1. Use solvents and sanders to thoroughly remove rust, paint, old paint and moisture from the surface. (Sanding to remove impurities)
2. The standard mixing ratio of the main agent and the curing agent is calculated as 100:2 according to its weight. (The ratio number of effects is to increase the drying speed of atomic ash)
3. The main agent and curing agent should be prepared until the color of the mixture is uniform. (Stir the curing agent and atomic ash and stir evenly)
4. After training, it should be used within the available time range of 7-10 minutes, which is affected by temperature and humidity. (After stirring well, remember to use it within 10 minutes)
5. The embedded putty should not have bubbles penetrating in, and it must be thoroughly smoothed with a spatula. (When construction, remember to scrape several times Don't produce bubbles, why can't there be bubbles, dear you know hehe)
6. Wait until it is completely hardened before grinding. When the temperature is 20 degrees, it takes more than 1 hour to harden (after the atomic ash is completely dry, it can be sanded, and the drying time is more than 20 degrees 1-3 hours drying The drying time will be affected by the weather, temperature, air humidity, air circulation!) Don't be impatient, slow work, don't worry! ）
7. When the rainy season or humidity is high, the hardening time is appropriately extended. (The weather is bad, the air humidity is high, the drying time will be longer, and the drying will be slower.)
