Introducing the StoneCare4U Essential Satin Finish Sandstone Sealer 5L for professional and high-quality performance on natural sandstone surfaces. This durable and quick-drying formula provides a stain-resistant coating that intensifies natural colours and offers excellent protection against stains. It is also suitable for porous natural stones like slate and limestone. To apply the sealer, start by removing any loose debris from the surface and ensuring you have the necessary safety wear, including gloves, protective eyewear, a face mask, and suitable clothing. Allow the surface to dry completely for at least 72 hours with clear and dry weather conditions. The recommended application temperature range is between 15 to 23 degrees Celsius. Apply the sealer thinly and evenly using a low-pressure sprayer, micro-fibre mop, paintbrush, or soft cloth. Take care to avoid leaving application marks or allowing the product to puddle on the surface. Do not dilute the sealer. Allow 45 to 60 minutes for the first coat to dry before applying a second coat. Repeat the same process, applying the product in the opposite direction to achieve a consistent finish. If desired, additional coats can be applied to achieve a glossy finish. Please note that the sealer may alter the colour and appearance of some surfaces, so it is advisable to test the product in an inconspicuous area before full application. Any surfaces that should not be sealed should be protected with masking material. Lastly, please be aware that this product is not suitable for Kandla Grey (mid and light-grey) sandstone. Pack of 3.
