For outdoor performances, when the rainy season arrives, watching the rain hitting the lighting and sound stage must not feel romantic. Rainproof has become a concern for equipment renters. The editor is responsible for stage structure, and in the daily stage sales process, customers often ask if your stage board is waterproof?

We often say that stage boards are waterproof, anti slip, and moisture-proof, is this true? Firstly, we need to understand the structure of stage wooden boards. Stage wooden boards are usually made of multi-layer plywood and bonded with adhesive. Both large surfaces of the stage are coated with waterproof coatings, and one side is pressed into an anti slip pattern.

At present, the stage industry basically adopts this type of stage wooden board with anti slip surface embedded into the stage frame, which appears to have waterproof function on the surface. But the reality may be harsh, that is, wooden products cannot resist water, and the waterproof performance of the board depends on the adhesive used (commonly known as glue) Based on the current prices of stage products on the market, the cost of stage boards must always be selected from the factory price range of 160 yuan or less (let alone the boards used for a stage priced at 200 yuan per square meter on a certain Baoshang platform). The best adhesive used for this price range is Melamine adhesive, which has better waterproof performance than ordinary MR adhesive, but can only be said to resist light rain Encountered heavy rain and high temperature steaming in the later stage, the result was only three words: stop cooking! Namely, do not have any illusions about the waterproof performance of products in this price range, remember: not waterproof!!

So when the rainy season comes, please take preventive measures and try to avoid products being stacked outdoors. If the products have been built outdoors and encounter prolonged heavy rain, please make every effort to provide emergency cover to avoid unnecessary losses caused by rainwater immersion. If they have been soaked in rainwater, please do not expose them to the scorching sun for drying. It is best to place them in a cool and ventilated warehouse for natural drying! (In addition, if the gap between the platen and the aluminum frame allows, transparent structural adhesive<adhesive paper or glass adhesive>can be used to seal, minimizing the probability of water absorption at the edge of the board)
