Application Procedure

Preparation of Substrate

Application substrate must be sound, mainly smooth, clean and fi ne pored. The application surface must be clear of materials which prevent bonding, such as oil, rust, paint, silicone, curing agents, detergents and paraffi n wax. Weak parts of the concrete must be repaired, plasters that are not well adhered must be removed, the surface must be fl at and sound, static cracks on the building must be repaired with a plaster containing LATEX or REPAMERK 301. Holes that have water outfl ow must be fi lled with WATERSHOCK. The surface must be saturated with water and must be kept moist during the application. On vertical and horizontal corners fi llet with min. 4 cm radius must be applied.

Application Method

Pour liquid Part B and 5-5,5 L water poured into mixing container and slowly added powder Part A. Continue mixing for at least 3-5 minutes until a homogenous and uniform mixture is obtained. Wait for 3-5 minutes and mix again for approximately 30 seconds and becomes ready to use. Prepared CHIMEX 227 mixture is applied by brush or spray machine as two or three layers. Brush application direction in each layer must be perpendicular to each other. The surface must be protected from direct sunlight and prevented from drying quickly. It is recommended to use a mesh between the layers. Using mesh increases the reinforcing properties of the product.

Consumption

1,20 - 1,3 kg/m² is applied for each layer. Recommended at least 2 coats application. If needed high protection, 3 coats application can be applied. Maximum application wet thickness is 1,3 mm for each coats.
