For ordinary environments (C2-C3 mild to moderate corrosion), the following water-based topcoats with high cost performance and strong adaptability are recommended.: Water-based alkyd topcoat is the most common and economical choice. It is suitable for use with water-based alkyd anti-rust primer. It is easy to apply, fast drying, and has balanced anti-rust and weather resistance. ; It has rich color options, high gloss, good decorative properties, and is affordable.

The easiest type of water-based acrylic paint for bottom surface to apply. No separate primer is needed. It can be directly coated on the treated substrate. It can meet the needs of anti-rust protection and decoration at the same time, and the construction process is reduced by 50%. ; The anti-corrosion and weather resistance meets the requirements of ordinary environments, and the color selection is diverse. It is suitable for scenes such as renovation of ordinary steel structures and protection of temporary facilities that require high construction efficiency. Water-based acrylic polyurethane topcoat is an advanced choice for performance. It has better weather resistance and anti-discoloration in ordinary environments than alkyds.
