Elastomeric Additive for KRETESIL
KRETESIL FLEX is a product composed of water based synthetic elastomer to be mixed with KRETESIL. This additive provides the mix with flexibility and waterproofing characteristics. Therefore, the coating will absorb possible support deformations, minor cracks, will have higher resistance against abrasion and will strongly adhere to the surface.
KRETESIL FLEX supplied in 20 Liter plastic pails.
Consumption: 2.0 kg of KRETESIL mix per 1m² depending on the surface roughness and porosity.
Should be stored under cover away from extreme heat and direct sunlight. Shelf life is 12 months if stored in tightly sealed containers under good storage conditions

Mix one 25 kg bag of KRETESIL with 5-5.5 Liters of KRETESIL FLEX for applications with spatula and with about 6 Liters for brush applications.
Use a mechanical mixer at low number of turns. Mix till obtaining a homogeneous mixture free from lumps.
Let the mixture rest for about 5 minutes, and remix
again shortly before application.
KRETESIL mix can be applied with a brush or with spatula, for application with a brush, 2 coats are required. Before the second coat is applied make sure that the first one has hardened which generally takes place after about 5 – 6 hours according to the temperature and the porosity of the support, but do not exceed 24 hours.
Clean the tools immediately after use with clean water. During work, it is recommended to place the tools in water while not in use.
The surface of the concrete shall be sound, clean and uncontaminated.
This preparation shall be such as to leave a sound exposed concrete surface free from dust, loose particles and any deleterious matter. If the concrete surface is defective or has laitance, it must be cut back to a sound base.
Moss and lichen must be removed physically followed by treatment with fungicidal wash. After treatment, it must be washed down thoroughly with clean water.
In addition, make sure that all surfaces must be damp but not totally wet before progressing the work.
During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.
In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.
If ingested, obtain medical attention immediately. Do not induce vomiting.
