what is etching on basement
Proper surface preparation is critical to the success of all SEAL-KRETE coatings. Bare Concrete: Concrete must have cured for a minimum of 30 days before application. Etch the surface with SEAL-KRETE Clean-N-Etch to allow for proper penetration and adhesion. Etching is especially important for smooth-troweled concrete surfaces (like carports, garage and basement floors) and is also recommended for rough-finished surfaces. After etching, rinse the surface thoroughly and let dry.
