Restoring painted brickwork back to its original character is one of the most rewarding yet challenging home restoration projects. Over decades, brick fireplaces, exterior walls, and garden pillars accumulate thick paint layers that mask the original texture beneath. Stripping these layers to expose raw masonry requires disciplined preparation. Dry scraping or sanding struggles to reach deep masonry pores and can gouge brick faces. Achieving a clean, restored finish requires choosing a specialised system that lifts paint safely without damage.
For ninety years, Haymes Paint has helped Australians master complex surface preparation. Founded in Ballarat in 1935, our family-owned brand is now guided by its fourth generation of paint experts.

Read our process to strip old paint safely, preserve the masonry, and prepare the surface for a beautiful raw appearance or a highly durable new paint system.
Structural challenges of brick and masonry restoration
Brickwork and masonry are fundamentally different from flat plasterboard or smooth timber surfaces. Clay bricks and stone are highly porous, possessing microscopic pockets that draw liquid paint deep into the substrate. Mortar joints, which hold the masonry together, are even more textured and absorbent. Because paint penetrates deep, anchoring itself inside the brick face and the surrounding mortar, standard hand scraping or conventional dry sanding is highly ineffective. Mechanical tools cannot reach into these deep recesses. Attempting to force scrapers into crevices chips brick faces and ruins fine masonry details, while sanding generates hazardous dust and clogs sheets. Non-destructive paint removal systems are essential to clear the pores completely.
Inspecting your brickwork and existing paint before starting
Evaluating structural health is a mandatory first step. Inspect the surface for spalling, where brick faces flake or disintegrate, and check if mortar lines are soft or sandy, as weak mortar will wash away during rinsing and require repointing.
Safety is paramount; masonry painted before 1970 is highly likely to contain toxic lead pigments. Dry sanding, wire wheeling, or scraping lead-based paint releases hazardous dust. Wet chemical stripping is the recommended, lead-safe method for removing paint from historical brickwork because it keeps paint layers wet and bound, preventing airborne dust.
Deciding whether to strip back to bare brick or repaint
Complete paint stripping is not always necessary. If your existing paint is structurally sound and you simply wish to update the colour, repainting the surface is often the most practical decision. To determine if the current paint layers can safely support a new topcoat, conduct two simple professional diagnostic tests.
The first is the adhesion test. Lightly cut an 'X' into the existing paint using a utility knife. Firmly apply adhesive tape across the cut and pull it off sharply. If any paint flakes adhere to the tape, the existing paint lacks structural integrity, making complete stripping mandatory. The second is the compatibility test. Sand and clean a small, inconspicuous area. Apply one coat of your desired topcoat and allow it to dry for twenty-four hours. Perform another adhesion test on this new paint. If it pulls off, the old and new paints are incompatible, requiring complete removal.
Selecting a safe paint stripping method for porous masonry
Selecting the wrong removal method can cause permanent damage to historical brickwork. Many homeowners make the destructive mistake of using aggressive mechanical techniques like sandblasting, high-pressure washing, or wire wheels. Brick is manufactured with a hard outer layer known as the fire-skin, which is created in the kiln during production. This fire-skin provides a dense, protective barrier that shields the soft, porous interior of the brick from water penetration.
Aggressive blasting strips away this vital protective fire-skin, exposing the soft clay beneath. Once the fire-skin is destroyed, the bricks absorb rainwater, leading to dampness, salt damage, and crumbling masonry. High-pressure washing will also disintegrate mortar joints, destabilising the wall. Non-destructive chemical paste systems are the safest option for textured masonry. Specialised paint removal systems, such as Peel Away, use a thick, alkaline paste covered with a protective paper blanket that keeps the paste wet and active to penetrate deep into porous brick crevices and mortar joints, safely liquefying and lifting multiple paint layers in a single clean step.
How to apply and remove Peel Away on brickwork and masonry
Successful paste-and-blanket paint removal requires adhering to technical parameters. Because brick porosity and paint types vary, a small trial test patch is mandatory before starting. This determines the required paste thickness (one to three millimetres) and optimal dwell time (two to twenty-four hours).
Begin by preparing your work area and securing your personal safety. Ensure the masonry surface is dry and free of loose dirt. Cover adjacent floors and non-target surfaces with heavy-duty plastic sheeting to protect them from splashes. Put on heavy-duty chemical-resistant gloves, safety goggles, and protective clothing.
Apply the alkaline paste thickly using a spatula or trowel, working it into mortar joints and textured crevices. Press the protective paper blanket firmly onto the wet paste, smoothing out air bubbles to seal the system. After the required dwell time, slide a flat scraper under the blanket, lifting the softened paint, paste, and blanket off in sheets. Place waste into secure bags for proper disposal, and remember to recycle your empty cans and dispose of leftover paint safely through chemical waste collection programs like Paintback.
Managing expectations for the look of restored bare brickwork
Stripping decades of old paint back to bare brick is an authentic restoration method, but it will not return historic masonry to a uniform, pristine, "as new" appearance. Historic brickwork carries organic character, and decades of weathering and paint contact leave permanent marks on the substrate.
You should expect some minor paint residues to remain locked deep within the microscopic pores of the brick and the textured crevices of the mortar joints, adding historic charm and a rustic, authentic aesthetic. Many historic brick walls were originally painted to cover up structural stains, mismatched replacement bricks, or repairs. Stripping the paint will expose these historical modifications, revealing the true narrative of the building. Understanding these physical realities ensures you can appreciate the unique character of bare masonry once the stripping process is finished.
Cleaning and preparing your masonry after paint removal
Paint stripping is only half the battle; the newly exposed masonry must be clean and dry before applying any finish. Wash the bare masonry thoroughly with clean water and a stiff bristle brush to scrub away residues, ensuring pores are completely clear. Rinsing introduces a substantial volume of water. Painting over trapped moisture causes severe bubbling, blistering, and immediate adhesion failure.
To verify that your brickwork is completely dry, perform a simple plastic sheet moisture test. Tape a 300mm square piece of clear plastic over multiple areas of the bare masonry, sealing all edges tightly. Leave for at least two hours. If condensation forms under the plastic, or if the masonry darkens, the wall contains excess moisture and needs further drying. If using a moisture metre, the reading must be below 14% before proceeding. Newly repaired mortar joints or concrete must cure for 28 days and be washed with sugar soap before finishing.
Choosing between a bare brick finish and a fresh paint system
Once your brickwork is clean, dry, and structurally sound, decide on the final aesthetic direction. Some renovators prefer to leave the raw brick bare to highlight its heritage beauty, while others opt to repaint the masonry using a modern paint system. Before making your final colour decision, you can explore our colour families and order swatches online to find the perfect shade for your project.
If repainting interior brickwork, proper sealing is essential. Apply one coat of Acrylic Sealer Undercoat to seal bare brickwork and mortar, providing a uniform foundation. To complete your interior paint system, you can view our Interior Expressions® range which offers a 99% volatile organic compound-free formulation and a 7-year mould growth guarantee, or choose Ultra Premium Coverplus Interior paint.
For exterior masonry walls, fences, or pillars, apply one coat of Acrylic Sealer Undercoat to block suction. You can also explore our Exterior Solashield® range of exterior paints, which utilise Surface Lock Technology to resist dirt and offer a twenty-year guarantee against peeling, blistering, and flaking on correctly prepared surfaces.
Pitfalls to avoid during masonry restoration
Steering clear of common errors is the best way to safeguard your property and ensure a long-lasting finish. First, never skip the trial test patch. Skipping it often leads to applying paste too thin, resulting in incomplete softening, or leaving it on too long, causing the paste to dry hard and bond permanently.
Second, avoid using wire wheels, sandblasting, or high-pressure washers on brickwork, as these mechanical methods destroy the protective kiln-fired skin of the brick and disintegrate fragile mortar joints, leading to structural instability and water damage.
Third, never repaint brickwork that has not dried completely. Trapping water inside porous masonry under a cured paint film will cause severe blistering, flaking, and paint failure within weeks. Taking the time to execute each phase of preparation systematically ensures your brickwork remains beautiful and structurally sound for decades.
