EST-26 Multilite Transparent

Applications

•  Additive for ESTonetex Restaura and ESTonetex Extreme mortars: provides plasticity, workability, hardness, setting control and greater thixotropy in theming, restoration, facade rehabilitation and historic heritage

•  Colourless base for coloured mineral glazes with EST-Mixol tints, to add realism to ESTonetex mortars and mineral substrates in general

•  Colourless consolidant for mineral substrates in construction, restoration, heritage, concrete and almost any mineral base that needs durable, breathable consolidation

•  Colourless mineral primer, also as a primer for silicate paints

Technical specifications

EST-26 Multilite is a water-based (low VOC), biodegradable multifunction concentrate that reacts with the mineral substrate and becomes a single crystalline body with it, insoluble in water and highly breathable. Data verified in the official technical data sheet. Full technical documentation is available on request through the contact form.

Substrates

For exclusive use on mineral substrates: ESTonetex mortars, concrete and exposed (caravista) surfaces, natural and artificial stone, lime-based substrates and restoration and heritage substrates. The substrate must be clean and dry. The degree of dilution and the number of coats depend on the porosity, absorption and degree of deterioration of the substrate.

How is EST-26 Multilite mixed?

As a mortar additive, a solution with water is prepared first: for ESTonetex Restaura, 1 part EST-26 Multilite to 6 parts water (5.6 to 5.8 L of solution per 25 kg bag); for ESTonetex Extreme, 1 part to 5 parts water (4.2 to 4.5 L per 25 kg bag). In summer, increase the solution by approx. 100-200 ml. The exact amount depending on the method (by hand or sprayed) is given in the technical data sheet of each mortar. To pigment it, add EST-Mixol tints up to a maximum of 4 %.

How is it applied?

As a colourless consolidant-primer: apply neat with a brush, roller or sprayer. As a primer for silicate paints, one generous coat undiluted; on lime-based substrates, undiluted. In other cases, the degree of dilution in water and the number of coats are decided according to the porosity, absorption and condition of the substrate. If in doubt, make a preliminary sample: if a shiny, crystalline-whitish surface remains after drying, apply it pigmented with EST-Mixol oxides matching the colour of the substrate. As a coloured glaze, mix with EST-Mixol and apply with Pulverizador-EST or a brush; on Restaura and Extreme mortars, their data sheets call for a minimum of 2-3 coats of non-covering silicate glaze. You can watch the application video.

Compatibility

Do not mix with other products: only with water (for mixing the mortar or for applying it more diluted when the substrate requires it) and, to pigment it, with EST-Mixol tints up to 4 %. It is the additive for ESTonetex Restaura and ESTonetex Extreme, and a valid primer for silicate paints and lime-based substrates. Its factory-tinted version is EST-26 Multilite Color; both versions can be combined to adjust the colour intensity.

Observations and precautions

Apply from 5 °C, both on the surface and in the ambient air; do not apply on frozen surfaces, with a risk of snow in the following 24 hours or in areas with strong sun exposure. Before applying, cover metal, glass, lacquered surfaces, wood and any mineral surfaces that should not be treated. Wear gloves, goggles and a mask, and skin protection, especially above head height; do not ingest or inhale. Professional product: always consult the safety data sheet.

Storage

Store for 24 months in its closed container, in a cool place at a temperature of no less than 5 °C. Expired product must be disposed of in accordance with current legislation.

Frequently asked questions

What is EST-26 Multilite Transparent used for?
For three uses: as an additive for ESTonetex Restaura and ESTonetex Extreme mortars, as a colourless base for coloured mineral glazes with EST-Mixol tints and as a colourless consolidant-primer for mineral substrates. It is also used to dilute EST-Monocrom.

In what proportion is it used in Restaura and Extreme mortars?
In Restaura, 1 part EST-26 Multilite to 6 parts water (5.6 to 5.8 L of solution per 25 kg bag). In Extreme, 1 part to 5 parts water (4.2 to 4.5 L per 25 kg bag). In summer, add approx. 100-200 ml of solution. It must not be mixed with other products.

How much EST-Mixol tint can be added?
Up to a maximum of 4 %, and only with EST-Mixol oxides. This gives translucent glazes with a natural effect that also consolidate the substrate. If you prefer not to mix, there is the factory-tinted version, EST-26 Multilite Color.

What is the difference between EST-26 Multilite Transparent and Color?
Transparent is the colourless base: it is pigmented with Mixol tints, used as a mortar additive and as a consolidant-primer. EST-26 Multilite Color comes already tinted from the factory (colour chart), ready to apply on mineral substrates; Mixol tint can be added to change its colour or the colourless base to reduce its intensity.

How does it differ from EST-Monocrom or EST-Multipol?
EST-26 Multilite is a mineral potassium silicate on a colourless base. EST-Monocrom is a silicate glaze in gel format with high hiding power, designed for monochrome pigmentation or intense or dark colours; it starts from EST-26 Multilite as its parent product and blends the pigments into a single colour, with a more uniform tone. EST-Multipol is a hybrid glaze of nano-acrylates and polyurethane, not a mineral silicate. If in doubt, consult our technical advice team.

Is it the same as EST-Multilitio?
No. EST-26 Multilite is a mineral potassium silicate. EST-Multilitio is another mineral consolidant in our range, based on lithium silicate, with its own data sheet and its own dilution ratios.

What is the yield and can it be diluted?
The approximate yield as a consolidant-primer is 3 to 6 m² per litre. It is applied neat or diluted in water depending on the substrate: as a primer for silicate paints or on lime-based substrates, undiluted; in other cases, according to porosity, absorption and condition of the substrate. If in doubt, make a preliminary sample.

Can it be used indoors and outdoors?
Yes, the data sheet states it is suitable for indoor and outdoor use, always on mineral substrates and from 5 °C.

How long does it take to dry?
The EST-26 Multilite data sheet does not give a fixed drying time: it depends on temperature, humidity and substrate absorption. When used as a primer for Restaura and Extreme mortars, their data sheets say to let it dry for 24 hours before applying the mortar.

Does it leave the surface glossy or whitish?
The finish ranges from mineral matt to medium gloss. If the preliminary sample leaves a shiny, crystalline-whitish surface, it is recommended to apply it pigmented with EST-Mixol oxides matching the colour of the substrate.
