Does concrete sealant need to be reapplied?

Concrete sealants are liquid-based materials designed to protect concrete from surface damage and corrosion. Though chemical makeup can differ, there are two major types of concrete sealants: topical and penetrating.

Topical sealants:

• Sit on top of concrete slabs and form a layer that’s impermeable to moisture
• Protect the top, but can trap moisture that enters concrete from beneath the slab
• Best for interior application and smooth surfaces
• Often creates a slick, glossy surface
• Widely available
• Typically last 5-10 years, requires regular reapplication

Penetrating sealants:

• Penetrate the concrete, rather than sitting on top of it
• Can be used on more surface types
• Ideal for exterior applications
• Won’t become slick when wet
• Long-lasting because they don’t wear off the surface and are “breathable”"

Yes! In fact, we recommend protecting your repaired concrete with a sealant so that your repairs last. We offer three concrete sealant systems: SealantPro, DecoShield, and CSS Emulsion.

While you may find concrete sealant at big-box retailers, those solutions are temporary and will require reapplication at regular intervals (months or years depending on the product). If you're looking for a permanent solution, SealantPro is a concrete sealant that permanently bonds with the concrete surface and creates a waterproof, spill-proof barrier.

It depends on the product. SealantPro creates a permanent barrier on your concrete, whereas other solutions like DecoShield will need reapplication every 2-3 years for maximum protection and aesthetic appeal.
