Telling Unilit B-Fluid X-B - A extremely fine natural hydraulic lime grout for bonding delaminated plasters and renders by injection between detached mortar or plaster and their substrate.
Unilit B-Fluid - A range of natural hydraulic lime grouts for injection, static reinforcement, stabilisation and filling of voids within wall structures.
Telling Unilit B-Fluid X-B Natural Hydraulic Lime Binder
An extremely fine, ready mixed mortar based on an inorganic, natural hydraulic lime binder, and a very fine filler. The mortar is characterised by a low content of soluble salts, a low modulus of elasticity and high vapour permeability. It is perfectly stable and carefully prepared to limit problems of microfissures and to prevent premature drying out. The binder will store a large quantity of salts, which may come from the substrate and migrate because of humidity, which guarantees the performance and extended life of the mortar.
The mortar is designed for injection between a detached mortar or fresco and the substrate and is injected in holes drilled in the loose render.
Packaging: 25 kg bags, in powder form.
Density: 1000 kg/m3.
pH: > 10.5.
Fire classification: Non-flammable (M.O.)
Granular size: = 0.01 mm.
The injection holes and cracks should be pointed with a suitable Unilit mortar as clause 610, 520 or 530.
Consult Telling technical service department for advice on the suitability of the substrate.
Consult with Unilit technical literature for details. Hydraulic lime mortars are specialist products and it is recommended that Telling Lime Products are consulted early in the design process.
Grout Mix: Unilit B Fluid X B premixed natural hydraulic lime grout.
Mix proportions: Premixed - Seek advice from Telling.

Product reference: Unilit B-Fluid X-B Natural Hydraulic Lime Grouting Mortar.
Application: Mix Unilit B-Fluid X-B with 15-32% of clean water. Mix manually or mechanically for 5 to 8 minutes.
Insert mortar using a syringe with a maximum pressure of 1-2 bar, commencing from the lowest point of the detached mortar and working upwards in bands of about 100 mm in height, to avoid an overpressure and a complete detachment of the loose mortar. The mortar remains workable for 2 hours and dries in 24-48 hours. Protect from frost for 48 to 72 hours.
Unilit B-Fluid Natural Hydraulic Lime Grouts.
A range of 5, ready mixed mortars designed for injection, static reinforcement or stabilisation, based on an inorganic binder of natural hydraulic lime and a filler. The mortars are perfectly stable and delicately prepared to limit problems of microfissures and to prevent premature drying out. They are characterised by a low content of soluble salts, a low modulus of elasticity and high vapour permeability. The mortars will store a large quantity of salts, which may come from the substrate and migrate because of humidity, which guarantees the performance and extended life of the mortar.
The mortars are designed for application by injection or pouring on walls, consisting of different components.
Unilit B Fluid 2, 3 & 4 grouts are formulated for injection, static reinforcement or stabilisation. These preblended mortars, with different granular sizes, allow application to fill voids within walls and masonry structures by injection or pouring. For example, the core of a wall consisting primarily of earth clay and stone will after severe water degradation be washed out to the degree where only the outer walls remain as masonry. The injection of Unilit B Fluid 4 provides linkage between the two façades to re-stabilise the structure. Unilit B Fluid 2 is a finer stabilising material used where cracking is evident due to movement or shear. The location and size of voids should be determined, and holes drilled in the masonry at intervals to ensure the flow of grout under gravity to fill the voids. Alternatively, where it is possible to access to the core by removal of masonry units the grout can be poured into the void, and mortar used to fill the accessible void as below.
