Lixol is presenting three lime-based binder solutions.

  • Two solvent-based lime-based binders: LIXOMAT IL and LIXOMAT D60 (also available in LIXOMAT 35 D60 and LIXOMAT 35 IL versions)
  • One water-based lime-based binder: LIXOMAT HYDRO

Properties of paints containing lime-based binders

This test consists in tracing three lines (pencil, red marker, black marker) on a painted substrate and then successively applying 120 μm paint’s layers until the lines are totally covered.
This test has been used to compare classic acrylic paint with matt lime-based paint containing LIXOMAT 35 D60. The covering of the pencil lines (on the 3rd layer, 360 μm) and the black marker (on the 4th layer, 480 μm) is comparable for both paints. The red marker line is covered on the fourth layer with the matt lime-based paint containing LIXOMAT 35 D60 whereas with the classic acrylic paint, the red line is not covered due to the water-solubility of the red pigment.

This test has been carried out to assess the ease of application and the open drying time of the paint before keeping marks due to the drying. Classic acrylic paint is compared to the acrylic/LIXOMAT HYDRO mix paint as well as to the matt lime-based paint containing LIXOMAT 35 D60. These overlapping marks tests consist in applying a first coat of paint in the centre of a plasterboard substrate, then applying a second coat that partially covers the initial one (on the left) 2 minutes after and then a third one that partially covers the initial one (on the right) 4 minutes after the first application. The test carried out using classic acrylic paint shows significant overlapping marks at 2 and 4 minutes. The blending of this acrylic paint with LIXOMAT HYDRO reduces these resumption marks.

Finally, the use of the matt lime-based paint containing LIXOMAT 35 D60 eliminates theses overlapping marks due to the paint’s longer open time provided by LIXOMAT 35 D60.

No overlapping marks can be seen.

The purpose of this simple test is to highlight the good stain-blocking property of lime-based binders. This test consists in creating three series of stains on a plasterboard plate using the following products: oil, coffee, tobacco, wine, wood tannin and wall washing product. These spots are left for one hour in order to mark the substrate, and are then wiped and dried. Paint is then applied on these stains in order to evaluate the capacity of the paint to block the migration of theses stains to its surface. A layer of paint is applied on the centre serie and two on the right serie. Classic acrylic paint has difficulties to block the migration of most stains through the layer. Indeed, the stains are still visible after two layers of paint.

Blend the LIXOMAT HYDRO with the acrylic paint improves the capacity of the paint to block the stains. Water-based limed matt paint containing 100% LIXOMAT HYDRO improves the stain-blocking property even more. Only the tobacco and coffee stains remain partially visible. The use of the solvent-base LIXOMAT (D60, IL and 35 D60) in paint provides an excellent stain-blocking property to the paint. Indeed, the stains are blocked as soon as the first layer is applied as shown in the figure.
