Covering drywall screws correctly is a crucial step in achieving a seamless and professional-looking finish on your drywall. Properly concealing these screws not only enhances the overall appearance of your wall but also ensures a smooth, flat surface that is ready for painting, texturing, or other finishes. Whether you are a DIY enthusiast or a professional, this detailed guide will walk you through the process of covering drywall screws, including the necessary tools, a step-by-step approach, and valuable tips for achieving a flawless result.
Tools and Materials Needed
Before you begin, it’s essential to gather all the necessary tools and materials to ensure a smooth and efficient process:
1. Drywall Screws
Drywall screws are specifically designed to hold drywall panels securely to the wall studs. They typically have a bugle head and are coated to prevent rust. Make sure you use the correct size and type for your drywall to ensure proper installation and avoid complications.
2. Drywall Compound (Joint Compound)
Joint compound, also known as drywall mud, comes in various formulations such as all-purpose, lightweight, and setting-type compounds. All-purpose compound is versatile and easy to work with, while lightweight compound is easier to sand. Setting-type compounds dry faster and are ideal for larger projects. Choose the one that best suits your needs based on drying time and ease of sanding.
3. Putty Knife
A putty knife is a flat, flexible tool used to apply and smooth joint compound. It comes in various widths, with a 6-inch knife being a popular choice for covering screw holes. Larger knives can be used for bigger areas or for feathering out compound for larger repairs. Ensure your knife is clean and free from any dried compound before use.
4. Sandpaper or Sanding Sponge
Fine-grit sandpaper, usually ranging from 120 to 220 grit, is ideal for smoothing out dried joint compound. Sanding sponges are flexible and can conform to the surface, making them useful for sanding compound in irregular areas. Choose the appropriate sanding tool based on the size of the repair and the level of smoothness required.
5. Primer
Primer is a preparatory coating applied before painting. It helps seal the joint compound, ensuring better adhesion of paint and providing a uniform base. Primers can be tinted to match the wall color or used as-is. Select a high-quality drywall primer or a stain-blocking primer for best results.
6. Paint
Choose a paint color that matches the existing wall color for a seamless finish. Depending on the type of paint you select (latex or oil-based), you may need different types of primer and paint applicators. Ensure the paint is suitable for the wall’s surface and finish.
7. Paintbrush or Roller
Use a paintbrush for detailed work around edges and corners, and a roller for covering larger wall areas. Select the appropriate size and type of brush or roller nap (the texture of the roller cover) based on the paint and the texture of your wall.
8. Pencil
A pencil is useful for marking the locations of screws if needed. It can help you keep track of which areas need attention, especially if you are working on a large project or multiple walls.

Step-by-Step Guide
1. Ensure Safety and Prepare the Work Area
Turn Off Power
If you’re working near electrical outlets, switches, or other electrical components, turn off the power at the circuit breaker to avoid any risk of electric shock. This is a precautionary measure to ensure your safety while working.
Clear the Area
Remove furniture and cover any remaining items with drop cloths to protect them from dust and debris. Ensuring the work area is clean and free from obstacles will make the job easier and prevent accidents.
2. Check Screw Depth
Proper Depth Check
Use a screwdriver or drill to ensure all drywall screws are recessed slightly below the surface of the drywall. The screws should be sunk just enough so that they can be covered by the joint compound without causing visible dimples or ridges. Proper screw depth is crucial for a smooth finish.
Adjust Screws
If any screws are protruding, carefully adjust them by turning them further into the drywall. Be cautious not to break the paper face of the drywall, as this can cause problems with the compound adhering properly.
3. Prepare the Surface
Clean the Surface
Before applying joint compound, clean the area around the screws to remove any dust, grease, or debris. A clean surface ensures that the joint compound adheres properly and prevents issues with paint application later.
Inspect for Damage
Examine the entire drywall surface for any other imperfections, such as dents, scratches, or cracks. Address these issues before covering the screws to ensure a consistent and smooth finish across the entire wall.
4. Apply Joint Compound
Load the Putty Knife
Scoop a small amount of joint compound onto your putty knife. Avoid overloading the knife, as this can lead to excessive buildup and make it harder to achieve a smooth finish. The goal is to use just enough compound to cover the screw holes.
Apply the Compound
Spread the joint compound over each screw hole, pressing it into the hole to fill it completely. Use the putty knife to smooth out the compound, feathering the edges to blend it with the surrounding drywall surface. Applying the compound in thin layers helps prevent cracking and ensures a smoother finish.
Smooth the Surface
Use long, smooth strokes with the putty knife to spread the compound evenly. Avoid creating ridges or lines in the compound, as these will be visible after sanding. The goal is to create a surface that blends seamlessly with the rest of the wall.
5. Allow the Compound to Dry
Drying Time
Allow the joint compound to dry thoroughly before proceeding. Drying times can vary based on factors such as the type of compound used, the thickness of the application, and environmental conditions. Typically, drying takes 1 to 2 hours, but always follow the manufacturer’s recommendations for specific drying times.
Check for Dryness
Ensure that the compound is completely dry before sanding or applying additional coats. The compound should feel solid and dry to the touch. If it’s still cool or damp, allow more time for it to dry thoroughly.

6. Sand the Area
Smooth the Surface
Once the compound is dry, use fine-grit sandpaper or a sanding sponge to smooth out the patched area. Sand in a circular motion or along the grain of the drywall to blend the compound seamlessly with the surrounding wall. Sanding helps to remove any ridges or uneven spots.
Clean Dust
After sanding, clean the surface to remove any dust created during the sanding process. Use a damp cloth or a vacuum with a brush attachment to ensure a clean surface, which is essential for proper primer and paint adhesion.
7. Apply Primer
Prime the Surface
Apply a coat of primer over the patched areas to seal the joint compound and prepare the surface for painting. Primer helps to even out the surface and improves paint adhesion. Use a brush or roller to apply the primer evenly.
Choose the Right Primer
For best results, use a high-quality drywall primer or a stain-blocking primer if there are previous stains or discolorations on the wall. Primer can be tinted to match the wall color, which helps reduce the number of paint coats needed.
Let It Dry
Allow the primer to dry completely before applying paint. Drying times for primer can vary, but typically it takes 1 to 2 hours. Follow the manufacturer’s instructions for specific drying times and application recommendations.
8. Paint the Wall
Apply Paint
Once the primer is dry, apply your chosen paint over the primed areas. Use a paintbrush for detailed work around edges and corners, and a roller for larger wall areas. Choose a paint that matches the existing wall color for a seamless finish.
Blend the Paint
Feather the paint out from the patched area to blend it with the surrounding wall. This helps to avoid noticeable lines or patches. Apply additional coats if necessary to achieve full coverage and a uniform color.
Inspect and Touch Up
After the paint has dried, inspect the wall for any imperfections. If needed, touch up the area with additional joint compound, sand it smooth, re-prime, and repaint to achieve the desired finish.
Tips for a Professional Finish
1. Use a Light Touch
When applying joint compound, use a light touch to avoid creating ridges or uneven areas. Multiple thin layers are often preferable to one thick layer, as this reduces the risk of cracks and ensures a smoother finish.
2. Work in Sections
If covering multiple screws or large areas, work in manageable sections to ensure the compound dries evenly and to reduce the risk of creating visible seams. This approach allows you to focus on smaller areas at a time, improving the overall quality of the finish.
3. Use a Taping Knife for Larger Areas
For extensive drywall work, consider using a taping knife, which is wider than a standard putty knife. This tool helps apply and smooth joint compound more efficiently over larger areas and can be particularly useful for covering large patches or seams.
4. Keep Your Tools Clean
Regularly clean your putty knife and other tools to prevent dried compound from contaminating your application and creating texture issues. Proper tool maintenance helps achieve a smoother finish and prolongs the life of your tools.
5. Monitor Environmental Conditions
Temperature and humidity can significantly affect the drying times and application of joint compound. Aim for a controlled environment with moderate temperatures and humidity levels to ensure optimal drying and application conditions.
