Categories: Barrettine, Products
When undertaking any renovation project, trade professionals and DIY enthusiasts are likely to come across old paint that needs removing. Removing paint from walls can be a challenging task, but with the right products and techniques, you can achieve the right results.
At Barretine, we have over 145 years of experience in formulating and providing premium chemical products, and we have put together this comprehensive guide to help you effectively remove paint from various wall surfaces.
Understanding wall and paint types
Before you begin any paint removal project, it's crucial to identify both your wall surface and the type of paint you're dealing with. Different surfaces - from plaster walls to masonry - require specific approaches and understanding. Plaster walls, for instance, need gentle handling to prevent damage to the underlying surface, whilst brick or masonry can withstand more robust treatment.
The type of paint you're removing is equally important; oil-based, water-based, and lead-based paints all respond differently to various removal methods.
Oil-based paint is known for its durability and typically requires more robust removal methods, often requiring chemical strippers.
For older properties, particularly those built before the 1970s, there's a significant possibility of lead-based paint, which requires special handling and safety precautions. In these cases, professional testing is recommended before proceeding with any removal work. Lead paint removal must be handled with extreme care to prevent harmful dust and particles from becoming airborne. If you are a homeowner, always consult a professional to remove lead-based paint.
Safety first: essential preparation
Safety should always be your primary concern when undertaking any paint removal project.
Removing layers of paint from walls can generate dust, fumes, and potentially harmful debris, making protective equipment essential.
Protective gear
Personal protection is vital. A proper dust mask or respirator is essential to prevent the inhalation of paint particles and chemical fumes. Safety goggles will protect your eyes from loose paint chips and splashes, while heavy-duty gloves are necessary to shield your hands from chemicals and sharp scraping tools. Long-sleeved clothing and closed-toe footwear provide additional protection.
Ventilation
Ensure that your workspace is properly prepared. This means thoroughly ventilating the area by opening windows and, if possible, using fans to create airflow.
Room preparation
Begin by removing all furniture from the room. If this isn't possible, move items to the centre and cover them with plastic sheeting. Cover floors with drop cloths or dust sheets, securing them with tape to prevent slipping. Remove or protect fixtures and fittings, including light switches, outlet covers, and any decorative elements that cannot be removed.
Choosing the right product
Barrettine offers several specialist solutions for different paint removal scenarios, each designed to tackle specific challenges.
This powerful formula is specifically designed for heritage restoration projects and properties with multiple layers of old paint.
It's particularly effective at removing toxic lead paint from ornate plaster ceilings and cornices, capable of stripping up to 32 layers in a single application.
The alkaline formulation safely neutralises lead content, making disposal safer and more environmentally responsible. It's ideal for professional restorers working on period properties where preserving architectural details is crucial.
Our modern paint removal solution, Peelaway 7, offers exceptional performance on contemporary paint systems.
It's particularly suitable for domestic and industrial applications where a gentler approach is needed. The non-caustic formula works effectively on sensitive surfaces like veneer and plywood, making it perfect for detailed restoration work. Its low-odour formulation makes it ideal for indoor use, and its naturally degradable composition offers environmental benefits.
This versatile paint stripper excels in situations requiring quick results on vertical surfaces.
Its unique gel formula clings to surfaces, preventing drips and ensuring even coverage.
Paint Panther is particularly effective on metallic and hammer-type paints, making it perfect for smaller projects like doors, furniture, and architectural details.
What's the difference between Peelaway 1 and Peelaway 7?
Peelaway 1 is specifically formulated for older, oil-based and lead-based paints, making it the go-to choice for period properties and heritage restoration. It’s poultice system not only seals in the product to maintain its effectives but also allows safer removal and clean up once the stripping process has been completed. Peelaway 1 will require neutralisation of the surface once stripped to stop the chemical process and allow new paint to adhere to the surface once dry and at the correct pH level. Peelaway 7, on the other hand, is engineered for modern paint systems. Its non-caustic formula eliminates the need for neutralisation and makes it particularly suitable for contemporary applications and sensitive surfaces.
The importance of patch testing
Before undertaking any large-scale paint removal, conducting a test patch is absolutely essential. Choose an inconspicuous area and apply your chosen paint stripper product.
This test will help determine the optimal product, application thickness, and dwell time for your specific situation. It's also crucial for identifying any potential adverse reactions with the underlying surface.
How do I need to prepare the surface for paint removal?
Begin by thoroughly inspecting the wall surface for any loose or flaking paint. Using a paint scraper or stiff brush, carefully remove any loose material, working slowly to avoid damaging the wall.
Step-by-step paint removal process
The process for removing paint from walls using Peelaway or Paint Panther varies depending on which product you are using.
For Peelaway products:
Peelaway’s unique poultice method allows for deep penetration into multiple paint layers, making it an excellent choice for thorough paint removal.
The application process begins with mixing the paste if required. Apply the product evenly across the surface using the provided spatula, or a brush if easier, maintaining a consistent thickness as determined by your test patch.
Cover the applied paste with the special Peelaway blanket (the Peelaway 1 blanket is red, the Peelaway 7 blanket is green), ensuring good contact. These blankets are crucial for the system's effectiveness, trapping moisture and allowing the product to work efficiently. They also allow a easier clean up as the stripped paste and paint can be placed inside and deposited.
Allow the product to dwell for as long as your test patch has determined (each project will vary; this is why a test patch is so crucial to do before starting the removal process) then carefully begin by peeling to remove the blanket along with the stripped paint and clean any residue from the surface.
For Peelaway 1, use the supplied neutraliser after removing all coatings from the wall or surface. For Peelaway 7, clean the stripped surface with water using a sponge, scrubbing brush or wet/dry vacuum. Avoid soaking the substrate or wetting for prolonged periods and allow stripped surface to dry thoroughly (no neutralisation is required).
For Paint Panther:
Paint Panther offers a highly effective solution for smaller projects or when precision is key. This gel-based paint remover is designed for quick action and ease of use.
Apply the gel formula generously to the surface using a brush, working in manageable sections and ensuring even coverage. The specialised gel consistency allows it to cling effectively to vertical surfaces without dripping.
Allow the product to work for 10-20 minutes. You'll notice the paint beginning to bubble or lift.
Use a scraper or putty knife to remove the softened paint, working in consistent strokes.
Clean-up and wall preparation
Multiple applications might be necessary for particularly stubborn areas or numerous paint layers. Rather than attempting to remove everything in one go, which might risk damaging the underlying surface, plan for a methodical approach with repeated gentle applications if required.
After the bulk of the paint has been removed, thorough cleaning is essential, especially if you are planning on applying new paint. For Peelaway 1, neutralisation is crucial - apply the supplied neutraliser and test the pH level to ensure it falls between 5-9. With Peelaway 7, thoroughly clean the surface with water using a sponge, scrubbing brush or wet/dry vacuum, avoid soaking the substrate or wetting for prolonged periods, and Paint Panther wipe the surface clean with Barrettine White Spirit or Methylated spirits. Allow the wall to dry completely before assessing the surface for any remaining paint or necessary repairs.
