Scarifying

Scarifying of concrete floors

floor surfaces

Scarifying is one of the old methods earlier used to level a floor and to prepare a concrete floor for further treatment. Scarifying creates a lot of dust and is very noisy. For this reason, scarifying is not suitable when regular business has to stay open as normal. Instead it requires a large area to be sealed off.

There is a risk that grooves/lines can be seen through a newly laid covering if the floor beneath was prepared with scarifying.  Many use self-leveling compound to try and hide this or otherwise the floor can be grinded after scarifying to remove these lines. Concrete scarifiers leaves an untreated surface of 7-9 mm to the wall, a surface that then must be treated in some other way.

What is scarifying?

A concrete scarifier is equipped with a rotating, cutting tool that rotates in a very high speed and this way tears the surface apart. A concrete scarifier is very difficult to operate and generates strong vibrations.

Grinding replaces scarifying

Today, scarifying is largely replaced by grinding in many countries and within the next few years we believe that grinding will have replaced scarifying all over the world.

HTC recommend grinding instead of scarifying in all floor preparation. Read more about HTC Superprep™.
