FacebookHow to spray epoxy resin?
Master smooth, even resin finishes with spray techniques
Spraying epoxy resin is an effective way to protect and beautify a range of surfaces, from art projects and woodwork to floors and driveways. With the right approach, you can create a smooth, high-gloss finish that’s both durable and visually impressive. This guide will walk you through each step, making it easy to achieve professional results—regardless of your experience level.

- “Macote KZ 100” – Gloss Spray Lacquer 400ml – suitable for gloss finishing, scratch-resistance, and UV stability, especially on resin or wood projects.
- “Resinstone” – One-Component Methacrylic Resin for Concrete Floors and Driveways – ideal for airless spray application on concrete for durable, waterproof protection.
- Protective gloves and mask
- Protective sheeting for floors or surrounding surfaces
- Fine sanding pad (optional for intermediate sanding)
Visual Guide: Preparing to Spray Epoxy Resin
Clear and dust-free surfaces are essential for perfect results with spray resin finishes. Visualise your work area, masking off edges, and prepping surfaces for a cleaner spray.
Step 1: Prepare the Surface
Preparation is essential when spraying epoxy resin or protective lacquer. Begin by cleaning the target area so it is free of dust, grease, and debris. Any imperfections or dirt trapped on the surface will be magnified once the glossy finish is applied. If working on wood or a porous surface, ensure it is dry and, if needed, sanded smooth.
Cover adjacent areas with protective sheeting or tape to avoid unwanted overspray. This step helps achieve crisp lines and prevents accidental coverage on nearby surfaces. Strong preparation leads to a cleaner, longer-lasting result.
Step 2: Apply the Spray Coating
Always spray in a well-ventilated area. Shake your spray lacquer thoroughly before use, whether you’re applying 2K Clear Coat Lacquer Aerosol Spray – 400ml High Gloss Finish or “Macote KZ 100” – Gloss Spray Lacquer 400ml. Hold the can or spray gun at the manufacturer’s recommended distance (typically 20–30 cm from the surface).
Work in light, steady passes, moving side to side. Light, even coats prevent drips and streaks. Avoid heavy applications, which can cause runs or pooling.
For larger or absorbent concrete installations, you may use “Resinstone” – One-Component Methacrylic Resin with an airless spray system, ensuring full, even coverage without saturating the surface excessively.
Step 3: Build Layers and Dry Between Coats
Allow each coat to dry as instructed. Most spray lacquers and resins specify waiting times between coats to ensure proper adhesion and a flawless finish. Check your product packaging for drying details.
Once dry, you may lightly sand with a fine pad to remove any minor imperfections before applying a subsequent coat, especially on high-gloss or art finishes. Use gentle sanding between coats for a flawless look.
Repeat this process until you have achieved the desired depth of gloss or protection—typically two to three coats is sufficient for most uses.
Tips and Common Mistakes When Spraying Epoxy Resin
Avoid spraying in humid or dusty conditions. Both can compromise the finish, leaving unwanted marks or dullness. Ensure your workspace is as clean and controlled as possible.
Always wear a mask and gloves to protect yourself from fumes and aerosolised particles. If you encounter rough spots or uneven shine, allow the finish to cure fully before gently sanding and reapplying a thin layer.
Patience between layers pays off. Rushing the drying process risks smudging and a hazy appearance. When spraying outdoors or on large areas, wind and flying debris can be problematic—set up windbreaks or work on still days for optimal results.
