Painting floor screed can be a cost-effective and durable way to improve the appearance of your floors, especially in garages, basements, or utility spaces. Floor screed is typically made of cement and sand, providing a smooth, hard surface. However, to ensure a long-lasting finish, proper preparation and the right materials are essential. In this guide, we’ll walk you through how to successfully paint floor screed and achieve a professional finish.
What You’ll Need:
- Paint suitable for concrete/screed (epoxy or polyurethane are best)
- Concrete primer
- Roller and paint tray
- Paintbrush (for edges and corners)
- Masking tape
- Sandpaper (medium to fine grit)
- Vacuum or broom
- Mop and bucket
- Protective gloves and mask
- Floor cleaner or degreaser
Step 1: Prepare the Screed Surface
Before you start painting, it’s crucial to prepare the screed surface properly. Any dust, dirt, or grease on the floor will prevent the paint from adhering correctly.
- Clean the Surface: Sweep the floor thoroughly to remove any dust and debris. Follow up with a vacuum for any remaining fine particles.
- Degrease the Floor: If the screed is in an area that has been exposed to oil or grease, use a degreasing agent to clean the surface. Scrub it well and then mop the floor with clean water. Let it dry completely before moving to the next step.
- Sand the Screed: Using medium-grit sandpaper, lightly sand the screed to create a slightly rough surface. This helps the primer and paint adhere better. After sanding, vacuum up the dust.
Step 2: Apply the Primer
Priming is essential for ensuring the paint bonds well to the floor screed, especially since screed is porous and can absorb moisture.
- Choose the Right Primer: Select a concrete or screed-specific primer. Epoxy-based primers work particularly well as they seal the surface and provide excellent adhesion.
- Apply the Primer: Use a roller to apply a thin, even coat of primer across the entire surface. Start from the farthest corner and work your way towards the exit. Use a brush to reach edges and corners. Let the primer dry for the recommended time (usually 4-6 hours or as advised by the product instructions).
Step 3: Paint the Floor
Once the primer has dried, it’s time to apply the paint.
- Choose Your Paint: For screed floors, epoxy or polyurethane-based paints are ideal as they are durable, resistant to wear and tear, and easy to clean. Choose a colour that suits your space or even consider an anti-slip finish if needed.
- Start Painting: Pour the paint into a tray and use a roller to apply the first coat evenly. Start at the farthest corner and work your way to the exit, just as you did with the primer. Use a paintbrush for edges and any hard-to-reach spots.
- Apply a Second Coat: For a more durable finish, apply a second coat of paint after the first coat has completely dried. This will ensure that the floor is fully protected and the colour is uniform.
Step 4: Finishing Touches
After the second coat has dried, inspect the floor for any missed spots or uneven patches. If necessary, touch up the areas with a small brush.
- Allow for Full Curing:While the paint may feel dry to the touch after 24 hours, it’s best to wait 5-7 days before placing any heavy furniture or equipment on the floor to allow the paint to cure fully.
- Maintain the Painted Floor: Keep your newly painted screed floor in good condition by cleaning it regularly. Avoid using harsh chemicals that could damage the paint and opt for gentle cleaners.
In Summary
Painting a screed floor can be a simple yet transformative DIY project when done correctly. By properly preparing the surface, applying a good quality primer, and using durable paint, you’ll ensure a long-lasting, professional-looking finish that can enhance the appearance and functionality of your space. Whether it’s a garage, utility room, or industrial area, a painted screed floor adds a fresh, polished look while also offering durability and protection.
