Substrate Preparation

Masonry, concrete or sound existing coatings must be clean, dry, adherent, sound/solid/stable, and free from all substances, that may prevent good adhesion, e.g. formwork oil. Remove mortar burrs and all unsound, flaking/peeling off existing paints and textured renders/ plasters. Chip off all render/plaster areas showing cavities (local separation) 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-Konzentrat 111.

Consumption

Bonding of Thermal-Insulating Boards

Bead-point method: approx. 4.0 – 4.5 kg/m2
Full-surface bonding: approx. 5.0 – 7.0 kg/m2
Partial surface bonding (only with LS-Fassadendämmplatte VB 101): approx. 5.0 – 5.5 kg/m2

Reinforcing layer:
1.5 kg/m2 per mm of layer thickness
For EPS boards: approx. 4.5 kg/m2 and for mineral wool boards: approx. 5.0 kg/m2

These are indicative values. Building-dependent or processing-related deviations must be considered.

Application Conditions

Processing  temperature : +5 °C to +30 °C during application and curing for material, substrate and ambient air. Do not apply under direct sunlight or during strong wind, fog or high relative humidity.

Drying/Drying Time

The adhesive mortar Capatect Klebe- und Armierungsmasse 186M dries due to hydration and physically, i.e. by evaporation of batching water. Particularly during cooler period and at higher relative humidity the drying time is extended.

When wall anchors must be applied, they can only be fastened after a sufficiently long hardening time of the adhesive bedding, i.e. approx. 1 day. The adhesive is completely dry and ready for stress after 2 to 3 days. At 20 °C and 65% relative humidity the reinforcing layer is surface-dry after 24 hours.

Tool Cleaning

Clean tools/equipment with water, immediately after use.

Material Preparation

The Capatect Klebe- und Armierungsmasse 186M can be used with all types of flow mixers or screw pumps and suitable machine equipment for render/plaster application. If manually applied it is gradually mixed into tap (potable), cold water and agitated with a suitable low-speed electric paddle until the mixture is free of lumps. Leave to stand and swell for approx. 5 minutes and stir up again. Adjust to working consistency by adding a small amount of tap (potable) water, if necessary.

Workability/pot life depends on weather conditions: In case of manual material preparation approx. 2 to 2.5 hours; in case of mechanical conveyance max. 60 minutes. Never mix slightly hardened or stiff material with water - such material is unusable.

Example for Machine Equipment

Flow mixer Berö Calypso 15 with standard portioning or mixing spindles and feed pump Berö Speedy 15 with screw (spiral) conveyor 1/1 output.

Reinforcement Layer

(manual or machine application)

Abrade all surface irregularities of EPS butt joints, to achieve a smooth surface. Remove all adherent dust. Secure corners/edges and reveals with corner protection profiles and the edges of openings in the facade with diagonal reinforcing fabric. Apply the adhesive mortar onto the insulation boards in the width of reinforcing fabric sheet. Then press Capatect-Gewebe 650 thoroughly, sheet by sheet, into the freshly applied, still wet bonding and reinforcing layer, with an overlap of approx. 10 cm. A subsequent layer of Capatect 186 M must be applied without delay, wet-on-wet, to guarantee complete embedding of all fabric sheets and a total reinforcing layer thickness of approx. 3 – 4 mm.

Corners of the building:
If Capatect-Gewebe-Eckschutz is used, the fabric has to be applied only up to the edge.

If Capatect-Eckschutzschiene (without Reinforcing Fabric Strip) is used, the fabric should overlap the edge area for 10 cm.


Bonding of Insulation Boards

Bead-Point-Method:
Apply a bead, approx. 5 cm wide, surrounding the board edge and 3 to 6 mortar lumps (hand palm size) in the middle of the board (≥ 40% of the surface should have contact with adhesive material). Avoid mortar inside board joints!

Full surface bonding of pre-primed Capatect LS-Fasadendämmplatte VB 101:
Spray the adhesive material by machine up to approx. 10 mm thick onto the substrate. Immediately before applying insulation boards the adhesive must be treated with a square-notched trowel (length and width of notching as required for the substrate). Then the insulation boards must be pressed without delay into the freshly applied adhesive mortar bed, floated to their end position and finally pressed to ensure proper bonding. Apply adhesive material only onto the surface that can be directly covered with insulation boards, avoiding skin formation. Avoid mortar inside board joints!

Partial surface bonding of pre-primed Capatect LS-Fasadendämmplatte VB 101:
The adhesive mortar is sprayed on the substrate by suitable machine equipment as vertical beads (≥ 50% of surface must have contact with adhesive material), approx. 5 cm wide and min. 10 mm thick in their middle, with a max. centre distance of 10 cm. Then press the insulation boards without delay into the freshly applied adhesive mortar bed, float to their end position and finally press on to ensure proper bonding. Apply adhesive material only onto the surface area that can be directly covered with insulation boards, avoiding skin formation. Irregularities up to ± 1 cm can be equalised with the adhesive mortar bed. Place the insulation boards thoroughly from bottom to top, touching each other (pressing together and press on), avoiding the penetration of adhesive material into butt joints. Apply the rows of insulation boards with an offset of 50%. Follow the alignment and vertical lines for installation.

Tarpaulins should be used to protect the surface from rain during the drying phase, if necessary. Follow DIN 18 550 and DIN 18 350, VOB, part C or equivalent national regulations.
Observe the instructions given for container goods.
