Which time period is good for outdoor guardrail to brush enamel?

It is best to choose the season or time when the temperature is slightly higher and the air is dry, such as summer and autumn. Drying is beneficial to improve the adhesion of paint to the wall and paint layer, and the paint on the paint is not easy to change color. High temperature can accelerate the drying of paint, which dries quickly and has less dust.

Expressway guardrail is the main facility to ensure driving safety. The guardrail plate is made of galvanized steel plate, which has certain corrosion resistance. However, exposure to rain, dust and tail gas in long-term use will cause serious corrosion, so painting is a common protective measure. After the galvanized sheet is galvanized, the characteristics of the substrate are not used by ordinary carbon steel iron plates, and it becomes very smooth, which makes the adhesion of many paints difficult to attach, which easily causes the problem of paint film falling off, and does not play an anti-corrosion role at all. For the coating of galvanized sheet, special primer is needed to improve the adhesion of the coating. ED 1000 epoxy primer has excellent adhesion and good performance on smooth metal surface.
