This page is part of the topic 'plaster masonry'. Conventional exterior plasters to about 2 cm of thickness are almost always without problems and as supporting (co-) underground and suitable for trellis adherence. Concerns are often with thicker plaster. Even in conjunction with a reduced density and hardness of the plaster. Find out which construction of FassadenGrün are respectively applicable.
Exterior plasters may consist of one or more layers or plies, the sum of the layer thicknesses is usually 1 - 2 cm. Such plaster layers are almost always unproblematic and suitable as (co-) bearing ground for holders of a wall trellis. This also applies applied in recent times 'light' plasters, air pore lightweight plasters etc...
Either the strength of a plaster layer is already known by experience or from the construction documents, or it is determined via test drilling. For this is not only one, but at 2 - 3 places drilled to rule that a gap is there and then conclude on the extremely thick layer of plaster needed.
Not meant here are 'thick-film plasters' which are usually only 2 cm thick. Rather, it is plaster thicknesses which are significantly greater than 2 cm. Such plaster thicknesses occur on historic buildings when the plaster layer had unevenness in the masonry, recesses, and voids were compensated. In such layer thicknesses cases, FassadenGrün Trellises applications are limited. The Massive, the Easy and the average design 'Eco' kits should be avoided, since they then do not provide sufficiently low and stable anchorage in relation to the bending buckling loads. The plaster layer can then possibly not take up these bending loads and then one sees the breaking out of holders and plaster pieces.
From 3 cm plaster thickness, the lightweight design is no longer suitable, from 4 cm up the average construction 'Premium' is also no longer useable and from 5 cm thickness also eliminates 'Classic'. Please note that this is only general recommendations, depending on the local situation (degree of rope bias, type of planting, etc.).
The heavy construction is almost fully applied to on-site inspection. Likewise, the series 'Classic' is almost universally applicable if the holders are bonded in the 16 mm hole without red dowel, but with perforated sleeve SD 16085 and bonding mortar. Alternatively, the red dowels are glued and assembled there into it, then let the holder later be unscrewed. Also all the anchors for wood trellises are usually suitable, because here there doesn't arise such bending loads as with cables.
To improve the insulation of a wall, 'Heat insulation plasters' are sometimes used. They contain styrofoam beads and have a lower pressure strength than regular plaster. The above applies to them anyway. Also lugged or drawn structure plasters, ie. grade II listed buildings, have a reduced compressive strength. Here the medium is 'Classic' with glue to apply as described above.
