Sikagard®-700 S is a one part water repellent impregnation for absorbent cementitious substrates. It penetrates well into the open pores of the substrate, providing durable water repellency, while still allowing water vapour diffusion in both directions.
Sikagard®-700 S complies with the requirements of EN
1504-2 for hydrophobic Impregnation (penetration
depth class I).
Suitable for use in hot and tropical climatic conditions.
Sikagard®-700 S is used as water repellent and colourless protective surface treatment on absorbent exposed materials such as concrete, cementitious rendering, concrete tiles, fibre cement, brickwork (clay
and lime sand, non-vitrified), natural stone.
Sikagard®-700 S can also be used as hydrophobic
primer under solvent based or emulsion protective
coating. Sikagard®-700 S is used as water-repellent impregnation (hydrophobic treatment) for absorbent
substrates such as concrete in civil engineering or
building concrete structures.
Suitable for protection against ingress (Principle 1,
method 1.1 of EN 1504-9)
Suitable for moisture control (Principle 2, method 2.1
of EN 1504-9)
Suitable for increasing the resistivity (Principle 8,
method 8.1 of EN 1504-9)
CHARACTERISTICS / ADVANTAGES
▪ Reduction of capillary water absorption
▪ Reduces efflorescence

▪ Improves thermal insulation
Can be overcoated with solvent based and dispersion coatings
Higher durability and resistance than conventional
silicone based treatments
Does usually not change the appearance of the substrate
▪ Does not act as a vapour barrier
▪ APPROVALS / CERTIFICATES
