What is the difference between sealcoating and sealing?
Sealcoating refers to applying an acrylic-based protective layer to asphalt, while sealing generally means applying any protective product (acrylic, penetrating, or epoxy) to concrete surfaces like driveways and pavers.
In pressure washing work around Myrtle Beach, the terms are often used interchangeably but describe different products for different surfaces. Sealcoating specifically applies to asphalt driveways and refers to an acrylic-based topcoat that sits on the surface, protecting against UV damage and moisture. Sealing, by contrast, is the broader category for protecting concrete driveways, pavers, and other hard surfaces with various types of products.
Common concrete sealers fall into three categories. Acrylic sealers form a film on top of the concrete and provide gloss, color enhancement, and water resistance, though they require reapplication every one to three years in the coastal climate. Penetrating sealers absorb into the concrete pores, offering breathable protection against salt spray and efflorescence without changing the surface appearance, making them popular for natural-look preservation. Epoxy sealers create a hard, durable barrier ideal for driveways that see heavy use or chemical exposure, though they are more expensive and permanent than other options.
After pressure washing removes dirt, salt residue, and buildup from your concrete surfaces, a sealer locks in that clean appearance and extends the life of pavers and driveways in Myrtle Beach's salt-spray environment. Pressure washing professionals often recommend the right sealer type based on your surface condition, traffic level, and maintenance preferences.
