Our cornice products are manufactured from XPS, a high-density foam which is used primarily as insulation material in Australian construction, due to it's superior thermal properties.
The compostition and light weight of the material means that it is not installed with the same products as standard plaster cornice, and also has specific requirements in terms of the paints and adhesives that can be used.
Below are compatibility tables which clearly indicate which products can and can't be used with our cornice.

Compatibility – XPS Cornice |
||
|
Adhesive |
Water-based, solvent-free; specifically formulated for lightweight cornice/XPS |
Soudal Strong As Nails Super Grab (Water Based); Selleys Liquid Nails Fast Grab (Water Based); Parfix No More Nails (Water Based) |

Not Recommended – XPS Cornice |
||
|
Adhesive |
Solvent-based construction adhesives or contact cements; expanding foams |
Solvents can attack/melt XPS; foams expand and can distort the cornice profile |
|
Filler |
Hard-setting plaster fillers or cement-based compounds, Silicone |
Too rigid; prone to cracking at joins and may not bond well to XPS, Silicone is not paintable |
|
Paint |
Oil-based enamels; solvent-borne primers/sealers |
Solvent content can degrade the XPS surface, causing bubbling or melting |
