Dryvit, a popular type of Exterior Insulation and Finish System (EIFS), offers excellent insulation and a versatile aesthetic. However, over time, Dryvit can become stained, faded, or simply outdated, prompting homeowners to consider painting it. Painting Dryvit is possible and can significantly enhance your home’s curb appeal, but it requires careful preparation, the right materials, and a proper application technique. This comprehensive guide will walk you through each step, ensuring a successful and long-lasting paint job.
Understanding Dryvit and its Unique Properties
Before you even think about picking up a brush, it’s crucial to understand what Dryvit is and how it differs from traditional siding materials like wood or stucco. Dryvit, and EIFS in general, is a multi-layered system typically consisting of insulation board (usually expanded polystyrene or EPS), a reinforced base coat, and a textured finish coat. This system is designed to be flexible and breathable, allowing moisture to escape while providing excellent thermal performance.
The key to painting Dryvit successfully lies in respecting these properties. Using the wrong type of paint can trap moisture, leading to blistering, cracking, and even structural damage. Likewise, improper preparation can compromise the integrity of the finish coat.
Identifying the Type of Dryvit
While most Dryvit systems appear similar, there can be slight variations in the finish coat’s texture and composition. Identifying the specific type of Dryvit on your home can help you choose the most appropriate primer and paint. Look for any existing documentation from when the system was installed. If you can’t find any, contacting a Dryvit professional for identification is recommended. This can prevent potential compatibility issues down the line.
Preparation is Key: Cleaning and Repairing the Surface
Proper preparation is arguably the most important step in painting Dryvit. A clean, sound surface is essential for achieving good adhesion and a durable finish. Skimping on preparation will likely result in premature peeling, cracking, and disappointment.
Thorough Cleaning: Removing Dirt, Mold, and Mildew
Begin by thoroughly cleaning the Dryvit surface to remove any dirt, dust, mildew, or algae. Use a pressure washer with a wide fan tip and a low to moderate pressure setting to avoid damaging the finish coat. Avoid using a concentrated, high-pressure stream, as this can etch or even puncture the Dryvit.
For stubborn stains, mold, or mildew, use a solution of water and a mild detergent or a specialized mildew cleaner. Apply the solution with a soft-bristled brush and scrub gently. Rinse thoroughly with clean water. Allow the Dryvit to dry completely before proceeding to the next step.
Repairing Cracks and Damage
Carefully inspect the Dryvit surface for any cracks, holes, or other damage. Small hairline cracks are common and can often be filled with a flexible acrylic caulk specifically designed for EIFS. Apply the caulk evenly and smooth it out with a putty knife.
Larger cracks or holes may require more extensive repairs. Consult with a Dryvit professional to determine the best course of action. In some cases, patching with EIFS base coat and mesh may be necessary. Ensuring the repairs are flush with the existing surface is crucial for a seamless paint job.
Masking and Protecting Surrounding Areas
Before you start priming and painting, take the time to mask off any areas you don’t want to paint, such as windows, doors, trim, and landscaping. Use high-quality painter’s tape and plastic sheeting to protect these surfaces. Careful masking will save you time and effort in the long run.
Choosing the Right Primer and Paint
Selecting the correct primer and paint is critical for a successful and long-lasting paint job on Dryvit. The ideal products will adhere well to the existing surface, provide a durable finish, and allow the Dryvit to breathe.
Primer Selection: Ensuring Adhesion and Uniformity
Always use a high-quality, breathable primer specifically designed for EIFS. An acrylic latex primer is generally a good choice. The primer’s main job is to create a uniform surface for the paint to adhere to, while also sealing any minor imperfections.
Apply the primer evenly using a brush, roller, or sprayer. Follow the manufacturer’s instructions for application rates and drying times. Make sure the primer is completely dry before applying the first coat of paint. Tinting the primer to a similar color as the topcoat can improve coverage and reduce the number of paint coats needed.
Paint Selection: Breathability and Durability are Key
For the topcoat, use a high-quality, breathable acrylic latex paint specifically formulated for exterior use. Avoid oil-based paints or paints that are not breathable, as they can trap moisture and cause problems. Choose a paint with excellent UV resistance to prevent fading and chalking.
Consider the desired sheen level. A flat or matte finish will help to hide imperfections and provide a more natural look, while a satin or eggshell finish will be easier to clean and offer better stain resistance. However, higher sheen levels can accentuate imperfections.
Always read the manufacturer’s instructions carefully before applying any paint. Pay attention to recommended application temperatures and drying times.
The Painting Process: Applying the Paint for a Professional Finish
With the surface properly prepared and the right materials chosen, it’s time to start painting. Applying the paint correctly will ensure a professional-looking finish that will last for years to come.
Application Techniques: Brush, Roller, or Sprayer?
There are three main methods for applying paint to Dryvit: brush, roller, and sprayer. Each method has its advantages and disadvantages.
- Brush: Brushing is best for small areas, detailed work, and cutting in around windows and doors. It provides excellent control and allows you to work the paint into the textured surface of the Dryvit.
- Roller: Rolling is a good option for larger areas and can be faster than brushing. Use a roller with a nap length appropriate for the texture of the Dryvit. A longer nap will be needed for more heavily textured surfaces.
- Sprayer: Spraying is the fastest method for covering large areas and can provide a very even finish. However, it requires more skill and preparation, including masking off surrounding areas to prevent overspray. An airless sprayer is generally the best choice for painting Dryvit.
Consider these factors when choosing your application method.
Applying Multiple Coats: Achieving Full Coverage and Durability
Apply at least two coats of paint to ensure full coverage and durability. Allow each coat to dry completely before applying the next. Follow the manufacturer’s recommended drying times. Applying multiple thin coats is better than applying one thick coat, which can lead to runs, drips, and uneven drying.
Back Rolling: Forcing Paint into Textured Surfaces
If you are using a sprayer, consider back rolling the paint immediately after spraying. This involves using a roller to work the paint into the textured surface of the Dryvit, ensuring better adhesion and coverage. Back rolling is especially important for heavily textured Dryvit.
Post-Painting Care and Maintenance
Once the painting is complete, proper care and maintenance will help to extend the life of your paint job and keep your Dryvit looking its best.
Regular Cleaning: Preventing Dirt and Stains
Regularly clean the Dryvit surface to remove dirt, dust, and other debris. Use a garden hose with a gentle spray nozzle or a soft-bristled brush and a mild detergent. Avoid using harsh chemicals or abrasive cleaners, as these can damage the paint finish.
Inspecting for Damage: Addressing Issues Promptly
Periodically inspect the Dryvit surface for any signs of damage, such as cracks, blisters, or peeling paint. Address any issues promptly to prevent them from worsening. Small repairs can often be made with caulk or touch-up paint.
Re-Painting: Maintaining a Fresh Look
Depending on the climate and the quality of the paint used, you may need to re-paint your Dryvit every 5-10 years to maintain a fresh look and protect the underlying system. When re-painting, follow the same preparation and application steps as outlined above.
Troubleshooting Common Problems
Even with careful preparation and application, some problems can still occur when painting Dryvit. Here are some common issues and how to address them.
Peeling Paint: Identifying the Cause and Finding Solutions
Peeling paint is a common problem that can be caused by several factors, including poor surface preparation, moisture trapped behind the paint, or using the wrong type of paint.
If the paint is peeling, remove any loose or flaking paint with a scraper or wire brush. Clean the surface thoroughly and allow it to dry completely. Apply a coat of primer and then re-paint with a high-quality, breathable acrylic latex paint.
Blistering Paint: Addressing Moisture Issues
Blistering paint is usually caused by moisture trapped behind the paint film. This can be due to a leak in the Dryvit system, condensation, or using a non-breathable paint.
To fix blistering paint, identify and address the source of the moisture. Remove any loose or blistered paint. Allow the surface to dry completely. Apply a coat of primer and then re-paint with a breathable acrylic latex paint.
