Protect stone surfaces from damage with the StoneCare4U Essential Masonry Sealer 25L - specifically designed for outdoor use on masonry, brick, and porous vertical stone surfaces. It contains resins that effectively seal and protect these surfaces, providing excellent water repellence and helping to prevent efflorescence, green growth, and algae growth. This sealer offers long-lasting protection and requires minimal maintenance once applied. It is a convenient and efficient solution for sealing masonry, blockwork, and brickwork, and it can be applied directly from the bottle. To apply the sealer, it is important to prepare the work surface by removing any loose debris. Additionally, ensure that you have the necessary safety wear, including gloves, suitable protective eyewear, an FFP3 class mask, and appropriate clothing. The application temperature should not be lower than 8 degrees Celsius. Before using the sealer, it is recommended to perform a small test application in an inconspicuous area to determine its suitability and effectiveness for your specific surface. How to apply: Before applying the sealer, make sure that the surface is completely clean and dry. You can use a low-pressure sprayer, roller, natural fibre brush, or sponge to apply the product. Apply the first coat generously, ensuring that the sealer penetrates the surface as much as possible. Once the first coat is applied, proceed to apply a second coat before the first coat has dried to ensure complete coverage. It is important not to dilute the sealer. The surface should be dry within 45 to 60 minutes after application. It is crucial to note that if rain is forecasted or starts during the application process, you should immediately stop the treatment and cover the freshly impregnated areas. The surface needs to remain completely dry for the first 6 hours after application. Please be aware that the sealer may subtly enhance the natural colour of the stone surface. Therefore, it is always recommended to test the product in an inconspicuous area before applying it to the entire surface. Additionally, any surfaces that are not intended to be sealed should be protected with masking material.
