131 SLBefore applying the finishing coat, the base coat (reinforcement layer) must be primed with the key coat Putzgrund 610 depending on the weather, absorbency and the finishing coat used.
To protect against rain during the drying phase, hang the scaffolding with tarpaulin if necessary.
Substrate Preparation
Masonry, concrete or adherent existing coatings must be clean, dry, sound/ stable, and free from all
substances, that may prevent good adhesion, e.g. formwork oil residues.
Remove mortar burrs and unsound, flaking/ peeling existing paint and textured plaster coatings as far as possible. Cut off plaster with local separations having no sufficient adhesion to the substrate and repair to match the surrounding surface. Clean highly absorbent, sanding or chalking surfaces thoroughly up to the solid substrate level and prime with Sylitol® RapidGrund 111.
For other cases, see Technical Information "Untergründe und deren Vorbehandlung" / "Substrates and their Preparation"
Preparation of Material
Water requirement approx. 6.0 - 6.5 l per 15 kg bag.
Capatect Klebe- und Armierungsmasse 131 SL can be processed with all common flow mixers, screw conveyor pumps and plastering machines, but it can also be processed manually with a powerful, slow-running agitator with clean, cold water into a lump-free pasted mass. Let the pasted material mature for about 3 minutes and then stir again briefly. If necessary, the consistency can be readjusted with a little water after this maturing time.
Depending on the weather, the processing time for manually pasted material is approx. 2-2.5 hours, with machine delivery max. 60 minutes. Never use water to make already set material usable again.
Consumption
Adhesive: approx. 3.0 - 4.0 kg/m2Base coat: approx. 0.9 kg/m2 per mm layer thickness
These consumption figures are guide values. Building-dependent or processing-related deviations must be taken into account.
Application Conditions
During processing and in the drying phase, the ambient and substrate temperatures must not be below
+5°C or above +30°C. Do not use in direct sunlight, strong wind, fog or high humidity.
Drying/Drying Time
At 20°C and 65% relative humidity, the base coat is surface dry after 24 hours. The drying time is approx. 1 day per mm of application thickness.Capatect Klebe- und Armierungsmasse 131 SL dries through hydration and physically by evaporation of the mixing water. Delayed drying is therefore given, especially in the cool season and when the air humidity is high.
Tool Cleaning
Immediately after use with water.
Example for Machine Equipment
Capatect Klebe- und Armierungsmasse 131 SL can be processed with common plastering machines.
1) Continuous mixer Berö Calypso 15 with standard dosing or mixing shaft and delivery pump Berö Speedy 15 with screw part 1/1 power.
2) Mixing pump e.g. PUTZKNECHT S48.3 or PFT G4 (½ power)
Important information:
Please be sure to observe the guidelines of the machine manufacturer.
Electrical connection:
400 V three-phase current / 16 A each (site power distributor with FI circuit breaker)
Water connection:
Hose 3/4 with GEKA, required water pressure with the machine running at least 2.5 bar
Water flow:
Approx. 270 l / h (device type 1) Approx. 540 l / h (device type 2) The desired consistency can be set at the fine adjustment valve on the mixer tap.
Delivery hoses:
Starting hoses: inside Ø 35 mm, each 13.3 m; End hose: inside Ø 25 mm, 10.0 m
Conveying distance:
Maximum conveying distance approx. 36 m (to be optimized depending on the building and temperature)
Sprayer:
Nozzles 8 - 12 mm
Rinse the delivery hoses with lime sludge or paste before regular operation.
Do not leave the delivery hose in direct sunlight during work interruptions, e.g. cover material container with foil and keep the sprayer and nozzle under water. Waiting time max. 30 min. to continue working, otherwise the material in the hose can harden.
Before taking a break from work, the material container in the feed pump in the "open system" (continuous mixer + feed pump) must be emptied as far as possible to prevent the formation of tunnels when restarting. If this is not observed, the material must be made "passable" before starting the machine (with the machine switched off).
You can find more information on this in the brochure "Handbuch der Spritztechnologie" (Spray Technology Manual).
Reinforcement Layer
Base coat (manual or machine application):First install the edge protection to the window reveals and edges, as well as the diagonal glass fiber mesh at the corners of facade openings. Then apply the base coat in the width of the glass fiber mesh and press in the Capatect Gewebe 650/110 or alternatively the Capatect Gewebe 666/110 with at least 10 cm overlap and smooth the surface. The possible use of Capatect Gewebe 666 must be compared with the approval in advance of implementation. It is important to ensure that the glass fiber mesh is embedded "surrounded by mortar" and approximately lies in the outer third of the base coat layer. The material must be processed in an uniform layer thickness of at least 4 mm and a maximum of 10 mm.
Bonding of Insulation Boards
Bonding takes place over the entire surface or using the bead-point method. As a rule, the adhesive contact area to the substrate is > 40%. The contact area can change depending on the system used and the type of adhesive application (e.g. machine application). For this, the ETICS processing guidelines and the corresponding system approval must be observed.Special Risks (Hazard Note) / Safety Advice (Status as at Date of Publication)
The mineral powder contains portland cement and shows an alkaline reaction with water based liquids. Causes skin irritation. Causes serious eye damage. May cause respiratory irritation. Keep out of reach of children. Do not breathe dust or mist. Wear protective gloves/ protective clothing/ eye protection/ face protection. IF SWALLOWED: Rinse mouth. Do NOT induce vomiting. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Get medical advice/ attention.
Note: Only to be used by trained operatives.
