Customer Questions & Answers

  • Question: What is the primary purpose of Zinsser 293248 Block Filler 2X High Build Primer?

    Answer: The primary purpose of Zinsser 293248 Block Filler is to prepare and prime concrete surfaces, ensuring a smooth, even finish before painting. This high build primer fills in small imperfections and provides excellent adhesion, making it ideal for both interior and exterior projects. Use it when working on garage floors, basement walls, or any concrete surface that requires a robust base. It helps enhance the overall appearance of your paint job, reduces the number of topcoats required, and extends the durability of your paint application.
  • Question: How does the 2X High Build formula differ from standard primers?

    Answer: The 2X High Build formula of Zinsser 293248 provides double the thickness compared to standard primers, allowing it to fill larger voids and imperfections in concrete surfaces more effectively. This thicker application minimizes the need for multiple coats, saving time and effort on your project. It's particularly useful on porous surfaces like cinder block, applied directly with a brush or roller. This primer not only enhances coverage but also improves durability, making your paint adhere better and last longer against environmental elements.
  • Question: Can Zinsser Block Filler be used on exterior concrete?

    Answer: Yes, Zinsser 293248 Block Filler can be used on exterior concrete. This product is designed to endure extreme weather conditions while providing a durable base for paint. It effectively seals and protects surfaces from moisture intrusion, which is particularly beneficial for outdoor concrete walls or foundations. For the best results, ensure the surface is clean, dry, and free from contaminants before application. This will maximize the longevity of both the primer and the topcoat you apply afterward.
  • Question: What is the application process for using this primer?

    Answer: To apply Zinsser 293248 Block Filler, begin by preparing the concrete surface, ensuring it is clean and dry. Stir the primer thoroughly before application. Using a brush or roller, apply a generous coat directly onto the surface, making sure to cover all areas evenly. You may choose to use a spray application for larger projects for a smoother finish. Allow the primer to dry completely before applying your topcoat. This primer can be effectively used in a variety of residential and commercial settings to enhance the surface quality of concrete.
  • Question: Is Zinsser 293248 Block Filler suitable for indoor use?

    Answer: Absolutely, Zinsser 293248 Block Filler is safe for indoor use, making it perfect for projects like basement walls, laundry rooms, or garages. The primer helps to prevent moisture problems and mold growth, ensuring a healthier environment indoors. It's advisable to ensure proper ventilation while applying the primer to minimize exposure to strong odors. Once dried, it creates a solid base for your chosen paint, enhancing the aesthetic as well as the protective qualities of your indoor surfaces.
  • Question: How much area can one 5-gallon container cover?

    Answer: A 5-gallon container of Zinsser 293248 Block Filler covers approximately 1,500 to 2,000 square feet, depending on the texture and porosity of the surface. For smooth surfaces, coverage may be at the higher end, whereas rough concrete may require more product. It’s best to measure your surface area beforehand to estimate the number of gallons needed for your project. This efficiency makes it a cost-effective option for large projects such as commercial buildings or extensive home renovations.
  • Question: Does Zinsser Block Filler require any special tools for application?

    Answer: No special tools are required for applying Zinsser 293248 Block Filler. You can use standard painting tools like brushes, rollers, or airless sprayers. For small areas or touch-ups, a brush may be beneficial, whereas a roller enhances speed and coverage for larger surfaces. Make sure to clean your tools immediately after use to prevent lingering residue. This ease of use makes it a favorite among both DIY enthusiasts and professional painters.
  • Question: Can this primer be painted over with any type of finish?

    Answer: Yes, once Zinsser 293248 Block Filler has fully dried, it can be painted over with various types of finishes, including latex and oil-based paints. This versatility allows you to achieve the desired look and durability, depending on your project's needs. For enhanced adhesion, especially with oil-based paints, it’s advisable to allow the primer to cure for a longer period. This compatibility with multiple finishes makes it an excellent choice for a range of applications.
  • Question: What makes Zinsser Block Filler ideal for cinder block walls?

    Answer: Zinsser 293248 Block Filler is specially formulated to adhere to and fill the voids in cinder block walls effectively. Its thick, high build formula ensures that all surface irregularities are smoothed over, providing a solid, paint-ready surface. This is particularly crucial for cinder block walls, which can often be uneven. Using this primer minimizes the absorption of paint into the blocks, which can distort color and finish, ensuring a more professional look.
