binders and fixers

Binders and fixers are natural glues or synthetic resins whose function is to bind together fillers or aggregates and to stick them together on different substrates according to their compatibility. There are different types of binders and fixers. Natural binders and fixers such as casein and synthetic binders and fixers such as acrylic or vinyl binders. Natural limes are part of natural binders such as air lime paste or powder and natural hydraulic lime (nhl3.5) or Roman hydraulic lime. They are not fixers because they do not add to mixtures. they are necessarily the main binder of the mixtures.

powdered casein
powdered casein
in stock


powdered casein is a 90 mesh (very fine, good quality) food-grade acidic casein obtained from milk. It is a natural binder for making paints and plasters and an excellent fixer for lime. It is only applicable on solid and rigid supports but not on canvas or paper because it forms a hard and very solid film. Casein is very popular in decoration because it gives a very beautiful velvety mat, so it goes perfectly with lime. To use it it will be necessary to transform it into glue, for that we must make it react with an alkaline, such as lime (old and best method), ammonium carbonate or borax.

lime paste
lime paste
in stock



the lime paste calci lime is manufactured in ebreuil in the alloy. This pure and 100% natural lime paste is handcrafted, unlike powdered industrial lime, which gives it remarkable aesthetic and ecological qualities as well as a remarkable carbonation (becomes after drying as solid as the original stone which has been fired). It is, once dry, a very pure white (grayish when wet), very smooth and grain-free and does not flour. It is very suitable for the realization of frescoes, limewash, fine plasters and stuccos and tadelakt. This lime has aged 12 months and can be stored indefinitely as long as it remains in its lime water, it will only be better.

alum salt powder
alum salt
in stock
alum salt or potassium alum (coarse salt) is a natural fixative for lime. its role is to help fix the pigments in lime.It is mainly used in whitewashes and tends to make them more solid. it is not used to help fix lime on a support, in this case its effectiveness is less, therefore prefer another fixer with which you can associate it. Its dosage is 10% relative to the weight of the lime.

air lime powder cl90
air lime powder cl90
in stock


slaked aerial lime cl90 in white powder for traditional plasters and decorative paints and plasters. This air lime slaked in white powder is used to produce lime paints (or whitewashes) as well as interior or exterior plasters with sands or marble powders and pigments. The flexibility and breathability as well as its unmatched sanitizing properties make lime a binder perfectly suited to old substrates. As this lime sets in contact with air, it is however not possible to make thick mortars (max 1.5cm).

rabbit skin glue
rabbit skin glue

rabbit skin glue is a binder for paints (tempera) and coatings (gesso). Rabbit skin glue has a very powerful tack and due to its flexibility, it is used to glue all flexible media such as paper, canvas or wood which are its favorite media. It is also for this reason that 'it is the ideal lime fixer on wooden substrates, especially since it has a matt and velvety appearance like lime

lime water, natural recalcifying varnish
lime water
in stock

lime water is a 100% natural varnish resulting from lime quenching which is used to create patinas, consolidate whitewashes, stones, frescoes. The water is used to extinguish quicklime and it is during this extinction, when a strong heat is released, that this water becomes charged with calcium hydroxide to form lime water. Then when it is used, lime water reacts with carbon dioxide in the air to form calcium carbonate (caco3, calcite found at the end of stalactites in caves) which is then freezes on the surface to form a transparent limestone.

saponified wax
saponified wax
in stock

white saponified wax is the most used beeswax in decoration because it can be diluted with water. Once it becomes transparent while leaving a satin to shiny appearance depending on its polishing. This wax is made in our workshop in an artisanal way by emulsion with ammonium carbonate from 100% pure and natural white beeswax. It can be applied on any solid to slightly flexible support, such as walls and ceilings, lime or plaster coatings, wood etc ... it is possible to tint it to paint (as in antiquity), or to create patinas on plaster.

potassium silicate
potassium silicate
in stock
potassium silicate is a binder, consolidator and pore filler for porous mineral materials. it can be added with pigments for the manufacture of paints. potassium silicate is a low-viscosity, transparent and odourless aqueous solution, suitable for mineral substrates that need to breathe, such as in ecological housing, old buildings and historical monuments. Our silicate does not contain any resin unlike 28° 30°, it will be more efficient and solid.
