Astro Lighting Painting Guide

Astro Lighting offers a wide range of plaster and ceramic light fittings which can be painted to complement the décor or interior design of your space. Product warranty will not be impacted as a result of painting the product providing no technical parts have been tampered with.

As both plaster and ceramic are porous materials, Astro recommend the following processes to achieve a quality painted finish.

GENERAL

  • Take care when handling plaster and ceramic parts as the material is naturally brittle
  • If the material has picked up any dark marks before painting, these can be removed using either a clean white eraser, or P600 grit sandpaper for heavier marks. This will ensure they do not show through the paint.
  • Do not paint the plaster or ceramic part whilst it is fitted to the wall. This will leave unsightly cracks around the edge of the product and may result in unwanted light spill.
  • Mask off any electrical components (e.g. lampholders, LEDs).
  • Take care when removing masking to ensure edges are even and straight.

Plaster –
Best practice for a spray paint finish:

  • Use two wet coats of white high build spray primer to seal the plaster surface.
  • Apply primer to the inside of the plaster part – this will make masking easier when applying the colour paint on top.
  • Allow to dry before applying the next coat.
  • Use masking tape to mask off all internal surfaces to preserve
    original light colour, brightness and pattern.
  • Use spray colour coat on top (must be compatible with primer). Multiple coats may be required to achieve desired finish.

Best practice for an emulsion finish:

  • Use a plaster sealer primer, brushed or rolled on. One coat should be enough.
  • Allow to dry before applying top colour coat.
  • Use masking tape to mask off all internal surfaces to preserve original light colour, brightness and pattern.
  • Apply colour emulsion on top, this can be rolled or brushed on. Note, if using a brush, it may create a different texture. Multiple coats may be required to achieve desired finish.

Ceramic –
Best practice for a spray paint finish:

  • Some sanding marks in the ceramic surface may show through. Remove any deep sanding marks on the surface using P600 grit sandpaper.
  • Apply one coat of high build spray primer to seal the ceramic surface. Ceramic is slightly less porous than plaster.
  • Apply a spray colour coat on top (this must be compatible with primer). Multiple coats may be required to achieve desired finish.
