegetation – biodegradable and solvent-free. SANDSTONE IMPREGNATOR: A waterproofing agent for all types of sandstone. It works perfectly on substrates, walls, and facades. It chemically protects the entire stone structure at a nanometric level, protecting it from water and salt ingress, dirt, and stains. It maintains the stone's natural vapor permeability. It provides protection against the negative effects of external factors, including UV radiation. It improves durability and strengthens the material's structure. The product does not alter the natural appearance of the material, nor does it grease or darken it. It's worth using SPECIALCHEM Sandstone Basic impregnation for several reasons: Protection against contamination: Impregnating sandstone can provide protection against contaminants such as chemicals, plants, and mold. The impregnation coating prevents contaminants from penetrating the stone, making it easier to keep the sandstone surface clean and preventing degradation. Protection against moisture: Sandstone is porous and can easily absorb moisture. Impregnating sandstone creates a protective barrier that prevents water, salt, dirt, and other liquids from penetrating the stone. This makes impregnated sandstone more resistant to erosion, allowing it to better maintain its strength and aesthetic appeal over time. Aesthetics: Impregnated sandstone can also improve its aesthetic appearance. The impregnation coating can give the stone a more uniform color, enhance its color and texture, and protect it from fading or graying. Sealed sandstone has a fresh and attractive appearance, which can further enhance the charm of a building or architectural element made of this stone. Increased durability: Sealing sandstone can significantly increase its durability. When stone is exposed to atmospheric factors such as frost, rain, and UV radiation, surface degradation can occur. Sealing creates a protective layer that strengthens the sandstone's structure and protects it from these elements. This makes sealed sandstone more resistant to cracking, flaking, and erosion. Aesthetics: Sealed sandstone can also improve its aesthetic appearance. A sealing coating can give the stone a more uniform color, enhance its color and texture, and protect it from fading or graying.
