Acid-based formulation designed to treat polished or lapped tile surfaces, preparing them for the application of Polishield products that seal surface porosity and help protect the surface from dirt and chemical attack.
Its gentle etching action removes residues from polishing and creates controlled micro-texture, essential to maximize adhesion and overall performance of the subsequent Polishield surface treatment.

The product is based on mineral acids and can be applied neat to the surface using a rotary roller. The application rate depends on the surface type and on the specific processing line setup.
