Which Exterior Wood Primer Is The Best?

The KILZ 3 Premium Primer is a top-rated exterior wood primer that is ideal for creating a stable foundation for paint. It improves adhesion, provides a uniform topcoat base, and prevents moisture buildup. The INSL-X PS800009A-01 Primer is the best exterior primer, as it sticks to surfaces like glue, making it a solid base.

Exterior primers are designed to stand up to the stresses you intend to put on your project. Alkyd-based primers are suitable for both interior and exterior bare wood substrates, as they are efficient in penetrating the wood’s porous surface and providing long-lasting adhesion. They may also be beneficial for those who have removed wallpaper as they seal the residual adhesive. Oil-based primers like Coverstain are best for raw wood on exteriors, as they block tannin bleed and can be used for the topcoat.

The Sherwin Williams® slow-dry oil-based primer is the longest-lasting exterior primer as of 2020. However, it is important not to use oil-based primers straight from the can. Mix 1 part mineral spirits with one part boiled linseed oil to create a solid waterborne stain. Benjamin Moore offers a line of exterior wood primers in latex and oil/alkyd combinations, including Fresh Start All Purpose 100 Acrylic Primer 023. Acrylic primer is water-based and is used to prime most wood siding, trim, galvanized metal, and T-111 and Hardie board siding.

For new or restored WRC, redwood, or cypress, the Benny Moore 100 or PPG 1-70 is another long-oil primer that is suitable for new or restored wood. Overall, choosing the right primer is crucial for preparing surfaces for painting and ensuring a long-lasting and durable finish.

Is kilz a good primer for outdoor wood?

KILZ ORIGINAL Interior/EXTERIOR Primer is a highly effective product for blocking graffiti, tannin, water, smoke, and other bleeding stains. It has excellent adhesion and penetration to bare wood, dries quickly, and provides a mildew-resistant coating. It is best for use on almost all exterior surfaces, including stucco, wood, masonry, and brick. It is not recommended for use on flooring. All surfaces must be clean, free of dust, chalk, oil, grease, wax, polish, mold, mildew, loose peeling paint, rust, and other foreign substances.

If washing is necessary, use a non-soapy detergent or a TSP substitute, rinse well, and allow to dry. For glossy surfaces, scuff sand thoroughly before priming. For masonry, brick, stucco, and plaster, use KILZ® PREMIUM or KILZ 2® Primers if masonry has cured less than 90 days. For fire restoration, clean damaged surfaces thoroughly before priming. Primer recommendations include water-based primers like KILZ® RESTORATION or oil-based primers like KILZ® ORIGINAL (interior use) or KILZ® ORIGINAL EXTERIOR.

When not to use oil-based primer?

Primers are essential for a paint job, as they lay the foundation for the final coat and ensure a uniform texture for paint adhesion. They can be used on wood, metal, drywall, and concrete, and help even out walls after repairs. Primers are necessary when switching paint types, changing colors drastically, or if the paint is cracking, crumbling, or causing surface damage. Oil-based primers should not be used on masonry, and it is essential to prepare the surface with primer before applying paint.

Primers can be applied to already-painted surfaces without priming, but it is generally recommended for durability and longevity. Priming is also necessary when switching paint types or changing colors drastically.

How many coats of exterior primer do I need?

Primer is a base coat that is applied before the final coats of paint, preparing the surface for better adhesion and coverage. The number of coats needed depends on factors like the color, paint type, and the condition of the walls or surface being painted. However, two coats are typically used for most projects. Understanding when and how many coats of primer are necessary before painting is crucial for a successful project.

What is the best primer for old house exterior?

Acrylic primer, also known as latex primer, is a water-based coating used to prime wood siding, trim, galvanized metal, and T-111 and Hardie board siding. Proper prep work is crucial for any project, especially exterior house painting. A good primer allows paint to adhere more strongly to the surface, smooths into cracks and pores in the substrate, and improves the paint’s ability to resist surface moisture. To find the best primer for your home, it is essential to find one that will adhere to the specific surface you’ll be painting. By following these tips, you can ensure the success of your paint job.

Do you need a special primer for exterior wood?

When choosing a primer for wood surfaces, consider the surface and whether it will be used for interior or exterior use. Exterior primers are generally better for long-lasting results and help prevent cracking and erosion. However, not every primer on the market is suitable for wood. There are specific primers designed for different types of wood. For painted wood, if the paint is chipping or cracked, apply an oil-based primer.

For new wood, with no stains and minimal grains, a latex primer may work well. If repainting good-condition wood, no primer is needed. However, if the paint is chipping or cracked, scraping off most of the old paint and applying an oil-based primer is recommended.

What is the best paint for pressure-treated wood outside?

In order to paint pressure-treated wood, it is recommended that high-quality exterior latex paint be used, with the avoidance of oil-based paints. This water-based paint is optimal for use on pressure-treated wood. Select a color that is appropriate for the project at hand, and do not be constrained by conventional notions of what is possible. Professionals are available to assist in selecting the appropriate type and color for your outdoor project. It is advisable to paint the exterior of your house at the optimal time.

What type of primer is best for exterior wood?

When choosing a primer, the primary consideration is whether to use acrylic or alkyd (oil-based) primers. Acrylic paint primers offer easier application, water clean-up, and fewer environmental considerations, and can be used for almost any surface, including wood, laminate, and metal. Alkyd (oil-based) primers offer superior stain blocking, making them suitable for both interior and exterior bare wood substrates. They are efficient in penetrating the wood’s porous surface and providing long-lasting adhesion.

Alkyd products may be preferred if wallpaper has been removed as it seals the residual adhesive. Most acrylic and oil-based primers accept both acrylic and oil-based top coats. If a project surface has an existing oil-based top coat, use another oil-based top coat or the appropriate bonding primer. Benjamin Moore’s Fresh Start ® interior and exterior primers offer superior adhesion and hold for smooth, long-lasting top coats.

Is oil or latex primer better for exterior wood?

For decades, the professional paint preparation protocol was to prime unpainted wood with oil-based primer and then topcoat it with at least two coats of latex paint. This was because oil-based primer penetrated wood fibers better than latex primer, ensuring a firmer bond and longer-lasting paint job. However, if the siding is weathered, oil-based primer is the best choice. If weathered areas can be sanded back to bright wood or if the siding isn’t weathered, latex primer is likely the better choice.

Oil-based primer hardens over time, becoming inflexible and brittle. When exposed to changing humidity, heat, or cold and dry winter air, the primer cracks under the paint, loosening its grip and causing peeling.

What kind of primer should I use on pressure treated wood?

To paint pressure-treated wood, use the correct paint and primer, such as a latex primer and water-based paint, recommended by Five Star Painting® experts. Avoid oil-based paint as it doesn’t adhere well to pressure-treated wood. Preparing the area involves cleaning with soap and water, using a commercial deck wood cleaner and pressure washer if necessary, and letting the wood dry for at least 24 hours before painting.

Do I need to prime over old exterior paint?

Primer is a crucial component in painting masonry, as it acts as a sealant to prevent moisture from seeping into cracks and causing damage. It is especially important for bare wood, as it is difficult for paint to adhere to and provides additional protection against moisture. Primer also gives wood more vibrant colors when painted over, as natural oils in wood tend to dull when painted directly on top. In addition, primer is recommended for masonry, as it is essential for preventing water damage and ensuring the longevity of the paint job. Therefore, primer is a vital component in masonry painting.
