2. Key Selection Criteria of

Floor Coating / Protection

11


12/24

Only few standards are available to define

required level of protection.

EN 1504: European Standard for products

and systems for the protection and repairof concrete structures

EN 1504 includes EN 1504-2related to

Surface Protection System for Concrete

14/24

The surface protective methodscovered

by EN 1504-2 are:

hydrophobic impregnation;

impregnation;

coating...defined as treatment to

produce a continuous protective layer

on the surface of concrete ...with atypical thickness from 0.1 to 5 mm.

Importance of Details Treatment

Floor Joints, Floor to Wall

Connections, Drainage channelsmust be carefully designed and

executed using suitable materials

compatible with overall coatings /

protection system.


23/24

The nicer a new floor coating is,the longer the end user want to

keep it like this.

Proper Maintenance Program isneeded and flooring

Manufacturer can recommend

suitable cleaning regime.

Cleaning and Maintenance


24/24

A successful floor coating/protection job

requires :

- Right material selection for whichManufacturer shall be able to assist you.

- Professional application

- Proper Maintenance
