Frequently Asked Questions

Q: What can we use to paint the cornices?
A: Any water based paint can be used to paint the cornices. We usually recommend an Acrylic paint. If you have a paint and you are not sure, then read its directions. If the paint directions tell you that the brush can be cleaned with water then you should be safe. Avoid solvent based paints as these will dissolve the polystyrene. Also make sure that no solvent based plaster primer is painted onto the cornice when builders are preparing newly plastered walls or ceilings.
Q: Are polystyrene cornices a fire hazard?
A: No, all polystyrene cornices and mouldings sold by Shape Smart Cornices have a flame extinguishing and retardant properties.
Q: What glue should we use?
A: We highly recommend that you use an acrylic cornice adhesive. Make sure that this is a high quality product to ensure that your cornices do not come loose in the near future. Also a high quality adhesive will not shrink and expose the joins.
Q: How much glue do we need?
A: The amount of glue required will vary depending on the size of cornice and the type and quality of wall being adhered to. A good rule of thumb is that one 310 ml cartridge of glue is sufficient for approximately 5 meters of cornice installation.
Q: Should cornices be installed before or after tiles in the bathrooms and kitchens?
A: Cornices can be installed before or after the tiles. Cornices can be glued directly onto tiles, however these need to be thoroughly clean prior to installation. Tiling up to the cornices and then glueing the cornice directly onto the wall would however be the preferred solution. Allow sufficient space for the style of cornice that you are interested in.
