What is the Hydroslide Effect?

Ceresit Waterproofing slurries with Hydroslide Effect

Our range of cementitious slurries offers you the right solution, no matter from what kind of water intrusion you would like to protect your building.

The waterproofing slurries from Ceresit create an immediate water-repellent effect, which results in a stronger reduction of capillary absorption of water vs. other standard slurries.

How to test it?

1.Apply 2mm thick waterproofing slurry on a test board 50 cm x 100 cm and let it dry for one day.
2.Fill an atomizer with clear cold water, make sure that the spray creates a water mist.
3.Distance from the sample surface: 30-40 cm
4.Create a straigth angle with the vertical surface and spray the water on the sample (5 times within 10 seconds).
5.Observe the surface just after spraying.

CR 65

Hydrophobic effect:

Water is slighty soaked in the surface and drops are sliding, but they are partially absorbed on the way down. When observed against the light, the surface appears matt.

CR 90, CR 166

Strong hydrophobic effect:

Most of the water is not soaked in the surface and drops are sliding down to the bottom. When observed against the light, the surface appears glossy.

Why concrete needs best protection against water?

Concrete surfaces feature a network of micro-openings like capillaries, pores and cracks, which allows water to be absorbed: on one side, water absorbtion is necessary to hydration and hardening process; on the other, water is the major transporter of harmful chemicals into the surface, which leads to the dramatic deterioration and damage of concrete.
