Exposure-type method (existing paint surfaces)

1. Remove all objects, dust, and loose material from the construction surface.
2. Apply one coat of oil-based ultra-strong primer curing agent and wait for 30 minutes before applying the next coat.

(Reminder: the layer of applied primer curing agent must be thin to avoid wrinkling of the old paint film and uneven coating).

3. Apply 2 coats of mid-coat waterproof coating to the whole external wall surface at 30-minute intervals.
4. Upon application, apply two thin coats of waterproofing and heat-insulating finish paint.
5. All surfaces must be completely covered to prevent peeling off or bubble formation caused by seepage on the sides. Special attention must be paid to weather conditions to prevent formation of bubbles/bulges under uncured paint films caused by rain.
