Step-by-Step: Applying Mr. Surfacer 1000 for a Smooth Base Coat

Quick Answer

For a smooth, even base coat on your Gunpla, use Mr. Surfacer 1000 in thin, overlapping passes from about 15 cm away, and let it cure fully before sanding.

Step-by-Step Application

1. Prepare your workspace and parts: Choose a well-ventilated area and lay down a drop cloth. Wash your parts in warm soapy water, rinse, and let them dry completely. Sand lightly with 800-grit paper to remove any gloss. Check that parts are completely dry before you start spraying.
2. Shake the can thoroughly: Shake the Mr. Surfacer 1000 can for at least 2 minutes to ensure the pigment is fully mixed. Test spray on a piece of scrap to confirm a fine, even mist. If the spray sputters, shake longer and clean the nozzle.
3. Spray in thin, overlapping passes: Hold the can about 15 cm from the part. Apply a light first pass, then a second pass at a 45-degree angle to cover all surfaces. Keep the can moving to avoid pooling. Multiple thin coats beat one thick coat—avoid drips and runs.
4. Let it cure and inspect: Allow the primer to dry for at least 24 hours. Inspect the surface under good light; the dark gray color will reveal any remaining scratches or imperfections. If you see flaws, sand them lightly and apply a touch-up coat.
5. Polish if needed: For a glass-smooth base, polish the cured primer with a fine polishing cloth or waterproof paper. This is especially useful before applying metallic or gloss paints. Don't over-polish—stop once the surface is uniform and smooth.
