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.

Paint roller
Choose a sleeve intended for the surface texture and coating. A suitable small roller can be better than a broad one in a tight space, particularly around edges and fittings.
Masking tape
Match tape to the surface and removal timing. Test first where damage would matter, and do not assume every tape advertised for decorating is safe on delicate finishes.
