Product description
Weber KS122 adhesive mortar is a product delivered in the form of a dry powder mix, ready to use after mixing with water at the construction site.
Application
- Fastening foamed polystyrene and making a reinforced layer on it in the weber.therm WS insulation systems.
- Removing small unevenness in the ground.
- Fastening light architectural details, e.g. decorative profiles.
- Fastening expansion, window, under window sill profiles, etc.
Substrate preparation
Sticking insulation boards
The substrate should be stable, sound, dry, not greasy, freeze-free, free of dust, free from efflorescence in salt and loose parts. In the case of insulation of buildings with concrete sandwich panels, it is necessary to assess the condition of the textured layer. Sealing putty filling the joints between the panels must not come into contact with polystyrene. Plaster fragments with poor adhesion should be removed and supplemented with KS122 weber adhesive. Strongly absorbent and sandblasting surfaces should be thoroughly cleaned and primed with deep penetrating liquid PG229 weber. Smooth surfaces should be thoroughly cleaned and primed with a priming liquid and weber PG215 quartz sand.
Making the reinforced layer
Possible unevenness of the contact in and surfaces of previously glued thermal insulation boards should be sanded, vacuumed and leveled. Install corner strips, expansion profiles, window sill profiles and corner reinforcement mesh around openings in windows and doors, etc. Install load-bearing elements on which the roofs, handrails, blinds, etc. will be mounted. Perform additional mechanical fastening in accordance with the assumptions indicated in the technical design. The prepared surface should be collected and confirmed by an entry in the construction log.
