3 best concrete sealer

Concrete sealer is a protective coating applied to concrete surfaces to enhance their durability, appearance, and longevity. It is a crucial product in the realm of sealers, adhesives, hardware, and tools for home improvement. Here is some information about concrete sealers:

  1. Purpose and Benefits: Concrete sealers are used to protect concrete surfaces from various elements such as moisture, chemicals, UV rays, and general wear and tear. They help in preventing cracks, stains, and other forms of damage to the concrete, ensuring a longer lifespan for the structure. Additionally, concrete sealers can enhance the aesthetics of the surface by giving it a glossy or matte finish.

  2. Types of Concrete Sealers: There are different types of concrete sealers, including:

    • Penetrating Sealers: These sealers penetrate into the concrete pores, providing protection without altering the appearance of the surface.
    • Film-Forming Sealers: These create a protective film on the surface, providing a glossy or matte finish while offering protection against moisture and stains.
  3. Application: Concrete sealers can be applied using various methods, such as spraying, rolling, or brushing. The application method often depends on the type of sealer and the desired outcome.

  4. Surface Preparation: Before applying a concrete sealer, it's essential to prepare the surface by thoroughly cleaning and ensuring it's free of dust, dirt, and any contaminants that could interfere with proper adhesion.

  5. Common Uses: Concrete sealers are commonly used on driveways, patios, sidewalks, garage floors, basement floors, and other concrete surfaces in residential, commercial, and industrial settings.

  6. Choosing the Right Sealer: The choice of a concrete sealer depends on factors such as the type of surface, its intended use, environmental conditions, and desired finish. It's important to read the manufacturer's instructions and recommendations to select the appropriate sealer for a specific project.

  7. Longevity and Maintenance: The longevity of a concrete sealer depends on the type of sealer used, the application, and the conditions the surface is exposed to. Periodic reapplication of the sealer is necessary to maintain its effectiveness and protect the concrete over time.

In summary, concrete sealers are an essential part of home improvement and maintenance, providing protection and enhancing the appearance of concrete surfaces. It's important to select the right type of sealer for the specific application and follow proper application and maintenance procedures.

Rainguard Water Sealers Concrete Sealer

Protect, restore and extend the life of your project with Rainguard Water Sealers Concrete Sealer. Formulated to penetrate deep into the surface, Concrete Sealer is a water-based silane/siloxane water repellent. It can be used indoors or outdoors on vertical or horizontal surfaces and dries to an invisible natural finish.

Surface Preparation:

Remove dust, dirt, and debris from the surface. Gently brush out any stains with a soft bristle brush or rag using Rainguard Cleaner/Prep. Once the surface is clean, make sure to let it dry until it is “bone dry”. This will allow the sealer to absorb deep into the surface for maximum protection. Think of your surface as a sponge. A wet sponge will not be able to absorb as much as a dry sponge.

Uses & How to Apply

The Armor AR350 is a fantastic sealer for poured concrete, stamped concrete, aggregate concrete, and concrete paver surfaces. It can be applied to unsealed surfaces as well as surfaces previously sealed with a solvent based acrylic.

Coverage:

One gallon of the Armor AR350 will cover up to 175 square feet per coat. Two coats are recommended to achieve the maximum life and performance benefits. Coverage can vary depending on the porosity of substrate and the application method.

How to Apply:

  • First, make sure that the surface is clean and free of any contaminants that could prevent proper penetration or adhesion. If the surface was wet, allow at least 24 hours to dry.
  • In the early evening (5 PM or later), when the surface has had time to cool down from exposure to the sun, apply the first coat using a 3/8" nap roller or solvent-resistant HVLP sprayer. Wait 24 hours and repeat with a second coat.
  • Allow the surface 48 to dry before introducing it to water, foot, or vehicle traffic.
