Ensuring your epoxy primer is thoroughly and accurately mixed is the foundation of a durable, high-performing surface. Let’s explore how to achieve the best results when preparing epoxy primer components.
Mixing the Components: Getting the Ratio Right
Always follow the manufacturer’s specified mixing ratio—commonly stated on packaging or technical data sheets. For Epoxyprimer, this is typically 100 parts resin to 40 parts hardener by weight. Use a clean, dry bucket for best results and ensure no residue from prior projects is present, as contamination can affect curing and adhesion.
Recommended Mixing Techniques
Begin by pouring both components into your mixing container. Stir steadily with a flat paddle or mixing stick, scraping the sides and bottom to ensure uniform consistency. For greater precision—especially with cartridge application systems—a specialist mixer nozzle ensures thorough blending as the epoxy is dispensed. Avoid whipping air into the mix, as excess bubbles can compromise the finished result.
Practical Tips for Smooth Application
Once thoroughly mixed, apply the primer without delay, using a suitable roller or brush. Short-pile or sponge rollers provide even coverage, helping distribute the mix smoothly across the intended substrate. Rapid, even application after mixing prevents premature curing and maximises bond strength on surfaces such as concrete, wood, screeds, or tiles.
When This Matters Most
Precise mixing is crucial when preparing surfaces for resin flooring or decorative coatings, where bond strength and even finish are essential. Properly blending the two parts ensures reliable curing and a stable base for subsequent layers.
