Types of Concrete Sealers
Film-Forming Sealers
Film-forming sealers create a protective layer on the surface of concrete. This layer acts as a barrier against UV rays, moisture, and other environmental factors. These sealers are particularly effective in enhancing the color and appearance of concrete surfaces. However, they may wear off over time, especially in high-traffic areas.
For outdoor applications in regions with intense sunlight, consider using tinted film-forming sealers. Tinted options like Woodoc 35 and Woodoc 55 are highly recommended. These products provide superior UV protection compared to clear sealers such as Woodoc 30 and Woodoc 50. The transparent iron-oxides in tinted sealers enhance their durability against sun exposure, making them an excellent choice for maintaining the aesthetic appeal of your concrete surfaces.
Penetrating Sealers
Penetrating sealers, on the other hand, work by infiltrating the concrete surface. They bond with the concrete at a molecular level, providing long-lasting protection without altering the surface appearance. Unlike film-forming sealers, penetrating concrete sealers do not wear off easily. They resist yellowing, a common issue with sealers that create a membrane. This makes them ideal for maintaining the natural look of your concrete.
When selecting penetrating sealers for outdoor use, consider the following top-rated options:
Multipurpose Solvent-Based Sealer: This clear thermoplastic sealer is UV resistant and provides a durable, flexible coating on concrete surfaces.
Multipurpose Water-Based Sealer: A non-yellowing polymer sealer that is UV resistant and alkali resistant, suitable for vertical surfaces.
Siliconseal Solvent-Based Sealer: This penetrating liquid reduces water absorption and is effective for hydrophobic infusing, suitable for various mineral surfaces.
Siliconseal Water-Based Sealer: A penetrating waterproofing system that reduces water absorption and is low in VOC, making it suitable for various applications.
By understanding the differences between these types of concrete sealers, you can make informed decisions that best suit your outdoor concrete needs.
Benefits of UV-Resistant Sealers
Enhanced Durability
UV-resistant sealers significantly enhance the durability of your outdoor concrete surfaces. These sealers create a robust barrier that protects against the damaging effects of sunlight.
