What are cornices?
A cornice is a decorative moulding that runs where the wall meets the ceiling. In classical architecture they were ornate plaster casts; today Kenyan homes use factory-made gypsum or polyurethane profiles for faster installation and consistent detail.
Gypsum cornices
- Plain profiles — clean modern lines (GC01 series).
- Flowered designs — traditional Kenyan favourite for sitting rooms.
- Standard lengths — typically 8 ft pieces, 4 inch (100 mm) face common.
- Finish — bed with adhesive, fill joints, prime, then Crown or Duracoat topcoat.
PU (polyurethane) cornices
PU cornices are lightweight, pre-primed, and resist cracking — ideal for intricate flower patterns without the weight of cast plaster. They cut with a fine saw, glue with construction adhesive, and paint like gypsum.
Choosing cornices for your project
- Low ceilings — use smaller 4 inch profiles to avoid visual bulk.
- Designer gypsum ceilings — match cornice style to bulkhead geometry.
- Humid coastal rooms — prefer PU or MR-board ceilings before adding trim.
- Paint — use Crown vinyl matt or Duracoat emulsion for washable finishes.
Frequently asked questions
- Gypsum or PU cornice — which should I use?
- Gypsum suits traditional plastered looks; PU is lighter and faster for detailed patterns. Both paint well with Crown or Duracoat.
- How are cornices fixed?
- Adhesive bed plus small nails or screws into framing; joints filled and sanded before painting.
