インスタントスプレーセメントで土間コンのひび割れを補修します

We're using Toyo Materan's instant spray cement to repair cracks in a parking lot's concrete floor. It's a spray-type cement repair material. We tried it out at the request of a viewer. Before you know it, the story is a bit iffy, but please enjoy it as an entertaining documentary about amateur DIY. 〇 Used audio sources YouTube - Audio Library https://www.youtube.com/audiolibrary/...
