Paint preparation for a small decorating job

Plan a small painting job around surface condition, product instructions and careful protection of nearby areas.

Identify the surface and existing finish before choosing paint. Check the paint maker's preparation guidance and make sure the product is intended for that material and location. Unknown old coatings may need assessment before sanding or stripping.

Inspect before covering

Look for loose material, dampness or an underlying defect. Paint is not a repair for a leak or unstable surface. Resolve the cause with competent help where needed, then follow the appropriate preparation process.

Protect floors and remove or mask nearby items using products suitable for the surface. Test masking tape in an inconspicuous area if removal could damage the finish. Follow ventilation and handling instructions on every product used.

Make a small sample

Try the colour and finish in the intended light and let it dry as directed. Check coverage and appearance before buying more. A screen image or a tiny colour chip may not reflect how a whole area looks.

Calculate quantity using the manufacturer's coverage and required coats, allowing for the surface and project. Include drying time between coats and before normal use.

Before opening the tin

  • Confirm surface suitability and preparation requirements.
  • Resolve dampness or damage rather than covering it.
  • Protect surrounding areas and provide required ventilation.
