Framework Mortar

Clean, dust-free and capable of supporting a load.

Check any remaining old infilling to verify that it is structurally stable and can be sufficiently covered (at least 3 cm).

Protect the surface of the framework against dirt.

Use industry standard chamfer strips or trapezoidal strips to secure the infill.

When the framework is completely filled, attach formwork on one side.

Existing staking can be used for support.

Work wooden parts to be covered back down to the sound wood.

Replace missing wooden elements with similar ones.

Apply mortar by hand; for layer thicknesses greater than 15 mm, throw on or apply using a rendering machine.

Complete filling of framework is carried out in multiple individual layers of up to approx. 15 mm below what will later be the final surface, at a rate of max. 80 mm layer thickness/day.

Rendering of framework is carried out in multiple individual layers of up to approx. 15 mm below what will later be the final surface, at a rate of max. 30 mm layer thickness/day.

Strip and roughen the surface in preparation for applying further render layers.

Using a knife, separate individual render layers from the wood on all sides.

Waiting time before applying the finishing coat: 1 day/mm layer thickness.

Once the finishing coat has lost its gloss, carefully rub it with a soft sponge float.

Once it has hardened, mortar must not be made workable again by adding either water or more wet mortar.

Protect wet mortar surfaces against frost, rain and drying out too quickly for at least 4 days.

Hairline/shrinkage cracks are safe and are not cause for complaint as they do not impair the properties of the mortar.
