How to Prep a House for Painting Interior

Giving your home a fresh coat of paint can do wonders for its overall appearance. However, before you can start painting, it is essential to properly prep your house’s interior. Prepping the walls and surfaces will ensure a smooth and long-lasting paint job. Here are some steps to help you prep your house for interior painting:

1. Clear the room: Remove all furniture, decorations, and fixtures from the room to protect them from paint splatters and to provide easy access to the walls.

2. Protect the floor: Cover the floor with drop cloths or plastic sheets to prevent paint spills and drips. Secure the protective covering with masking tape to keep it in place.

3. Clean the walls: Dust and clean the walls thoroughly using a mild detergent or sugar soap solution. This step ensures that the paint adheres properly and provides a clean canvas for the new color.

4. Repair surface imperfections: Inspect the walls for any cracks, holes, or dents. Use spackle or putty to fill in these imperfections, and sand them down once dry to create a smooth surface.

5. Patch and sand: If there are any wallpaper or textured finishes, remove them by using a scraper or sanding down the surface. Smooth out any rough spots or edges before painting.

6. Remove hardware and fixtures: Take down light fixtures, switch plates, and outlet covers. Mask off any areas that can’t be removed, such as doorknobs or window frames, with painter’s tape.

7. Mask off trim and edges: Use painter’s tape to protect baseboards, crown moldings, and window frames. Ensure that the tape is pressed firmly to prevent paint from seeping through.

8. Prime the walls: Priming the walls will create a uniform surface, cover any existing paint colors, and improve the adhesion of the new paint. Apply a coat of primer and allow it to dry completely before painting.

9. Fill gaps and caulk: Inspect the gaps between walls, ceilings, and trim. Use caulk to seal any openings, ensuring a clean and finished look.

10. Choose the right paint: Select a high-quality paint that is suitable for the room’s purpose, such as a washable paint for high-traffic areas or a moisture-resistant paint for bathrooms and kitchens.

11. Start painting: Once the prep work is complete, you can finally begin painting. Use a roller or brush, depending on the area, and apply two coats for a professional finish. Allow sufficient drying time between coats.
