Overview of Restorative Painting for Historic Buildings
When restoring historic buildings, using traditional painting techniques helps preserve character. Paint color and sheen are key decisions, as modern colors and high-gloss finishes often clash with period styles.
Color selection
Choosing a historic color palette is crucial. Review photos of similar buildings from the era, or look for intact, original surfaces to sample. Earth tones like tans, grays and soft greens were common, as were reds and yellows. For Victorians, deeper, richer hues were popular.
Paint type
Traditional paints like linseed oil-based provide an authentic, matte finish. Latex and acrylic are modern, so avoid them. Oil-based paint may require solvents, but provides superior coverage in fewer coats. For trim, varnishes or stains can accent woodgrain.
Application technique
Brush painting gives an authentic, hand-crafted look versus spraying. Use natural bristles; synthetics didn’t exist. ‘Cutting in’ corners and edges with a brush, then rolling larger, open areas is efficient. For trim, carefully ‘brush out’ drips and uneven areas.
Distressing techniques
Newly painted historic surfaces often look ‘too perfect’. Distressing techniques like stippling (flicking the brush at the surface), ragging (pressing a rag into fresh paint) or spattering (flicking a toothbrush at the surface) create an aged patina. Sanding edges and creating ‘wear patterns’ on floors/stairs also helps.
With the right choices in color, paint type and application technique, along with subtle aging, you’ll restore historic charm and preserve these buildings for future generations. Saving the past gives us a glimpse into the future.
Researching Original Paint Colors and Materials
Once you've decided to restore a historic building, researching the original paint colors and materials is key.
Dig into the history of the building to determine what era you want to restore to. Check old photos, records or accounts of previous renovations for clues about original color schemes. If available, analyze paint chip samples to identify exact shades. For the most accurate restoration, use period-appropriate paint types like linseed oil or milk paint.
Visit local historical societies, libraries and archives to find photos, documents or physical samples that provide context about popular paint colors and styles during your building's era. For example, bright Victorian colors were fashionable in the late 1800s, while muted earth tones were common for Arts and Crafts homes.
Check with experts on historical restoration for guidance. They can point you to resources for researching period paint palettes and ensure you avoid anachronistic color choices.
Once you've selected appropriate shades, do test patches on inconspicuous areas of the building to confirm your choices work together and suit the architectural details. You want the end result to look authentic for the time period, not just generically "old".
With the right research and expertise, you'll choose paint colors and materials that restore your historic building to its original glory. And that's worth all the effort to do it properly. After all, this building has stood the test of time - now it's your turn to faithfully preserve its history and character for generations to come.
Prepping Historic Building Surfaces for Painting
Prepping the surfaces of historic buildings requires patience and care. The key is to thoroughly clean the walls and apply a primer before painting.
Cleaning
First, wash the walls to remove any dirt or debris. Use a gentle cleaner, like diluted dish soap and water, and scrub with a soft brush. Rinse well with water to remove any remaining cleaner residue. For areas with heavy grime buildup, you may need to scrub a bit harder or use a commercial cleaner formulated for historic surfaces.
Patching Imperfections
Inspect the walls closely for any cracks, holes or imperfections and patch them. Use a sealant, putty, or drywall compound that matches your wall surface. Let all patches dry completely before priming.
Sanding
Lightly sand any remaining rough areas or imperfections. Wipe away dust with a tack cloth. Be very gentle, especially on soft or crumbling substrates like plaster. The goal is just to provide “tooth” for the primer and paint to adhere to, not change the texture of the surface.
Priming
Apply a primer designed for historic buildings. Look for a primer that contains a sealant to protect porous surfaces. For severe stains, use a stain-blocking primer. Read the product details to ensure it’s compatible with your wall material, like plaster, brick or wood. Roll or brush the primer on evenly and let it dry as directed.
Sealing
For surfaces in poor condition, it’s a good idea to apply a sealant before priming and painting. Acrylic sealants can help stabilize damaged plaster or consolidate crumbling brick and mortar. Apply as directed, then prime and paint over the sealant.
Prepping and priming historic building surfaces requires time and care but will provide a solid foundation for your new paint. With the proper cleaning, patching and priming, you’ll have surfaces ready for a fresh coat of paint that will last for years to come. Take things slowly and be gentle—your historic building will thank you for it!
Using Limewash for a Traditional Look
Limewash is a traditional paint made from limestone that is thinned with water. It creates a mottled, matte look that is ideal for historic buildings. Limewash lets the texture of the underlying surface show through, unlike modern paints that create an opaque coat.
To apply limewash, you'll need lime putty or hydrated lime, water, and natural bristle brushes. Mix the lime and water to a thin, milky consistency. Apply two or three coats, waiting for each coat to dry completely between applications. Limewash works best on porous surfaces like brick, stone, and plaster.
- Primer. For very absorbent surfaces like bare wood or drywall, apply a coat of primer first. This prevents the limewash from soaking in too quickly.
- Seal the limewash. Once the final coat is dry, apply a sealant like beeswax or linseed oil. This protects the limewash and enhances the patina as it ages. Reapply the sealant every few years.
- Consider a limewash extender. Additives like chalk, clay, and natural pigments can help adjust the color and thickness of limewash. They also make the limewash more durable.
- Protect adjacent surfaces. Limewash can damage glass, metal, and painted surfaces. Carefully mask off or shield anything you don't want to get limewash on.
- Maintain the limewash. Gently brush away any dirt or debris. Reapply limewash as needed to touch up worn or damaged areas.
Limewash creates an authentic historic look and feel. Follow these tips to successfully apply limewash to your historic building restoration project. The mottled, matte finish and breathability of limewash is perfect for old structures. With the proper maintenance and care, limewash can last for many years.
Selecting Appropriate New Paints for Old Buildings
When restoring historic buildings, selecting paints that are compatible with the existing materials is key. Modern paints contain chemicals that can damage old plaster, wood, and masonry. Instead, choose paints specifically designed for restoration projects.
Traditional paint types
For wood trim, doors, and siding, oil-based paints or alkyd paints work well. They penetrate wood and create a durable finish. For plaster walls, choose a breathable paint like limewash or milk paint. These paints won’t seal in moisture that can damage old plaster.
matching existing colors
Try to determine the building’s original paint colors. You may need to scrape away layers of paint to find them. Once you’ve found the right hue, have the paint custom-matched to the historic color.
sheen and gloss
Choose a paint sheen appropriate for the surface and time period. For example, a high-gloss paint would be out of place in an 18th-century home. A flat or eggshell sheen is more authentic for historic interiors. For trim, a satin sheen provides durability without looking too modern.
primer
Apply a primer designed for the surface you’re painting, such as an oil-based primer for wood. Priming helps new paint adhere properly to old surfaces. For significant cracks or damage in plaster or wood, use a patching compound to fill in holes and imperfections before priming and painting.
safety
Take proper safety precautions when restoring historic buildings. Old lead paint and asbestos are hazardous, so wear protective gear like respirators, gloves, and coveralls. Contain dust and debris, and thoroughly clean up the area after work is done each day.
Following these tips will help you choose paints and techniques appropriate for historic restoration projects. Take things slowly and do quality work—your building deserves the care and respect. The results will be well worth the effort.
Brushwork Techniques for Historic Paint Jobs
When restoring a historic building, brushwork techniques are key to achieving an authentic look. The right tools and methods will make a big difference in your results.
Use natural bristle brushes
Synthetic brushes can leave obvious brushstrokes, while natural bristle brushes provide a smoother finish that blends in. Hog bristle brushes are a great choice for oil-based paints. For latex paints, look for brushes specifically designed for use with latex.
Practice your technique
The secret is in the wrist. Move your entire arm in long, even strokes. Start at the top of the wall and work your way down using vertical strokes. For trim, use a smaller angled brush and take your time. Apply light, even pressure and avoid over-brushing. Wipe excess paint from the brush as needed to avoid drips.
Roll then brush
For large, flat areas like walls, use a roller to apply the bulk of the paint. Then use your brush to smooth out the texture left by the roller. Roll in one direction, then brush in the opposite direction. This provides even coverage while maintaining a natural, hand-crafted look.
Consider a stipple effect
For an aged plaster look, try stippling. Dab the brush bristles perpendicular to the surface using light, rapid strokes. Build up thin layers, letting each coat dry in between. The uneven texture will make the surface appear timeworn. Stippling works best over a slightly uneven base coat.
Glaze for depth
Applying a glaze over your topcoat is an easy way to create the appearance of age. Mix a glaze - usually a translucent paint mixed with water or a commercial glazing medium - and brush it onto trim, doors or walls. The glaze will settle into crevices, leaving the higher areas lighter. Wipe away excess with a rag for a perfectly imperfect finish.
With the right technique and tools, you'll be restoring historic homes in no time. Take your time, start with a small section, and remember that imperfections are what give historic homes character and charm. Your patience will pay off!
Common Mistakes to Avoid When Repainting Old Buildings
When restoring historic buildings, it’s easy to make mistakes that can damage the original details or character. Avoid these common pitfalls to keep your restoration authentic and preserve the building’s heritage.
Using modern paint
Don’t use regular latex or acrylic paints on old buildings. They don’t breathe like traditional paints and can trap moisture, causing wood rot and peeling. Instead, use historically-accurate paint types like limewash, milk paint or linseed oil paint. They’re porous, letting the wood breathe.
Covering up details
It may be tempting to cover intricate details like crown molding with a coat of paint for ease of application. But hiding or obscuring these features destroys the building’s character. Take time to paint carefully around trims, carvings and moldings. Use a small angled brush to get into crevices. Your patience and precision will pay off!
Selecting the wrong color
Choosing a color that’s historically inaccurate destroys the building’s authenticity. Research the time period and location of your building to determine traditional color palettes. Warm reds, forest greens and indigos were common for exteriors. Check any exposed wood for traces of the original color. You can also order paint analysis to chemically determine original colors.
Not priming properly
Proper priming is essential, especially on porous historic materials like plaster, limestone or brick. Primer seals the surface and provides tooth for the topcoat to adhere to. For the best adhesion, lightly sand the surface, wipe away dust and apply a primer suited to the substrate. Oil-based primers work well for wood. On masonry, use an alkali-resistant primer. Without priming, paint will chip and peel quickly.
Rushing the job
Take your time with each step of the restoration for the best results. Rushing leads to missed details, drips, uneven coverage and other imperfections that compromise quality. Work carefully and methodically, paying close attention to trim, ceilings, windows and doors. Multiple thin coats of paint adhere better than heavy coats. Waiting until one coat is fully dry before applying another also produces a smoother finish. Patience will reward you with a high-quality restoration.
Hiring Qualified Contractors for Historic Paint Restoration
When it comes to restoring the paint on historic buildings, hiring qualified contractors is key. These professionals have the proper training, experience, and certifications to handle paint restoration for historic properties.
Look for relevant certifications and experience
Contractors with certifications from organizations like the National Council for Preservation Education (NCPE) or the National Center for Preservation Technology and Training (NCPTT) have the necessary knowledge and skills. They should also have at least 5-10 years of experience specifically with historic building restoration. Ask to see photos of previous projects to ensure the quality of their work.
Use historically accurate paint and techniques
Qualified contractors will remove existing paint using gentle methods like chemical stripping, low-pressure abrasive cleaning or hand scraping to avoid damage. They use paints, stains and varnishes that match what was originally used. This maintains the historic integrity of the building. Techniques like graining, marbleizing and glazing can be used to recreate decorative paint finishes from the period.
Proper preparation and protection
Surface preparation is key. Contractors should thoroughly clean, patch, prime and seal any surfaces before painting. They take precautions to protect adjacent materials like glass, stone or metal from damage during the process. Covering furnishings, taping off trim, and using drop cloths are musts.
Respect the building's significance
skilled contractors understand they are working on an historic structure. They document existing conditions, choose selective paint removal methods, and aim to preserve as much original material as possible. Their goal is to restore the building’s historic character and significance. If replacement material is needed, they use in-kind materials to match the original.
Check credentials and get multiple bids
Once you’ve found qualified candidates, check their references and credentials. Get multiple bids to compare. Look for contractors that emphasize preserving your building’s historic integrity, not just completing the job quickly. With the right contractor and approach, you’ll ensure your historic building retains its character and beauty for years to come.
