GRAE-3000-Grae Water repellent
water repellent series
3000/1000
Product Overview
– With high permeability, it has excellent durability as long as the surface of the parent body does not undergo weathering or abrasion, extending the life of the building.
– It has excellent resistance to chloride and acid rain and maintains the original appearance and color of the building.
– It prevents condensation and whitening, and prevents cracks and aging caused by freezing and thawing.
Product Features
Quick drying makes installation easy and economical. With strong waterproof and water repellent performance (solid liquid ratio of 18% or more), it is possible to construct rooftop floors.
Repainting is possible, so it can be applied before and after paint and dryvit coating.
It has good resistance to chloride and acid rain.
Even in the case of oil, it is less harmful to the human body and has a higher flash point because it does not contain thinner components (aromatic and alcohol solvents).
The large contact angle prevents water leakage even in small cracks. (up to 2mm)

Not filled in or coated on voids
Chemical bonding of Silane Group with the construction surface Reinforcement of water repellency by the Alkyl Group facing the outside
Water repellent principle of GRAE3000seriess (2)
Water repellent series treatment
Increase the surface tension of the construction surface to increase the contact angle of raindrops
Untreated
Due to the small contact angle of raindrops, the construction surfaceIt gets wet well and raindrops are absorbed into the pores of the construction surface..
Construction method
Remove dust and contaminants from the construction surface.
Work after drying the water.
Repair cracks or ditches with a quick-tee before constructing.
Work on a dry day if possible and avoid construction when precipitation is expected within 24 hours.
Apply at least 2 times with a brush, roller or spray.
