Exposure-type method (existing tile, heat insulating brick, and PU surfaces)

1. Remove old and loose tiles and heat-insulating bricks, then fill and level dents with cement mortar. Damaged areas (or with poor adhesion) of existing PU surfaces and surrounding areas must be scraped off and maintained clean and dry (no puddles should be present).
2. Coating of cracks, parapet angles, and new/old seams may be reinforced by applying 2-3 coats of waterproofing and heat-insulating finish paint.
3. Apply 1-2 coats of powdery silicate cement coating diluted with water (2:1) as a primer. Wait until the following day before continuing with the follow-up waterproofing layer.
4. Apply 3-4 coats of waterproofing and heat-insulating finish paint at 30-minute intervals.
5. Waterproofing materials should be applied in thin layers. Single thick coats are prone to cracking. Special attention must be paid to weather conditions to prevent formation of bubbles/bulges under uncured paint films caused by rain.
