What Do You Put on Drywall Before Painting: A Discussion on Pre-painting Preparation

When it comes to painting a drywall, the process of preparation is as important as the actual painting itself. Without proper preparation, the paint might not adhere well to the surface or may end up looking patchy or uneven. So, what do you put on drywall before painting? Here are the various steps and considerations for a successful pre-painting preparation.

1. Surface Cleaning: The first and foremost step is to clean the drywall surface thoroughly. Remove any dust, debris, grease, or stains using a detergent or a suitable cleaner. Ensure to follow the instructions on the cleaner and avoid using harsh chemicals that could affect the integrity of the drywall.

2. Filling Holes and Cracks: Check for any imperfections like holes, cracks, or dents in the drywall and fill them with a suitable filler. This is crucial as they can affect the smoothness of the paint job if left unfilled. Let the filler dry completely before proceeding to the next step.

3. Primer Application: Application of primer is an essential step before painting. It helps in sealing the surface, improves paint adhesion, and ensures even coverage of the paint. Depending on the type of drywall and its condition, you might need to use a specific primer designed for drywall.

4. Sanding: After applying the primer, sand the surface lightly to ensure a smooth and even finish. This helps in removing any roughness or uneven patches that might be present on the wall. Ensure to use fine-grit sandpaper and avoid over-sanding as it can damage the drywall surface.

5. Protecting Adjacent Surfaces: It’s important to protect the adjacent surfaces like floors, windows, doors, or other furniture from getting stained or painted accidentally during the painting process. Use masking tape or drop cloths to cover these areas effectively.

6. Preparing for Painting: Once all the preparations are done, you can start painting. However, before starting, ensure that all tools like brushes, rollers, and paint are ready and ensure that you have enough paint in the right color to complete the job in one go.

In addition to these steps, there are other factors to consider like weather conditions and temperature as they can affect the drying time of paint and its final appearance. It’s always advisable to follow the manufacturer’s instructions for both paint and primers for best results.

Remember, proper preparation is key to ensure a smooth and even paint job on drywall. Following these steps will help you achieve a professional-looking finish without any flaws or patches. So, before you start painting your drywall, make sure to put in enough effort in preparing it properly for a long-lasting and aesthetically pleasing outcome.
