Factors To Consider When Choosing A Primer

Surface Type And Condition

Choosing the right primer is essential for achieving a durable and professional-looking paint finish. When considering the surface type and condition, it’s important to take into account whether the surface is porous or non-porous and whether it has been previously painted or if there are any signs of damage such as mold or mildew. For porous surfaces, a primer with excellent sealing properties such as Zinsser Bulls Eye 1-2-3 or Kilz Original is recommended. On the other hand, for non-porous surfaces, a bonding primer like Kilz Adhesion or Zinsser B-I-N would be more suitable.

Application Method And Coverage Needs

The method of application and coverage needs are crucial factors to consider when choosing a primer. Depending on whether the primer will be applied with a brush, roller, or sprayer, the viscosity and drying time of the primer should be taken into account. Both Zinsser and Kilz offer a variety of primers formulated for different application methods. When it comes to coverage needs, it’s important to determine the porosity and texture of the surface to calculate the amount of primer required. Kilz 2 Multi-Surface or Zinsser Cover Stain are known for their excellent coverage capabilities.
