Concrete and Stone needs to be maintained in order to preserve its life and to enhance its appearance.

No two sealers are alike and no sealer will last forever.  Its life will depend on the type of sealer used and exposure conditions.  In general, exterior concrete and stone should be sealed every one to two years in our Colorado climate while interior concrete and stone should be sealed every five to seven years.  It is important to note that lower cost sealers purchased from local hardware stores usually can’t match the quality and performance of commercial professional grade sealers.

The type of sealer selected depends on desired aesthetics and performance.

TYPE ATTRIBUTES
Acrylic Sealer Water-based or solvent-based
UV resistant and non-yellowing
Good for exterior top coat protection
 
Polyurethane Sealer Water-based or solvent-based
Twice as thick as acrylic sealer
Excellent resistance to abrasion and chemicals
Note: moisture intolerant until it cures
 
Epoxies Hard, long-wearing abrasion resistant finish
Bonds well to concrete and cement based overlays
Available in different colors
 
Penetrating Sealer Crystallizes minerals just below the surface
Strengthens the surface
Blocks surface moisture intrusion
Blocks efflorescence
Invisible flat appearance
Brings out the natural color in stone
Note: it is not uncommon to use a topical sealer after using penetrating sealers
 

Topical sealers come in many gloss levels including no-gloss, matte, satin, semi-gloss, and high-gloss.  The higher the solid content in a sealer the higher the level of gloss.  Solvent based sealers tend to darken or enhance the color of concrete more than the water based sealers.

Care should be taken when cleaning and prepping for sealer application as it is important that all surfaces are dry before applying the sealer.
