MACt Pre-Seal (1L)
MACt Pre-Seal is a type of sealer that is specifically designed to be used before applying a Mact Seal to protect concrete basins, baths, and benchtops. Its primary purpose is to improve the protection of the surface against water and stains, making it ideal for use in areas where water exposure is high. In addition, MACt Pre-Seal can help to increase abrasion resistance and shine on polished surfaces when burnished. It is also UV stable and will not yellow over time, making it a long-lasting solution for concrete surfaces.
One of the main reasons why concrete surfaces are prone to staining is due to their porous nature. Uncoated concrete is particularly susceptible to staining, as the surface is never perfect, even after being refined through the processing stage. Glass fiber reinforced concrete (GFRC) does not produce a microscopic flat surface, and the sanding and acid washing process often leaves scratches and cuts in the surface that are so small they cannot be seen. When combined with micro cracks, this creates a significant opening for materials to seep into the concrete and create stains. Once a stain has penetrated the surface, it is incredibly difficult to remove it without damaging the surface of the concrete.
To address this issue, MACt Pre-Seal works by changing the surface of the concrete to make it less likely for stains to stick. This is achieved through the concept of surface energy – the lower the surface energy, the less likely contaminants and stains are to adhere to it. Most sealers are organic and hydrocarbon-based, which can actually increase the chances of staining. In contrast, using a silicone-based sealer like MACt Pre-Seal can lower the surface energy, making it more difficult for hydrocarbons to stick and creating a stain-repellent surface.
In addition to its stain-resistant properties, MACt Pre-Seal also provides long-lasting protection to concrete surfaces. It is quick and easy to apply, with typical application rates of 8-10 square meters per liter. However, application rates can vary depending on the porosity of the piece, so it is important to read and follow the manufacturer’s instructions. Before applying MACt Pre-Seal, it is essential to ensure that the surface is clean of all contaminants using a microfiber cloth. The sealer can then be applied evenly using a sprayer, and spread uniformly with a microfiber cloth.
In conclusion, MACt Pre-Seal is an excellent solution for protecting concrete surfaces from water and staining. Its unique silicone-based formula can increase abrasion resistance and shine on polished surfaces, and it is also UV stable and long-lasting. By changing the surface energy of the concrete, it creates a stain-repellent surface that is highly effective at preventing contaminants from adhering to it. Whether you are looking to protect a concrete basin, bath, or benchtop, MACt Pre-Seal is a reliable and effective solution that can help to keep your concrete surfaces looking great for years to come.
