How to Spray Lacquer
Introduction
Spraying lacquer is an attractive finishing technique used on wood and other surfaces, as it offers a rapid drying time, high gloss finish, and excellent durability. When done properly, lacquering can give your project a professional appearance with long-lasting results. In this article, we will explore the step-by-step process of applying lacquer using a spray gun for the best possible outcome.
Materials and Tools
Before you begin spraying lacquer, ensure you have the following materials and tools:
1. Lacquer (choose the appropriate type for your project)
2. Lacquer thinner
3. Spray gun and air compressor
4. Paint strainer
5. Sandpaper (320-grit or higher)
6. Tack cloth
7. Respirator mask
8. Safety glasses
9. Painter’s tape
10. Drop cloths or plastic sheeting
Step 1: Prepare the Work Area
Start by setting up a well-ventilated area, free from dust and debris. Lay drop cloths or plastic sheeting on the floor to protect surfaces from overspray.
Step 2: Prepare the Surface
Before applying lacquer, ensure that the surface is clean and free from any dirt or oils. Smooth out any imperfections with sandpaper of at least 320-grit, then use a tack cloth to remove any dust.
Step 3: Mask Off Any Non-painted Areas
Using painter’s tape, mask off any areas that you do not wish to receive lacquer application.
Step 4: Mix Lacquer and Thinner
According to the manufacturer’s instructions on your specific lacquer product, mix it with an appropriate thinner to create a smooth consistency.
Step 5: Strain the Mixture
Pour the thinned lacquer mixture through a paint strainer and into the spray gun’s reservoir. Straining the lacquer prevents any debris from clogging the spray gun nozzle during application.
Step 6: Set Up Your Spray Gun
Connect your spray gun to the air compressor and adjust the settings according to the manufacturer’s recommendations. Make sure to have both a respirator mask and safety glasses on before you start spraying.
Step 7: Apply the First Coat
Hold the spray gun about 10-12 inches away from the surface. Start with a thin, even coat of lacquer using smooth, overlapping strokes. Horizontal strokes are usually best for horizontal surfaces, while a vertical motion is suitable for vertical surfaces.
Step 8: Allow Each Layer to Dry
Let each coat of lacquer dry for around 30 minutes or as advised by the product instructions, rub down gently with a fine-grit sandpaper between coats, and then wipe clean with a tack cloth.
Step 9: Add Additional Coats
Repeat steps 7 and 8 until you’ve applied three to four coats of lacquer (or more, depending on your desired finish)
Step 10: Clean Up
Once the final coat has dried completely, remove all painter’s tape and carefully dispose of it. Clean your spray gun thoroughly according to the manufacturer’s recommendations, ensuring it’s ready for future use.
Conclusion
Spraying lacquer can be a straightforward process when you follow these steps carefully. With proper technique and quality materials, you’ll achieve a professional and durable finish that will showcase your woodworking or other projects beautifully.
