Using Masonry Paint Stripper

Follow this comprehensive guide to effectively strip masonry paint and restore your walls to their original condition

How to Use Masonry Paint Stripper – A Step-by-Step Guide

Health and Safety First

Paint stripping can be a messy and demanding task, so it’s essential to take proper precautions. Biostrip Plus is an eco-friendly, non-toxic solution, it still contains active chemicals that should be handled with care.

• Wear protective gloves and safety goggles to avoid skin and eye irritation.

• Wash hands thoroughly after use to remove any residue.

• Avoid contact with garden ponds or aquatic life, as even biodegradable solutions can impact delicate ecosystems.

• Ensure good ventilation if working in enclosed spaces.

Full Guide to Stripping Masonry Paint

Step 1: Remove Loose and Flaking Paint

Before applying any chemical stripper scrape away any peeling or flaking paint using a putty knife or scraper.

Top Tip: Avoid harsh methods like sandblasting or wire brushing, as these can damage masonry, making it more porous and susceptible to water damage.

Step 2: Clean Fungus and Algae

Outdoor surfaces exposed to moisture often develop fungus, mold, or algae, which can interfere with paint stripping.

• Apply a fungicidal wash or algae cleaner to the affected areas.

• Allow at least 24 hours for the treatment to work before proceeding.

Step 3: Apply Biostrip Plus Masonry Paint Stripper

Using an old paintbrush, apply Biostrip Plus generously over the surface.

• Work in small sections to ensure even coverage and better control.

• Allow at least one hour for the product to penetrate and soften the paint.

• Colder temperatures may extend the softening time, so be patient and check periodically.

Step 4: Let the Stripper Work

Once the paint begins to soften, leave Biostrip Plus in place until the entire layer becomes loose and easy to remove.

• Avoid excessive scrubbing – softened paint should lift off with minimal effort.

• For multiple paint layers, a second application may be required.

• Cover the treated area with polythene or cling film. This helps to prevent the Biostrip Plus from drying out and encourages a faster strip time.

Step 5: Remove Stripped Paint

Once the paint has sufficiently softened:

• Use a scraper to gently remove the paint from the surface.

• For stubborn areas, a second application of Biostrip Plus may be necessary.

• If needed, a stiff brush can help remove paint from textured surfaces.

Step 6: Wash and Rinse the Surface

After stripping is complete, thoroughly rinse the area using a pressure washer or garden hose.

• For delicate masonry, use a lower pressure setting to avoid damage.

• Allow the wall to dry completely before repainting, sealing, or refinishing.

Additional Tips for Best Results

• Work in dry conditions – Applying Biostrip Plus in wet or humid weather may reduce effectiveness.

• Use plastic sheeting – Cover areas you don’t want to strip to avoid accidental damage.

• Test on a small area first – This helps gauge the reaction time and effectiveness before treating a large surface.
