TAKING CARE OF YOUR SCULPTURE

It is worthwhile spending a little time each year to keep your sculpture looking its best.

Oamaru stone is very porous, so water soaks in easily. As moisture sits on the stone mould can develop, or in freezing conditions the moisture expanding within the stone can lead to gradual deterioration over time.

Sealing the sculpture with a silicon or water based stone sealant will prevent moisture entering the stone, moisture will 'bead' off and the sealant still allows the stone to “breathe”.

1. Rinse:
   First, remove any mould be rinsing the sculpture in 30 seconds diluted bleach — or a similar product.
    

2. Sand:
   Some mould may be stubborn and require a light sand to remove — we recommend a 120 grit sandpaper.
    

3. Dry:
   Leave to completely dry.
    

4. Seal:
   Once dry, brush or spray on a sealant (the brush is better) — be generous, the sealant will soak into the stone for a short time before it starts to repel itself. If you use a silicon based sealant, the stone may end up a creamy colour. If you wish to return to its white lustre — simply sand it lightly again once dry — the sealant will still work as it soaks deep into the stone.
