Capatect MW-Dämmplatte 035 FKD 159

Substrates

Substrate Preparation

The substrate must be clean, dry and load-bearing. Impurities and separating substances (e.g. formwork oil) as well as protruding mortar burrs must be removed. Damaged, peeling paints and decorative renders 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 chalking surfaces must be thoroughly cleaned down to the solid substance and primed with Sylitol® RapidGrund 111.

The compatibility of any existing coatings with the adhesive must be checked by an expert.

Consumption

Application Conditions

During application and in the curing phase, the ambient and base coat temperatures must not be below +5 °C and above 30 °C respectively.
In this context we refer to the comment ATV DIN 18345 point 3.1.3 unsuitable climatic conditions.

Installation

Manual bonding:
Apply the adhesive belonging to the system using the bead-dot method (approx. 5 cm wide strips all around the edge, 3 - 6 palm-sized lumps in the middle of the panel) to the marked panel rear side (adhesive contact area up to 200 mm ≥ 40 %; > 200 mm ≥ 50 %). No press filling is necessary.

Machine bonding (partial surface method):
Apply the adhesive to the substrate by machine in the form of vertical beads (adhesive contact area ≥ 50 %). 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 immediately pressed into the fresh adhesive bed, floated in and pressed on. To avoid skin formation, only apply as much adhesive as can be laid immediately.

Machine bonding (full-surface):
Apply the adhesive to the substrate by machine up to a maximum thickness of 10 mm. Immediately before applying the insulation boards, comb the adhesive with a notched trowel (the width and depth of the teeth depends on the condition of the substrate). Immediately press the insulation boards into the fresh adhesive bed, float them in and press them into place. To avoid skin formation, only apply as much adhesive as can be laid immediately.

Bonding of systems with hard coverings:
Apply the adhesive belonging to the system with an adhesive contact area ≥ 60 %.

Installation:
Press the insulation boards together from the bottom to the top and press down well. Do not bring any adhesive mass into the joints of the boards. Ensure that the boards are laid flush and perpendicular. Fill any gaps ≤ 5 mm with "Capatect Füllschaum B1" or larger gaps with insulation strips. A height offset at the board joints must be avoided. In case of transition joints between different types of substrate materials or in case of weatherboard joints, the insulation boards must bridge the joint course by at least 10 cm on both sides and be supported with a secure adhesive joint.

The max. field sizes without field boundary joints for insulation thicknesses > 200 mm must be observed according to the allgemeinen bauaufsichtlichen Zulassung (general building authority approval) / Bauartgenehmigung (type approval).

Protect insulation boards bonded to the façade surface from moisture and cover with base coat for a short time.

Two-layer installation:
The boards can be laid in one layer up to 300 mm and in two layers up to 340 mm.
For two-layer installation, the boards must have an insulation thickness of at least 60 mm and a maximum of 180 mm. The second layer must be glued over the entire surface in the joint offset to the first layer. The max. field sizes of the underlying insulation approval must be observed.

Fastening:

Flush with the surface:
The insulation boards are fixed either only in the surface or in the surface and joint. The fastening can be done by the combined use of "Capatect Tellerdübeln" and the "Capatect Dübelscheibe 153" with diameter 90 mm. When fixing in the surface, distances from the anchor shaft to the insulation board edge of 15 cm and from anchors to each other of 20 cm must be observed.

Recessed:
In recessed version, the insulation boards can be fixed with the "Capatect Universaldübel 053" in combination with the "Capatect Thermozylinder 154". It is recommended to place the anchors in the recessed fixing variant only in the surface.

Countersunk:
From insulation thicknesses of 100 mm to max. 200 mm, countersunk fixing is possible with the "Capatect Universaldübel 053". For countersunk installation with a plate diameter of 60 mm, only one anchor arrangement in the surface is permissible. Distances from the anchor shaft to the insulation board edge of 15 cm and from anchors to each other of 20 cm must be observed.

Depending on the anchor variant and insulation thickness, the application limits of the application document must be observed. Observe the further information on fastening in the valid anchor tables.
