Weber.tec 827 S 2 kg - flexible, reactive epoxy resin for sealing coatings

1. Prepared e substrates:
   The substrate must be clean, load-bearing, stable and free from oil, grease, loose and non-bound particles and other contaminants that may impair adhesion. In addition, the substrate must be even, without protruding fragments and inclusions, as well as cavities, cracks, cramps, etc. Before applying the waterproofing coating, the substrate must be properly prepared. Remove (e.g. hammer off) the protruding remnants of the mortar, cement laitance, dirt, etc. remove by e.g. hammering, grinding, washing with water under pressure, etc. Any defects should be filled with e.g. repair mortars, adequately to the type and place of damage to the substrate. Weber.sys 992 must be used to remove all grease and wax residues from glazed and metal surfaces. Ceramic linings in areas permanently under water must be mechanically roughened prior to the application of weber.tec 827 S. The product should not be used on glass mosaic and glass. Depending on the substrate, the primers listed in the table are required. Subsequent coats of weber.tec 827 S should be applied to the still sticky or hardened primer, sprinkled fresh with quartz sand for resins (particle size 0.1 to 0.5 mm). The peel strength of the surface on mineral substrates should be at least 1 N / mm?. Moisture content must be below 4% by weight. When weber.tec 827 S is used in areas that are permanently under water, the seal must form a closed bathtub. Avoid moisture ingress into the seal.
2. Product preparation:
   Components A (resin) and B (hardener) are delivered in the correct proportions ready for use. It is forbidden to change these proportions. In the case of a "combi" container, the bottom of the upper conical container with hardener, without removing it from the lower container, should be repeatedly pierced with a steel punch and allow the hardener to completely flow into the lower container and immediately start mixing with a mixer in a slow-running drill (mix in component A container). Pay attention to the thorough mixing of ingredients at the sides and bottom of the container. The mixing time should not be less than 3 minutes and should result in a homogeneous, homogeneous mixture without visible streaks. If the product is supplied in separate containers, pour component B into component A. To remove the remains of adhering component B in the emptied container, pour the slightly mixed material and thus moisten the walls of component B.
3. Instructions for use:
   The weber.tec 827 S application is applied with a triangular-toothed trowel (trowel with a toothed rack No. 1) and immediately afterwards evenly spread with a smooth trowel. The layer thickness applied in the first pass is approx. 1 - 1.5 mm (depending on the area of application), which corresponds to a consumption of 1.3 - 2.0 kg / m?. The second layer should be done at the earliest 24 hours after the first and no later than after 3 days. To obtain a tight coating 1.3 - 2 mm thick, the material must be applied in 2 passes. If the ceramic cladding is laid over cement glue, the fresh layer of weber.tec 827 S applied in the second pass should be sprinkled with 0.7 - 1.2 mm quartz sand for resins. The thickness of the quartz sand topping must not exceed 0.5 mm. After the resin has hardened, remove the excess sand and lay the tiles. The application temperature (air and substrate) must be between + 10 ° C and + 30 ° C. At the same time, the temperature of the substrate must be at least 3 ° C above the dew point. Cleaning of tools Fresh with weber.sys 992, after mechanical hardening.
4. Consumption:
   weber.tec 827 S: approx. 1.5 to 2.5 kg / m? (depending on the application) - layer thickness from 1.2 to 2 mm
