A Powder mixture made of natural lime, hydraulic binders, and marble fillers will enable you to achieve a concrete look effect. It is a decorative lime powder developed for interiors that can be applied with one, or two coats depending on the concrete effect you would like to create. Lime Concrete comes in a light grey base which will enable you to create a concrete imitation.
If you want to achieve a washed effect, we recommend using Calce colour wash.
Lime Concrete should be applied using a Stainless Steel Trowel.
It is made from an hydraulic base, meaning that it begins to harden after contact with water. For this reason, the best workability of the material is achieved in the first 90 minutes after the product is prepared for use. (This can vary depending on the environment, i.e temperature or humidity).
If you wish to add an extra layer of protection, you can apply our Wax d’Arte (Natural Beeswax).
How to Apply Lime Concrete
Make sure that the surface is completely smooth, and that there are no imperfections. Also make sure there are no chemicals on the surface such as oil, stains, or grease, these must be removed.
Apply Unifix Primer before Lime Concrete to ensure the correct durability and adhesion.
Lime Concrete should be applied using our Stainless-Steel Trowel. The application should be carried out with an ambient temperature between 5° to 35°C. Different decorative tools can be used depending on the desired effect. Use tools like stiff brushes, scrapers to create interest in the wet plaster. This is best done about 10 minutes after application.
Use a drill and add water slowly as you mix, then let the material rest for 10 minutes.
It can be applied on one or two coats, using a Stainless-Steel trowel.
To avoid repeated patterns, apply it using irregular movements. Once dry we suggest applying one layer of Impera wax to increase dirt resistance. Please note that although the product has a normal drying time according to its thickness, the real hardness is obtained through carbonation which occurs in contact with air. This process can last many months.

Q: Can this lime-based plaster be applied on floors?
A: Apply products especially made for that purpose only on floors, like our micro screed or micro cement.

Q: How accurate are the colours of Lime Concrete?
A: This product is coloured with industrial colouring methods, which ensures colour reliability. Still, we advise you to purchase a tester pot and/or consult with a specialist as application methods and protectors might affect the look.
Q: How resistant are the colours?
A: Lime Concrete has great colour resistance, but dark colours applied outside might lighten a bit over time due to the natural nature of the product.
Q: Can I use PVA as a primer?
A: No, you shouldn’t use PVA. For Lime Concrete always use Unifix as a base.
Q: Can I redo a wall covered with Lime Concrete?
A: Yes, you can easily redo the wall! First sand it, then cover the texture with fillers or gypsum plaster and finally prime it.
Q: Do I need a specialist to apply these finishes?
