How to Use Chemical Strippers:
1. Choose the Right Product: Look for a paint stripper specifically designed for masonry.
2. Prepare the Area: Cover surrounding surfaces with plastic sheeting to protect them from drips.
3. Apply the Stripper: Use a brush to apply a thick layer of stripper to the painted area.
4. Wait: Allow the stripper to sit as per the manufacturer’s instructions, usually 15-30 minutes.
5. Scrape Off the Paint: Use a stiff brush or scraper to remove the paint.
6. Rinse: Thoroughly rinse the area with water to remove any residue.
2. Pressure Washing
Pressure washing is a popular method for removing paint from brick, especially for exterior surfaces.
Pros:
Cons:
How to Use a Pressure Washer:
1. Choose the Right Pressure: Start with a lower pressure setting (around 1500-2000 PSI).
2. Prepare the Area: Remove any nearby items and cover plants or surfaces that could be damaged by water.
3. Test a Small Area: Always start with a small, inconspicuous area to gauge the effectiveness and adjust the pressure accordingly.
4. Wash the Surface: Hold the nozzle at a 45-degree angle and wash the surface in even strokes.
3. Sandblasting
Sandblasting involves using high-pressure air to propel abrasive materials against the surface of the brick to remove paint.
Pros:
Cons:
How to Use Sandblasting:
1. Hire a Professional: Due to the complexity and potential for damage, it’s often best to hire a professional service.
2. Protect Surrounding Areas: Sandblasting creates a lot of dust, so cover nearby surfaces and vegetation.

How to Use a Heat Gun:
1. Set the Temperature: Choose a medium setting (around 500°F).
2. Work in Sections: Hold the heat gun a few inches away from the surface and move it back and forth.
3. Scrape Off Paint: Once the paint bubbles and softens, use a scraper to remove it.
4. Clean Up: After the paint is removed, clean the surface with water.
5. Baking Soda Blasting
Baking soda blasting is an eco-friendly alternative to sandblasting, using baking soda as the abrasive medium.
