Preparation
Getting your exterior walls ready for a fresh coat of paint is crucial for a long-lasting, beautiful finish. Proper preparation involves cleaning the surface to remove dirt, mildew, and loose paint, and repairing any damage to ensure a smooth, even surface for the new paint. Overlooking this step can lead to peeling, chipping, and an overall unsatisfactory result.
Surface Cleaning
Different exterior surfaces require different cleaning methods. Using the wrong technique can damage the material, so careful consideration is key.
Wood: Wood siding is susceptible to damage from harsh chemicals. A solution of mild detergent and water, applied with a soft-bristled brush, is usually sufficient. For tougher mildew stains, a mixture of one part bleach to three parts water can be effective, but always test it in an inconspicuous area first. Rinse thoroughly with clean water afterwards. Pressure washing should be avoided as it can damage the wood fibers.
Brick: Brick is a durable material, but it can accumulate dirt and grime. A pressure washer can be effective for removing loose debris, but maintain a safe distance to avoid damaging the mortar. For stubborn stains, a solution of trisodium phosphate (TSP) and water can be used, following the manufacturer’s instructions carefully. Always rinse thoroughly.
Vinyl: Vinyl siding is relatively low-maintenance. A simple wash with a garden hose and a soft brush is often enough. For tougher stains, a solution of mild detergent and water can be used. Avoid abrasive cleaners or scrub brushes, as these can scratch the surface. Pressure washing is generally acceptable for vinyl, but keep the nozzle at a safe distance.
Stucco: Stucco can be cleaned similarly to brick. A pressure washer can be effective, but use caution to avoid damaging the stucco’s surface. For stubborn stains, a solution of TSP and water can be used, following the manufacturer’s instructions. Always rinse thoroughly.
Repairing Exterior Wall Issues
Before painting, address any cracks, holes, or loose paint. Ignoring these issues will compromise the paint job’s longevity and appearance.
Cracks can be filled with caulk or patching compound, depending on their size and location. Holes require patching materials like spackle or patching compound, followed by sanding to create a smooth surface. Loose paint should be scraped away to reveal a sound surface. Always allow sufficient drying time before painting.
Patching Material Comparison
| Material | Application | Pros | Cons |
|---|---|---|---|
| Spackle | Small holes and cracks in wood, drywall | Easy to apply, dries quickly | Not suitable for large holes or exterior use in harsh weather |
| Patching Compound | Larger holes and cracks in various surfaces, including exterior walls | Durable, weather-resistant | Longer drying time, requires sanding |
| Caulk | Sealing cracks and gaps | Flexible, waterproof | Not suitable for filling large holes |
Exterior Wall Preparation Checklist
A thorough checklist ensures you haven’t missed any crucial steps. Remember that weather plays a significant role; painting in extreme heat or cold, or during rain, will negatively impact the final result.

Essential Painting Supplies
Having the right tools will make your painting project easier and more efficient. Here’s a list of essential supplies, categorized for easy reference:
| Painting Tools | Surface Protection | Safety Equipment | Other Supplies |
|---|---|---|---|
| High-quality brushes (various sizes) | Drop cloths (canvas or plastic) | Safety glasses | Paint tray |
| Rollers (various nap lengths) | Painter’s tape | Gloves | Roller extension pole |
| Putty knife | Plastic sheeting | Respirator mask (for oil-based paints) | Paint can opener |
| Stir sticks | Cardboard or newspaper | Ladder (if needed) | Cleaning rags |
Calculating Paint Quantity
Accurately estimating the amount of paint needed prevents running short or buying excessive quantities. A common method involves calculating the surface area to be painted.
The formula for calculating the surface area of a rectangular wall is:
Surface Area = Length x Height
For more complex shapes, break down the surfaces into smaller rectangles and triangles, calculating the area of each section and then summing them up.
Example: Let’s say you have a wall that’s 10 feet long and 8 feet high. The surface area is 10 ft x 8 ft = 80 square feet. Most paint cans indicate coverage per gallon (e.g., 350 square feet per gallon). To determine the number of gallons needed, divide the total surface area by the coverage per gallon: 80 sq ft / 350 sq ft/gallon ≈ 0.23 gallons.
Since you can’t buy a fraction of a gallon, you would need to purchase at least one gallon of paint for this wall. Always add extra to account for potential spills or uneven application.
Priming and Painting Techniques
Priming and painting are crucial steps in achieving a durable and aesthetically pleasing exterior house repaint. Proper preparation, including the correct application of primer and paint, significantly impacts the longevity and overall appearance of your finished project. This section details the importance of priming and explores various techniques for applying both primer and paint to ensure a professional-looking result.Primer is essential for several reasons.
Repainting your house exterior can dramatically improve its curb appeal. If you’re working with stucco, understanding the specific needs of the material is key. Check out this guide on Stucco exterior design to learn more about prepping your surface before you begin painting. Proper preparation, whether it’s stucco or another material, ensures a long-lasting, beautiful finish.
It creates a uniform surface for the paint to adhere to, improving the paint’s durability and preventing peeling or chipping. It also seals porous surfaces, blocking stains and preventing them from bleeding through the topcoat of paint. Furthermore, a good primer can enhance the paint’s color vibrancy and improve its overall coverage. Different surfaces and paint types require different primers.
For example, oil-based primers are often preferred for surfaces prone to bleeding, while acrylic primers are a more versatile and environmentally friendly option for many applications.
Primer Selection and Application
Choosing the right primer is paramount. Oil-based primers offer superior adhesion and stain-blocking properties, making them ideal for surfaces like bare wood or previously painted areas with significant imperfections or stains. However, they have a strong odor and require longer drying times. Water-based (acrylic) primers are low-odor, dry quickly, and are generally suitable for most surfaces, including wood, metal, and masonry.
Alkyd primers offer a balance between the durability of oil-based and the convenience of water-based options. Always check the primer’s label to ensure compatibility with your chosen paint type.Applying primer is similar to applying paint. For best results, apply a thin, even coat using a brush, roller, or sprayer. Allow ample drying time before painting. For larger surfaces, a sprayer is efficient, but ensure proper ventilation and wear appropriate safety gear.
For detailed areas or trim, a brush offers more control. A roller is suitable for larger, flat surfaces. Always follow the manufacturer’s instructions on drying times.
Painting Techniques
Achieving a smooth, even finish requires proper painting techniques. Using the correct tools and applying consistent pressure are crucial. For instance, using long, even strokes with a brush minimizes visible brush marks. Overlapping strokes are essential to avoid streaks. When rolling, maintain a wet edge to prevent lap marks, which are visible lines where one coat ends and another begins.
Spraying requires a steady hand and consistent distance from the surface to maintain an even coat.
Visual Guide: Correct Painting Techniques
Imagine a section of wall you are painting. Brush Technique: Visualize the brush moving in long, slightly overlapping strokes from top to bottom, maintaining consistent pressure and a smooth, even flow. Each stroke should seamlessly blend into the next, creating a uniform layer of paint. Avoid short, choppy strokes, which can leave visible brush marks. Roller Technique: Picture the roller moving in a “W” pattern, covering the entire area with even pressure.
Maintain a wet edge to prevent lap marks. The roller should be fully saturated but not dripping, ensuring consistent paint application. Spray Technique: Imagine the spray gun moving smoothly and at a consistent distance from the surface. Maintain a steady speed and avoid lingering in one spot, which can cause runs or drips. The spray pattern should be even and consistent, creating a smooth, uniform layer of paint.
Safety Precautions
Always wear appropriate safety gear, including gloves, eye protection, and a respirator, especially when working with oil-based products or sprayers. Ensure adequate ventilation, and never work in confined spaces without proper ventilation. Follow all manufacturer instructions on paint and primer application and cleanup. Dispose of paint and cleaning materials responsibly according to local regulations.
