Sika Epoxy Flooring System

Epoxy flooring is a system, not a single product. Get the layers right and you'll have a floor that lasts decades. Get them wrong and you'll be grinding it back within a year. Use this guide to build your cart with confidence.

Step 1: Primers & Moisture Barriers

The secret to a lifelong floor is the bond between the resin and the concrete. Never skip the primer.

• Sikafloor 158W Fast Barrier:  If your concrete is "green" (less than 28 days old) or shows signs of rising damp. This creates a waterproof seal so your epoxy doesn't "bubble" from ground moisture.

• Sikafloor 161: The industry standard for almost every project. It is a high-strength primer that "bites" into the concrete, ensuring your colored coats stay stuck forever.

• Sikafloor 94: A low-viscosity, multi-purpose epoxy. Use this as a fast-curing primer or mix it with sand to create a "patching mortar" to fix cracks in your floor before coating.

Step 2: Base & Intermediate Coats

This is where your floor gets its thickness, durability, and primary color.

• Sikafloor 264: This is a high-build, colored epoxy resin. It is incredibly tough, chemical resistant, and easy to roll. If you want a solid-colored floor (Grey, White, etc.), this is your main coat. 

Step 3: UV Protection & Top Coats

Standard epoxy can "yellow" or "chalk" if exposed to sunlight. The right topcoat protects your investment and adds extra scratch and chemical resistance. Choose based on your system:

For Solid Colour Systems (over Sikafloor 264):

• Sikafloor 359 Clear: A tough-elastic, clear polyurethane topcoat. Recommended if your floor is near a roller door, large windows, or any natural light source — adds UV protection and a beautiful satin finish over your 264 base coat.
• Sikafloor 550 PA Clear: A polyaspartic coating that is ultra-UV stable, extremely scratch-resistant, and fast-curing. Perfect for commercial workshops or any project that needs to be back in service quickly.

For Decorative Flake Systems (over broadcast flakes):

• Sikafloor 169: A 100% solids clear epoxy used exclusively in the flake system — applied in two coats. The first coat seals and encapsulates the broadcast flakes; the second coat is the final topcoat for a smooth, durable finish.

Protrade Warehouse Tip: Preparation is everything! Always grind your concrete surface to a "sandpaper-like" texture before applying your first coat. An epoxy system is only as strong as the surface it bonds to.
