The Nano L spray method introduced in our channel is a polyurea waterproofing method developed by Construction New Technology No. 867 by stc

The Nano L spray method is a waterproofing method that uses ultra-high-speed polyurea and applies mechanised construction throughout the entire process, and is a rooftop exposed double-layer waterproofing method that can be quantitatively compounded at room temperature by applying a cascading lattice-type transfer mixing device to the middle work to integrate a soft type ultra-high-speed light waterproofing material that is easy to respond to the concrete base surface and a hard type ultra-high-speed light waterproofing material that secures external impact resistance and durability.

Construction New Technology No. 867 Nano L spray waterproofing method is the best waterproofing method in existence that has been proven to be excellent for applying polyurea waterproofing to schools and government offices.
look forward to your viewing pleasure.
