What is the purpose of a drywall primer?

To enhance texture
To seal the joint compound and provide a uniform surface for paint
To add color to the drywall
To improve adhesion of drywall panels

The correct answer is: To seal the joint compound and provide a uniform surface for paint

The purpose of a drywall primer is primarily to seal the joint compound and provide a uniform surface for paint. When joint compound is applied to drywall, it can absorb paint in uneven ways, leading to a splotchy or inconsistent finish. The primer creates a barrier that helps to prevent this issue by sealing the porous surface of the joint compound, ensuring better paint adhesion and an even color application across the surface. By using a primer specifically formulated for drywall, you can ensure that the final coat of paint goes on smoothly and adheres properly, enhancing the overall appearance of the finished wall. Additionally, it helps to highlight any imperfections that might need to be addressed before the final painting.
