Key Features of Sherwin-Williams A-100 Exterior Latex Paint

Superior Durability

Sherwin-Williams A-100 Exterior Latex Paint is formulated to withstand extreme weather conditions, including heavy rain, strong winds, and intense sunlight. Its durable finish ensures long-lasting protection and appearance, making it a reliable choice for homeowners.

I recall a project where we painted a beachfront home that constantly faced salty air and strong winds. The homeowner was concerned about frequent repainting due to the harsh environment. We used A-100, and even after several years, the paint job remained intact and vibrant, proving its superior durability.

Excellent Adhesion

A-100’s advanced formula ensures excellent adhesion to a variety of surfaces, including wood, stucco, and masonry. This versatility makes it an ideal choice for different types of exterior projects, providing a strong bond that resists peeling and blistering.

We recently worked on an old brick building that required a fresh coat of paint. The brick surface was rough and challenging, but A-100 adhered perfectly, creating a smooth and durable finish that impressed both the client and our team.

UV and Fade Resistance

Importance of UV resistance in exterior paint: Exposure to UV rays can cause paint colors to fade over time, diminishing the aesthetic appeal of a home. A-100 is formulated with UV-resistant properties that protect against fading, ensuring that the colors remain vibrant and fresh-looking for years.

The lasting vibrancy of colors on a sun-exposed wall painted with A-100: On a project involving a south-facing wall that received intense sunlight, we used A-100 to ensure the color would last. Years later, the wall still looks as vibrant as the day it was painted, showcasing the paint’s excellent UV and fade resistance.

Mildew and Moisture Resistance

Benefits of mildew-resistant paint in humid climates: In humid climates, mildew can be a significant problem, leading to unsightly stains and potential health issues. A-100’s mildew-resistant formula helps prevent mildew growth, keeping exterior surfaces clean and healthy.

Portland’s damp climate often poses challenges for maintaining exterior paint. On a recent project, we used A-100 to paint a home surrounded by dense foliage. The paint’s mildew resistance ensured that even in the damp conditions, the surfaces remained free from mildew, maintaining the home’s pristine appearance.Sherwin-Williams A-100 Exterior Latex Paint combines durability, adhesion, UV resistance, and mildew resistance to deliver a superior exterior paint solution that withstands the test of time and weather. 

In Our Experience:

"Sherwin-Williams A-100 Exterior Latex Paint has consistently delivered outstanding results. On a project in Portland, we used A-100 on a home facing frequent rain and wind. The paint's superior adhesion and weather resistance kept the exterior looking fresh and vibrant for years. Clients appreciate the low VOC formula, which aligns with eco-friendly practices, and the long-lasting protection it provides against the elements. The positive feedback from homeowners reaffirms that A-100 is a reliable choice for any exterior painting project."

Application Tips for Sherwin-Williams A-100 Exterior Latex Paint

Surface Preparation

Importance of proper surface preparation for a flawless finish

Proper surface preparation is crucial for achieving a long-lasting and flawless paint job. It ensures that the paint adheres well and creates a smooth, even finish that enhances the durability and aesthetic appeal of the painted surface.

Steps to prepare different surfaces before painting:

  • Wood: Clean the surface to remove dirt, grease, and loose paint. Sand any rough areas and fill holes or cracks with wood filler. Apply a primer if the wood is bare or previously painted with a different type of paint.
  • Stucco: Remove loose or peeling paint and clean the surface thoroughly. Repair any cracks or damaged areas with stucco patch. Apply a primer to ensure good adhesion.
  • Masonry: Clean the surface to remove dirt, efflorescence, and loose material. Repair any cracks or holes with masonry patching compound. Use a masonry primer to enhance adhesion and provide a uniform base.

Best Practices for Painting

Techniques for applying A-100 to achieve a smooth, even coat:

  • Brushing: Use high-quality synthetic brushes designed for latex paint. Apply the paint in long, even strokes, maintaining a wet edge to avoid lap marks.
  • Rolling: Use a roller with a nap length appropriate for the surface texture. For smooth surfaces, a 3/8-inch nap roller is ideal, while rougher surfaces may require a 1/2-inch or 3/4-inch nap. Apply the paint in a W or M pattern, then back-roll to distribute the paint evenly.
  • Spraying: For large or uneven surfaces, consider using an airless sprayer. Ensure the sprayer is properly calibrated for latex paint, and apply the paint in even, overlapping passes.

Tools and equipment recommendations:

  • High-quality synthetic brushes for cutting in and detail work.
  • Rollers with appropriate nap lengths for different surface textures.
  • Airless sprayers for large or textured surfaces.
  • Painter’s tape to protect areas not being painted.
  • Drop cloths to protect the ground and surrounding areas.

Drying and Curing Times

Sherwin-Williams A-100 Exterior Latex Paint typically dries to the touch within 2-4 hours and is ready for a second coat after 4 hours under optimal conditions. Curing, where the paint reaches its maximum hardness and durability, usually takes about 30 days.

Optimal conditions for painting:

  • Temperature: Ideal painting temperatures range from 50°F to 90°F. Avoid painting in direct sunlight or during extreme temperature fluctuations.
  • Humidity: Moderate humidity levels are best. High humidity can slow the drying process, while very low humidity can cause the paint to dry too quickly, leading to application issues.

On a recent exterior project, we prepared and painted a two-story home over a weekend. On the first day, we prepped and primed the surfaces in the morning and allowed them to dry. By early afternoon, we began applying the first coat of A-100. Thanks to its efficient drying time, we could apply the second coat the following morning, finishing the project by early afternoon on the second day. This efficient drying time allowed us to complete the project quickly without compromising on quality, much to the homeowner’s satisfaction.

Using Sherwin-Williams A-100 Exterior Latex Paint with proper surface preparation, appropriate application techniques, and an understanding of drying times will ensure a smooth, durable, and aesthetically pleasing finish that will protect and beautify your home for years to come.
