How to Prepare a House Exterior Before Repainting

Repainting a home's exterior can refresh its appearance and help maintain exposed surfaces, but proper preparation should come before the first coat of paint.

The process should begin with an inspection of exterior walls, trims, doors and other painted surfaces. Peeling paint, cracks, holes, mould, stains and damaged areas should be identified and addressed before repainting begins.

Cleaning the exterior is another essential step. Dirt, dust, mould and other contaminants can affect paint adhesion, so surfaces should be cleaned appropriately and allowed to dry thoroughly.

Loose or flaking paint may need to be removed, while cracks and holes should be repaired and uneven areas smoothed. Depending on the condition and material of the surface, sanding or priming may also be required.

Homeowners should protect windows, doors, plants, pathways and outdoor fixtures before painting starts. Choosing paint and preparation products suitable for the specific exterior surface can also support a better result.

Careful preparation helps create a suitable foundation for repainting and can contribute to a cleaner, more consistent and longer-lasting exterior finish.
