Identify the surface and follow the current instructions for your exact products. Do not sand or strip uncertain old coatings. Read the safety guide before disturbing materials.
Start with the surface, not the colour
A small room with sound, previously painted walls is a much kinder first project than a damp exterior or an old staircase. Look in daylight and shine a light across each wall. Peeling, soft plaster, recurring stains and dark damp patches are information, not just things to cover.
Identify what you are painting and what is already on it. A sound modern wall, bare timber and a lime plaster wall need different decisions. If you cannot identify an old material, pause before sanding or scraping.
Give each stage its own time
Painting time is only part of the job. Washing, repairs, drying, sanding, priming and curing all need space in the plan. The tin gives minimum times under stated conditions, not a promise for a cold Fife spare room.
- Choose a manageable room and check for hazards, moisture and loose material.
- Select a compatible paint system and read its preparation, ventilation and drying instructions.
- Move belongings and protect floors before opening fillers or paint.
- Clean, repair and prepare. Inspect again before priming.
- Paint ceilings, walls and trim in a planned sequence, respecting every recoat interval.
- Keep the finished room protected while the coating cures.
Spend where it makes a difference
A decent brush, a roller suited to the paint and a reliable way to control dust are more useful than a cupboard full of gadgets. Buy a small test quantity before committing to a colour. Keep the product name, colour code and batch number for future repairs.
Common mistakes
- Trying to finish everything in one weekend regardless of drying conditions.
- Buying paint before identifying the substrate.
- Using fresh paint to hide an unresolved defect.
Get suitable professional advice for suspected lead or asbestos, persistent damp, structural movement, unsafe access or loose and unstable plaster.
