We would like to introduce the "Damo Square Lead Renovation Drain" handled by Yamato Co., Ltd. The "Damo Square Lead Renovation Drain" is a product that has undergone a model change from the previous Damo renovation drain. It is available in two types, N (Normal) and S (With Sand), allowing for selection based on application, and it accommodates various waterproofing methods. Additionally, it has been improved to allow for easier hose insertion compared to conventional products, and the flange part has been redesigned to a rounded shape. ■ Features of the Damo Square Lead Renovation Drain N (Normal) The flange part is made of raw lead, allowing it to be used with various waterproofing methods when a metal primer is applied. ■ Features of the Damo Square Lead Renovation Drain S (With Sand) The surface of the lead flange is treated with our unique sand coating process, which allows for stable adhesion of the waterproof coating using general substrate primers, as opposed to the usual requirement of using a metal primer for lead. This eliminates the need to differentiate primers during installation around the drain, thereby improving work efficiency.
