Applying Concrete Sealer and Stain Columbia MD

1. Sealer: Why use it? Concrete sealers are needed for projects that require the material to be impenetrable, or at least, less penetrable than unsealed concrete. Concrete sealers are finish coatings used to protect the concrete. Sealers act to prevent damage from traffic, water and chemical agents. Sealers reduce the porosity of concrete and prevent water and dirt from getting into the concrete.
2. Types of Sealers: Film Formers. Film formers inhibit the penetration of water and impurities by creating a barrier on the concrete's surface. Since many of these film formers create a luster or shine on the surface, they are often used to enhance exposed aggregate colored concrete.
3. Type of Sealers: Penetrates. These sealers penetrate into the concrete. They get 1 to 4 millimeters into the concrete to increase water repellency. Unlike the film formers, they do not leave a sheen or gloss.
4. Which Type of Sealer to Use? This depends on two factors: What do you want the surface to look like and what type of maintenance are you willing to do? If you want a glossy finish, go with the film formers. If you desire a matte finish, use a penetrate. If you need a slip-free surface, stay away from film formers. To keep maintenance manageable, you will need to choose the correct product. For instance, for sealing a driveway, you need a coating that repels grease and oil and prevents water penetration. To make it easier to care for an interior floor, use a coating that dustproofs the surface and resists scuffs and staining....
