What is a common type of primer used for drywall?

Acrylic latex primer is commonly used for drywall due to its excellent adhesion properties and ability to seal the porous surface of drywall effectively. This type of primer dries quickly, which is beneficial when preparing a surface for subsequent painting, and it also allows for easy cleanup with water, making it user-friendly. Additionally, acrylic latex primers are typically low in volatile organic compounds (VOCs), which contributes to a healthier indoor environment during and after application. These characteristics make acrylic latex primer the preferred choice among professionals when preparing drywall for painting, ensuring a smooth and consistent finish for the topcoat.

Other types of primers have specific uses that may not be suitable for drywall. Oil-based primers, for instance, are primarily used for sealing stains and providing a strong barrier but can be more challenging to apply and clean up. Epoxy primers are more suited for metal or surfaces that require high durability. Shellac primers are excellent for blocking stains and odors but have stronger fumes and a longer drying time, which may not be ideal for interiors. Therefore, acrylic latex primer stands out for its compatibility with drywall specifically.
