Why Use a Concrete Sealer?
Concrete is an extraordinarily versatile and durable material that can last for decades. While maintenance requirements are low, concrete is not invulnerable to damage. Like wood, concrete is a porous material that breathes, ages and absorbs moisture. As with wood, concrete must be sealed to protected in order to preserve its lifespan and appearance. Fortunately, this can easily be done with a simple concrete sealer. A concrete sealer can:
- make concrete stronger
- reduce cracking and splitting
- protect against pitting, crumbling and dusting
- harden the surface, reducing abrasions
- resist moisture absorbance that will damage and weaken concrete
- stop efflorescence ("white powder") and musty odors
- protect against salts, acids and stains
- prevent molds and mildew from forming
Some concrete sealers can also inhibit or stop radon mitigation.
Not all concrete sealers do all things, so it is important to choose the concrete sealer that is right for your project...
