Sanding is generally not required unless you're applying the primer to a glossy surface, in which case a light sanding is recommended to improve adhesion.

Generally, one coat is sufficient. However, for porous surfaces or to cover stains, a second coat may be necessary.

Clean brushes, rollers, and other equipment with soap and water immediately after use.

Yes, the primer contains a biocide that inhibits mold growth, making it suitable for use in humid environments.

Ensure the surface was properly prepared (cleaned and lightly sanded if glossy). Allow the primer to dry completely before applying the topcoat. If the issue persists, consider using a different topcoat specifically designed for the primer.

This could be due to applying too thick a coat, or applying over a surface that wasn't properly prepared. Remove the loose primer, prepare the surface again, and apply a thinner coat.

If stains are bleeding through after priming, apply a second coat of primer. For severe stains, consider using a stain-blocking primer.

Ensure proper ventilation and that the room temperature is within the recommended range. Check the expiration date of the primer. Apply a thinner coat.
