Good paint preparation begins with deciding whether the wall is suitable for a simple cosmetic project. This example covers a small, sound interior surface with a known nonhazardous coating and minor imperfections. It is not a tested paint-system recipe.
Do not disturb unknown old paint, suspected asbestos-containing material, recurring cracks, damp areas, or mold. Resolve the cause with appropriate professional help first. EPA recommends lead-safe certified contractors for renovation of pre-1978 homes.
Plan the project
Beginner · An afternoon of active work, plus product drying time
Tools and materials
Required tools
- Work light
- Putty knife for a compatible filler
- Cleaning cloths
- Suitable work-area protection
Materials
- Drop cloths
- Manufacturer-approved cleaner
- Compatible patching compound for minor defects
- Primer if required by the coating system
What a successful preparation check looks like
The surface should be appropriate for the chosen coating system, clean, sound, and dry according to product directions. If a defect keeps reappearing, more filler or primer is not a diagnosis. Resolve the underlying issue before continuing.
Project steps
Inspect and define the boundary
Look closely at the coating and the condition of the wall. Establish that the materials are suitable for this simple project. If you cannot identify the coating or there is damage suggesting a larger problem, stop before scraping or sanding.
Prepare the room
Move small furnishings away and protect remaining surfaces. Arrange good lighting and ventilation consistent with the product instructions. Keep access routes clear. Leave electrical devices alone; this example does not include removing outlets or working on wiring.
Clean the known-safe surface
Use a method compatible with the wall and coating. Test in an inconspicuous area first, avoid saturation, and let the surface dry as required. Paint applied over grease or dust may not adhere as intended.
Address minor cosmetic defects
Use a compatible patching product only within its specified depth and application limits. Follow its drying and finishing directions. Avoid expanding the project into large cracks, damaged substrates, or unexplained soft areas.
Check before opening the paint
Inspect under side lighting, remove remaining debris appropriately, and confirm whether spot priming or full priming is required by the paint system. Allow the stated drying time rather than guessing from the surface appearance.
Safety & limits
- This sequence excludes hazardous coating removal and electrical work.
- Product ventilation and protection instructions still apply, even to a small room.
