| Construction steps |
| 1.After the interior walls are leveled, they need to be polished to be smooth (the new and old walls should be the same). The color must be uniform. If there are color differences, a layer of covering primer must be applied first until there is no color difference. |
| 2. After the base coat has dried, use the dedicated airless spraying equipment to apply the odorless insulation primer 1-2 times to a thickness of 0.2-0.5mm. When spraying the second layer, wait until the surface of the first layer is dry before proceeding. (The time depends on the ambient temperature; generally, it is 2 hours later.) At the corners, use a soft-bristled brush or a 3.0-inch spray bottle to spray until it is level. The base coat can be diluted by adding 5%-10% water. |
| 3. After the surface dries, apply another layer of 1mm aerogel insulation building type I coating. |
| 4.After the renovation, the indoor temperature during summer is 3-5℃ lower than the ambient temperature, and the perceived temperature drops by 5-8℃. |
