Capatect ZF-Spachtel 699 SPRINTER

Suitable Substrates

Substrate Preparation

Mask window sills and add-on parts. Carefully cover glass, ceramics, clinker, natural stone, painted, glazed and anodised surfaces as well as surfaces to be protected.

The substrate must be solid, dry, free of grease and dust and, in dowelled systems, have sufficient load-bearing capacity for the use of anchors. Contamination and substances with a separating effect (e.g. formwork oil) as well as protruding mortar ridges must be removed. Damaged, flaking paintwork and decorative render must be removed as far as possible. Hollow areas of rendering must be knocked off and rendered flush with the surface.
Highly absorbent, sanding or flouring surfaces must be thoroughly cleaned down to the solid substance and primed.
The compatibility of any existing coatings with the material must be expertly checked.

Preparation of Material

Ready to use.
Briefly stir the material before application. The consistency can be adjusted by adding a small amount of water.

Consumption

Bonding of insulation boards
approx. 2.8 - 6.0 kg/m²

Base coat
EPS insulation material: approx. 2.6 - 6.5 kg/m²
mineral wool insulation boards: approx. 3.9 - 6.5 kg/m²
(approx. 1.3 kg/m² per mm layer thickness)

These consumption figures are approximate values.
Deviations depending on the object or processing conditions must be taken into account.

Layer thickness of the base coat
EPS insulation material: 2 - 5 mm
mineral wool insulation material: 3 - 5 mm

Application Conditions

Application is possible in temperature ranges from ≥1 °C and up to +15 °C, ideally from +2 °C to +8 °C. The limit values must be present for at least 6 hours during the curing phase. Only after this time is the render usually skin-forming and resistant to short, light and medium rain showers and to frost down to -5 °C.
For adequate drying progress, there must be sufficient air movement and the humidity must be below 90 %. Drying is not possible at relative humidity > 95 %.
Do not apply under direct sunlight, on heated substrates or in strong air movement, as the material will form a skin too quickly and this will restrict structuring. If there is a strong air movement on the surface of the component during application and drying, there is a risk of shrinkage cracks and pores forming in the finishing render.
Do not mix factory-set Sprinter materials with ‘standard products’ or materials from the previous year.

Please refer to the leaflet "Verputzen, Wärmedämmen, Spachteln, Beschichten bei hohen und tiefen Temperaturen" (Rendering, Thermal Insulation, Filling, Coating at High and Low Temperatures) from the Bundesverband Ausbau und Fassade (Federal Association for Finishing and Façades).
In unfavourable weather conditions, take suitable measures to protect the facade surfaces being treated.

Drying/Drying Time

Bonding
Depending on weather conditions, wait approx. 2–3 days before inserting wall plugs and applying the next coat.
If wall plugs or reinforcement are required, they should only be applied once the adhesive bed has sufficiently set.

Base coat
Depending on weather conditions, decorative plaster can be applied after approx. 2–3 days at the earliest.

The necessary drying time is heavily dependent on the weather conditions and the humidity. It can be shortened under favourable drying conditions, but can also take several days under unfavourable conditions, e.g. high humidity.

Tool Cleaning

Rinse with water immediately after use in accordance with legal regulations.

Example for Machine Equipment

• Feed pump e.g. m-tec P 25 V, Inotec InoBeam F30

Delivery hoses:
Start hoses, inner Ø 35 mm; end hose, inner Ø 25 mm

Conveying distances:
Maximum delivery distance approx. 50 m; delivery head 30 m
(temperature- and device-dependent)

Sprayer:
Nozzle-Ø 8-10 mm

Pre-flush delivery hoses with lime slurry or paste before regular operation.

If work is interrupted, do not leave the delivery hose in direct sunlight, cover the material container with foil, for example, and keep the gun and nozzle under water. Stand for max. 30 min. until further processing, otherwise the material in the hose may harden.

Before a work break, the material container in the feed pump of the ‘open system’ (continuous mixer + feed pump) must be emptied as far as possible to prevent material tunnelling when restarting. If this is not observed, the material may have to be made ‘passable’ before the machine is started up (with the machine switched off). Further information on this can be found in the Caparol "Handbuch der Spritztechnologie" (Spray Technology Manual).

Follow the machine manufacturer's instructions.

Bonding of Insulation Boards

• Manual or mechanical application possible
• Lay insulation boards at least 10 cm staggered in a bond and join tightly
• Butt and bed joints must remain free of adhesive
• Never seal joints between insulation boards with adhesive
• Fill joints ≤ 5 mm with suitable flame-retardant joint foam
• Close joints and gaps > 5 mm with equivalent insulation strips
• Interlock insulation materials at the corners of the building
• Ensure that the application is flush and plumb
• Pre-fill uncoated mineral wool insulation boards in the bonding area (press-filling)
• Damaged insulation boards must not be installed

Bead-dot method
Apply a circumferential bead to the edge of the board and adhesive dots in the centre.

• Render systems - adhesive contact area ≥ 40 %

Full-surface bonding
On even substrates, the adhesive can be applied over the entire surface using a notched trowel/notched trowel. The insulation boards must be pressed, floated and pressed onto the substrate immediately, after 10 minutes at the latest, with the side to which the adhesive was applied.
Mineral wool lamella insulation boards must always be bonded over the entire surface.

Machine bonding (partial surface method)
Apply the material to the substrate by machine in the form of vertical beads. The adhesive beads must be approx. 5 cm wide and at least 10 mm thick in the centre of the bead. The centre-to-centre distance must not exceed 10 cm. The insulation boards must be pressed, floated and pressed into the fresh adhesive bed immediately. To avoid skin formation, only as much adhesive surface may be applied as can be laid directly with insulation boards.

• EPS boards - adhesive contact area ≥ 60 %
• Mineral wool insulation boards - adhesive contact area ≥ 50 %

Reinforcement Layer

To ensure a uniformly even surface and to stabilise the insulation surface of mineral wool insulation boards, we recommend levelling before applying the base coat. To do this, pre-fill a first layer with the reinforcing mortar to a thickness of approx. 2 mm and allow to dry thoroughly.

• In the corner area of building openings, embed additional Capatect Diagonalarmierung 650/00 (diagonal reinforcement strips), Capatect Sturzeckprofil (lintel corner profile) or fabric strips (approx. 25 x 25 cm) diagonally into the base coat.
• Insert plastering strips, Capatect Gewebeeckschutz 656 (mesh corner protection) and profiles into the base coat over the entire surface and align. When using Capatect Gewebeeckschutz 656 only guide the mesh strips up to the edge.
• Apply the base coat with a stainless steel trowel or by machine. Check the layer thickness with an appropriate notched trowel. The thickness of the base coat must be uniform.
• Embed the Capatect Gewebe 650 or 666 over the entire surface so that it is centred for reinforcement layer thicknesses up to 4 mm and in the upper third above 4 mm.
• Joints of the mesh must be overlapped by approx. 10 cm.
• Subsequently fill over wet-on-wet to ensure full coverage of the mesh.

Note: Do not mix SPRINTER qualities with standard products. If, for example, the Original Meldorfer^® is to be applied afterwards, Capatect ZF-Spachtel 699 SPRINTER should not be used due to the special properties of the SPRINTER setting, but the standard product.
