Substrate Preparation for Polyurea Coating on Speaker Enclosures

Applying polyurea technology to the surface of speaker enclosures offers numerous advantages, such as high application efficiency, environmental friendliness, and excellent impact resistance. During speaker disassembly or transportation, the coating is less likely to chip or peel due to knocks or bumps. Additionally, polyurea cures rapidly, eliminating the need for baking that is typically required with traditional paint.

Before spraying polyurea onto the surface of a speaker enclosure, the following substrate preparation steps are essential:

1.Repair all visible defects on the wood surface, including nail holes, dents, panel edges, and seams, with spot filling or localized patching.

2.Remove any burrs from the wood surface using fine sandpaper, and sand all repaired areas to ensure that the surface and edges of the speaker box are smooth and free of imperfections.

3.Before spraying, handle the speaker cabinet with care. Ensure the rack or surface on which the cabinet is placed is free of debris or hard objects to prevent secondary damage during handling or storage. Use an air gun to thoroughly remove any dust from the surface of the cabinet.
