How to Paint a Concrete Floor: A Step-by-Step Guide for UK Homes and Businesses
Introduction
Painting a concrete floor is a cost-effective way to transform dull, grey surfaces into durable, attractive, and easy-to-maintain spaces. Whether it’s a garage, workshop, warehouse, retail space, factory floor, or hospitality venue, the right preparation and paint selection are key to achieving durable and professional results tailored to high-traffic business environments.
In this step-by-step guide, we’ll show you how to prepare, paint, and finish concrete floors to ensure longevity and a stunning finish. At Specialist Paints Online, we stock high-quality concrete floor paints designed for UK homes and businesses.
Why Paint Your Concrete Floor?
Painting concrete floors provides significant benefits for businesses across various industries:
Enhanced Professional Appearance: Adds colour and style to garages, factories, warehouses, retail spaces, and hospitality venues, creating a polished and welcoming environment.
Unmatched Durability: Protects floors from cracks, stains, and heavy wear caused by machinery, vehicles, or foot traffic in high-demand areas.
Simplified Maintenance: Smooth, sealed surfaces are easier to clean, saving time and reducing maintenance costs in busy spaces like workshops or restaurants.
Improved Safety Standards: Anti-slip coatings enhance traction in high-traffic or spill-prone areas, ensuring compliance with workplace safety regulations.
Cost-Effective Solution: A fresh coat of paint is an affordable way to extend the life of your floors, minimise downtime, and improve overall property value.
Choosing the Right Product for Your Needs
Selecting the right product for your concrete floor is essential, as it not only ensures you achieve your desired outcome but also determines the application method required. Factors like:
Purpose of the Floor: Consider how the space will be used—light traffic areas may need quick-drying acrylics, while heavy-use spaces like warehouses require durable 2-pack epoxy.
Type and Condition of the Substrate: Is the concrete new, aged, or previously painted? The surface’s condition will determine the need for primers or additional preparation.
Traffic and Durability Needs: High-traffic areas or spaces exposed to machinery demand paints with superior durability and abrasion resistance.
Safety Requirements: Anti-slip coatings are essential for wet or spill-prone environments to ensure safety compliance.
Aesthetic Preferences: Choose colours and finishes that align with your design goals, whether glossy, matte, or textured.
Budget and Longevity: Balance upfront costs with long-term savings. Premium options like epoxy may cost more initially but offer extended durability and reduced maintenance.
Understanding these factors will help you select the ideal product to meet your floor’s specific requirements. At Specialist Paints Online, we provide expert advice to guide you every step of the way.
What You’ll Need to Paint a Concrete Floor
Before you get started, gather the following tools and materials:
- Concrete Floor Paint: Choose durable options like 2-pack epoxy paints or single-pack acrylics.
- Primer: A primer ensures better adhesion, especially for porous or previously untreated surfaces.
- Paint Supplies:
- Paint roller with extension handle
- Brushes for edges
- Paint tray
- Surface Preparation Tools:
- Broom or vacuum
- Degreaser or cleaning solution
- Concrete filler for cracks
- Sandpaper or floor grinder (if necessary)
- Safety Equipment: Gloves, goggles, and a dust mask.

Step 1: Prepare the Concrete Surface
Proper preparation is essential for a smooth, long-lasting finish. Follow these steps:
- Clean the Surface:
- Sweep the floor to remove dust and debris.
- Use a degreaser to clean oil stains, grease, or contaminants like Coo-Var Oil Remover. For stubborn stains, scrub with a stiff brush and rinse with water.
- Repair Cracks and Damage:
- Use a concrete filler to repair any cracks or holes. Allow it to dry fully before sanding for a smooth finish.
- We recommend Coo-Var Floor Pack Repair Mortar or for cold environment repairs Coo-Var Cold Storage Repair Mortar.
- Remove Existing Coatings:
- If there’s old, peeling paint, remove it using a scraper, sander, or concrete grinder.
- Test for Moisture:
- Take a moisture reading or Lay a sheet of plastic on the floor and tape it down. Leave for 24 hours—if condensation appears underneath, address the moisture issue before painting.
- Etch the Surface (Optional):
- For smooth, untreated concrete, use an etching solution like Coo-Var Acid etch floor cleaner to roughen the surface and improve paint adhesion.
Step 2: Apply a Primer
Priming helps seal the concrete and ensures your paint adheres evenly.
- Choose the Right Primer: Selecting the appropriate primer depends on the substrate and the paint you plan to use, such as water-based or epoxy primers for concrete floors.
- Damp Substrates: For newly poured concrete, substrates without a damp-proof membrane, or those with a moisture reading of 14% or higher, Coo-Var Dampshield Primer Two-Pack Resin Based Epoxy Primer should be applied to allow moisture to release naturally without compromising the integrity of the paint coating. Note- Coo-var ProFloor Plus must be used when overcoating.
- Application:
- Apply the primer evenly with a roller.
- Allow it to dry for the recommended time before proceeding.
Pro Tip: Priming is especially important for high-traffic areas or surfaces exposed to moisture.
Step 3: Choose the Right Concrete Floor Paint
As mentioned above, choosing the right product is essential to achieving the best results. Often, the intended use and traffic levels of the floor are key factors in determining the most suitable paint:
- 2-Pack Epoxy Floor Paint:
- Best for garages, workshops, and industrial spaces.
- Offers superior durability, chemical resistance, and long-lasting results.
- Acrylic Floor Paint:
- Ideal for low-traffic areas like patios, basements, or residential spaces.
- Quick-drying and easy to apply.
- Anti-Slip Floor Paint:
- Perfect for wet or hazardous areas like kitchens, walkways, or gyms.
- Specialist paints online stocks both Pre-Aggregated products or Anti-Slip Aggregate to add in.

Step 4: Apply the Concrete Floor Paint
Apply the chosen paint following the requirements outlined on the tin and the technical data sheet to ensure optimal results. For tailored application advice, contact the experts at Specialist Paints Online.
General Example:
- Stir Thoroughly: Ensure the paint is mixed well before application. For 2-pack epoxy, mix the resin and hardener as instructed.
- Cut in the Edges: Use a brush to paint around the edges and corners of the floor.
- Roll the Paint:
- Use a roller for even coverage, working in small sections and do not overwork or put on too thick.
- Make sure the paint is applied to the manufacturers stated thickness.
- Apply the first coat in one direction and allow it to dry as per manufacturer guidelines.
- Apply a Second Coat:
- For durability, apply a second coat, rolling in the opposite direction to ensure even coverage.
- Allow to Cure:
- Wait for the paint to dry completely before walking or driving on the floor. Epoxy paints may take up to 7 days to fully cure.
Step 5: Maintain Your Painted Floor
Keep your painted concrete floor looking its best with regular maintenance:
- Clean Regularly: Use a mild detergent and mop to clean the floor. Avoid harsh chemicals.
- Address Spills Quickly: Wipe up oil or liquid spills to prevent staining.
- Avoid Scratches: Use furniture pads and avoid dragging heavy objects across the floor.
FAQs: Painting a Concrete Floor
Q: Can I paint a concrete floor without a primer?
No. A primer ensures proper adhesion and improves durability, especially on untreated porous surfaces.
Q: How long does concrete floor paint last?
With proper preparation and application, epoxy floor paint can last up to 10 years in high-traffic areas.
Q: Can I paint over old concrete floor paint?
Yes, but the old paint must be clean, well adhered to the substrate and abraded to provide a ‘key’ for the new paint to adhere too. Remove any loose or peeling sections before repainting.
Q: What’s the best paint for garage floors?
2-pack epoxy paint is the most durable option for garage floors as it resists oil, chemicals, and heavy vehicles.
