Positive sealing with a variety of systems

There are several positive sealing systems available in the market:
Cementitious systems (polymeric cement based), bituminous systems (by-product of crude oil refining process, or by the other name “tar”) and polyurethane systems.
Implementation processes and integration of critical impact systems on project success.
Combining concrete restoration systems together with plaster systems and decorative finishing on a variety of types requires the use of material systems that know “talk to each other”, enabling continuity between the different systems without creating failure between the layers.
Therefore, every project requires a complete and broad specification that defines the systems and their interrelationships – including curing times, types of applied color families, types of adhesives and the interval of application (window of time) between system and system.

Preparing the area before applying the sealing system is crucial to the success of their chosen sealing solution.

1. Complete or partial removal (as needed) of the previous sealing system until stable infrastructure is required if concrete restoration is required for the infrastructure.
2. In case of sealing on existing tiles, care should be taken to roughen and remove the shine of the tiles and in addition, ensure full sealing of the existing joints (fugues).
3. Complete drying of the sealing infrastructure.
4. Cleaning the infrastructure from loose particles, dust and other contaminants.
5. Application of rollers (rounded / triple casting) to horizontal (floor) to vertical (wall) fences to allow good sealing and cracking in the corners of the infrastructure.
6. Filling nozzles / holes (including segregations) / Handling cracks and stitches in existing infrastructure while creating a homogeneous, smooth, uniform texture before applying the sealing system.                                                                                                                                                                                                                                                                                                       7. Videor / gradient creation in existing infrastructure (1.5-2%) assuming that the sealing system implemented transfers the existing surface and no gradients can be repaired.
8. Treatment and preparation of drains, sleeves and other types of pipes that are expected to pass through the surface intended for sealing.

Choosing a sealing system as a suitable sealing solution over time is a direct derivative of a number of characteristics that influence the writing of the technical specifications.
