Yes, many Amchem products are designed for application over existing concrete or tile surfaces, provided the substrate is sound and properly prepared as outlined above. However, the compatibility of the Amchem product with the existing surface should be carefully assessed. Consider conducting a small-scale adhesion test in an inconspicuous area prior to full-scale application to ensure satisfactory bonding and performance.

Curing times vary depending on the specific product, environmental conditions (temperature and humidity), and the applied thickness. Refer to the product data sheet for the recommended curing time. Generally, light foot traffic is permissible after a partial cure, while full cure is necessary before subjecting the treated area to heavier loads or exposure to chemicals. Premature use may compromise the integrity and durability of the coating.
