Who Seals Concrete?

Concrete is the most popular material for construction projects, thanks to its durability and strength. However, concrete is a porous material that can quickly absorb water, oil, and other contaminants, causing it to deteriorate over time. To protect it from damage, it's vital to seal the surface. In this article, we will discuss the various types of concrete sealers and which one is right for you.

What are Concrete Sealers?

Concrete sealers are liquid coatings applied to the surface of concrete to protect it from damage caused by weather, chemicals, and other contaminants that can penetrate the surface. Concrete sealers act as a barrier between the concrete and water or other liquids, preventing the penetration of moisture and protecting the surface.

Types of Concrete Sealers

1. Acrylic Sealers

Acrylic sealers are the most common type of sealer used to protect concrete surfaces. They are available in various formulations, including water-based and solvent-based. Acrylic sealers are easy to apply, dry quickly, and provide a glossy finish to the surface. They are ideal for outdoor use as they are resistant to weather conditions and UV rays.

2. Epoxy Sealers

Epoxy sealers are more durable than acrylic sealers and provide a stronger bond to the surface. They are available in various formulations, including water-based and solvent-based. Epoxy sealers are ideal for areas with high foot traffic and heavy machinery use, such as garages and warehouses.

3. Polyurethane Sealers

Polyurethane sealers are the most durable type of sealer used for concrete surfaces. They are available in various formulations, including solvent-based and water-based. Polyurethane sealers provide a high gloss finish to the surface and are resistant to chemicals, oils, and abrasion. They are ideal for industrial and commercial use.

4. Silane/Siloxane Sealers

Silane/siloxane sealers are a penetrating type of sealer that does not change the appearance of the surface. They are ideal for outdoor use as they protect the concrete from water damage and freeze-thaw cycles. Silane/siloxane sealers are resistant to UV rays and provide excellent protection against moisture.

5. Penetrating Sealers

Penetrating sealers are a type of sealer that penetrates the surface of the concrete and chemically reacts with it to create a barrier against moisture and contaminants. They are excellent for preventing water damage and protecting the surface from freeze-thaw cycles. Penetrating sealers are available in various formulations, including silane, siloxane, and silicate.

Which Sealer is Right for You?

Choosing the right sealer for your concrete project depends on the type of surface, the level of protection required, and the conditions it will be exposed to. For outdoor use, penetrating sealers, silane/siloxane sealers, or acrylic sealers are ideal. For heavy traffic areas such as garages, warehouses, and factories, epoxy and polyurethane sealers are the best options.

In conclusion, sealing concrete is essential to protect it from damage caused by weather, moisture, chemicals, and other contaminants. Choosing the right sealer is critical to ensure that it provides the necessary protection for your specific project. Always follow the manufacturer's instructions for applying and maintaining your chosen sealer for the best results.
