Acid stained concrete driveways or slabs on grade are attacked by moisture migrating from the ground, which carries dissolved salts and alkalis to the surface ("efflorescence"). This soon degrades the acid stained surfaces. Stained concrete is usually coated with a surface sealer but this aggravates the problem by trapping moisture, which activates more efflorescence inside the concrete and accelerates its deterioration.
Remove the color and surface layer by shot blasting, sand blasting, grinding, or similar.
Then, waterproof and stain the concrete in one step with LastiSeal Stain & Concrete Sealer.
Applying a clear coating or wax will protect the surface against spills and abrasion, and will add gloss to enhance the surface colors. The surface sealer will last much longer because the concrete has been deep-sealed with LastiSeal.
UV-ray and, heavy traffic, as well as efflorescence and moisture from the concrete will break down the surface sealer. It has to be re-applied every couple of years.
LastiSeal Stain & Concrete Sealer provides a better solution:
LastiSeal waterproofs the concrete against water from above or below and reduces the infiltration of water vapor. This also prevents the accumulation of water underneath the surface sealer and eliminates or reduces efflorescence.
The attractive color of the concrete stained with LastiSeal and the surface sealer will last much longer.
By stopping water migration, LastiSeal preserves and protects the concrete against deterioration.
