Types of Concrete Sealers: Which One is Right for You?
Concrete is one of the most durable and versatile materials used in construction, but it is not immune to wear and tear. To enhance its longevity and maintain its appearance, applying a concrete sealer is essential. Concrete sealers provide a protective layer that helps prevent damage from water, chemicals, and other environmental factors. However, with various types of sealers available, choosing the right one for your specific needs can be challenging. Here’s a guide to help you understand the different types of concrete sealers and which one might be best for your project.

Silicate Sealers: Strengthen and harden concrete by reacting with calcium hydroxide to form calcium silicate hydrate.
2. Acrylic Sealers
