Repair mortars are used for the replacement of lost parts but also for the filling of
open voids and cracks in mortars, plasters and frescoes. In many cases, the use of
repair mortars is also necessary as a first step in order to stabilise historic mortars and
plasters before real conservation can start.
The use of CaLoSiL®-paste like as a binder has allowed, in combination with special
calcium carbonate fillers, the creation of a unique repair mortar fully compatible to
the most historic mortars and plaster. Thus, in combination with the calcium hydroxide
nano-sols (CaloSiL®) and the CaLoXiL®-injection grout a set of fully compatible
restoration / conservation materials is available.
Characteristic data of the repair mortar are:
Density [g/ cm3]: 1,89
Specific surface [m2/g] 2,9
Water absorption [wt.-% H20] 16
Porosity [vol.-%] 24-29
Capillary suction up to 5 cm [min.] 20
Coefficient of water absorption in kg/(m2h1/2) 4,85
Compressive strength [N/mm2] after 21 days 3
Shrinkage [%] 0,2
Hygric expansion [mm] 0,04
Freeze-thaw cyclic test, weight loss [%] after 25 cycles 20
The high capillarity and water suction capacity are typical properties. Water uptake
and release takes place rapidly and the mortars can take the role of a protection
layer. The mechanical properties of the repair mortar is sufficient to protect the historic
materials. The amount of water in the mortar is, due to the use of ethanolic suspensions
of nano-lime as binder, low and can be varied on demand.
The colour as well as the surface texture of the mortars can be adjusted by the addition
of pigments based on the demands of the object and it is possible to imitate
weathered and discoloured mortar surfaces.
CaLoXiL®-repair mortar is available in 250 mL, 500 mL, 1 Liter, 2,5 Liter and 5 Liter containers.
The repair mortar has to be stored between + 5 °C and +30 °C in a tightly closed
container. When CaLoXiL®-repair mortar remains in unopended, original containers,
storage for at least six months is possible. When necessary stir the suspension until a
homogenous mass is formed.
CaLoXiL®-repair mortar reacts strongly alkaline, Avoid spilling, skin and eye contact.
Ventilate well, avoid breathing vapours.
Wear safety glasses with side shields, or goggles, at all times while working with lime.
Wear gauntlet-type gloves.
