Floor Acid Etching is achieved by adding a solution of HydroFluoric Acid (HF), which will will eat into a floor surface and ‘etch’ it and provide a level of slip resistance afterwards.

The information at the following HSE websites describes the positives and the negatives on the topic of Acid Etching: -
Case Study: Poor floor choice threatened opening of building
When a floor is etched it will roughen the surface up by a small amount by creating small pinholes and making the surface look like an Alpine Mountain Pass but in miniature. But in reality the valleys are so small that they will soon fill in with dirt, floor waxes etc. and as a result the PTV (Floor Pendulum Test Value) will again be too low to be safe. The other problem is the acid damages the floor significantly; any floor with a pleasing shiny surface will look rather dull, which is great to pass a Floor Pendulum Test but brings its own problems with it
Subsequently, suppliers of acid etch floor coatings then recommend adding a dash of hydrofluoric acid to the cleaning water to maintain the micro porous finish; the result is a safe floor but with
